Overview of PIER-Funded Existing Building Commissioning and Diagnostics Research

The California Energy Commission's Public Interest Energy Research (PIER) Program supports research and development that helps improve the quality of life in California by bringing environmentally safe, affordable, and reliable energy services and products to the marketplace. The PIER Program awards up to $62 million annually and has funded some of the most promising energy research in the U.S. The PIER Buildings program area seeks to decrease building energy use through research that develops or improves energy efficient technologies, strategies, tools, and building performance evaluation methods. This paper summarizes the accomplishments of projects within the PIER Buildings Program related to existing building commissioning and diagnostics between 1999 and 2003
