Significant contributions to procedures used in the measurement and analysis of buildings energy use have been made by the program. Measurement and analysis of energy use is critical to improving energy efficiency, as indicated by the management maxim, "You can't manage what you can't measure."
Energy (and power) monitoring in buildings is conducted for a variety of purposes. Some of these are: utility planning, assessing the energy performance of new buildings or building systems such as lighting or heating-cooling systems, verification of retrofit savings, assessing public policy, and diagnosing specific problems in buildings. Monitoring is presently used by many professionals to guide improvements in building energy performance.
Significant recent work on measurement and verification (M&V) of the performance of energy and water efficiency projects has been conducted. The web site of the the International Performance Measurement and Verification Protocol (IPMVP) should be consulted by all persons interested in this topic (http://www.ipmvp.org).
There are several building energy measurement guides and standards that have been developed by professional societies over the past several years, all with the direct help of this program:
These guides provide professionals important information they can use in measuring and analyzing energy use and energy efficiency improvements in buildings. Additional information is provided in research reports, which provide more detail than is possible in the national-level standards and guides:
For the commercial sector, two separate documents cover energy measurement and energy analysis:
In addition, special reports on the use of energy management and control systems (EMCS) for monitoring energy use in buildings were completed:
Overall, the program has supported many major contributions to guidance for professionals on building energy measurement and related analysis issues.
