A "model house" for quantitative and qualitative investigations of the relationship between heat energy consumption and heat insulation. The sides of the house are made of thermal insulation material with a square opening into which various plates can be fitted to serve as test walls. The interior is heated by an incandescent lamp which, if necessary, can be mounted in the calorimetric chamber and supplied with power via leads passing through the walls of the model. Various channels allow temperature measurements inside the chamber and at the inner and outer surfaces of the walls of the model.
