The benefits of installing energy efficient lighting systems in commercial buildings are significant. Such systems can reduce lighting costs and, because less lighting power means less heat, decrease cooling energy costs and the required cooling capacity. Lower cooling requirements translate into lower cooling equipment first-costs in new construction and some retrofits. Although heating costs may rise, they virtually never exceed the cooling savings accrued by energy efficient lighting in commercial buildings, even where electric resistance heating is used. Calculating the lighting cost benefit is fairly straightforward. In contrast, understanding and accounting for the associated cooling savings and heating cost is more complex, requiring consideration of a variety of HVAC interactions. The easy-to-use Calculation Form included in this article helps minimize the effort required to analyze lighting/HVAC interactions. This form lets designers and engineers accurately calculate the cooling and heating effects of installing more efficient lighting systems in either new or retrofit situations.
