Abstract: Over 25 years ago, Natural Resources Canada initiated a project to replace HOT2000. They argued that with new “modern” computers, that the monthly bin-method employed by the software was no longer justified given advances in CPU speed and disk storage. The bin-method introduces basic limitations such that it cannot effectively model passive solar effects, controls for HVAC systems, thermal comfort, indoor air quality, etc. Unfortunately, they failed to successfully deliver a successor, and HOT2000 remains the tool being used for almost all part-9 energy modelling across Canada. An industry survey was conducted and shows interest to have a new software tool that includes features that could help provide better design guidance for both climate mitigation (net-zero carbon, embodied carbon, renewable energy) and adaptation (thermal comfort, indoor air quality, backup power).
