Linking energy, comfort and health

As the comfort and health questionnaires provided data about the same children in the same classrooms and during the same period as the assessments of energy consumption and building characteristics, it was worth investigating the associations between these parameters in the case of the four participating EECCA countries.

The pairwise correlation coefficients of these variables show that the combined comfort indexes were significantly correlated with both of the energy indexes (see Annex). The correlation coefficients for CCI-2 were twice as high as for CCI-1. With the exception of any wheezing during the last 12 months, none of the investigated health symptoms correlated significantly with the combined comfort indexes. However, most of the respiratory and chronic cough symptoms were significantly correlated with the energy indexes.
