Web1 de jan. de 2012 · The 2006 Ontario Building Code (OBC) was updated on January 1, 2012. ... The flow chart starts with the number of heating degree days of more than 5000 or not, then the heating source electric or not, then the heating equipment efficiency level of greater than 78% and less than WebThe basic procedure for calculating degree days is very simple, and all you need is a maximum/minimum thermometer. Each day, record the high and low temperatures. Determine the average daily temperature by adding the daily high temperature and low temperature together and dividing by two: Ave. Daily Temp = (High Temp. + Low Temp.) … WebHeating degree day ( HDD) is a measurement designed to quantify the demand for energy needed to heat a building. HDD is derived from measurements of outside air temperature. The heating requirements for a given building at a specific location are considered to be directly proportional to the number of HDD at that location. jessica camilleri holding head
