“…Such integral framework will help to cut off possible routes of aerosol transmission and thus contribute to control the epidemic spread. (ii) Big geodata such as street view images and points of interest (POIs) can be used to obtain voluminous URDs to increase the samples from a variety of sources besides very high-resolution remote sensing images ( Berawi et al, 2020 ; Kontokosta & Malik, 2018 ; Yan, 2017 ; Yang et al, 2021 ). Some of its impacts are evident for adding representative URDs (including the extension of classification and increasement of hierarchy) and improving the computing accuracy of wind resistance coefficient.…”

“…The most recent studies regarding climate change on energy demand point to the strong likelihood of lower heating demand in the future, while cooling demand may increase (e.g., [23][24][25][26]). In contrast, research on the impact of climate change on the potential of renewable energy generation in Europe is not consistent.…”

Climate change can strongly affect renewable energy production. The state of the art in projecting future renewable energy generation has focused on using regional climate prediction. However, regional climate prediction is characterized by inherent uncertainty due to the complexity of climate models. This work provides a comprehensive study to quantify the impact of climate uncertainties in projecting future renewable energy potential over five climate zones of Europe. Thirteen future climate scenarios, including five global climate models (GCMs) and three representative concentration pathways (RCPs), are downscaled by the RCA4 regional climate model (RCM) over 90 years (2010–2099), divided into three 30-year periods. Solar and wind energy production is projected considering short-/long-term climate variations and uncertainties in seven representative cities (Narvik, Gothenburg, Munich, Antwerp, Salzburg, Valencia, and Athens). The results showed that the uncertainty caused by GCMs has the most substantial impact on projecting renewable energy generation. The variations due to GCM selection can become even larger than long-term climate change variations over time. Climate change uncertainties lead to over 23% and 45% projection differences for solar PV and wind energy potential, respectively. While the signal of climate change in solar radiation is weak between scenarios and over time, wind energy generation is affected by 25%.

“…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]. The relative increases in energy demand will require an increase in energy generation capacity of traditional energy systems which has small flexibility [16]. This points to an urgent need for proper energy retrofit strategies set for historic buildings in the future.…”

Overheating Risks and Adaptation Strategies of Energy Retrofitted Historic Buildings under the Impact of Climate Change: Case Studies in Alpine Region

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.
