Healthy and comfortable microclimate conditions are
essential for any type of environment but, in particular,
schools are a category of buildings in which a high level of
environmental quality may considerably improve occupants’
attention, concentration, learning, hearing and
performances [1,2].
The first scientific studies about the effects of the thermal
environment quality in classrooms on the students’
performances began around the middle of 1950. An
interesting review of the results of these first studies, lots
of them performed as field studies, is gives in the work of
Pepler and Warner [3]. After this period, the birth of the
Fanger theory about thermal comfort based on the results
from a fully controlled climate chamber [4], broke the
developing of new field researches on thermal comfort. But
the growing interest in the last years about the adaptive
theory of thermal comfort [5,6] has again stimulated
researches by field studies aimed at qualifying the thermal
environment both objectively (by measurements) and
subjectively (by occupants judgments).
