HVAC
Heating and cooling can make up as much as one-third of the energy consumed in a typical building. The below rebates 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 energy usage by 20-35%, maximize energy efficiency and help achieve a sustainable design.
Packaged, Split System, and Window AC
In Hawaii, “rooftop units,” or RTUs, make-up a majority of A/C systems used in our businesses. With A/C being one of the largest users of energy in your business, upgrading to an energy efficient version is a smart move. We provide rebates for new packaged or split system units that are at least 10% more efficient than our current energy code. New variable speed Window A/C units with a high enough Combined Energy Efficiency Ratio (CEER) will also qualify requirements.
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.
