Indoor Thermal Climate Criteria and the Effects on the Overall Environmental Performance of Air-Conditioning Systems

The cooling loads of an office building vary with the desired indoor thermal climate. However, there is a lack of knowledge on how significantly the various indoor climate criteria affect the overallenvironmental performance of the air-conditioning systems. Here, we analyze the environmentalconsequences of the energy use, as well as the possible modifications of the system design andcorresponding use of materials. The analysis is based on a theoretical case study of an airconditioning system designed for a typical office building situated in Sweden.
