| Zusammenfassung: | Recently, the UK has experienced air temperatures in excess of 40 °C for the first time, smashing previous records. We initially adapt to excessive heat by moving into the shade. Air temperatures are always read in the shade: the sun's radiation does not directly affect the temperature reading. The primary adaptation response is therefore to reduce our direct component of solar radiation, moving behind a tree or building, but this has little impact on the diffuse component of solar radiation coming from the clouds and sky (the direct solar beam scattered by molecules or particulates in the atmosphere) or the air temperature. This guide highlights some of the issues associated with the discrepancies between blind performance in a model and in a real-life application. Future software applications will need to align with the relevant standards. This guidance also recognises that shading systems, such as internal blinds, simultaneously affect internal daylight and acoustic conditions as well as the thermal and solar performance of a building. |
