New approaches to quality sampling is one of the changes contained in a new guideline on commissioning procedures from ASHRAE.
The American Society of Heating, Refrigerating and Air-Conditioning Engineers has released “HVAC&R Technical Requirements for the Commissioning Process,” also known as guideline 1.1. It covers the technical requirements for the commissioning process described in a 2005 publication on the issue.
Using the two publications will ensure the owner’s performance requirements are met, society officials said.
“The quality-oriented process outlined in the guideline provides improved quality and greater cost effectiveness compared to commissioning as currently practiced by many commissioning providers," said Walter Grondzik, secretary of the committee that wrote the guideline. “One problem with the current practice is that 100 percent checking is performed during the construction phase of the project delivery process, and this checking usually focuses on limited or targeted systems. Quality-based sampling is not used, and so the current approach has limited quality-based random inspection procedures.”
The new guideline has more than a hundred pages of annexes and 25 sample checklists. It costs $69 ($55 for ASHRAE members).
