Automated Demand Response: Recommendations for Demand Management
CEA worked to improve the practical implementation of automated demand response requirements. Current code under the 2016 Energy Stanards requires ADR capability but does not require installation of appropriate ADR communication equipment, which is necessary for participation in California utility ADR programs. To address this critical issue, CEA worked with the California Energy Commission and other stakeholders to clarify and update existing requirements.
CEA recommendations included:
1. Use of a common communication protocol for ADR, namely OpenADR 2.0a or newer.
2. Requirements for a gateway device on the premise that can receive an OpenADR 2.0a or newer signal and can communicate with that information to building lighting systems.
3. Clarifications on lighting reduction behavior after receiving a demand response signal.
4. Clarifications on controlled load types to allow for minor non-controlled areas such as closets, storerooms and utility areas.
Lighting System Alterations: Recommended Updates to Section 141.0
CEA believes that existing buildings represent a vast, untapped opportunity to achieve energy and carbon savings in California. Reducing the impact of lighting, which consumes between 20 and 30 percent of all commercial building energy use, is key to meeting California's savings goals.
To support improvements in existing building's energy efficiency, CEA authored a code change proposal dedicated to improving the lighting control requirements for lighting alterations.
The primary goals of CEA's code change proposal were:
1. Improve the adoption of energy-efficient lighting systems that enable existing buildings to improve their Zero Next Energy readiness. 2. Improve overall compliance with the Energy Standards in existing buildings. 3. Exceed energy savings currently expected for California's existing buildings as compared to savings expected for lighting alterations completed in compliance with the 2016 Energy Standards.
To achieve these goals, CEA recommends simplified language with reduced application and/or project-specific requirements; an easy-to-understand energy savings option for small buildings and tenant spaces; and a universal compliance threshold and set of exemptions.
