Abstract: The AEC industry is nowadays one of the most hazardous industries in the world. The construction sector employees about 7% of the world’s work force but is responsible for 30-40% of fatalities. As statistics demonstrate, interferences between workers-on-foot and moving vehicles have caused several injuries and fatalities over the years. Despite safety organizational measures, passive safety devices imposed by regulations and efforts from training procedures, scarce improvements have been recorded. Recent research studies propose technology driven approaches as the key solutions to integrate standard health and safety management practices. This is motivated by the evidence that the dynamics of complex systems can hardly be predicted; rather a proactive approach to health and safety is more effective. Current technologies installed on construction equipment can usually react according to a strict logic, such as sending proximity alerts when workers and equipment are too close. Nevertheless, these approaches barely do make informed decisions in real-time, e.g. including the level of reactiveness of the endangered worker. In similar circumstances a digital twin of the construction site, updated by real-time data from sensors and enriched by artificial intelligence, can pro-actively support activities, forecasting dangerous scenarios on the base of several factors. In this paper a laboratory mock-up has been assumed as the test case, supported by a game engine, which is able to replicates the job site for the execution of bored piles. In such a scenario populated by an avatar of a sensor-equipped worker and a virtual driller, a Bayesian network, implemented within the game engine and fed in runtime by sensor data, works out collision probability in real-time in order to send warnings and avoid fatal accidents.

Abstract: In the wide context of facility management, several processes, such as operations, maintenance, retrofitting, and renovations, ensure that buildings comply with the principles of efficiency, cost-effectiveness, and indoor comfort. Apart from ordinary operation, facility management is responsible for the renovation of and long-term performance improvement of building facilities. In such a scenario, the cyber—physical system (CPS) paradigm with holonic architecture, which is the focus of this study, can successfully guide the operation management and long-term refurbishment processes of buildings. Analogous to the manufacturing field, the developed CPS maximizes holons’ self-configuration and self-organization and overall throughput effectiveness metrics to detect the best corrective actions toward system improvements. Consequently, suggestions and lessons learned from the evaluation of building efficiency are redirected to the building information model. Hence, the digital model acts as a repository of currently available equipment for operations management and the history of diagnoses that support decision-making during the maintenance, retrofitting, and renovation processes. Evidently, the repeated detection of a specific issue, which is unaffected by operations management, should be considered an opportunity to act and enhance the performances of existing building components. Similar to a goods-producing industry, the building management system developed in this study applies the aforementioned methodology to provide services related to indoor comfort and building health. This approach indicates that a method for automatic real-time diagnosis is tested in a case study consisting of a multi-use and large public building. The current paper, which is an extended version of the one presented in the Creative Construction Conference 2018, deepens the decision support tool and the supervision policy. Moreover, the developed system is contextualized by providing an example of use case and highlighting the step forward in the field of smart buildings.

Abstract: The Architecture, Engineering and Construction (AEC) industry is still one of the most hazardous industries in the world. Researchers impute this trend to many factors such as the separation between the phases of safety planning and project execution, implicit safety issues and, most of all, the dynamic and complex nature of construction projects. Several studies show that the AEC industry could greatly benefit of latest advances in Information and Communication Technologies (ICTs) to develop tools contributing to safety management. A digital twin of the construction site, which is automatically instantiated and updated by real-time collected data, can run fast forward simulations in order to pro-actively support activities and forecast dangerous scenarios. In this paper, the twin model of the Digital Construction Capability Centre (DC3) at the Polytechnic University of Marche (UNIVPM) is developed and run as a mock-up, thanks to the adoption of a serious game engine. This mock-up is able to mirror all the relevant features of a job site during the execution of works from a safety-wide perspective. In such a scenario, virtual avatars randomly explore the construction site in order to detect accessible, unprotected and risky workspaces at height, while warning the safety inspector in case additional safety measures are needed.

Abstract: Nowadays digitalization is a growing challenge for the whole construction sector. Therefore, the need of supportive tools and procedures is becoming increasingly urgent in each construction project step and particularly for project supervision in the execution phase. This is a primary requirement especially for the public sector, since the legislative framework is becoming more and more focused on this aspect, in Italy as well as in the European and international context. A formalization of the inspection procedures of project management in the construction phase is proposed through Business Process Modelling and Notation (BPMN) 2.0 language. The first key aspect of this proposal is to assume a model-based approach, which allows a more coherent information management, in contrast with the traditional document-based one. The second aspect concerns process modeling. In fact, the proposed method is based on processes, instead of BIM – based federated object-oriented models. Construction processes are modelled so that they can generate and feed the federated models themselves. In addition to this, Business Process Modelling and Notation can be used to create a collection of different procedures involved in the inspection management for construction projects. Also, BPMN model will allow an automatic feeding of an inspection management support system which will be developed in future studies, that will offer the full traceability of the procedures and the delivery of the quality certification of products. The case study of the inspection of ready-mix concrete cast-in-place process is analyzed and discussed.

Abstract: Building assets surveys are cost and time demanding and the majority of current methods still rely on manual procedures. New technologies could be used to support this task. The exploitation of Artificial Intelligence (AI) for the automatic interpretation of data is spreading throughout various application fields. However, a challenge with AI is the very large number of training images required for robustly detect and classify each object class. This paper details the procedure and parameters used for the training of a custom YOLO neural network for the recognition of fire emergency assets. The minimum number of pictures for obtaining good recognition performances and the image augmentation process have been investigated. In the end, it was found that fire extinguishers and emergency signs are reasonably detected and their position inside the pictures accurately evaluated. The use case proposed in this paper for the use of custom YOLO is the retrieval of as-is information for existing buildings. The trained neural networks are part of a system that makes use of Augmented Reality devices for capturing pictures and for visualizing the results directly on site.

Framework based on building information modeling, mixed reality, and a cloud platform to support information flow in facility management
FRONTIERS OF ENGINEERING MANAGEMENT
Autore/i: Naticchia, Berardo; Corneli, Alessandra; Carbonari, Alessandro
Classificazione: 1 Contributo su Rivista
Abstract: The quality of information flow management has a remarkable effect on the entire life cycle of buildings. Manual retrieval of technical specifications and features of building components and their performance assessment leads to increased cost and time and efficiency reduction, especially during the facility management (FM) stage. The introduction of building information modeling (BIM) in the construction industry can provide a valuable means of improving the organization and exchange of information. BIM tools integrate multiple levels of information within a single digital model of a building. Nevertheless, the support given by BIM to FM is far from being fully effective. Technicians can benefit from real-time communication with the data repository whenever the need for gathering contextual information and/or updating any data in the digital model arises. The framework proposed in this study aims to develop a system that supports on-site operations. Information requirements have been determined from the analyses of procedures that are usually implemented in the building life cycle. These studies set the standard for the development of a digital model of a building, which will be shared among various actors in charge of FM and accessed via a cloud platform. Moreover, mixed reality is proposed to support specific information that is relevant to geometric features and procedures to be followed by operators. This article presents three use-cases supported by the proposed framework. In addition, this research article describes the first proof of concept regarding real-time support for FM.

Augmented Reality and Deep Learning towards the Management of Secondary Building Assets
Proceedings of 36th International Symposium on Automation and Robotics in Construction
Autore/i: Corneli, A.; Naticchia, B.; Carbonari, A.; Bosche, F.
Classificazione: 4 Contributo in Atti di Convegno (Proceeding)
Abstract: The retrieval of as-is information for existing buildings is a prerequisite for effectively operating facilities, through the creation or updating of Building/Asset Information Models (BIM/AIM), or Digital Twins. At present, many studies focus on the capture of geometry for the modelling of primary components, overlooking the fact that many recurring actions need to be conducted on assets inside buildings. Furthermore, highly accurate survey techniques like laser scanning need long offsite processing for object recognition. Performing such process on site would dramatically impact efficiency and also prevent the need to revisit the site in the case of insufficient/incomplete data. In this paper, an Augmented Reality (AR) system is proposed enabling inventory, information retrieval and information update directly on-site. It would reduce post-processing work and avoid loss of information and unreliability of data. The system has a Head-Mounted Display (HMD) AR interface that lets the technician interact handsfree with the real world and digital information contained in the BIM/AIM. A trained Deep Learning Neural Network operates the automatic recognition of objects in the field of view of the user and their placement into the digital BIM. In this paper, two uses cases are described: one is the inventory of small assets inside buildings to populate a BIM/AIM, and the second is the retrieval of relevant information from the AIM to support maintenance operations. Partial development and feasibility tests of the first use case applied to fire extinguishers, have been carried out to assess the feasibility and value of this system.

Classificazione: 4 Contributo in Atti di Convegno (Proceeding)
Abstract: Emergency management can benefit from advanced information and communication technology (ICT), since it can support officers in charge of emergency management to deal with urgent decision within a really short deadline. Further enhancement can derive from the application of holonic systems, which typically deal with the unexpected. In fact, unexpected events may prevent the application of emergency plans, e. g. evacuation of people outside of a building in fire through a network of pre-determined paths. The holonic emergency management system, proposed in this paper, guarantees the shift to a contingent approach, leveraging the flexibility and adaptability to changing scenarios deriving from the holonic theory. Last but not least, the BIM integration provides all the building’s topological information. Such a technology can exploit general data to automatically detect unconventional ways out and arrange rescue operations in real-time. The developed system has been applied to the fire safety management of a large building in a university campus. The BIM model of the case study has been imported in a game environment where an unconventional pathfinding has been experienced.

Classificazione: 4 Contributo in Atti di Convegno (Proceeding)
Abstract: Emergency management can benefit from advanced information and communication technology (ICT), since they can support officers in charge with rescue operation to deal with urgent decision within a really short deadline. Further enhancement can derive from the application of holonic systems, inherited from the manufacturing industry, to tackle unforeseen scenario. The aim of this research is to develop a BIM-integrated technology for the real-time pathfinding during emergencies. A virtual reality platform, exploiting building topological data from the digital model, can support the standard Emergency approach if an unexpected event voids the network of predetermined paths. The developed system has been tested in a large mixed-used building assumed as case study.

Holonic execution system for real-time construction management
AUTOMATION IN CONSTRUCTION
Autore/i: Naticchia, B.; Carbonari, A.; Vaccarini, M.; Giorgi, R.
Classificazione: 1 Contributo su Rivista
Abstract: The latest advances in construction management are leading towards the transition from traditional activity-based to flow-based management, which imposes that a set of flows be considered to reach efficiency. In addition, planning can no longer be limited to the pre-execution phase, because the variability and contingencies that are always encountered in the execution phase ask for close monitoring and dynamic planning of construction works. These issues have been the subject of well-known research advances, among which, in this paper, online planning and Last Planner System are cited. The core of these approaches is that work progress must be regularly monitored and some decision making models must be available to site managers for them to be able to redirect the work plan during execution. However, this approach is so demanding in terms of communication, computational burden and team collaboration that automation was claimed as the right approach to make it feasible. In this paper it is suggested that holonic management systems can either perform automatic construction site management or support site managers, depending on the level of embedded intelligence. Such systems combine the potentials of hierarchical and heterarchical systems and are capable of self-organisation and multi-objective optimisation. They are designed so as to reason both at a local and global level. As a result, they are safe and do not suffer communication losses or delays. They correctly simulate real world interactions among all the agents typically involved in construction execution and management. A preliminary application for the real-time management of the execution of bored piles in a middle-sized construction site through a holonic management system is presented. Both the system architecture and a possible development platform are defined, so as to assess the potentials of this approach.

A DECISION SUPPORT SYSTEM FOR MULTI-CRITERIA ASSESSMENT OF LARGE BUILDING STOCKS
JOURNAL OF CIVIL ENGINEERING AND MANAGEMENT
Autore/i: CARBONARI, Alessandro; CORNELI, ALESSANDRA; Martino DI GIUDA, Giuseppe; RIDOLFI, LUIGI; VILLA, Valentina
Classificazione: 1 Contributo su Rivista
Abstract: Both public administrations and private owners of large building stocks need to work out plans for the management of their property, while having to deal with yearly budget limitations. Particularly for the former, this is a rather critical challenge, since public administrations are given the responsibility of sticking to very strict budget distributions over the years. As a consequence, when planning the actions to be taken on their building stocks in order to comply with their current use and the legislation in-force, they need to classify refurbishment priorities. The aim of this paper is to develop a first tool based on Bayesian Networks that offers an effective decision support service for owners even in case some information is incomplete. This tool can be used to evaluate the compliance of existing buildings with the latest standards. The decision support platform proposed includes a multi-criteria evaluation approach combining several performance indicators, each of which related to a specific regulatory area. This tool can be applied to existing buildings, where the building with the lowest score shows the highest priority of intervention. Also, the platform performs an assessment of expected costs for required refurbishment or renovation actions.

Classificazione: 1 Contributo su Rivista
Abstract: Digitalised models can play a key role in the management of building life-cycle. This paper focuses on the challenges connected to the operation phase of buildings, when the adoption of BIM can make information retrieval and management easier and more efficient. More specifically, a BIM-based cyber-physical system for the automated monitoring of buildings during their regular operation is proposed and tested by means of a customised simulator. The system automatically works out key performance indicators based on the overall throughput effectiveness (OTE) metric, assessing both the overall efficiency and the efficiency of every sub-system integrated in the building. Thus, assessments of the contribution of every sub-system to the operation of the building are performed in real-time. In addition, the metric proposed can help manage multi-objective real-time control. The system is self-reconfigurable thanks to the self-similarity assumption of the computational structure that is designed as a holarchy of holonic systems. The first application reported in this paper shows that when intelligence is embedded at both lower and higher levels, it is possible to generate information that is then used to update the digital model, developed as a BIM. As a result, the digital model becomes the mirror of the physical system and stores the actual performances recorded by the building to support facility managers in making decisions.

Abstract: Project schedules in construction are responsible for an efficient deployment of resources on the job-site and for the overall efficiency of work progress. Current approaches too often lead towards sub-optimal work plans or, sometimes, even scarce productivity. For that reason, a lot of research was devoted to the development of automated scheduling tools, which can provide optimal solutions while requiring reasonable computational effort. As a consequence, planners can save their time and involved resources can benefit from the efficient organization of work packages and tasks. However, automation in construction scheduling is a tough challenge, because it requires to generate and optimize multi-objective problems, which usually include several parameters. In addition, deviations from what expected is quite frequent, and these algorithms should be able to quickly revise the previous plan, in fact performing dynamic planning. Hence, this paper presents an agent-based approach, which can be integrated in a BIM-based platform to perform automated scheduling of construction works. The BIM component can provide instant access to relevant information, which must be integrated with some user defined inputs, in order to feed the optimization algorithm. This algorithm was based on the multiple ant colony system for vehicle routing problems with time windows, because it can handle several resources travelling through many locations, each one performing its task, even in the presence of time constraints. The optimization was performed with respect to both overall makespan and total costs. An application to the case of bored piles execution will be presented in this paper.

As a matter of fact, the repeated detection of a specific issue, since not affected by operations management, should be read as an opportunity to act and enhance the capabilities of buildings components. According to this approach, an automatic real-time diagnosis method is tested in a test case consisting of a multi-use and large public building.

Classificazione: 4 Contributo in Atti di Convegno (Proceeding)
Abstract: While on the one hand the BIM methodology is an essential reference for the construction of new buildings, on the other hand it is receiving particular attention and interest also from owners of large building stocks who want to take advantage of the benefits of Building Information Modelling so as to have a coordinated system for the sharing of information and data. This, especially in a process that concerns the management and maintenance of a large building stocks, involves the processing of uncertain information in BIM, particularly when dealing with existing buildings, due to the lack of and/or incomplete documentation, entailing a significant investment in terms of time and additional costs. Therefore, to represent the reliability of existing building data, we suggest introducing a tool based on Bayesian Network that offers a valid decision support under conditions of uncertainty and is used to evaluate the compliance with the latest standard. This paper presents a process to provide an integrated database defined by a minimum information level that can be used both to extrapolate and query specific information from a digital building model and populate the decision model in order to evaluate the performance parameters of existing buildings which is based on a Multicriteria decision making approach (AHP).

Mixed Reality Approach for the Management of Building Maintenance and Operation

Classificazione: 4 Contributo in Atti di Convegno (Proceeding)
Abstract: Building Information Modelling (BIM) has been indicated as the right tool to provide the construction industry with the productivity boost that has been lacking in the last 40 years. This momentum finds its highest fulfilment in the support provided by BIM models to knowledge management and the automation of process. However, the management of information flow is still far from its automation breakthrough and, as far as operation and maintenance are concerned, knowledge about procedures is often incomplete. Moreover, processes are often do not undergo optimisation and the individual steps to be performed are not communicated, but in facility management (FM) the transmission of know-how is fundamental particularly because some operations are dangerous or risky. In this framework, Mixed Reality (MR) represents a powerful means to communicate the correct data concerning both geometric features to be considered and the standard procedure to be followed. The aim of this paper is to investigate the possibility of exploiting the benefits provided by these technologies to achieve automation in the transmission of information and optimisation of procedures, improving efficiency and productivity thanks to a better understanding of the operations to be carried out and the reduction of errors. With the support of a head-mounted display (HDM) device with a see-through screen capable of presenting 3D virtual objects, this research tries to combine information from a BIM model with reality to study the benefits for maintenance personnel.

Abstract: Inefficient control of information flow in projects is one of the critical aspects that affects the entire lifecycle of buildings. Besides allowing for a simpler and more efficient transfer of information, the dramatic growth of the digitalization process in the AEC industry underlines the need for a common data environment, which manages and shares these data. The increasingly widespread adoption of Building Information Modeling (BIM) is partially leading to a union of multiple levels of information in a single digital model of the building. However, many challenges are still posed in terms of information transfer from the model to operators responsible for keeping building functioning and in good conditions. In fact, technicians could benefit from the immediate availability of data on the current state of buildings and from the level of information detail that can be obtained from digital buildings. The purpose of this work is to create a framework for data management related to the maintenance phase of the building asset. Starting from the study of maintenance processes it was possible to define the information needs that will be managed by a common data environment support associated with BIM models of buildings. Furthermore, thanks to the aid of Mixed Reality (MR), the flow of information is transferred directly to the last user both as regards geometric features and for the standard procedure to be followed. This will allow a maximum optimization of data management procedures due to an automation of processes that will result in a lower incidence of errors in the processes leading eventually to an increase in quality and productivity.

Editore: Intech
Luogo di pubblicazione: London
Classificazione: 2 Contributo in Volume
Abstract: This chapter focuses on advanced tools for transient energy simulation of existing buildings. Budget constraints often hinder the possibility of implementing large-scale retrofit projects. As a consequence, designers must work out low-cost renovation, which asks for a deep knowledge of the current state of the buildings. Furthermore, the performances of heating plants in existing buildings can be enhanced through the improvement of the control of the system. These types of retrofit actions can be carried out with a limited budget, but asks for the availability of very accurate transient energy simulation tools, which can compare the current and the renovated scenarios. On top of them, cost–benefit analyses can be developed. In this chapter, a model of a small hospital is developed in the Dymola/Modelica environment. The high flexibility of the transient simulation model and the very good agreement between numerical estimations and measurements are shown. Then, one scenario regarding enhanced regulation of the heating system by means of a customized ambient temperature control system is developed, and the expected energy savings are estimated.

Abstract: This work reviews and recaps some lessons learnt in the industrial cyber-physical systems playground to indicate a viable path towards an effective use of artificial intelligence in distributed automation. The holon concept is used as a pivotal tool towards a simplification of the design and implementation of architectures that exploit recursive patterns and self-similarities to keep the industrial systems-of-systems problem under control, whilst addressing the consistent coupling between the physical environmental and the reasoning processes. The Beer’s viable system model is used as an inspiration towards new viable holistic visions of the production system-of-systems.

Abstract: Ensuring high efficiency in construction through advanced planning techniques must be supported by the simulation of construction processes. In previous research, the potential for multi-agent based simulation to support the planning phase were successfully shown with regard to some typical construction tasks. Among the main benefits determined by this approach the following ones were reported: capability of simulating real-world processes and interaction among resources; powerful 3D visualization; optimal sizing of resources. However, those models are not easy to create, because of the absence of built-in blocks and the many relationships among single agents and between agents and context. In this paper we propose the application of a novel holonic system for construction management, which is a sub-category of multi-agent systems. It combines the high and predictable performance promised by hierarchical systems with the robustness against disturbances and the agility of heterarchical systems. Holons are self-contained, stable, intermediate forms, that can be used to create a bigger whole. By using holons, designers aim to create complex systems that can be reused and redesigned much more rapidly than standard multi-agent systems. The approach was applied to the optimal scheduling of bored piles construction. Hence, a holonic construction execution system for bored piles tasks was developed. The holonic architecture was designed so as to integrate the DMAS pattern for scheduling optimization through stigmergy. The results of this paper showed the easy reusability of our simulation sub-systems and the potentials in terms of automatic optimal planning of construction works.

Abstract: This paper gives a novel perspective about the role of the self-similarities in the modelling of system of systems with cyber-physical representation. With the adoption of virtual overlays of dynamically self-adapting holarchies, the emergent characteristics and behaviors of the information and automation systems are mapped into a recursive tree of autonomic components that can be typically realized through holonic multiagent systems. The nested computing structures that are used to achieve a productivity goal are kept simple by means of self-similarities. This simplification provides a viable methodology for the pervasive management and the automated programming of the holonic components. The technique described is suitable for a prompt adoption on a vast class of manufacturing, robotics, mechatronics, and facility management processes, whilst enabling a continuum between humans and machines. An advantage of the proposed method is its agnosticism with respect to most of the specific but heterogeneous technological means adopted in the already existent automation realizations.

Abstract: Building management systems monitor and control building performances in real-time. Most control systems, which have been developed in the last decade, achieve the required performances relying on a centralised and hierarchical framework. In the regular operation phase, these systems are usually able to efficiently reach their goals, whereas they often fail to stick to pre-determined targets in the presence of unforeseen disturbances. As a matter of fact, traditional control systems suffer complex unforeseen scenarios that cannot be modelled by the analytics and knowledge integrated in these systems, because hierarchical systems strive to keep full control at any level. As an alternative, holonic management systems, which have been successfully applied in the manufacturing field, can tackle this type of drawbacks. The flexibility of their elementary units, the holons, makes it possible to avoid the rigid structure of hierarchical systems so as to respond quickly to disturbances and dynamically re-arrange their structure. In this paper, a first holonic computing structure is developed for indoor comfort management in an office room. The structure developed can drive both the operation management phase and the medium- and long-term measurement of performances. The former is implemented by means of a sequence of specific minimum cost actions which is based on the overall throughput effectiveness (OTE) metrics. The latter exploits the same OTE metrics to suggest corrective and improvement actions. Finally, OTE diagnoses are re-directed to a BIM model to support decision making for long-term improvement actions on the building facility.

Abstract: The management of any large building stock with limited resources poses a problem of prioritization of refurbishment actions. Also, available technical information about the building stock is often incomplete and the process of standardization and updating is expensive and time consuming. Some public owners are developing preliminary BIM models of their stock, but they are willing to limit the complexity of the models within the lowest amount of information required for management and maintenance, so as to make that process affordable. Indeed, administrations are challenged by their duty relative to planning regular maintenance and operation of buildings, because of the legislation in force, which requires monitoring of their facilities. For the reasons stated above, this paper presents a decision support tool that can help prioritize refurbishment actions on large building assets. To this purpose, many requirements must be jointly considered in this examination, each requirement being assessed by means of one or several indicators. Then the indicators are compared one another, according to a multi-criteria approach, that weighs the several criteria and rank the assets. In order to deal with the extensive and uncertain information that must be managed in this process, indicators are estimated by means of Bayesian Networks. This tool is used first to assess the technical indicators and rank the assets, while marking any facilities not complying with regulations. Then, additional Bayesian Networks are in charge of estimating the budget needed to upgrade non-compliant facilities with minimum legislation requirements. The outcomes of this research can be used even to assess the level of detail of the information that must be included in BIM models of the stock, in fact acting as guidelines for their development. Finally, the application of the decision tool on a real test case will be presented.

Classificazione: 1 Contributo su Rivista
Abstract: In this paper a model for the dynamic simulation of fans used in mechanical air supply systems is described. Thanks to this model, the behavior of fans subject to control by variable frequency drives (VFD) can be predicted, which includes power absorbed by the fan and expected ventilation rates. Hence, it can help design energy control systems for buildings. The proposed model was based on the Modelica language and was developed from the dynamic phasor domain representation, because this representation is a trade-off between the basic non transient representation, that is computationally efficient but cannot describe fan dynamics, and the dynamic time domain model, that is the most representative one but computationally very demanding. A comparison among these models showed that, within fan frequency variations typical of ventilation systems in buildings, the phasor domain model is as representative as the more complex dynamic time domain model in terms of prediction of the dynamic behavior, that is neglected by the basic non transient model. Moreover, the new phasor domain model was validated against measured data relative to a fan installed in a subway station in Barcelona. Thanks to this model, energy consumption of dynamically driven fans can be estimated at the simulation stage, at the expense of a reasonable computational effort.

Abstract: Owners of any large building stock, such as public administrations, usually have to manage a huge variety of buildings with a limited budget. For this reason, targeted refurbishing actions are needed to ensure that those buildings comply with the latest standards, to preserve the stock and also keep it in good condition. As a result, most public administrators have to make important decisions regarding what part of their stock should be refurbished first. In this paper a new methodology regarding an objective assessment of the quality of large building stock is suggested, as it could help prioritize refurbishment actions. The methodology is based on a decision support system, that is capable of semiautomatically evaluating the compliance of existing buildings with a set of rules by means of the application of Bayesian Networks. The main findings of this research led to the identification of relevant parameters to be used for that assessment; the re-use of those parameters to build a multi-criteria analysis tool; the identification of criteria and requirements to interface this decision tool with BIM models of the stock under consideration. A rough estimation of costs needed to refurbish those buildings that are not compliant, in order to include budget concerns, will be dealt with in the next research step. Finally, a preliminary application of the decision support system to evaluate two Italian school buildings – selected as case studies - will be reported.

Abstract: Some public buildings, which date back to the 1980-1990s, often miss to comply with comfort basic requirements. Also, their energy consumption is often above thresholds posed by regulations presently in force. Hence, low-cost technology improvements for renovation with high return on investment is a good opportunity in order to limit the required budget. To this purpose, the integration of advanced control policies may optimize energy use of buildings with minimum hardware enhancement. In this paper, we evaluated the performances of an existing building that belongs to the campus of the Università Politecnica delle Marche (Ancona, Italy), and that is made of offices, teaching rooms, laboratories, a library and other public spaces. Thanks to an extensive monitoring of indoor comfort conditions, the main inefficiencies in terms of comfort were analyzed and a Dymola model of the actual building was worked out. Then, some energy improvement actions were assumed and tested by means of numerical simulation in the Dymola environment, and the benefits in terms of comfort and energy saving were estimated. Meanwhile, a BIM model of the building was built, regarding both the present status and each improved scenario, that allowed to perform a detailed cost estimation of each scenario. As a result, a cost-benefit analyses of each renovation scenario was performed and all the options were compared. The analyses showed that some renovation actions could be supported by energy savings with reasonable return on investment.

Abstract: An energy audit is a standard process to support the decision-making in the area of energy management. Nevertheless, an energy auditor does not succeed as easily and quickly in identifying all the energy streams in a facility in order to decide whether retrofitting the audited object is beneficial. In fact, energy auditing of buildings is usually a time consuming and expensive process, due to efforts required for data collection and modelling of audited objects. Therefore, a decision-making tool should support the modelling phase and this purpose might be achieved by means of reduced-order modelling, after a quick data acquisition, through on-site measurements. As highlighted in literature, reduced-order models, also called grey-box models, showed their reliability to achieve a suitable description of the thermal response of buildings in a short time. Besides, they are more cost-effective and their thermal parameters can be usually extracted in short time. Consequently, deriving a lumped parameter model, by means of measurements collected in a rather short period, could allow the owners and managers of real estates to perform fast and cheap preliminary assessment on the opportunity to implement energy renovation actions. Starting from a test performed in the machine laboratory of our department at the Universit? Politecnica delle Marche, the investigated empirical procedure for deriving grey-box models will be provided and energy saving opportunities, within an energy retrofit, will be analysed as an example about the application of this procedure.

Abstract: This chapter looks into the technical features of state-of-the-art wireless sensors networks for environmental monitoring. Technology advances in low-power and wireless devices have made the deployment of those networks more and more affordable. In addition, wireless sensor networks have become more flexible and adaptable to a wide range of situations. Hence, a framework for their correct implementation will be provided. Then, one specific application about real-time environmental monitoring in support of a model-based predictive control system installed in a metro station will be described. In these applications, filtering, resampling, and post-processing functions must be developed, in order to convert raw data into a dataset arranged in the right format, so that it can inform the algorithms of the control system about the current state of the domain under control. Finally, the whole architecture of the model-based predictive control and its final performances will be reported.

Abstract: The objective of this work is to set up a method to control the thermal behavior of existing buildings, by means of the model based predictive control approach. In the past years, several works about the predictive control problem for buildings have been produced in literature, but so far a method that describes how to approach this problem and how to optimize its control parameters has not been defined, yet. This work suggests a method supporting the customization of a model based predictive control system, in order to optimize its performance according to the real characteristics of the building. Also, the method suggests how to fine-tune control parameters according to the control policy (e.g. maximization of comfort or energy saving). The proposed method has been validated on a real case study, proving its effectiveness even in the presence of limited accuracy of the reduced model of the building. As for the selected case study, assuming a 50% error on the model, we proved that, thanks to the use of this method, the energy saving increases 8% as compared to the PID control, while thermal comfort increases by 33%.

Abstract: An energy audit is a standard process to support the decision-making in the area of energy management, aiming to improve buildings performance. Nevertheless, an energy auditor does not succeed as easily and quickly in identifying all the energy streams in a facility in order to decide whether retrofitting the audited object is beneficial. In fact, energy auditing of buildings is usually a time consuming and expensive process, due to efforts required for data collection and modelling of audited objects. However, the modelling phase might be made less demanding, thanks to the development of reduced models, conceived in the form of lumped parameters models. According to relevant literature, the detailed physical models are time consuming and often quite expensive; they are adopted when a very detailed evaluation is necessary. On the contrary, reduced-order models, also called grey-box models, showed their reliability to achieve a suitable description of the thermal response of buildings. The thermal parameters of the simplified models are usually extracted in real time; this allows estimating the thermal response of a building in its current state, whose information can be reused to make predictions about its expected behaviour. This paper attempts to derive a quick and efficient modelling procedure by identifying the unknown properties of a mathematical model based on partial observations of the heat dynamics of the building, that is, in our case, a small data collection of temperature measurements. Starting from a preliminary test performed in the machine laboratory of our department at the Università Politecnica delle Marche, the investigated empirical procedure for deriving grey-box models will be provided and the results will be analysed. The potential for energy retrofitting will be evaluated in order to define future developments.

Autore/i: PRINCIPI, Paolo; FIORETTI, ROBERTO; CARBONARI, Alessandro; LEMMA, Massimo
Classificazione: 1 Contributo su Rivista
Abstract: Non-residential buildings like healthcare ones contribute to energy consumption and cause a negative environmental impact. This is mainly due to the age of the buildings, their poor level of energy efficiency and the implementation of only a basic maintenance plan. Owing to the very limited budget available for public administrators, Energy Performance Contracting (EPC), that entails the involvement of an Energy Service Company (ESCo), can provide the entire or part of the capital needed for investments aimed at progressively increasing energy efficiency over their service life. In this paper, three acute hospitals and two community clinics built in Italy are analysed, in order to assess the economic feasibility of several energy renovation actions that can be included within EPC contracts. To this purpose, the outcomes of energy audits carried out in 2014 about these buildings are reported, which involved analyses of consumption measured over the previous three years and assessment of use profiles for the development of models to break down the overall consumption and to estimate potential savings. Diverse improvement strategies were assessed, consisting in either isolated or combined renovation actions and tested on the five buildings, whose comparison was carried out in terms of energy saving, pollution reduction and economic feasibility. As a result, the best combined renovation actions per each hospital were recommended, that included - but were not limited to - the improvement of the control and regulation of existing sub-systems without replacement, partial replacement of other sub-systems and integration of renewables. Finally, each scenario was evaluated through the payback period and other economic performance indexes in order-to assess the feasibility of the EPC framework when applied to this case study.

Abstract: Public administrations are encouraged to adopt actions for energy requalification of public buildings, which are responsible for considerable amounts of energy consumption. Low-cost technology improvements for energy renovation with high return on investment is a good opportunity when resource shortage hampers the adoption of expensive refurbishment. To this purpose, the integration of advanced control policies may optimize energy use of buildings with minimum hardware enhancement. In this contribution, we evaluated the performances of a control system based on fuzzy logic, supervising local Proportional-IntegrativeDerivative (PID) controllers, through numerical simulation. First, the design process will be described, with particular concern to the proper selection of the rules in the knowledge base and the design of the inference engine. Then, its performances will be compared with the ones provided by the use of just ordinary PID control units. The fuzzy based control system was simulated as an addiction to the heating system of an existing small public building, that is the “San Elpidio a Mare” community clinic located in Italy. The performances were assessed by means of simulations of an energy dynamic model developed in the DymolaTM environment, that had been previously validated with real consumption measurements. In this paper we will show not only what energy saving can be obtained by means of the fuzzy supervisor, but also its satisfactory performances in terms of stability of the control outputs.

Classificazione: 2 Contributo in Volume
Abstract: In this chapter we will present the basics of evaporative cooling walls. Water evaporative cooling systems exploit the latent heat of evaporation of water to reduce sensible heat of air, and therefore its temperature. Based on this principle, both direct and indirect approaches can be developed. Their adoptionmay dramatically decrease (and sometimes even cancel) cooling loads in warm and hot seasons. So these walls are the best candidates for adoption inmild climates with relatively long summer seasons,where the use of highly insulatedwalls to limit heating loads may cause internal overheating in hot periods and make the indoors quite uncomfortable and unhealthy. Not only can this technology considerably decrease incoming cooling loads, which is beneficial during warm and hot seasons, but it also keeps high insulation standards against heat dispersion in winter. More specifically, evaporative cooling walls represent an example of a hybrid solution deriving from the combination of ventilated fac¸ades and water evaporative cavity walls. In this chapter we will look into this technology, starting with an overview of the state of the art, then going through the basics of evaporative cooling systems and, finally, focusing on the issue of evaporative cooling walls. In particular, Section 8.4 will be devoted to highlighting some important concepts that are useful for their design, and will describe the experience gained by the authors while working in this field. Likely future trends, suggested sources of information, and conclusions will end the chapter.

This is mainly due to the age of the buildings, a poor level of energy efficiency and a basic maintenance plan. Owing to the very limited money available for public administrators, Energy Performance Contracting (EPC), involving an Energy Service Company (ESCo), can provide the capital needed for investments aimed at increasing energy efficiency. In this paper three acute hospitals and two community clinics in Italy are analyzed prior to EPC development in order to assess the economic feasibility of retrofit strategies. The outcome of energy audits carried out in 2014, the analyses of consumption measured over the last 3 years, and the assessment of use profiles were all considered for the development of models to break down the overall consumption and to assess potential savings. Recommended improvement strategies include better insulation in envelopes, enhancement of mechanical and lighting equipment, use of renewable energy, better regulation of systems. Finally, payback periods for the most likely scenarios were evaluated.

Abstract: Optimal energy management of underground transportation systems is widely recognized as a key aspect for significant energy savings at regional level. The three-year long EU funded “Seam4us” research project (2011 to 2014) aims to create a system for optimized integrated energy management, relying on the Passeig de Gracia metro station in Barcelona as the pilot station. One of the outcomes of the project was the installation of a wireless sensor network, in order to track in real time both environmental and energy parameters. The data collected by the network have been exploited to inform an intelligent control system about the state of the station. In fact, a reliable real-time sensing is critical for implementing advanced control policies in any kind of environment. For that reason, this paper will report on the Seam4us findings regarding real-time sensing of that quite harsh domain. The design criteria and constraints that led to the final installation will be argued. Then, post-processing functions, i.e. those algorithms turning raw data into the variables which can be processed by the controller, will be described. Finally, the general performance of the system will be discussed, in terms of reliability of data exchange and energy efficiency.

Abstract: As public buildings are responsible for considerable amounts of fuel consumption, public administrations are encouraged to adopt interventions for energy requalification of their real estates. In particular, low-cost energy requalification with high return on investments is a good opportunity when resource shortage hampers the adoption of expensive refurbishment. However, in order to properly plan such a process, a detailed energy audit must be carried out. In addition, a reliable model of the audited building is needed to breakdown the whole energy consumption and to simulate prospective energy savings from candidate requalification strategies. To that purpose, this paper will describe a new-generation Dymola based simulation approach, that is reliable enough for assessing the dynamic behaviour of public buildings, even when non-standard systems and heat transfer phenomena are involved. This model provides users with two main advantages: on one hand it facilitates the simulation of interacting physical phenomena (e.g. fluid-dynamics, thermal exchange etc...), on the other hand it allows to simulate even advanced control of existing HVAC systems. This last feature is not typical of standard energy simulation software programs. In addition, it is needed when we deal with low-cost energy requalification, because it is usually aimed at the enhancement of existing regulation devices, so that their behaviour must be simulated in order to find out the best customized control policy. Finally, the paper will assess energy savings which can be obtained through the improvement of the HVAC system's control policy for a case study relative to a small public building, that is used as a community clinic.

Abstract: Buildings energy audits ask for a thorough analysis of the audit object. According to the series EN 16247, all the factors affecting actual energy consumption must be assessed and estimated. One of the hardest contributions to be quantified at this stage is air change rates of buildings, particularly when no mechanical air supply system is installed. In this case, just air leakages through the external envelope and users behavior (e.g. opening of doors and windows) will determine the actual figures of air change rates. As a consequence, no direct measurement can be made. Among the indirect measurement approaches, the procedure using the decay of indoor carbon dioxide concentration provided good results, as described in literature. However, a number of disturbing factors must be considered, because they affect the transient behavior of air exchange between indoor and outdoor. As a consequence, the experimental setup that must be used should be made up of a kit of sensors, and the concentration decay must be evaluated with respect to the actual behavior of related parameters, such as outdoor air pressure and wind speed. This paper will provide more insights into the possibility of developing a testing kit for the energy auditor, so that she/he can evaluate air change rates of buildings through quick on-site surveys in the audited object, and then use the information thus collected as an input for the energy audit process. Such a challenge requires the development of a quite cheap, easy to install and low invasive monitoring kit, which is based on state-of-the-art wireless and low power monitoring technology. In addition, data analyses must be quick and partially automated. Finally, a preliminary test performed in a room of the Engineering Faculty at the Università Politecnica delle Marche in Ancona (Italy) will be reported.

Autore/i: C. Di Perna; A. Carbonari; R. Ansuini; M. Casals
Classificazione: 1 Contributo su Rivista
Abstract: The EU-funded project called SEAM4US (Sustainable Energy mAnageMent for Underground Stations) is targeted to define advanced control systems for cost-effective management of subway stations, which will be applied to the pilot "Passeig de Gracia" station of the metro network in Barcelona (Spain). To this aim, the environmental conditions of the station must be monitored in real-time. In particular, this paper focuses on the challenge of air flows estimation because this is one of the most critical yet tough variables to be monitored: expensive and intrusive measurement methodologies cannot be used extensively. So a novel methodology, based on the use of ordinary measurement probes and analytical methods and capable of identifying in real-time the intensity and dynamics of ventilation that is taking place, will be suggested. The information deriving from real-time measurements and analyses will be used to dynamically adjust the mechanical ventilation burden, that is currently relying on the station's air supply system, thanks to the adoption of intelligent control systems. Our study is based on both a measurement survey carried out in the aforementioned station and numeric analyses.

Development of an Expert Model to Assess Falls from Height Hazards in Construction Sites
JOURNAL OF CIVIL ENGINEERING AND ARCHITECTURE
Autore/i: Carlo Argiolas; Alessandro Carbonari; Emanuela Quaquero
Classificazione: 1 Contributo su Rivista
Abstract: This paper reports on the current state of an ongoing research project which is aimed at implementing intelligent models for hardly predictable hazard scenarios identification in construction sites. As any programmatic actions cannot deal with the unpredictable nature of many risk dynamics, an attempt to improve the current approach for safety management in the construction industry will be presented in this paper. To this aim, the features offered by Bayesian networks have been exploited. The present research has led to the definition of a probabilistic model using elicitation techniques from subjective knowledge. This model, which might be meant as a reliable knowledge map about accident dynamics, showed that a relevant part of occurrences fall in the “hardly predictable hazards” category, which cannot be warded off by programmatic safety measures. Hence, more effort turned out to be needed in order to manage those hardly predictable hazardous scenarios. Consequently, further developments of this research project will focus on a real time monitoring system for the identification of unpredictable hazardous events in construction.

Autore/i: Berardo Naticchia; Massimo Vaccarini; Alessandro Carbonari
Classificazione: 1 Contributo su Rivista
Abstract: This paper surveys the feasibility of an infrastructureless real-time monitoring system to provide prompt support for inspectors in charge of health and safety management on construction sites. The system was tested in the specific application of monitoring interference between teams working on large construction sites. The system accounts for a wireless and untethered tracking technology and a local server running a software tool for handling collected data, real-time site state visualization and remote interaction with safety inspectors. The low-level tracking technology is a ZigBee-based easily deployable and reconfigurable technology. In this paper the system is found to be able to cover large fields while keeping its non-invasive features, thanks to the implementation of a novel low-power approach. This paper shows the degree of support inspectors can get from the system: it is able to alert in the occurrence of interference and to log any unexpected behavior.

Autore/i: Giretti A.; Carbonari A.; Vaccarini M.
Classificazione: 1 Contributo su Rivista
Abstract: Purpose Embedded sensors coupled with intelligent control logics may be able to provide adaptive control of conditioning systems in buildings. Current building systems are inefficient in their energy usage in maintaining occupant comfort because they operate according to fixed schedules and maximum design occupancy assumptions1 . In this paper we present first models of ventilation systems in subways, targeted at estimating the savings attainable from the application of an intelligent adaptive control and to design an object-based model. This model will be implemented to control in real-time the operation of the ventilation systems. The models referred to are those of the test-case of Passeig de Gracia (PdG) subway station in Barcelona. Method This research is part of a EU FP7 currently funded project, entitled SEAM4US2 , aimed at defining a technological and methodological framework for optimized energy management in public underground spaces and at developing a fully featured pilot system for the dynamic control of the energy performances in PdG subway station in Barcelona. This paper deals with specifically energy savings from adaptive predictive control of fans and investigates how models can be developed. This particular station is served by axial fans with a ducted outlet3 . Performances were simulated through a Response Factors Method software programme. Adaptive and predictive control was designed, relaying predictions of user behavior in the station and receiving real-time context data from pervasive monitoring and actuator networks. Energy savings derived from the use of such an adaptive control were estimated, and a first lumped parameters model for the implementation of the predictive and adaptive control was developed in the DymolaTM environment. Results & Discussion We found that replacing the old-fashioned fixed schedule ventilation with the new adaptive approach, conditioning may be differentiated according to space and time. Theory suggests this may result in non-traction energy savings well above 10%.

Classificazione: 1 Contributo su Rivista
Abstract: Purpose One of the main concerns regarding integrated water resources management is related to the development of scalable monitoring and control systems for pro-active maintenance of water distribution networks. It is necessary for the availability of ultra-pervasive sensor-actuator networks to be deployed at the district level. The same technology is useful for several other applications involving sensors accrued from city to building scale. This paper deals with the design, development, and initial experiments of a first prototype of ultra-pervasive monitoring network for automated leakage detection in water distributions system (WDS). These pose technology challenges mainly generated by the need to transmit from underground. Method The availability of a new generation of ultra-pervasive communication and monitor-ing systems is a prerequisite for providing fine-grained, real-time monitoring data at district level, so that control policies can be applied in real-time. The sensing layer developed in the system object of this paper is intended for a dense de-ployment even underground. It is based on short-range battery-operated wireless networks, forming a mesh made up of end devices (sensors/actuators), routers/repeaters and coordinators/gateways. The coordinators/gateways –besides coordinating the network routing– transfer sensors packets to a host application enabling interconnection to fixed and mobile networks made available by the Telco operator. Because of this set-up the network can cover a large territory at low cost. It supports leakage detection algorithms, estimates leakage occurrence probability and pinpoints them. Results & Discussion First laboratory trials and preliminary onsite experiments show the feasibility of the approach and the potential for ultrapervasive communication through the network. Results indicate this system to be cheap and easily deployable alongside WDS.

A Bayesian model for real-time safety management in construction sites

Autore/i: C. Argiolas; A. Carbonari; F. Melis; E. Quaquero
Classificazione: 1 Contributo su Rivista
Abstract: Purpose This article reports on an ongoing research project, which is aimed at implementing advanced probabilistic models for real-time identification of hazardous events at construction sites. The model has intelligent capabilities for near real-time automated recognition of hazardous events during the execution phase. To achieve this, features of Bayesian Networks have been exploited. In addition, inputs to the model are assumed to be provided by a pervasive monitoring system deployed on the site. The need for this kind of intelligent tool is determined by the complexity inherent in construction sites, due to a variety of reasons, such as heterogeneity of the actors, the simultaneous nature of operations, harsh contextual conditions, and the only partially efficient current approach based on health and safety plans. Hence, this model is proposed as a support tool for health and safety coordinators for supervision of sites as they cannot guarantee a continuous physical presence. Method Given that there are no long-time series on past occurrences of hazardous events in all the potential contextual combinations presently available, the probabilistic models cannot be learned just through datasets. For that reason, the available data have been integrated with expert opinions. In particular, the conditional probabilities of the Bayesian networks are estimated by an elicitation process of subjective knowledge from the opinions of experts. The complexity of the phenomena under analysis are modelled as a tree structure with several levels (corresponding to the work-breakdown structure hierarchy), which itself is based on the top-down technique; it provides therefore a clear view of the global picture. The built-hierarchical tree allows the expert to weigh more easily causal relationships involved and also to define the qualitative structure of the net. Furthermore, the article describes and tests how conditional probabilities of the variables in the networks can be estimated, through gathering and interviewing groups of stakeholders and experts. Results & Discussion Our research has led to the definition of a probabilistic model using elicitation techniques for subjective knowledge. Furthermore, the development of such a model is part of a wider system relying on the implementation of a real-time monitoring network.

Autore/i: Giretti A.; Carbonari A.; Novembri G.; Robuffo F.
Classificazione: 1 Contributo su Rivista
Abstract: Purpose This paper reports on the development of intelligent probabilistic models for real-time estimation of construc-tion progress, which operate on the basis of a continuous data flow collected by monitoring networks deployed on-site. Several authors listed the advantages that would be provided by the availability of such models, like project performance and quality control, timely onsite inspections, better control of health and safety prescriptions against job injuries and fatalities. The findings reported in this paper represent a feasibility study and preliminary examples of Bayesian Net-works, which are able to infer the work progress attained at every step, starting from real-time tracks of the construction site activities. Activity tracks are represented as a set of state variables figuring out workers’ effort, equipment and mate-rials usage rates and other knowledge about the context. Method As estimations are always related to dynamic pro-cesses, Dynamic Object Oriented Bayesian Networks have been used to develop a set of first order Hidden Markov Models. Hence, the models are arranged as a sequence of time steps, where each time step propagates evidences collected by the site monitoring sensor network along the time line. The actual cumulative progress is computed as a function of the progress achieved in each time step. Models representing a number of typical tasks (external piping, on-site cast of reinforced concrete floor slab, walls erection, ceiling installation) for a real case of a construction site have been developed. Their structure has been designed as part of a general monitoring framework, covering all the phases from design to execution, where BIM design, monitoring systems, methodological process innovations, intelligent infer-ences and advanced visualization are combined. Results & Discussion The networks have been developed and vali-dated through data collected from a real case, and they have been shown to be able to infer work progress, the accuracy of which depends on the resolution and quality of the collected data.

Abstract: Bayesian networks are a very general and powerful tool that can be used for a large number of problems involving uncertainty: reasoning, learning, planning and perception. They provide a language that supports efficient algorithms for the automatic construction of expert systems in several different contexts. The range of applications of Bayesian networks currently extends over almost all fields including engineering, biology and medicine, information and communication technologies and finance. This book is a collection of original contributions to the methodology and applications of Bayesian networks. It contains recent developments in the field and illustrates, on a sample of applications, the power of Bayesian networks in dealing the modeling of complex systems. Readers that are not familiar with this tool, but have some technical background, will find in this book all necessary theoretical and practical information on how to use and implement Bayesian networks in their own work. There is no doubt that this book constitutes a valuable resource for engineers, researchers, students and all those who are interested in discovering and experiencing the potential of this major tool of the century.

Classificazione: 1 Contributo su Rivista
Abstract: High summer conditioning consumption is becoming a tough and critical issue and consequently there is a need to provide buildings with new technologies for energy saving. Current European and Italian legislation is also working in this direction. We present a preliminary experimental evaluation of the energy performance of a new technology which is capable of canceling conduction gains through walls: “water-evaporative walls”, which are not only able to prevent the entrance of energy fluxes from the exterior to the interior, but also to reduce wall temperatures to below the values found indoors. This solution basically suggests equipping standard ventilated façades with a proper water-evaporative system, which exploits the latent heat of water evaporation, in order to absorb summer cooling loads. From the technological point of view, it requires the insertion of a water spraying system and a proper insulating layer in the ventilated air chamber. The insulation will act not only as a standard insulating material, but also as a porous surface to store water sprayed by the system and then gradually release it when needed for cooling. The experimental analyses showed the effectiveness of this technology, which decreases the overall summer energy load in buildings by canceling conduction loads.

The first functionality consists in real‐time position‐tracking of workers involved on construction sites and the second ‐ in a software tool for the prevention of non‐authorized access to dangerous zones. This research step is part of a vaster, ongoing research project, addressing the development of a new generation of advanced construction management systems which allow real‐time monitoring and coordination of tasks, automatic health and safety management, on‐site delivery of technical information and the capture of “as‐built” documentation. This paper focuses mainly on the development of a reliable methodology for real‐time monitoring of the position of both workers and equipment in outdoor construction sites by applying Ultra Wide Band (UWB) based technologies. This positioning system was then interfaced with a software tool which performs virtual fencing of pre‐selected, dangerous areas. Guidelines for the design of the receivers’ topology will be addressed and the results of measurements recorded on a typical medium‐sized block of flats, during different phases of the construction progress will be summed up. Finally, the preliminary experimental results obtained by the virtual fencing application tool will be presented and used to plan future research objectives.
