Functional changes and occupant productivity are driving the need to commission existing facilities, so the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) is developing a guideline that addresses the commissioning process.
ASHRAE Guideline 0.2P, The Commissioning Process for Existing Systems and Assemblies, describes the procedures, methods, documentation, requirements and physical activities of the commissioning process for existing buildings, systems and assemblies using the principles developed in ASHRAE Guideline 0-2005, The Commissioning Process.
The proposed guideline is open for public comment from Dec. 6 until Jan. 20, 2014. For more information, visit www.ashrae.orgpublicreviews.
A 2009 study from Lawrence Berkeley National Laboratory suggests a median 16 percent energy savings with a 1.1 year payback for energy-based existing building commissioning. Commissioning also impacts occupant comfort and assists in repurposing buildings. The quantifiable non-energy benefits are often equal to or greater than energy savings.
Guideline 0.2P is a process guideline that is intended to be applied to any type of facility.
