INVESTIGATION OF THE ENERGY FLOWS FOR TRANSPARENT AND NONTRANSPARENT BUILDING FACADE

Based on extensive measurements of energy usage for a variety of build ing facades, a computer model has been developed for calculating in ad vance the heating and cooling requirements of test rooms equipped with arbitrary facades. To simplify the predictive calculation, the three- dimensional physical model was transformed to a one dimensional, linea r, computational model. The computer model uses the results of art ear lier sensitivity analysis. This permits the precise numerical modeling of the measured results and gives special value to the adaptation of this model for describing the geometric and thermal relations investig ated experimentally. The results of the numerical calculations are fou nd to be in good agreement with the measurements For six test rooms. T his agreement justifies the linear numerical model and the computer pr ogram for predicting the energy flows in different room structures. Fu rther, the computer model not only provides results which follow the c ourse of weather conditions for the test year but yields results as we ll for a Standard Reference Year for the region.
