I am delighted to let you know that we recently added a new PIER technical brief to our library on a topic that I think would interest your readers. We encourage you to publish this information in your magazine or newsletter, but please let us know if and how you decide to use the brief. A Word version and graphics are available on request.

Savings Persist with Monitoring-Based Commissioning (TB-39) shows how monitoring-based commissioning (MBCx), a program approach that combines permanent building-energy-system monitoring with standard retrocommissioning practices, can provide substantial, persistent energy savings. A pilot program conducted at 25 California university campuses demonstrated that MBCx has the ability to:

• Reduce peak-period electricity use and total annual energy use;

• Trend and benchmark building-performance data continuously;

• Catch problems with control systems that are normally hard to detect; and

• Identify cost-effective retrofit opportunities.

MBCx can be used in commercial and institutional buildings that have energy information or energy-management systems that are capable of trending building energy use.

This series of technical briefs are produced by the California Energy Commission’s Public Interest Energy Research (PIER) program, which aims to decrease building energy use through research that develops or improves energy-efficient technologies, strategies, tools, and building performance evaluation methods. Topics include lighting, HVAC, building envelope, and controls, and each brief distills volumes of research results into a two-page summary of the problem addressed, the solution, and the benefits of implementing that solution. view and download additional briefs here.
