Improving Thermal Insulation of Concrete Sandwich Buildings

Danish Building Research Institute (SBi), Aalborg University, 2970 Horsholm, Denmark, jma{at}traeinfo.dk

Increased requirement for the thermal insulation of buildings and reduction of energy consumption in order to decrease their carbon dioxide emission means that buildings only 30 years old are of a very low standard compared to today’s requirements. Therefore, there is a strong need to improve the insulation of many existing buildings. Improving insulation can be a risky business as experience has shown that different sorts of degradation will often occur after such work. On the other hand, improvement of the insulation could contribute to making a building more attractive to tenants.

This article deals with good technical solutions for improving the insulation of concrete sandwich panel buildings from the 1960s and 1970s as well as how the savings in supplied energy can be estimated in a simple and accurate manner.

Key Words: Refurbishment • Insulation • Energy saving • Concrete buildings
