Occupancy-based controls have been deployed by various utilities and their customers to control lighting, and heating, ventilation and air-conditioning (HVAC) loads in various building types. These installations have resulted in reported energy savings often exceeding 20%. As this can represent a significant conservation opportunity for both gas and electricity, the sponsoring gas and electric utilities have shown an increased interest in learning more about this suite of technologies and assessing the energy savings potential within their service areas.

This report assesses the technical savings potential of occupancy-based controls, as well as their overall conservation potential within the service territories of the sponsoring utilities. Although the majority of market activity to date has involved occupancy sensors applied as a lighting control strategy, the study also examines the potential for occupancy-based controls in emerging applications, including HVAC and plug load control. This report addresses opportunities for electricity and natural gas savings across multiple building subsectors, including hotels/motels, multi-family residential buildings, and office buildings.

The study identifies a significant technical opportunity for energy conservation through the use of occupancy-based controls in each of the sponsor utility’s service areas, although a variety of economic and market barriers currently limit their uptake.
