The preservation of historic churches and their most precious artefacts usually includes a monitoring campaign of the indoor microclimate conditions. This research presents the information that can be obtained through the application of a novel set of risk indices to the monitored data acquired in a Baroque church of the 18th century in Italy. The main risks found with this comprehensive methodology, i.e. the biological risk that induces the growth of mould and the chemical and mechanical risks due to unsuitable indoor parameters, would not have been identifiable using the traditional approach based on the National UNI 10829 Standard. Indeed, such an approach only shows that indoor air temperature (below 15°C for 71% of the time) and relative humidity (over 85% for 73% of the time) are outside the range suggested for the conservation of the frescoes. On the other hand, the indications provided through risk indices can be used for more detailed information on the nature of the risks to assess, also in the case of a low-resolution monitoring campaign, so as to benefit the conservation of the widespread heritage inventory, for which funding is usually scarce.

Energy poverty is defined as the condition in which low-income people is no more able to face the costs of energy bills and consequently accept to live in cold and uncomfortable houses. In recent years the scientific literature about this specific issue has registered a significant growth, despite the problem is mainly approached from an econometric point of view to which instead medical, social and energy aspects have to be coupled. Recent EU policies like the Clean Energy Package and the Energy Building Performance Directive Recast III encourage to increase the efforts to tackle and eradicate the energy poverty. The paper approaches the problem focusing on one of its complementary causes: the building energy performance. The adopted methodology includes the calculation of the energy costs for each household, the definition of the energy poverty threshold, the calculation of the related building energy performance limit, otherwise leading to the energy poverty condition. These data, associated with the energy performance certificates, are used to create a GIS based mapping of the buildings potentially affected by energy poverty. Maps can be used to support decision making process in addressing appropriate strategies at urban level to tackle the energy poverty risk. The paper includes a case study in the city of Bologna where the proposed methodology is tested.

The renovation or the functional transformation of existing stock to meet the new comfort standards and energy demand reduction often requires comparing alternative technological options and designing solutions especially when it involves historical buildings where the main goal is usually to preserve the original image and value of the building. The paper reports a study regarding the potential covering of the inner courtyard of Palazzo Poggi in Bologna with a roof to create an intermediate new space between outdoors and indoors to be used all year long. The study is particularly focused on the definition of a simplified algorithm to predict and evaluate the annual temperature trend of the court, once it has been covered, assuming some geometrical and thermal characteristics of the roof. The paper describes the calculation algorithm and its application on the Palazzo Poggi case study where a covering in EFTE (ethylen-tetrafluorethylen) membrane is supposed to be created.

Coconut fibre insulators represent an insulating material considered as “exotic”, which clashes with the scepticism of his thermo-hygrometric behaviour, particularly in the case of covering technology such as green roofs, which is a technological solution often adopted in the case of sustainable buildings or nearly zero energy building. Green roofs represent a valid constructive solution with high thermal performances, adopted both in existing and new buildings. The purpose of the research regards the study of the thermo-hygrometric behaviour of the concrete (CLS) and Cross-Laminated Timber (CLT) slabs, insulated with coconut fibreboards (CF) such as an alternative of synthetic insulator, referred to 10 different green roofs scenarios. The results show that coconut fibre insulations are equally comparable to natural and synthetic materials, and the doubts for their applications, including the green roofs, are related to technological solutions for the implementation in the market and their diffusion between the buildings materials, rather than their hygrothermal features.

This study focuses on the application of coconut fibre insulators, an insulating material rarely utilized in the Mediterranean context. Despite its undoubted thermal performance, some queries are related with of his thermo-hygrometric behavior. More precisely, during the use of coconut for covering building for realizing green roofs, which represent a technological solution often adopted in the case of sustainable buildings or nearly zero energy building. Green roofs represent a valid constructive solution with high thermal performances, adopted in existing and new buildings. This paper investigates the thermo-hygrometric behavior of the concrete and Cross Laminated Timbre slabs, insulated with coconut fibreboards (CF) such as an alternative synthetic insulator, referred to a series of different green roofs scenarios. The results show that coconut fibre insulations are equally comparable to natural and synthetic materials. Therefore, coconut fibre could represent a good chance for realization of green roof having high thermal performance and hygrothermal behavior in the same time. This material could be an alternative solution to the normal synthetic materials actually used, in a perspective of sustainable architecture.

The evidences of the influence of climate change (CC) in most of the key sectors of human activities are frequently reported by the news and media with increasing concern. The building sector, and particularly energy use in the residential sector, represents a crucial field of investigation as demonstrated by specific scientific literature. The paper reports a study on building energy consumption and the related effect on indoor thermal comfort considering the impacts of the Intergovernmental Panel on Climate Change (IPCC) 2018 report about temperature increase projection. The research includes a case study in New York City, assuming three different scenarios. The outcomes evidence a decrease in energy demand for heating and an increase in energy demand for cooling, with a relevant shift due to the summer period temperature variations. The challenge of the last decades for sustainable design was to increase insulation for improving thermal behavior, highly reducing the energy demand during winter time, however, the projections over the next decades suggest that the summer regime will represent a future and major challenge in order to reduce overheating and ensure comfortable (or at least acceptable) living conditions inside buildings. The growing request of energy for cooling is generating increasing pressure on the supply system with peaks in the case of extreme events that lead to the grid collapse and to massive blackouts in several cities. This is usually tackled by strengthening the energy infrastructure, however, the users’ behavior and lifestyle will strongly influence the system capacity in stress conditions. This study focuses on the understanding of these phenomena and particularly on the relevance of the users’ perception of indoor comfort, assuming the IPCC projections as the basis for a future scenario.

This study focuses on the introduction of different types of insulation materials into existing building systems in Europe, where the chosen scenarios differ by climate zone and according to the Köppen climate classification. The insulation materials used are specifically: natural fibre materials, mineral fibre materials and artificial materials. The analysis in question was based on the assessment of the risk of interstitial condensation between the existing masonry and the insulation and the WCI [Kg/m2] (Water Content in the Insulation), through various simulations in dynamic mode, over a reference period of 10 years prior to the energy upgrading intervention. The case study buildings were taken from TABULA and divided by climatic zone, for the years of construction from 1945 to 1969 related to the building typology of single-family houses, wherein each building system the insulation was placed towards the warm side with a fixed thickness of 5 cm. The simulations concerned: a) the application scenario, b) the type of stratigraphy chosen, (c) exposure of the existing building system. The outputs generated by the simulations provided the data to determine in which type of building, depending on the insulating materials, interstitial condensation is formed or not. It was shown that only for the climate zones of the cities of Oslo and Brussels, associated with their own building typologies, for the insulating materials: mineral and natural, there is the formation of interstitial condensation.

The characteristics of the outdoor microclimate influence directly the outdoor thermal comfort that depends on surface reflectance, green albedo, trees, buildings, sky view factors, etc. Several researches and studies about outdoor microclimate examine area of cities, districts, squares, streets, parks, etc. and a proportion of this research studies is about the effect of outdoor microclimate on people thermal comfort, e.g. measure following Physiological Equivalent Temperature (PET). Thermal comfort in outdoor spaces has the crucial role of guaranteeing a comfortable staying in public places (such as squares, parks, etc.), as without thermal comfort people won't stay in such places. For this reason, research on tourism focuses more on outdoor thermal comfort than on indoor thermal comfort (e.g. in museum). Designing archaeological sites is very interesting and complex, since it's possible to study different scenarios and themes, together with strategies focused on solving and enhancing specific situations. Those, indeed, can vary: archaeological areas can be seen both as an exhibition area – focusing more on its relics and their correct preservation – or as an outdoor space – focusing more on the outdoor comfort, not just for the area itself but for the visitors too. In this paper we therefore report a thermal comfort and microclimate case study considering how the transformation of the urban area that surrounds an archaeological site could improve the outdoor comfort for tourists. This study uses the ENVI-met software to reproduce the actual area and six scenarios based on different urban modifications of said area: thermal variables such as air temperature, relative humidity, surface temperature and PET are considered to understand if said changes can have a positive or negative impact on thermal comfort for tourists. Comparing real and simulated data we get to focus on the scenarios with the most positive impact, in order to understand how the city could change to improve the presence of tourists in the area and what are the key elements to reach the outdoor comfort.

Environmental monitoring represents a key step for restaurateurs to follow who strive to ensure the preservation of buildings and artifacts while allowing for people’s thermal comfort. This paper describes the possibilities and main issues arising from the study of indoor microclimates. The presented case study focuses on the monitoring data analysis for two rooms of the Realm of Venaria Reale, in Turin. The adopted methodology provides for the gathering of knowledge about the history, the geometry, and the change of use in the course of the lifetime of the building. This information allows us to construct a virtual model of the building, through which it is possible to evaluate the past and present and to hypothesize future scenarios regarding the indoor environmental conditions. Moreover, this paper presents a specific index, namely the Heritage Microclimate Risk (HMR), which enables us to evaluate the risk level to which the artifacts kept within historic buildings are exposed. With that database of information, we can preemptively define which actions (managerial and structural) would need to be taken for the preservation of the artifacts and the building itself, avoiding the possible risk component taken by working on the real building.

Building envelope design is rising in relevance and, within this specific context, the application of passive and climate adaptive building shells (CABS) is investigated as an opportunity for energy savings and improvement of users’ thermal and visual comfort. The paper reports a research concerning the climatic based development of a customized dynamic façade based on a passive self-adaptable system to climatic conditions via actuators. The solution is designed with the aid of a customized workflow based on Ladybug Tools, which is calibrated according to recorded thermal-mechanical behaviours and allow to predict the energy and thermal/visual comfort dynamic performances. The system is tested in four European climates and sky types, tracing the scenarios of its adaptability under various settings. The results indicate that the system by its constant mechanical changes due to the variation of temperatures provides a higher degree of adaptation, energy-saving and indoor thermal and visual comfort.

Global warming affects the built environment with relation to its own characteristics, form, density. Heat waves effects would have limited effects if most of the cities would not be affected by Urban Heat Island that strongly increase their impacts (particularly on urban population). Does the choice of façade colours and materials contribute to this issue? The paper reports a research on a case study in Italy that tries to answer to this question comparing the trend in outdoor temperature increase closed to the building façade with relation to its colour and reflectance variations modelled by using Envi-met software. The outcomes point out that there is a correlation between the building façade reflectance and the temperature trend but this has a very limited influence on outdoor microclimate in open spaces as it varies in a range of less than 1 °C.

Despite studies on thermal comfort being consolidated in the scientific literature, people’s well-being in some specific conditions and places, such as hospitals, requires to be further explored. The paper describes the methodological approach adopted to evaluate thermal comfort level and perception of pregnant women hosted in the obstetric ward of a test-bed case (Sant’Orsola hospital in Bologna, Italy). The methodology adopts a mixed approach that compares the results of on-site monitoring by probe (as quantitative data) with the ones of a survey (questionnaire form) delivered to the involved subjects (as qualitative data) to understand if metabolic alteration may influence the pregnant women’s perception of comfort conditions. The first follows ISO 7730, the second, ISO 10551. The comparison between the instrumental collected data and the outcomes of the survey revealed a wide gap between TSV (Thermal Sensation Vote) and PMVm (Predicted Mean Vote, measured on-site). The reason can be identified in the use of a standardized metabolic unit from ISO that does not correctly reflect the physiologic condition of pregnant women. Following a trial and error methodology, a met value for pregnant women is accordingly proposed. Moreover, an adaptive thermal comfort approach is adopted. This research is a first step towards the definition of specific thermal comfort in a hospital ward hosting pregnant women and more generally offers a reflection about the need to define specific met in the standards for some particular categories (children, elderly, pregnant women, etc.) when investigating thermal comfort.

The scientific literature offers a wide range of studies evidencing the progress done in the retrofit actions dealing with the current building stock; however, renovations of hospitals are still an open field of research due to their typical complexity that is usually associated with a very challenging updating processes to maintain or increase operational level. The paper provides a synthesis of a study developed by a team of the Department of Architecture for Saint Orsola Hospital in Bologna with the scope to explore innovative retrofitting strategies. The brief provided by the management unit of the hospital was connected to the general renovation plan involving the entire site and particularly some existing buildings taking into account some limitations concerning budget availabilities and everyday activities needed to ensure acceptable service level for the end users. The design approach starts from defining a basic unit (a typical hospital room) that is deeply analyzed to report the starting conditions (indoor environmental parameters) and then used to simulate the potential impacts of retrofitting actions on its performances. The results allowed to parametrically develop a step by step strategy scaled on each building sector and on the building as a whole to evaluate the global impact on energy performances while considering time and costs of each retrofitting options.

Outdoor microclimate modelling is getting popular for estimating comfort conditions in urban environments. Current calibration approaches usually rely on measurements of air temperature for a limited number of points in the study domain, in spite of the fact that it is the Mean Radiant Temperature (Tmrt) the parameter mostly affecting comfort. However, the direct measurement of Tmrt outdoors via the globe thermometer or using the six direction radiation method is prone to errors. To overcome these issues, the present paper proposes a novel method to indirectly improve its estimate based on the use of infrared thermal pictures gathered by drone flights to measure surface temperatures, and then use these values for calibrating numerical models. This novel approach has been demonstrated for a 400 × 400 m2 wide area in the city of Medicina (Italy) and showed a good agreement with ENVI-met simulations, with average and standard deviation values difference between measured and simulated surface temperatures of 1.53 °C and 2.22 °C respectively. The highest differences (up to 19 °C) are found for areas densely covered by vegetation. Further studies are planned to evaluate the goodness of the calibration pixel wise and to propose calibration thresholds based on Tmrt sensitivity.

Knowledge of building techniques, materials and their decay is nowadays quite vast, as well as on the solutions and methodologies of a restoration project, which depends on the goal of the restoration itself. Even the choices on the new usage of historic buildings are often well considered. In the last few years, we have conducted some monitoring campaigns to obtain data related to four distinct buildings, differing in construction times, typology, location, current and historical uses. What has been discovered is that these buildings appear to be able to guarantee historical microclimates surprisingly overlapping to the parameters nowadays considered appropriate to conserve them and the historical patrimony they contain. In this article we show some explanatory results of four case studies from our research. The monitoring control, moreover, allowed us to develop the analysis further, from survey to virtual simulation. In this way it was possible to verify the effects of minimal variations in the architectural characteristics, such as opening or closing a window, covering an open yard, or else removing a cover, reducing the source of light etc. All of these managerial and architectural interventions have a significant effect on the indoor environment of buildings and can improve the conservation status of architecture, sometimes to such an extent that more costly and invasive restorations become unnecessary.

The increasing attention paid to the effects of climate change on the dense urban fabric of contemporary cities had led Public Authorities to develop local adaptation plans in order to suggest some effective measures to mitigate and reduce the impacts of urban heat island [UHI] and heat waves as well as to improve water management capacity. Among the suggested actions, the greening of in-between spaces of the built environment and the introduction of new green surfaces (roof and/or facades) in the framework of wider regeneration plans offers interesting perspectives and impacts. The paper reports the outcomes of a research activity run by the Department of Architecture and the Municipality of Bologna to investigate how to define/optimize the most effective arrangement of greening solutions with the aim to improve outdoor comfort conditions. The study takes into account several aspects including paved/green surfaces extension, the use of material, the geometry of the site, etc. and simulate the potential effects of changes using simulation software ENVIMET. Once the main features of each site are modelled the different deriving scenarios can be compared evaluating the different architectural, economical and practical constraints. The results are then compared with other factors, related to the social aspects, the use of the spaces, the perception of the sites, etc. A district of the city of Bologna is used as test bed in order to test the proposed methodology and the related potential impacts.

Despite many progress have been done in the renovation of the existing stock, retrofitting hospitals and other strategic buildings still represent a very challenging issue both for their complex articulation and for the need to maintain acceptable operational level. The paper reports a research activity, run at the Department of Architecture in cooperation with S. Orsola Hospital in Bologna, aimed at investigating innovative strategies for retrofitting to meet the highest energy efficiency standards at national level. The main goal of the administration was to set a renovation plan – taking into account some limitations concerning the existing building features and the budget availabilities – able to remarkably reduce energy demand while creating the minimum disruption for end users. The starting position of the research was to preserve the historical image of the building while defining a strategy to insulate it from inside. The novelty of design approach lied in defining a basic working unit which was associated to the typical room of the stay division that was used to analyse the starting conditions (indoor comfort and environmental parameters) and simulate via software modelling the potential improvements. This led to define a step by step strategy that was translated into global intervention scenarios while the basic working unit was properly re-designed and validated. This approach allowed to define a parametric strategy able to predict the impacts of renovation on each floor, on each wing and on the system as a whole while assigning a specific unit cost and a reliable renovation timing.
