Abstract:

An analysis of solar-radiation records obtained at Scarborough, Ontario, indicates that the insolation in Canada can be significantly greater than the values given by Moons standard solar-radiation curves. It is possible to represent the solar data by a single analytical expression involving an atmospheric extinction coefficient and an apparent value of the solar constant. This expression allows the calculation of insolation on any surface and the determination of the time and date when the maximum insolation can occur for any surface. Simple expressions relate the time, date, latitude, building orientation, and the type of window glass and shading with the solar heat gain through windows. These can be used to program any digital computer to compute design values of the instantaneous heat gain through the windows of a building. Author
