Luminaire Level Lighting Control (LLLC) uses a network of temperature, lumen, and occupancy sensors located at or near individual electric light fixtures for the purpose of localized system control that can reduce energy use and improve occupant satisfaction. Typically, LLLC is used to control electric lighting systems. The intent of this study is to investigate how LLLC can be integrated into the control sequencing of heating ventilation and air conditioning (HVAC) systems through a building automation system (BAS), and to study whether LLLC + HVAC integration can reduce energy use while improving occupant comfort.

A two-story 60,000 SF office building with LLLC installed on one floor has been identified as the study site. Current operational control sequence and energy use data will be collected as baseline. HVAC integration measures will be developed and tested for energy use and occupant thermal comfort. Smart Receptacles will also be installed to study the energy use reduction possible from plugged equipment using this technology.

This ongoing research project is supported by the Northwest Energy Efficiency Alliance (NEEA).
