An energy audit is a service where the energy efficiency of a house is evaluated by a person using professional equipment, with the aim to suggest the best ways to improve energy efficiency in heating and cooling the environment.
Increasingly in the last several decades, industrial energy audits have exploded as the demand to lower increasingly expensive energy costs and move towards a sustainable future have made energy audits greatly important. Their importance is magnified since energy spending is a major expense to industrial companies. This growing trend should only continue as energy costs continue to rise.
While the overall concept is similar to a home or residential energy audit, industrial energy audits require a different set of skill. Weatherproofing and insulating a house are the main focus of residential energy audits. For industrial applications, it is the HVAC, lighting, and production equipment that use the most energy, and hence are the primary focus of energy audits.
