Project Result

The recipient is finalizing installation of the smart controls with the windows shades, thermostats, and lighting at the demonstration site at the Barn in UC Davis. Due to COVID-19 and the shelter in place the building has been unoccupied. The research team is coming up with solutions on to simulate occupancy presence in the building to provide theoretical savings. The project is expected to end 3/31/2021.

The Issue

The traditional approach to building automation consists of a collection of independent control systems, one for each building end use, with limited or no communication among the individual devices. Several research efforts during the past decade were aimed at improving electric lighting or fenestration control methods, increase system reliability and reduce lighting energy use. However, few efforts accounted for the interdependence of lighting, fenestration and space conditioning systems and the consideration of the latter in an integrated approach to optimize whole building energy efficiency via a single, unified control platform.

Project Innovation

This project tests an integrated building control package that maximizes energy efficiency for existing commercial buildings. The project refines novel control algorithms that utilize shared device state and environmental data for lighting, fenestration and heating, ventilating and air conditioning (HVAC) systems. Sharing data from multiple device types will further improve overall, sustained, system performance and operation. Control algorithms prioritize lighting or heating/cooling savings based on climate and building design. HVAC system management leverages passive ventilation through windows and skylights and dynamic adjustment of HVAC set point dead bands. The goal of this project is to reduce electricity use by 20-30%. The project team's mission is to partner with manufacturers throughout the critical development and demonstration phases to give products the best chance for market success. The research team will leverage multiple advocacy tools to make the knowledge gained, experimental results, and lessons learned from this effort available to the public and key decision makers.

Project Benefits

This project seeks to improve sensor-controlled lighting and air conditioning systems by integrating and sharing information from multiple sensors, resulting in better quality indoor spaces with reduced energy cost. This research focuses on refinement and testing of an Integrated Building Control Retrofit Package. The includes the refinement of novel control algorithms that utilize shared device state and environmental data among lighting, fenestration and HVAC devices. This is a breakthrough because most lighting and HVAC controls operate independent of each other and this project hopes to integrate both.

Consumer Appeal

Consumer Appeal

This project develops systems which improve the functionality of lighting and heating, ventilating and air conditioning controls, and integrates operations with automated shading, natural ventilation, and air conditioning systems, to create more and comfortable indoor environments.

Lower Costs


This project could lower energy bills to commercial building owners that implement these control retrofits for HVAC, lighting and fenestration in their buildings.
