An App based on the BC hydro/Fortis/Powersmart “Enhanced Thermal Performance Spreadsheet”. The app calculates the impact on the clear field of a wall elevation from the thermal bridging effects of linear transmittances (foundation, floor, roof, corner, window/doors) and point transmittances (signage, etc.)
