Fan usage

Presenting LOBSTER, an innovative climate chamber, and the analysis of the effect of a ceiling fan on the thermal sensation and performance under summer conditions in an office-like setting

Thermal comfort studies have been performed so far either in closed climate chambers with controlled conditions or non-controlled conditions during field studies. Detailed analyses of mechanisms behind the adaptive comfort models are therefore hardly possible. This paper presents a newly constructed climate chamber in Karlsruhe (Germany) along with the complete chain from subjective experiments, via data analyses, model development and implementation into dynamic building energy simulation until the formation of a decision base for or against a renovation measure for a confined case.

In order to know the thermal comfort of bedrooms, we have measured the air temperature and relative humidity in the 27 bedrooms of 11 houses. We have also conducted a thermal comfort survey, quality of sleep and occupant behaviour survey with the residents. Residents are highly satisfied with the thermal condition of the houses, using various thermal adjustments such as fans, clothing modifications, etc.
