This study compares the overheating risk of eight typical Danish residential buildings for today and future climate scenarios. The study includes four single-family and four multi-family houses, various renovation strategies, and two occupancy loads. Building performance simulation is employed to conduct 3012 simulations (using IDA-ICE), and the comparison of the overheating potential is conducted using the Indoor Overheating Degree (IOD). Results showed that the multi-family houses have a slightly higher overheating risk than the single-family houses. The building with the highest overheating risk was the one-story single-family house (1951–1960) characterised by a large unshaded glazed area. The most effective renovation strategy to reduce overheating resulted in being the window replacement. For the single-family houses, the renovation of the baseplate or the floor to an unheated basement was causing overheating. As for the multi-family houses, renovation of the external wall led to the largest increase in overheating in relation to the unrenovated case. The investigation of the future climates showed that overheating could increase with rising outdoor temperatures, whereby the interaction between temperature and solar radiation is a crucial factor.

本研究比较了八座典型丹麦住宅建筑在当今和未来气候情景下的过热风险。该研究包括四个单户住宅和四个多户住宅、各种翻新策略和两个入住负荷。建筑性能模拟用于进行 3012 模拟（使用 IDA-ICE），并使用室内过热度（IOD）进行过热潜力的比较。结果表明，多户住宅的过热风险略高于独户住宅。过热风险最高的建筑是单层独户住宅（1951-1960 年），其特点是大面积的无阴影玻璃区域。减少过热的最有效的翻新策略是更换窗户。对于单户住宅，将底板或地板翻新为未加热的地下室导致过热。对于多户住宅，外墙的翻新导致过热的增加相对于未翻新的情况最大。对未来气候的调查表明，过热可能会随着室外温度的升高而增加，因此温度和太阳辐射之间的相互作用是一个关键因素。
