This paper presents the newly developed Indoor Climate Library. The library facilitates simulation of the coupled heat and moisture transfer through envelopes and the interaction of envelopes with the interior air. The computation of coupled heat and moisture transfer becomes more and more important for the development of electric vehicles. Due to the lack of waste heat from the combustion engine the heating of a vehicle cabin during winter time becomes a challenge. One way to reduce heat losses through the envelope is to add insulation. However; insulation bears the risk of water accumulation and its performance usually decreases with increased water content. The Indoor Climate Library helps the user to detect such problems early in the product development process and to find remedies.
