Abstract: HOT2000 is a key component of Canada’s home energy rating, labelling, incentive programs, and code compliance. Design professionals and builders also use HOT2000 to improve residential house design. The National Energy Building Code (NEBC) requires all software used for code compliance be evaluated in accordance with ASHRAE Standard 140. After its latest major revision, the most recent version of HOT2000 Version 11.3 needed to be tested in accordance with ASHRAE Standard 140-2014. The heating energy consumption results from HOT2000 version 11.3 were mostly within the range of Std 140 reference software for both Class I and Class II test cases. Apparent differences in how HOT2000 models solar gains and makes use of these gains for a building with high thermal mass resulted in over half of HOT2000’s cooling results being outside the confidence intervals. Within the context of whole house energy analysis (Class II test cases) for houses and lowrise residential buildings, HOT2000 does demonstrate consistent and acceptable energy use predictions. HOT2000 specifically is used for the whole house energy analysis.
