BEIZAEE, A. ... et al., 2012. Assessing the ability of PMV model in predicting thermal sensation in naturally ventilated buildings in UK. IN: Proceedings of the 7th Windsor Conference: The changing context of comfort in an unpredictable world, London, 12-15 April 2012, 17 pp.
A study was conducted to investigate the accuracy of the PMV model for predicting
thermal comfort sensations in naturally ventilated residential and office buildings in
the UK. Sixteen participants participated in identical thermal comfort studies at both
their homes and their offices. Environmental variables affecting thermal comfort were
recorded while the participants voted their thermal sensation in both locations. The
comparison of reported thermal sensation and those predicted using ISO 7730 showed
that in general PMV under predicts the thermal sensation of occupants in both
environments. The neutral temperatures found in homes and offices were 23.4ºC and
23.2ºC which were respectively 3ºC and 2.5ºC lower than those predicted using ISO
7730. Together with 0.2ºC difference found between reported neutral temperatures at
homes and offices, this suggests that there could be a context influence affecting
occupants’ thermal sensations in home and office environments.
