In addition, integration of the WINDOW 4 program was accomplished resulting in improved ability in analyzing window energy performance. An improved algorithm for calculating the outside surface film coefficient was implemented. One of the most significant recent moreВ В» changes in the program occurred with version DOE-2.1E. Table 2 provides a listing of additions and modifications that have been made to various versions of the program since version DOE-2.1A. Discrepancies discovered during the course of such work has resulted in improvements in the simulation algorithms. Validation studies in which calculated simulation data is compared to measured data have been conducted throughout the development of the DOE-2 program. The intent in providing the results of these validation studies is to give potential users of the program a high degree of confidence in the calculated results.

RESFEN 3.1 is a program specifically dealing with analyzing the energy performance of windows in residential buildings. This work is part of an effort related to continued development of DOE-2, particularly in its use as a simulation engine for new specialized versions of the program such as the recently released RESFEN 3.1. Results for several versions of the program are presented with the most recent study conducted in 1996 on version DOE-2.1E and the most distant study conducted in 1981 on version DOE-1.3. This report documents many of the validation studies (Table 1) of the DOE-2 building energy analysis simulation program that have taken place since 1981.
