Numerical results of a computer simulation using the RESHEAT code are made with experimental data obtained from side by side testing of a Radiant Barrier (RB) technology on a set of residential houses in the Southern MidWest. The code is a dynamic one dimensional heat transfer model which incorporates all the effects of heat through attics and building structures. The code also models the effect of radiant heat gain in supply air ducts placed in the attic. The code solves for temperature histories of over 90 nodal points around the structure and uses the hourly weather information already available in the open literature as its input. It was found that in a majority of cases where the experimental data was deemed reasonably accurate and without problem the code predicted the temperature profiles in the different attic layers reasonably well. In some of the experimental data, obtained by others, the validity of the data was somewhat in question.
