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.
Variable Frequency Drive (VFD) for HVAC Pump
VFDs control the speed of an HVAC pump 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.
Inverter Variable Refrigerant Flow Air Conditioner (IVRF)
An inverter variable refrigerant flow system provides individualized comfort and control in different zones in a building to minimize energy usage. An IVRF system can reduce 20-35% in energy use, maximize energy efficiency and help achieve a sustainable design.

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 $50 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. We also offer enhanced incentives for chiller projects that allow customers to: 1) select a study to methodically determine the facility’s load profile using metering, modeling or spreadsheet analysis to appropriately size the replacement chiller system; and 2) the installation of permanent kW/ton metering that measures the efficiency of the cooling system to optimize its performance and maintain the persistence of the energy savings.
