The Applications Team is a joint venture of the Energy & Environment Division and the Lab's Facilities/In-House Energy Management Section. Its goals are to speed the transfer of new and underused energy-efficient technology for buildings, to support demonstrations of these technologies in a variety of facilities showing how they can be adopted widely, and to improve communication between the Lab and the users of efficient building technologies, from engineering construction firms to building managers. The A-Team is involved in a growing number of chiller plant efficiency projects aimed at demonstrating how cooling systems in many settings can be made more efficient.
In addition to the projects described in the cover story, A-Team efforts in chiller retrofit include:
- The Advanced Data Visualization project, which focused on several chiller plants to develop and demonstrate new tools for performance analysis.
- Providing input to DOE and GSA on their standard chiller procurement initiatives.
- Support on chiller plant design and retrofit in numerous Federal Energy Management Program design assistance projects. For example, the Presidio of San Francisco is considering a retrofit and right-sizing of a 500-ton chiller in an oversized chiller plant.
- Metering and monitoring of numerous chiller plants for tuning, retrofit assessment, thermal storage sizing, and baselining under energy savings performance contracts. For example, an LBNL building was the DOE pilot test for a comprehensive energy savings performance contract. Chiller plant savings are measured using a baseline regression model incorporating weather, process electrical use, and gas use. Another recent example was an instrumented study on numerous air conditioners at a U.S. embassy in India.
- Developing National Measurement and Verification protocols and FEMP M&V
- A CIEE project to improve the energy efficiency of laboratory and related facilities in California. The focus of this project is to produce a design guide that, among other benefits, reduces chiller oversizing and optimizes part-load chiller plant efficiencies.
