Clothing insulation is one of the parameters that have to be assumed when thermal comfort ranges are specified during design of heating and cooling systems. Current design practice is to follow examples from thermal comfort standards (DS/EN 15 251, DS 474) which specify "average" clothing insulation of 1 clo during winter and 0.5 clo during summer. Most of the designers forget, that the standards also recommend an analysis of each individual design-case with respect to occupant activities, behaviour, dress-code etc. The consequence is that when building is given into operation, the design set-points, based on examples from the standards, are applied to actual controls for heating and cooling. Recent study conducted at DTU Byg showed that an average clothing insulation in Danish office buildings during winter/early spring was 0.8 with minimum values as low as 0.57 and maximum over 1 clo. Such differences in clothing insulation levels naturally lead to thermal discomfort for particular groups of building occupants. Consequently, their work performance may be reduced, which can be associated with increased costs for their employers due to lower productivity.

Aim of the project is to develop a control algorithms for heating and cooling for office buildings that take clothing insulation of the occupants into account.

Building performance simulation tool IDA ICE will be used for the purpose of the study. The developed algorithms will be evaluated based on their ability to improve thermal comfort. Moreover, their influence on energy consumption will be also investigated.
