This paper addresses the effects of long-term climate change on retrofit actions on a school building located in a Mediterranean climate. Dynamic energy simulations were performed using Termolog EpiX 11, first with conventional climate data and then with future year climate data exported from the CCWorldWeatherGen computational software. To date, many incentive actions are promoted for school renovations, but are these measures effective in preventing the discomfort that will be found due to overheating generated by climate change? Today, one of the main objectives in retrofit measures is the achievement of ZEB (Zero Energy Building) performance. Achieving this target requires first and foremost a high-performance envelope. This study evaluates the impact of retrofit strategies mostly applied to the school building envelope, over the years, considering three different time horizons, until 2080. Thermal performance indices and indoor operative temperature under free-floating were evaluated. The results highlight that, with a changing climate, it is no longer possible to assume a constant static condition to evaluate retrofit actions, but it is necessary to develop a predictive mathematical model that considers the design variability for future years. There is an urgent necessity to ensure both the safety and comfort of buildings while also anticipating future variations in climate.

“…In addition, many studies revealed that this trend may happen even in energy efficient dwellings. Da Guarda et al [18] analyzed the vulnerability of a zero-energy building (ZEB) to the impact of climate change in 2020 (2011 to 2040), 2050 (2041 to 2070), and 2080 (2071 to 2100). Results showed that due to the increase in cooling energy consumption, there will be a power generation gap up to 40.2% for the 2080 period.…”

The building energy performance pattern is predicted to be shifted in the future due to climate change. To analyze this phenomenon, there is an urgent need for reliable and robust future weather datasets. Several ways for estimating future climate projection and creating weather files exist. This paper attempts to comparatively analyze three tools for generating future weather datasets based on statistical downscaling (WeatherShift, Meteonorm, and CCWorldWeatherGen) with one based on dynamical downscaling (a future-typical meteorological year, created using a high-quality reginal climate model). Four weather datasets for the city of Rome are generated and applied to the energy simulation of a mono family house and an apartment block as representative building types of Italian residential building stock. The results show that morphed weather files have a relatively similar operation in predicting the future comfort and energy performance of the buildings. In addition, discrepancy between them and the dynamical downscaled weather file is revealed. The analysis shows that this comes not only from using different approaches for creating future weather datasets but also by the building type. Therefore, for finding climate resilient solutions for buildings, care should be taken in using different methods for developing future weather datasets, and regional and localized analysis becomes vital.

“…Similarly, numerous studies conclude that in regions with a warm climate, the heating energy consumption (EC) of buildings will decrease. At the same time, the cooling EC will increase in conjunction with an increase in days of indoor thermal discomfort [17][18][19][20][21][22][23][24][25].…”

Dynamics of Changes in Climate Zones and Building Energy Demand. A Case Study in Spain

et al. 2021

In the current context of the climate crisis, it is essential to design buildings that can cope with climate dynamics throughout their life cycle. It will ensure the development of sustainable and resilient building stock. Thus, this study’s primary objective has been to demonstrate that the current climatic zones for buildings in peninsular Spain do not represent the current climatic reality and are not adapted to climate change and the impact on the energy demand of buildings. For this reason, the climatic zones of 7967 peninsular cities have been updated and adapted to the RCP 4.5 and RCP 8.5 scenarios by using the data measured in 77 meteorological reference stations. The results obtained have shown that in more than 80% of the cities, buildings are designed and constructed according to an obsolete climatic classification that does not take into account the current or future climatic reality, which will significantly affect the thermal performance of a building and highlights the need to review the climatic zoning in the country. The results obtained can be extrapolated to other regions. The methodology defined in this work can be used as a reference, thus making an essential scientific contribution in reflecting on current capacities and the possibilities of improving the building stock.
