Bonus savings from air-conditioning

27 Apr 2016

In medium to large offices, the number of people and presence of equipment and lights all generate extra heat.This adds to the load the cooling cycle of air-conditioning systems has to deal with.That’s why even in Australia's coolest cities it takes more energy to cool office blocks over a year than it does to heat them

Estimating the air-conditioning energy savings due to efficient office equipment is complicated by two factors. Firstly, air-conditioners typically produce two to three units of cooling for every unit of electricity consumed (that is, their coefficient of performance or “COP” is between two and three). So, to remove a kilowatt-hour of heat energy requires between a third and a half a kilowatt-hour of electrical energy. Secondly, in cold weather the heat from office equipment may help heat the building, saving on heating from
