A. Building Retro-Commissioning

The Building Commissioning Association provides a definition of EBCx: "Retro-commissioning is a systematic process for investigating, analyzing, and optimizing the performance of building systems through the identification and implementation of low/no cost and capital intensive Facility Improvement Measures and ensuring their continued performance."

Quantitatively, EBCx projects have been demonstrated to save 10-20 percent of a building's annual utility spend at a simple payback of five months to 2.4 years (M.Chimak)
