Abstract

This paper reports on the methods used to analyze the effect on thermal comfort and energy performance of incremental changes applied to the building envelope. The object of investigation was the "House of Earth and Light", a residence built in the hot and dry climate of the low Arizona desert. As new owners occupied the house in 2003, they experienced severe overheating in the living room. A series path method was developed to determine the effect on surface temperatures as a function of changes in floor, glass walls, and roof R-values as well as changes in the indoor air temperature. The mean radiant temperature (MRT) was then calculated for each incremental improvement while the indoor air temperature was changed in order to achieve a target operative temperature (OT) of 78°F. The effect of the incremental improvements on the energy performance of the building was analyzed by means of hour-by-hour calculations using the Energy-10™ simulation software.
