Abstract: The impact of the users’ behavior on the building performance is largely recognized, especially considering most of common building operation and management (O&M) tasks. Predictions of human-building interactions are essential to improve building efficiency by decreasing wastes and costs connected to O&M while satisfying the comfort level required by the occupants. At this regard, building technological systems, which status depends on the users’ movement inside the buildings, like elevators, represent one of the critical spots, especially in high-density buildings. According to a “user-centered” approach, this paper moves toward the assessment of behavioral drivers which can influence the use of elevators in public buildings to define a probability use model useful to set specific maintenance policies. In situ evaluations are performed in a university building, where flows of people are highly dependent on the indoor activities scheduled, as lessons. A multinomial logit model for the probability of elevators’ use is built depending on factors such as: floors number, movement in group, direction (upwards, downwards). Users’ fruition patterns in the university building are detected using eye-tracking techniques and questionnaires. Results show how the elevators’ use probability increases when the number of floors to cross increases, also because of perceived movement comfort, while individuals’ attention is mainly affected by posters and signage systems placed along the way. The model could be implemented in building simulation models, to predict the elevators use during the time under different circumstances, hence to optimize related O&M measures.

Abstract: Among water-based mitigation strategies against urban overheating, dry mist systems are especially promising, given their local impact, cost-effectiveness and controllability. Intense cooling capacity has been reported under a variety of climates, however, there is a growing need to define specific design guidelines towards an informed and optimized use of the technology. Parametric analysis on validated models would assist in determining type and degree of correlation between key parameters, as well as magnitude and predictability of the cooling capacity. In this paper, for the first time, a 3D microclimatic model in ENVI-met is used to simulate a misting system installed in Rome, Italy, with high prediction accuracy for the air temperature (R2≃0.87, RMSE≃0.84 °C). The calibrated ENVI-met model is used then to perform parameterizations on the water mist system, focused on the role of three key design variables: i) water flow rate, ii) injection height and iii) local wind speed. Results show that the most significant thermal drops tend to occur close but out of the misted perimeter following the wind direction, with cooling effects further stretched for tens of meters. The cooling capacity increases with the total water flow rate (+0.2 °C per 10 l/h increment) and in presence of calm air (+35–40% per 0.8 m/s deceleration). Lower injections intensify the cooling a pedestrian height, which could be especially beneficial under windy conditions. Further research would target climate dependencies to extend the applicability of the above results and build up cohesive guidelines at the hands of urban planners and practitioners.

Autore/i: Maracchini, G.; Di Giuseppe, E.
Classificazione: 1 Contributo su Rivista
Abstract: The recently revised European standard EN 1745 describes methods for the determination of the thermal conductivity of solid masonry units, mortars, masonry units with formed voids and “composite” masonry units, i.e. masonry unit incorporating additional material in the voids, such as thermal insulation. The determination of the “dry” and “design” thermal conductivity values can be defined based on tabulated data, measurements, calculations or a combination of these. The main novelty of the new version lies in the inclusion of a method for the determination of the thermal design values of composite masonry elements. More details in this article.

SUSTAINABILITY
Autore/i: Baldoni, Edoardo; Coderoni, Silvia; Di Giuseppe, Elisa; D’Orazio, Marco; Esposti, Roberto; Maracchini, Gianluca
Classificazione: 1 Contributo su Rivista
Abstract: This article presents a novel software tool for the assessments of life-cycle environmental impacts and costs, which is aimed to support decision-making in the design phase of retrofit interventions in the building sector. By combining Life Cycle Costing (LCC) and Life Cycle Assessment (LCA) calculations and functionalities, this tool allows evaluating the long-term trade-offs between economic and environmental performance of investment projects in energy efficiency for buildings, while accounting for uncertainties in input parameters and economic scenarios. A major novelty of the software tool is the stochastic nature of both the LCC and LCA dimensions. The LCA is implemented with Monte-Carlo methods, while the LCC accounts for the probabilistic interdependence of macroeconomic variables over time. The software also includes advanced specific tools for parametrization and sensitivity analysis. Exemplary applications are presented in order to illustrate the novelty and the functionalities of the software tool.

From cost-optimal to nearly Zero Energy Buildings’ renovation: Life Cycle Cost comparisons under alternative macroeconomic scenarios
JOURNAL OF CLEANER PRODUCTION
Autore/i: Baldoni, E.; Coderoni, S.; D'Orazio, M.; Di Giuseppe, E.; Esposti, R.
Classificazione: 1 Contributo su Rivista
Abstract: Policies and financial framework aiming to encourage energy efficient building renovations should contribute to “fill” the existing investment gap between Cost-Optimal (CO) solutions, that are more economically convenient, and nearly Zero Energy (nZE) solutions, which have the lower energy consumption, in order to make more convenient to the investors to choose the more energy efficient options. This investment gap depends on the long-term expected value and volatility of several interdependent macroeconomic variables. However, standardized LCC methods used for CO assessments disregard the long-term uncertainty and interdependence affecting these variables and, consequently, misrepresent the impact of the associated risk on the economic convenience. The present work aims to model alternative macro-economic scenarios where to carry out a “stochastic” LCC of predetermined building renovation solutions, in order to provide a useful and effective decision tool for building LCC, and especially to evaluate whether and how much the future macro-economic scenario could influence the investment gap between a CO and a nZE refurbishment solution. At this aim, we estimated the Vector AutoRegressive (VAR) models of four alternative macro-economic scenarios, ranging from a “regular growth” case to more extreme conditions as experienced by major western economies in the last decades, based on real data, i.e. observed time series. The scenarios modelling and its relation to the stochastic LCC is the main result and novelty of the work compared to the conventional approach adopted in most of the literature and suggested by international regulations and standards. The method is illustrated through a case study, which demonstrates the potential of the developed methodology in providing interesting and informative results on the nature of the investment gap between CO and nZE solutions, that the policy should contribute to fill in order to address the environmental challenge in the building sector, and on how much this gap may vary depending on the volatility of the macro-economic context. The novelty of the work mainly lies on the possibility to highlight in which specific macroeconomic conditions the convenience of taking an investment decision under risk-aversion may be jeopardised (augmented), thus requiring a stronger (weaker) compensating public support.

Hydropower Generation Through Pump as Turbine: Experimental Study and Potential Application to Small-Scale WDN
WATER
Autore/i: Postacchini, Matteo; Darvini, Giovanna; Finizio, Fiorenza; Pelagalli, Leonardo; Soldini, Luciano; Di Giuseppe, Elisa
Classificazione: 1 Contributo su Rivista
Abstract: Pump-As-Turbine (PAT) technology is a smart solution to produce energy in a sustainable way at small scale, e.g., through its exploitation in classical Water Distribution Networks (WDNs). PAT application may actually represent a suitable solution to obtain both pressure regulation and electrical energy production. This technology enables one to significantly reduce both design and maintenance costs if compared to traditional turbine applications. In this work, the potential hydropower generation was evaluated through laboratory tests focused on the characterization of a pump working in reverse mode, i.e., as a PAT. Both hydrodynamic (pressure and discharge) and mechanical (rotational speed and torque) conditions were varied during the tests, with the aim to identify the most efficient PAT configurations and provide useful hints for possible real-world applications. The experimental findings confirm the good performances of the PAT system, especially when rotational speed and water demand are, respectively, larger than 850 rpm and 8 L/s, thus leading to efficiencies greater than 50%. Such findings were applied to a small municipality, where daily distribution of pressure and discharge were recorded upstream of the local WDN, where a Pressure Reducing Valve (PRV) is installed. Under the hypothesis of PRV replacement with the tested PAT, three different scenarios were studied, based on the mean recorded water demand and each characterized by specific values of PAT rotational speed. The best performances were observed for the largest tested speeds (1050 and 1250 rpm), which lead to pressure drops smaller than those actually due to the PRV, thus guaranteeing the minimum pressure for users, but also to mechanical powers smaller than 100 W. When a larger mean water demand is assumed, much better performances are reached, especially for large speeds (1250 rpm) that lead to mechanical powers larger than 1 kW combined to head drops a bit larger than those observed using the PRV. A suitable design is thus fundamental for the real-world PAT application.

Abstract: According to the challenge of global warming, trees play an effective role in reducing heat islands and improving thermal comfort. In this study, the impact of urban greening on microclimate and pedestrian comfort is studied using ENVI met v4 for a residential district in Tabriz, Iran. In-situ measurements of air temperature and relative humidity have been preliminary performed on ten points in the studied site and collected data used to successfully validate the model. Four scenarios with different trees species and patterns were simulated during typical summer and winter days, to assess benefits and disadvantages during different seasons, in terms of air temperature (Ta) and relative humidity (RH), mean radiant temperature (Tmrt) and physiologically equivalent temperature (PET). Result showed that the best scenario provides great summer cooling without compromising winter comfort. In summer Ta and Tmrt are decreased by respectively 0.29 °C and 20.04 °C; while in winter, they reach respectively 6.92 °C and 13.22 °C, compared the reference scenario characterised by 6.28 °C (Ta) and 23.47 °C (Tmrt). These results in a summer PET improvement from 34.92 °C to 26.16 °C, thus moving from an original hot thermal sensation to a slightly warm one. Based on the outcomes of the study, it is possible to provide useful design recommendation for urban adaptation plans.

Classificazione: 1 Contributo su Rivista
Abstract: Internal insulation is a typical renovation solution in historic buildings with valuable façades. However, it entails moisture-related risks, which affect the durability and life-cycle environmental performance. In this context, the EU project RIBuild developed a risk assessment method for both hygrothermal and life-cycle performance of internal insulation, to support decision-making. This paper presents the stochastic Life Cycle Assessment method developed, which couples the LCA model to a Monte-Carlo simulation, providing results expressed by probability distributions. It is applied to five insulation solutions, considering different uncertain input parameters and building heating scenarios. In addition, the influence of data variability and quality on the result is analyzed, by using input data from two sources: distributions derived from a generic Life Cycle Inventory database and “deterministic” data from Environmental Product Declarations. The outcomes highlight remarkable differences between the two datasets that lead to substantial variations on the systems performance ranking at the production stage. Looking at the life-cycle impact, the general trend of the output distributions is quite similar among simulation groups and insulation systems. Hence, while a ranking of the solutions based on a “deterministic” approach provides misleading information, the stochastic approach provides more realistic results in the context of decision-making.

Classificazione: 1 Contributo su Rivista
Abstract: As a consequence of Climate Change, during last 15 years the frequency and intensity of heatwaves increased in all EU. Many EU cities are already working on climate mitigation strategies, while renovation of existing buildings and design of new ones has a great urban adaptation potential against “heat” challenge. LIFE SUPERHERO aims to diffuse the use of the HEROTILE-based roof (“HBR”), a new building roof concept developed during a previous LIFE HEROTILE project, as a sustainable passive cooling technology by: (1) overcoming the existing legislative barriers; (2) demonstrating the impact of HBR use on occupants’ “green” behaviours; (3) providing a tool to assess HBR environmental and economic benefits. LIFE SUPERHERO promotes a synergy between climate adaptation and mitigation: the HBR allows to increase buildings thermal comfort (adaptation), while entailing a reduction of cooling energy and greenhouse gases(mitigation). To reach these goals a strong consortium has been set, including roof tiles Producers, Associations, Municipalities and Research centres working together to i) improve buildings environmental protocols considering HBR benefits; ii) monitor three buildings demonstrators where the impact of HBR on occupants’ behaviour will be shown; iii) entail the development of a free software for life cycle assessment, to facilitate the implementation of climate change adaptation strategies at local level.

Classificazione: 2 Contributo in Volume
Abstract: Exterior walls play a significant role in buildings thermal behaviour, and utilization of proper insulation materials with high thermal performance and low adverse environmental impacts is of great importance. The main aim of this study is to assess thermal and environmental benefits and drawbacks of honeycomb cardboard application in external wall configuration of prefabricated buildings. Its thermal conductivity was measured by guarded hot plate method, and its steady-state as well as periodic thermal transmittances were obtained. Furthermore, main construction junctions were simulated, and their linear thermal transmittance was studied. Secondly, with a life cycle assessment (LCA) approach, the adverse impacts of cardboard on environment in production phase and within a limited impact category set were studied. Additionally, the same procedures of thermal and environmental assessments were performed on a number of functionally equivalent insulation materials to be compared with cardboard. The results demonstrate an overall image of positive and negative consequences of cardboard application as insulation for wall envelopes.

Riflettanza “equivalente” di coperture in laterizio. Valutazione dei benefici sul raffrescamento degli edifici e sull'isola di calore urbana
Autore/i: D’Orazio, M.; DI GIUSEPPE, E.; Cozzolino, N.; Allen, R.; DI FUSCO, A.; D’Anna, G.
Editore: Laterservice Edizioni
Classificazione: 3 Libro
Abstract: Il D.M 26.06.2015 “Requisiti Minimi” impone al progettista di valutare l’efficacia, in termini di rapporto costi-benefici, di soluzioni tecnologiche per le coperture degli edifici, al fine di limitare i fabbisogni energetici per la climatizzazione estiva ed il surriscaldamento a scala urbana. Di fronte ad un’ampia varietà di tecnologie costruttive, il progettista rischia di trovarsi disorientato e di privilegiare la scelta di materiali per il manto ad elevata riflettenza solare piuttosto che valutare strategie alternative, sostenibili e durevoli che sfruttano la climatizzazione passiva, come la ventilazione; soluzioni entrambe indicate dal legislatore. Il presente manuale, risultato di una attività di ricerca condotta dall’ANDIL, dal DICEA dell’Università Politecnica delle Marche e dal BMI Technical Centre, presenta due metodi di calcolo complementari della “Riflettanza Equivalente” di coperture a falde, ottenibile grazie a diverse soluzioni progettuali, quali un corretto bilanciamento tra isolamento termico e massa inerziale, l’inserimento di membrane riflettenti sotto il manto e la presenza di uno strato di ventilazione/traspirazione sotto e attraverso le tegole. Tali metodi, e i valori di Riflettanza Equivalente ottenuti per diverse tipologie di copertura, possono essere utilizzati dal progettista come parte integrante e conforme alla valutazione richiesta nel D.M. Ministerial Decree 26.06.2015 "Minimum Requirements" requires the designer to evaluate how effective a roof construction will be in limiting summer cooling energy requirements and the Urban Heat Island effect. The legislation specifically mentions reflectivity as one option when promoting all passive cooling solutions. Therefore it would be easy for the designer, when faced with a wide variety of construction technologies, to believe that their only choice was materials with high Total Solar Reflectance rather than evaluating alternative sustainable and durable strategies. This manual, resulting from research activities by ANDIL, DICEA of the Università Politecnica delle Marche and BMI Technical Centre, presents two complementary calculation methods for the "Equivalent Reflectance" of roofs; highlighting the benefits provided by solutions such as: a correct balance between thermal insulation and inertial mass, using reflective membranes below the tiles and ventilation beneath and through the tiles. These methods, and the Equivalent Reflectance values obtained for different roof types, can be used by the designer as an integral and compliant part of the evaluation required in the legislation.

Classificazione: 1 Contributo su Rivista
Abstract: A remarkable advantage of clay tiles roof coverings in hot climates is the realization of a ventilated air layer between them and the roofing underlay that allows a natural and forced convection through the tiles joints and the channel from eaves to ridge, thus cooling the roof materials. However recently, in many countries, regulatory developments on buildings energy efficiency or buildings sustainability certification protocols are increasingly encouraging the use of alternative strategies, with the aim of reducing the urban heat island (UHI) effect and the buildings’ cooling consumptions. Among them, the use of ‘cool’ materials for roof covering. These mandatory or voluntary measures de facto push the construction products market towards specific directions, risking penalizing traditional components such as clay tiles. This article reports the results of experimental and numerical activities carried out in order to extensively characterize the optical properties of clay tile materials and investigate their impact, also coupled with above sheathing ventilation, on the thermal performance of a ventilated roof under warm-temperate climate. In the first phase of the research, the main optical properties of over 30 different clay products have been experimentally characterized in order to get a clear and extensive picture of such properties for the materials spread in the market. In a second phase, starting from the thermal data collected on an experimental real-scale building, a dynamic energy analysis tool was calibrated and used to perform simulations by varying the optical properties of the roof covering thus assessing the impact on the roof temperatures, also in comparison to a clay tiles roof. The results underline that the use of the above sheathing ventilation obtained through clay tiles is an effective strategy to reduce roof temperatures, even if covering materials are not qualified as ‘cool’, thus impacting on both UHI and indoor comfort.

Classificazione: 1 Contributo su Rivista
Abstract: An experimental study was conducted to improve the comfort and liveability of urban open spaces during the hottest months of the summer by implementing an overhead water mist cooling system. The campaign was conducted in two different Italian urbanscapes (Ancona and Rome, representative of Cfa and Csa climates) one after the other. Monitoring data and comfort questionnaires were combined to extract useful information by means of statistical tests, regressions and data mining algorithms and, ultimately, to delineate design and operating guidelines to maximize people's satisfaction with the misted environment. The cloud of droplets reduced the temperature and the UTCI by 8.2 °C and 7.9 °C respectively, against a 7% mean humidity premium. The vertical cooling and humidification profiles obeyed a Lorentzian distribution, peaking within approximately 0.5 m of the injection. The severe overheating experienced outside of the cooled areas evanished under the spray, with 67% (Ancona) to 90.6% (Rome) of respondents reporting only slight bending from thermal neutrality. Perception and preferences towards solar radiation, humidity level and wind all improved within the droplets mist. In terms of comfort-oriented, optimized design criteria, the system proved to work best with a dominant and steady light breeze (1–2 m/s), in highly irradiated sites and suspended at 1.2–1.5 m above the average height of users.

ENERGY POLICY

Classificazione: 1 Contributo su Rivista
Abstract: Energy saving is a major policy objective worldwide and in the EU in particular. Evaluating the convenience of energy-efficient investments, however, is complex. This paper aims to apply stochastic Life Cycle Costing to assess the economic value of energy-efficient building retrofitting investments. The proposed approach investigates how macroeconomic variables affect such an evaluation by explicitly taking into account their interdependent stochastic nature. Consequently, the economic evaluation of an investment is itself stochastic thus expressing both its expected value and its inherent uncertainty and risk. On this basis, an illustrative case-study is presented, where alternative designs of the energy-saving intervention are compared and a sensitivity analysis performed to identify the determinants of the LCC outcome and of its variability. In terms of policy implications, a tool providing a sounder evaluation of the convenience of such investments can suggest when and to what extent incentives may be appropriate to facilitate these investments and what possible financial instruments could be put forward in order to reduce the associated risk.

Autore/i: Di Giuseppe, Elisa
Classificazione: 1 Contributo su Rivista
Abstract: An important part of building design and renovation is the need to select solutions using multiple criteria, including energy savings and life cycle economic impact. The difficulty lies in evaluating a large number of possible design solutions and/or their combinations, as well as having to calculate their performance and costs. The work reported in this paper proposes an assessment tool combining energy simulation software with Visual Basic Application for parametric building simulation and life cycle cost calculation. It aims to provide designers with a useful way of comparing the affordability of energy efficiency measures with low computational costs. A probabilistic approach is also suggested for global cost calculation based on Monte Carlo methods. The tool is applied to an existing building for which several alternative retrofit solutions had been designed. The results demonstrated the effectiveness of the tool in providing realistic and useful results for designers and building owners.

Classificazione: 1 Contributo su Rivista
Abstract: In the light of the regulations on buildings energy performance, the designers face the need to choose among alternative design solutions, having to assess their effectiveness according to several -sometimes conflicting- points of view, such as the energy saving, the indoor comfort, the environmental and economic impact. This paper reports the results of the application of genetic algorithms to solve this “multi-objective optimization problem” in a building retrofit intervention in Italy. The results, even if related to a single case-study, suggest the optimal efficiency measures, whose robustness was tested in different Italian climatic zones.

Building Retrofit Measures and Design: A Probabilistic Approach for LCA
SUSTAINABILITY
Autore/i: Favi, C.; DI GIUSEPPE, E.; D’Orazio, M.; Rossi, M.; Germani, M.
Classificazione: 1 Contributo su Rivista
Abstract: Green building design and architecture have become widespread tenets in the development of sustainable buildings. In this context, the use of sustainable materials and the awareness of resource/energy consumption are strategic aspects to consider for the improvement of building performances. This paper presents a new and structured approach to address uncertainty and sensitivity analysis in Life Cycle Assessment (LCA) to support the decision-making process in building renovation. This "probabilistic" approach to LCA allows for the obtaining of results expressed as ranges of environmental impacts and for alternative solutions, offering an idea of the meaning of input parameters' uncertainties and their influence on the result. The approach includes (i) the assessment of inputs' uncertainties (represented by Probability Density Functions-PDF); (ii) the data sampling; and (iii) the uncertainty propagation (Monte Carlo method). Variance decomposition techniques have been used to sample inputs' PDFs and assess their impact on the LCA result distribution (sensitivity analysis). The methodology application is illustrated through a case study where three building retrofit measures were assessed. Results provide an insight about the uncertainties of LCA indicators in terms of climate change and nonrenewable energy. The input parameters related to the use phase are confirmed as the most influential in building LCA.

Abstract: LCC procedures are commonly used in building retrofit interventions for the evaluation of the costs and benefits of different solutions. LCC methods are also commonly applied to energy retrofit interventions according to UNI-EN 15459. However, these procedures can give significantly different results in relation to the methods used to define the economic and technical parameters used in the calculation. Several authors have highlighted how the uncertainties related to the quantification of the costs of initial investment and maintenance, the economic scenarios (inflation and interest rates), the costs of energy and labor and the "service life" of the components strongly influence the results and the assumption of different data sets can result in significantly different results. Several authors pointed out that it is necessary, prior to these procedures, to perform sensitivity analyzes, useful for understanding if and how each of these parameters can influence the results, which leads to the need to use probabilistic methods. The study reported here analyses the influence that different assumptions about the service life of building components have on the economic benefits brought by interventions of energy requalification. Specifically, through a specially developed probabilistic procedure, the influence on the global costs of different assumptions about the probability distributions and the specific parameters characterizing each of them related to the service life of components useful to realize the thermal insulation was evaluated. the envelope of existing buildings. In particular, four different probability distributions (normal, uniform, left triangular, right triangular), different values of the median have been taken into consideration for the same distribution amplitude and the global costs and the return time values have been evaluated. investment considering different alternative economic scenarios for inflation and interest rate.

Abstract: Thermal bridges play a significant role in the heat loss of nearly Zero Energy Buildings (nZEB). In the case of existing buildings, the underestimation of thermal bridges can lead to errors of about 20 % in the assessment of their energy requirements. Nowadays, proper simulation tools for evaluating the building energy performance in dynamic conditions are increasingly needed. Their outputs are important inputs for life cycle costs (LCC) and life cycle assessment (LCA) as well as for energy audits. A weak point is that the tools which are currently well established on the market, do not consider the contribution given by thermal bridges to the overall building energy balance as they rely on a onedimensional approach to recreate heat flows. Several scientific studies deal with different methods that can be applied to evaluate the dynamic behaviour of thermal bridges, but they disregard the wall capacity to accumulate/release heat loads and the role played by internal temperatures. This work analyses some numerical methods proposed by different authors based on the discretization of thermal bridges and their characterization in dynamic regime. A calculation procedure is evaluated to underline its potential as a rapid dynamic calculation algorithm to be integrated in the current software for dynamic analyses. The surface temperatures and the heat fluxes are taken into account. In the present work, the method of the equivalent thermal wall has been implemented to get the input parameters required to dynamically assess the thermal bridges energy contribution. Afterwards a finite volume analysis is developed to compare the outputs coming from different methods in terms of crossing fluxes, surface temperatures and thermal storage capacities. A low percentage error is found between the equivalent thermal wall and the real one in terms of surface temperatures. This achievement allows to carry out proper superficial condensation assessments. Anyway the above-exposed procedure is quite complex and time-consuming. The algorithm is then expected to be refined in the future by simplifying the necessary operations for the evaluation of thermal bridges.

Abstract: One of the major challenge facing the achievement of nZE standards in existing buildings is the economic issue: the evidence of monetary gains of energy savings facing high investment costs seems still rather limited to the investors’ eyes. In this context, LCC methods have gained much importance in recent years. However, they present a limitation due to the notable simplifications and hypothesis usually made for input parameters that may affect the results. In order to overcome this limit, this work suggests a probabilistic LCC based on uncertainty and sensitivity analysis via Monte Carlo methods and illustrates it through a building case study under several retrofit scenarios sighting the target nZE. The methodology allows investigating the economic effectiveness of alternative measures, giving insight into possible ranges of the economic indicator related to a specific design option. The analysis is focused on a micro-economic dimension and based on the availability and reliability of inputs data and on their proper characterization with Probability Density Functions. Variance-based methods for sensitivity analysis are employed to establish the most influential parameters on output uncertainty. The paper demonstrates the potentials of a probabilistic LCC in providing a more realistic decision support about investments for energy efficient projects.

Abstract: Life Cycle Cost (LCC) analysis in the field of building renovation is considered an important decision support of the design process in order to compare the effectiveness of different energy efficiency measures (EEMs). Nevertheless, data uncertainty is a well-recognised issue associated with LCC deterministic calculation methods and probabilistic methodologies could instead provide a more effective decision support. This paper proposes a Monte Carlo based methodology for uncertainty quantification that combines parametric building simulation and LCC analysis, showing a great potential in the possibility of combining several EEMs and undertake the uncertainty calculation with low computational costs and high accuracy of the result. The work aimed to identifying and quantifying the main uncertain inputs of the LCC assessment and developing a tools suite to automate the process of evaluation of the energy impact due to the combination of several EEMs and quantification of the uncertainty distribution of the output. Results from the application to a case study are mainly intended to illustrate the methodology application and underline the impact that input uncertainties may have on the output variable. The difficulty to identify the robust EEMs is particularly due to the great influence of macroeconomic parameters uncertainty used in the calculation.

Assessment of the effectiveness of cool and green roofs for the mitigation of the Heat Island effect and for the improvement of thermal comfort in Nearly Zero Energy Building
ARCHITECTURAL SCIENCE REVIEW

Classificazione: 1 Contributo su Rivista
Abstract: The effectiveness of cool and green roofs to improve thermal comfort could be strongly dependent on the U-value of the roof itself and on the way it has been constructed (ventilated or unventilated, lightweight or massive, etc.). Recent strict limits on the U-values of building envelopes run the risk of reducing the effectiveness of cooling strategies in roofs which could be employed in warm and temperate climates to reduce surface temperatures and consequently to cool internal environment. In this paper, we experimentally analyse some roof systems (a high-albedo membrane and a green roof) compared to traditional ones in a Nearly Zero Energy Building, in order to provide new information concerning their effect on the internal comfort and the air temperatures of the surrounding environment. Experimental results confirm that, while the effectiveness of green and cool roofs for the mitigation of the Urban Heat Island effect is well established, the use of high-albedo materials on roofing systems with very low U-value is of little effectiveness for internal comfort. The green roof is distinguished by its passive cooling ability due to the evapotranspiration phenomena of the vegetation and the storage capacity of the substrate.

Classificazione: 1 Contributo su Rivista
Abstract: In recent building practice, obligations of legislation relating to Nearly Zero Energy Buildings (NZEB) (European Directives 2002/91/EC and 2010/31/EU) are carried out mainly by high thermal resistance and total air tightness of the envelope, in order to minimize heat dispersions by conduction and infiltration as much as possible. These measures cause new ways of heat and moisture exchange in the building envelope and are likely to create high internal moisture load with consequences for durability of materials and inhabitants’ comfort and health. Improvement in the thermal performance of the envelope can then lead to the paradoxical need for high energy consumption in order to handle the vapor peaks indoors by using mechanical ventilation equipments. Even if with HVAC devices it is possible to provide an acceptable indoor climate, there is still a need to develop more passive and less energy intensive methods to moderate the indoor environment in NZEB. In recent decades many authors have focused on a promising strategy related to the use of “moisture buffering” materials which dampen indoor humidity variations without additional energy costs. Nevertheless, many internal finishing materials commonly used at present are still not highly performant or lead to problems of hysteresis. In the present study, we propose an alternative solution, which is the design of a moisture buffering “active” device, to be integrated in a part of the building envelope, which is able to measure the relative humidity indoors and control its loads by a low-energy-consumption fan system. The humidity control performance of the device has been dynamically tested in a climate chamber and has been compared with traditional “passive” material samples in order to measure the Moisture Buffering Value (MBV) according to the DTU test method. Experimental results showed that “passive” samples have high moisture buffering values [MBV = 6.12 g/(m2% RH)] and do not lead to hysteresis phenomena. The MBV measured in the “active” devices increased up to 29%, which predicts promising future applications for low-energy-consumption indoor humidity control.

Abstract: The presence of an air gap between a photovoltaic (PV) module and roof facilitates ventilation cooling under the device and consequently reduces cell temperature and improves its performance. In case of rack-mounted PV installation, the Nominal Operating Cell Temperature (NOCT) method could be effectively used to predict the temperature of the module for various environmental conditions. Many countries, for esthetic purposes, offer economic advantages (tax deductions, incentives, etc ... ) for the installation of building integrated photovoltaic modules (BIPV), with water-tightness capability and adequate mechanical resistance in order to substitute tile covering or part of it. Nevertheless, poor or absent ventilation under BIPV panels could cause them to overheat and reduce their efficiency. Lack of validated predictive tools for the evaluation of BIVP energy performance could be another barrier to their widespread application. In this study, we investigated the thermal performance of PV modules installed in a real scale experimental building over a traditional clay tile pitched roof in Italy for almost one year (from August 2009 to June 2010). One PV module was rack-mounted over the roof covering with a 0.2 m air gap; the others were fully integrated and installed at the same level of the roof covering (one with an air gap of 0.04 m, the other mounted directly in contact with the insulation). Temperature and heat flux measurements for each panel, and environmental parameters were recorded. Two temperature prediction models, NoCT model and SNL (Sandia National Laboratory) model were used to predict BIPV temperature and energy efficiency so that their suitability for BIPV could be evaluated. SNL model takes into account also the wind speed. Experimental results demonstrate that even though the rack-mounted PV module constantly maintains cell temperature below that of the other full-building integrated modules, due to the presence of a higher air gap, the difference in the energy produced by the BIPV modules estimated for the entire monitoring period is less than 4%. The two predictive models, NOCT and SNL, cause the differences in predicted and calculated temperature up to 10 degrees C. However, subsequent percentage variations on the energy predicted compared to that arising from the temperature measured generally turn out to be lower than 5%. An optimization of empirical coefficients used for calculations based on the SNL method allows for the reduction of this value below 2.5%.

Abstract: Many of the current European Member States regulations on energy saving in buildings seem to follow North European trends that call for high insulation of the envelope. However, this kind of set-up overlooks some specific elements that are necessary to build typical buildings in warmer climates. Thermal inertia on the internal surface of the envelope has traditionally been used in such contexts not only to contain solar gains but also to protect against cold winter because of its capacity to store and to slowly release energy. This research investigates how thermal inertia on roof slabs could positively affect the comfort indoors, also in buildings that tend towards being nearly zero-energy buildings, as suggested by last European Directive 2010/31/EU. With this aim, an experiment was conducted on a full-scale building with different roofs, on light and heavy slabs, under hot and moderate climatic conditions (Ancona, Italy). The thermal performance of roofs was monitored during summer and winter seasons. In winter, the building was also subjected to cyclical internal heat gains. The experiment demonstrated that a certain thermal inertia in the slab guarantees better indoor comfort in both summer and winter, and it can also reduce energy consumption from heating.
