Heating, ventilation and air conditioning (HVAC) can account for as much as 30% of a building’s annual energy use. Any enhancements to improve the efficiency of these systems can yield significant savings on your energy bills. In addition, improving your HVAC system can increase comfort and indoor air quality, leading to better productivity, increased employee morale and greater profitability. Financial incentives can help you save up to 50% on qualifying energy efficiency measures and equipment upgrades, including: Unitary Equipment. Air-cooled unitary air conditioning and split systems, air-to-air heat pump systems and water source heat pumps are ideal for smaller commercial buildings and retail spaces where they can replace failed unitary equipment or be installed in new construction. Chillers. Whether constant or variable speed, chillers support central air conditioning for large commercial and industrial buildings. HVAC Controls. Using HVAC controls to power down heating and cooling loads when rooms or spaces are unoccupied can reduce electricity use by up to 40% compared to when occupants are present.
