Adaptive models and experimental data: a comparison between surveys’ results in offices.

The adaptive models could be an useful tool to verify people satisfaction about microclimatic conditions and the results could be applied to other similar situations. An open question is to check the real agreement between instrumental data and subjective answers obtained by questionnaires. The aim of the present paper is to find a relationship between experimental and subjective data, with experimental surveys in moderate environments such as eight offices at the University of Perugia. The selected environments are different for exposure, architectural features, HVAC systems, in room terminals, number of people inside. Indoor measurement sessions are correlated to external conditions, representative of spring season, in two different years. Data from questionnaires are often not in agreement with the instrumental ones: people tend to accentuate the discomfort sensations, both in cold and hot conditions.
