Recent year’s extensive power failures have put focus on the importance of secure local production and distribution of energy. Since district heating (DH) is the dominating heating system in Scandinavia it is of great importance to investigate the possibility for buildings connected to DH to receive heat during an electric power failure.

By using computer models; buildings’ heating systems can be simulated; and by comparing the results with field studies the model can be evaluated. The model shows good resemblance with the field study.

By using a model the influence of different parameters can be studied. The influence of; e.g.; changed primary supply temperature and outdoor temperature can be studied.
