Continuous Commissioning (CC®) is an ongoing process to resolve operating problems, improve comfort, optimize energy use, and identify retrofits for existing commercial and institutional buildings and central plant facilities. This process was initiated in 1992 and formally documented in 1999 by the Energy Research Journal and in 2002 by the Continuous Commissioning Guidebook for Federal Energy Managers. The CC process has been very successful for many public facilities. A significant amount of energy savings has been achieved and documented.

Recently, the authors developed the Continuous Commissioning Leading Energy Project process and demonstrated this process in over a dozen projects. This process is named the Continuous Commissioning Leading Energy Project process (CCLEP). Qualified engineering firms can apply the CCLEP process to the private and public sectors, new and existing buildings, and to retrofit and commissioning projects.

This paper presents the CCLEP process and the results from seven completed projects.
