Multiclimate comparison of the improved TC 4.7 simplified energy analysis procedure with DOE-2

The TC 4.7 simplified energy analysis procedure (SEAP) does not consider thermal mass, and its predictions differed substantially from those of a major hourly simulation program when solar influences were substantial (Brotherton et al. 1987). ASRAE Research Project RP-564 was initiated to improve the thermal mass and solar performance of the SEAP. A method for treating thermal mass and an solar treatment for the SEAP are described in companion papers (Claridge et al. 1992; Vadon et al.1991). This paper compares the performance of the SEAP incorporating these modifications with the original SEAP and with the hourly simulation program DOE-2 for 45 different cases in each of four climates. The modified SEAP shows better results in more than 80 % of the cases examined. In the remaining cases, comparison to DOE-2 predictions are similar or have worsened.
