The aim of the study is to develop a model for the energy balance of buildings that includes the effect from the radiation properties of interior and exterior surfaces of the building envelope. As a first step we have used ice arenas as case study objects to investigate the importance of interior low emissivity surfaces. Measurements have been done in two ice arenas in the north part of Sweden; one with lower and one with higher ceiling emissivity. The results show that the low emissivity ceiling gives a much lower adiation temperature interacting with the ice under similar conditions. The dynamic modelling of the roof in ice arenas shows a similar dependence of the roof-to-ice heat flux and the ceiling emissivity.
A second part of the study focus on how to realise paints with very low thermal emissivity to be used on interior building surfaces.
