Analyzing Building Energy Use

Analyzing Building Energy Use

The ability to analyze utility bills allows an engineer to understand HVAC energy use and find ways to use energy effectively in buildings.

The first step in most HVAC design projects is to calculate heating and cooling loads. These calculations become the basis for sizing equipment and, when required, projecting energy use. While energy-use projections can be data- and calculation-intensive, even the most sophisticated procedures consist of little more than calculating the heating or cooling load at each outdoor temperature of interest, multiplying by the number of hours of each outdoor-temperature occurrence in a year, an
