The bioclimatic approch consists in adapting the building design and materials to the local climate. This includes every passive (or architecural) ways to improve the indoor environment quality, including daylighting or the thermal comfort, for example the passive cooling described in the attached paper. Active measures such as artificial heating or cooling are avoided as far as possible.

The psychrometric approach is one of the ways to evaluate the necessary measures ot achieve hygro-thermal comfort. A dot is reported for each hour on a psychrometric chart, which coordinates are the outdoor air temperature and moisture. This creates a cloud which is generally partly out of a comfort zone which limits are accpetable temperatures and humidity limits. The building should then be designed and built - as far as possible with passive measures, but also with artificial heating or cooling - so that the whole cloud corresponding to indoor climate are within the comfort zone.
