Abstract

SYNOPSIS The present paper describes two new computer programs, BTS and COMFORT. The first was written to help simulate the performance of a new passive cooling and heating system, designed by the author for buildings in North Africa. BTS is based on a simplified version of the admittance method. The main algorithms empolyed in the program are presented. Finally a validation proceedure was applied against an independent full scale experiment. Good agreement was obtained. The second program was written for the prediction and analysis of human thermal comfort. The program incorporates six thermal comfort indices; three original and three modified versions of the original. The original indices are: Fanger's Comfort Equation, Charma's Tropical Summer Index and Madsen's Equivalent Temperature. Results produced by the program are presented, for the six indices, in terms of the same Predicted Mean Vote, (PMV scale). The six indices are, however, classified as three for summer and three for winter.
