Impacts of energy retrofits on hygrothermal behavior of Finnish multi-family buildings

Abstract

This paper presents impact of energy retrofit on hygrothermal behavior in three multi-family buildings. One of the buildings underwent deep energy retrofitting, one had focused energy retrofits, and one building was a non-retrofitted control building. The average indoor temperature during heating season was relatively high in all studied buildings. The temperatures near the coldest spot of the building envelopes were within guideline values, and some improvements could be noticed in the deep retrofitted building.
