Commercial Building Electric Energy Consumption
Lighting fixtures consume the largest amount of electric energy in commercial buildings, three times the energy consumption of air conditioning. According to research report from the Energy Information Administration (EIA), lighting consumes the largest amount of electricity in commercial buildings as measured by Kilowatt-hours (KWH) per Square Foot KWH per Sq Ft provides a useful means of measuring the energy intensity of a building. Commonwealth Energy Group is able to provide a comprehensive energy audit to identify what fixtures and factors consume the most electric.

Lighting Fixtures in Commercial Buildings

Lighting Fixtures in Commercial Buildings
According to the Commercial Buildings Energy Consumption Survey, conducted by the EIA in 2003, found that only 23% of all commercial buildings employ energy efficient lighting fixtures. Buildings relying on older legacy fixtures are spending significantly more on utility expenses.

According to Figure 2 Lighting Fixtures in Commercial Buildings, most commercial buildings, even those built after 1980, still rely on legacy incandescent and standard fluorescent light fixtures. These legacy fixtures are very inefficient in comparison to today’s more energy efficient lighting technology available now.
