| Abstract | This project was based on recent studies at the Canadian Centre for Housing Technology (CCHT) that demonstrated the effects of energy efficient furnace fan motors on both electricity and natural gas use. Electronically commutated motors (ECM) were shown to reduce the kWh required in moving air constantly by ~75%. This resulted in a reduction in total house electricity consumption during the heating season by ~ 25%. In other parts of the year there is a similar reduction in kWh required for constant movement of air, and a further reduction in the electricity required for cooling by ~10%. At the same time natural gas use for heating is increased by ~14% in order to maintain a proper energy balance owing to missing motor heat. The net effect is still a significant reduction in utility bills (electricity and natural gas), and there will also be a significant net reduction in greenhouse gas (GHG) emissions if the kWh are produced from fossil fuels, particularly coal. |
