| Abstract: | A simple algebraic model for the evaluation of the average performance of passive solar dwelling units is presented. The model is based on a first order representation for the mass effect of walls and thermal energy balances for a dwelling unit, during the day and the night. The model requires as climatological input the mean temperature during the day and the night and the daily solar irradiation for each month. The model is capable of predicting the performance of both direct gain and storage wall systems and can be used to evaluate the effect of design parameter such as mass, internal or external insulation, temperature difference between day and night. |
