As part of its work, the California Energy Commission operates a Research Development and Demonstration (RD&D) Division, which oversees the Public Interest Energy Research (PIER) program. The PIER program focuses on a number of energy areas, including Building Efficiency. This research aims to decrease building energy use by developing or improving energy-efficient technologies, strategies, tools, and building performance evaluation methods.
Periodically, PIER will publish informational briefs based on its research, which is often conducted with a variety of organizations with funding from the California Energy Commission’s Public Interest Energy Research (PIER) Program. The briefs are written and prepared by E Source.
PIER recently released a brief about commissioning with a monitor-based appproach. The document, “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 with energy information or energy management systems that are capable of trending building energy use.
