The goal of an energy audit is of course to identify energy-saving opportunities, but also to increase asset values, lower ownership costs and promote environmental stewardship, human comfort, health, and safety. This is done by taking a comprehensive look at the energy consumption data associated with a commercial building, as well as the energy and resource-consuming infrastructures, to identify fiscally responsible, sustainable energy efficiency measures that reduce energy usage and carbon emissions.
