HVAC

Heating and cooling can make up as much as one-third of the energy consumed in a typical building. The below incentives can offset costs and help you to make investments that reduce your energy consumption and lower your energy bills.


Hotel Room Energy Management System

The installation of energy management systems in hotels gives thermostat controls to existing guest room air conditioning systems through the use of occupancy sensors.

Variable Frequency Drives (VFDs) for HVAC Fans

VFDs control the speed of an HVAC fan by varying the electrical frequency depending on how much (or how little) power is needed at a given time. The less speed, the less electricity used. VFDs also reduce wear and tear on the system.

Air and Water-Cooled Chillers

Chillers are used to cool larger facilities. Most chillers have a service life of 10 to 20 years and can account for up to 35% of a facility’s electrical energy use. Hawaii Energy offers a standard chiller incentive of $45 per ton for air and water-cooled chillers that meets the Hawaii Energy Premium Efficiency IPLV (kW/ton) table. You can find this table on the worksheet.
