“…Mediterranean traditional buildings are usually considered "sustainable" and energyefficient due to their arrangement in compact districts [48,49] and to the use of specific architectural "types" [50][51][52] or technical "solutions" [53,54] on the building scale. However, the current energy emergency, the comfort requirements for users, and in-progress environmental changes can threaten this concept [55,56]. In fact, the latest study by the Building Performance Institute of Europe (BPIE) affirmed that practical restrictions in energy improvements on historic buildings depend on overarching authorities, whereas heritage buildings-even if not directly listed as such-are not excluded by mitigation strategies.…”

Focusing on the uncertainties of climate change and its effects on the built environment, on the energy responsibilities of residential building stock and on the dichotomy between the transformation and preservation of cultural heritage with a long-term perspective, this paper proposes a detailed methodology aimed at managing energy retrofit transformations and preservation actions in historic districts following “resilience thinking.” The proposed methodology pursues the traditional process of retrofitting for cultural heritage, and identifies—on building and component scales—a structural process aimed at: (i) recognizing and testing the adaptive qualities of traditional built constructions to climate change based upon the genius loci experience; (ii) diagnosing critical energy emergencies which occurred due to historical transformations or exposure to criticalities of climate change; (iii) identifying and managing improvement requirements according to priority levels of transformation (MUERI). The test on a representative case study in the south of Italy (Mediterranean area) highlighted some significant results: (i) the importance of compactness and of light-colored materials in fighting local microclimate alterations; (ii) the pivotal responsibility of roofs in current and future trends in energy consumption, promoting and testing both innovative and traditional solutions; (iii) the reduction into a limited number of buildings cases to assess, solving the complex and various combinations of features, with which suitable solutions and guidelines are associated.

“…Climate change will result in an increase in temperature and a change in the pattern of rainfall. The energy use, indoor climate, and humidity dynamics of historic buildings can be changed along with retrofit solutions [29]. Overheating is already a growing concern with regard to the internal climate.…”

Energy Efficiency Measures Applied to Heritage Retrofit Buildings: A Simulated Student Housing Case Study in Vienna

One pavilion was selected for deep retrofitting from the Otto Wagner area situated in the west of Vienna. The retrofitting process involves sustainable and energy-efficient construction to improve the energy performance and energy production potential of the building while preserving the cultural heritage and significance. This four-story pavilion was re-designed according to the proposed regulations of a net positive energy university building to become a student residence. Architectural, building envelope, and engineering interventions along with various changes were simulated through the Sefaira tool in the SketchUp model. These included: optimization of the U-values of the roof, walls, and floor; the addition of different layers of sustainable energy-efficient insulation materials to decrease the overall energy demand. The specific energy demands for heating, cooling, and lighting were decreased in the proposed model to reduce the total energy use intensity from 248.9 kWh/(m2 year) to 54.3 kWh/(m2 year) resulting in a 78.2% reduction. The main goal of this study is to try and achieve a net positive energy status building as part of the Otto Wagner area by improving the building envelope and integrating renewable energies. A total of 22.5% of the annual energy consumption was generated by the designed PV system. The selected building achieved the passive house standards in Austria by optimizing the energy performance with the proposed energy efficiency measures.

“…Due to climate change, studies in different countries observed a decreasing trend in heating load in the winter, and the dilemma of an increasing cooling load or uncomfortable conditions in the summer [14]. Although climate change reduces the heating loads in historic buildings, active systems are mostly inevitable to ensure thermal comfort of occupants and the preservation of historic buildings, increasing the total energy use [15].…”

Energy retrofits can enhance the liveability and efficiency of historic buildings while preserving their historic and aesthetic values. However, measures like improved insulation and airtightness may increase their vulnerability to overheating and climate change may further worsen their performance in the future. This paper investigates indoor overheating risks brought by climate change in retrofitted historic buildings and proposes effective adaptation strategies. Firstly, local weather conditions are analysed to identify homogenous climatic zones. For each climatic zone, “a business-as-usual” emissions scenario is adopted, and most representative regional climate models are selected to obtain hourly output of future climate projection. A comparative study is adopted where typical alpine residential buildings, “Portici house”, are simulated with regard to future energy use and indoor thermal state using the dynamic model in EnergyPlus. Energy use and indoor thermal conditions are compared before and after energy retrofit, as well as under present and future climate conditions. The results demonstrate that retrofit interventions could significantly improve energy efficiency of historic buildings in both present and future scenarios. A change in climate together with retrofit interventions will, however, result in higher risk of indoor overheating in South Tyrol. Potential negative side effects of energy retrofit could be controlled by adopting adequate shading and ventilation approaches that minimise, or eliminate, the risk of overheating during high temperature periods while optimising historic buildings’ energy performance.
