ABSTRACT
Simulation of active and passive solar systems is most frequently performed, using a program specialized for this purpose and not adequate for simulation of the thermal behaviour of the building. These programs often have a very poor or even missing building simulation ability. By integrating the simulation of active and passive utilization of solar energy in a building simulation program it is possible to analyze the interaction between the building and the devices for utilizing solar energy. In some cases the effect of a solar device on a building is in real lift not as high as predicted due to the synchronism between the direct gain and the gain from the solar devices. A program available for simulations of the building and the solar system, will better enable the designer to optimize the use of the buildings and the solar driven production of hot water for space heating and domestic hot water.
The paper describes the philosophy behind a tool for simulation and analysis of active and passive solar devices and their interaction with the building to which they are attached. A procedure for automatic generation of input parameters from a very limited number of input data are further described.
