Integrated Building Control Retrofit Package for Commercial Applications

The California Lighting Technology Center, in collaboration with the California Energy Commission, is conducting research to develop and evaluate technology that integrates automated controls for heating, ventilating and air conditioning (HVAC), electric lighting and dynamic fenestration systems. The integrated system is referred to as the Integrated Building Control Retrofit Package (IBCRP), as it is aimed for retrofit projects in existing commercial buildings. This integrated approach is anticipated to increase building-wide energy efficiency, reduce peak electricity demand and improve occupant comfort. 

The objectives of this project are to 1) develop an IBCRP, 2) evaluate the IBCRP in the laboratory and 3) install and evaluate the IBCRP in an existing building. To date, the IBCRP has been developed and evaluated in the laboratory.  Field demonstration activities are in progress.

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.
