Commissioning: Stop, Look & Listen

October 1, 2007
Over the last couple months, this column has been about retrocommissioning, commissioning existing building systems that have never been commis-sioned before. There is no question that there is great potential to be realized through a retrocommissioning process, primarily in terms of improved system performance and decreased energy consumption. However, successful retrocommissioning is not something can be accomplished in a vacuum by a commissioning professional; it depends heavily on the building’s O&M staff.

Commissioning: The Least You Can Do

April 1, 2007
Last month, I talked specifically about ASHRAE Guideline 0-2005, The Commissioning Process and its owner’s project requirements document.
