Heating and Cooling High-efficiency packaged units and high-efficiency heat pumps provide the same cooling and heating capabilities as their standard counterparts while consuming less energy by integrating high-efficiency components and controls within their systems. The higher-quality components and controls found in premium-efficiency motors on fans and pumps and high-efficiency, water-cooled chillers allow these components of a central plant to perform more efficiently than standard equipment.
Parking Lot Ventilation Demand-controlled ventilation in parking garages turns on ventilation fans only when levels of carbon monoxide approach critical levels.
