Assessment and comparison of thermal sensations for a traditional and modern building

The proper design of buildings should ensure that the indoor conditions are
comfortable, and users experience thermal comfort throughout the year, especially in
sophisticated, modern intelligent buildings. The existing model of thermal comfort comes from
the 60’s/70’s and was the basis for the ISO 7730 Standard. It utilizes the concept of the PMV
(Predicted Mean Vote) and PPD (Predicted Percentage Dissatisfied) indicators. The current
paper compares the actual expressions of people (as indicated by them in the anonymous
questionnaires) with the PMV/PPD values calculated according to the Standard. Differences
between these values have been discussed and conclusions have been drawn as to the usability
of this thermal comfort model in intelligent buildings, which still seem to be a novelty in Central
European countries and data on their thermal comfort performance is still quite modest.
