Heating Energy and Cost Evaluation of Sandwich Insulation Concrete System

Abstract:

It is essential to eliminate heat loss through the building envelope to reduce the energy consumption in buildings. However a significant loss of heating energy caused by thermal bridge between slab and external wall in internal insulation systems which were applied in the most apartments in Korea. To improve the performance of envelope, a sandwich insulation system was proposed. This paper evaluates the thermal performance, energy performance and economic efficiency of sandwich insulation system by comparing with internal insulation system. When the sandwich insulation system was applied, heating energy consumption was reduced by 17.8% compared with internal insulation system.
