Abstract :
The sizing of the solar installation of an individual dwelling is a problem which can be solved in many ways. The approach described
in this paper is a simplified procedure of considerable interest. It requires only a small quantity of data and can be computed in a short
time. The performance of this procedure was evaluated by a more complex sizing method based on detailed simulation. The simplified
procedure was applied to the case of an individual dwelling using a solar collector field to produce domestic hot water and space heating.
The building and the solar installation have then been modelled with the software TRNSYS 16 and their behaviour was simulated during
a whole year. The results obtained are particularly close to the ones expected by the simplified sizing procedure.
