CLTC is developing an integrated building control system for existing commerical buildings. To date, few research efforts have accounted for the interdependence of lighting, fenestration and HVAC systems and the consideration of HVAC status in an integrated approach to optimize whole building energy-efficiency via a single, unified control platform.
The system in development includes a unique integrated building control strategy that will deliver an improved visual and thermal environment for building occupants. Additionally, widespread adoption of such a retrofit package could save commercial ratepayers 20-30% of electricity used to light and cool their buildings and facilities as compared to a building without the retrofit package.
