The heating, ventilating and air-conditioning (HVAC) system has a major influence on the comfort and quality of a building’s indoor environment. The HVAC system also accounts for 30 to 50 percent of a commercial business’s annual electric bill. The Electricity Costs chart shows an estimate of the cost to maintain comfort in various types of businesses.¹ When constructing a new building or renovating an existing one, this fact sheet can show how to take advantage of HVAC technology to reduce the cost of heating and cooling the space efficiently and economically.
