Specific Building Type 73 by International Energy Agency This type is specific to La Chaumiere. IEA did not make a general building type. This type represents one stage of la Chaumiere thus 4 units are needed for Exercise A1. This building model is a simplified dynamic and multizone model. Each zone is represented by a second order lumped parameter model. A zone has only one temperature. This model is further described in the synthesis report and in the Annex 10 data bank. It uses the equivalent sol air temperature. The weather data must contain the outside temperature and 4 sol-air equivalent temperatures: one for each zone connected to the outside.
