Small and medium commercial buildings account for nearly half of the energy consumed by commercial buildings in the United States. While energy retrofits can significantly reduce building energy consumption, buildings’ owners often lack the capital and experience to perform detailed energy audits and retrofit assessments. The purpose of this paper...

... authors first analyzed both heating and cooling energy loads and then the electricity loads. Figure 3 illustrates how the case study building's consumption of cooling electricity, natural gas for heating, and electricity for other uses varies over time; the lack of consistent consumption, and indeed, rising cooling and heating consumption, indicate that the case study building should be audited. While it is possible that changing weather conditions (i.e., hotter summers and colder winters) account for the increased cooling and heating consumption, this is not evidenced in the data. ...
