I am trying to simulate the same building in DOE2 and e+ in order to compare the sensible heating and cooling loads calculated by both programs. I just uploaded the related e+ and DOE2 files to the site. Both files were saved with the name 1B. The building is a two-storey-high building with windows along the walls of the upper floor. The floor of the upper floor has been simulated as an adiabatic interzone surface in both programs. There are no people, equipment, lights, infiltration or ventilation in the building. Same window construction has been designed in Window5 and imported into e+ and DOE2. In e+ input file, detailed inside and outside convection algorithms have been used as well as the rain and snow indicators of the weather files. Attached are the graphs which show the sensible heating and cooling loads of the upper floors calculated by DOE2 & e+. The results pointed out that the sensible cooling load for the upper floor of e+ building was 3.2% lower than that of the DOE2 building. The sensible heating load for the upper floor of e+ building was 15 % lower than that of the DOE2 building. The total sensible building load for the upper floor of the e+ building was 8.3 % lower than that of the DOE2 building. 15% difference in sensible heating load made me concerned. Do these results make sense to you or am I missing something? Would you help me with this? Thanks, |
