A method for predicting the monthly performance of a passive solar building based on frequency domain analysis and electrical transmission line theory is described. Massive building components are represented as three lumped (complex) impedances and admittances using electrical transmission line theory. The model using the lumped thermal parameters is driven with monthly average profiles of diurnal solar input and temperature variation to determine the dynamic thermal behavior of the building. The monthly average input profiles are expressed using Fourier transform theory. The model is then solved for each frequency in the driving functions and the results are superposed to determine the outward heat flow. The results from the model provide the diurnal variation in outward heat flux and indoor temperature variation as well as monthly auxiliary heating requirements.
