Advanced Lighting Control System Assessment
Project Number ET09SDGE0013 Organization SDG&E End-use Whole Building Sector Commercial, Public Project Year(s) 2009 - 2010
In response to the whole building approach to achieve energy efficiency, San Diego Gas & Electric’s Emerging Technologies Program’s (ETP) objective with this assessment was to:
* assess the energy efficiency potential of an advanced lighting control system
* determine the difficulty of properly installing an ALCS
* understand occupant acceptance of light levels
Despite the significant potential benefit to energy utilities and their customers, several barriers to the widespread promotion and adoption of advanced lighting control system technologies exist:
1) Added cost (dimming ballasts, complex installation, commissioning, ongoing operations, IT overhead).
2) Feasibility (wiring not possible without major retrofits, lack of staff who can operate the system, integration with existing building controls).
3) Lack of knowledge that such a system exists.
4) Lack of acceptance (perceptions of light levels being too low, maintenance being too complicated or of poor cost/benefit).
This project will provide:
1) better understanding of advanced lighting control systems and the proper installation and commissioning
2) true energy reduction and operational cost benefits
By doing so, this project will help address cost and feasibility barriers and increase implementation.
