WebMechanical Engineering questions and answers. Heating Degree days (HDD) of Vancouver can be considered as 2800 F. Consider a building with an overall heat loss factor of 480 Btu/hr-F. What is annual heating load of this building. Consider furnace and distribution system efficiencies of 80% and 75% respectively. WebHeat loss from the house is from two sources: walls and the roof. Heat loss from each of these sources for a year (season) can be calculated by using the following equation. Heat Loss from Walls = 1, 248 f t 2 × 10, 500 o f-d a y s × 24 h d a y 13.0 f t 2 o f h B t u = 24.19 M M B t u. Heat Loss from Roof = 1, 150 f t 2 × 10, 500 o f-d a y s ...
