A field study of the performance of the Dutch Adaptive Temperature Limits guideline

Field measurements and recording of occupant thermal responses and behavioral actions in 4buildings clearly demonstrates adaptation: at higher outdoor temperatures, higher indooroperative temperatures are judged as comfortable by the occupants. The comfort voteshowever didnt relate well with the climate types Alpha and Beta as determined according tothe Dutch ATG guideline. But when the climate types were restructured on the basis of theoccupants perceptions the comfort temperatures match very well with the climate types.Furthermore, compared to the former GTO-guideline a higher cooling capacity is needed tokeep the indoor temperature strictly below the ATG-limit, but when the temperatures areallowed to exceed this limit for some 5% of the time, both GTO and ATG lead to almostsimilar capacities.
