Abstract

The availability of coherent long-term measured data on climatic variables and building parameters forms the basis for predicting, analyzing, and simulating the heating or cooling energy demand on buildings. This article analyzes measured 4-year data considering the test building with an insulated cavity brick wall with a massive outer brick leaf. The results show that the solar radiation and the thermal inertia of massive outer leaf of a wall have a significant effect on the heat loss and energy consumption of the buildings throughout Finland and Scandinavia. Based on the average outdoor air temperatures, the nominal calculated heat losses could be overestimated. For more accurate heat losses, the outdoor surface temperature should be applied as a boundary condition. The measured results were verified with finite element method.
