Building Commissioning

On January 1st, 2016, the Texas Comptroller’s State Energy Conversation Office (SECO) adopted the 2015 International Energy Conservation Code (IECC) statewide for commercial construction. The mandatory update went into effect on November 1st, 2016.

The 2015 IECC represents a significant change from the 2009 IECC which was the previous prevailing energy code across most Texas jurisdictions. All building lighting controls must now be commissioned. Building mechanical systems in excess of 480,000 btu/h (40 tons) cooling capacity or 600,000 Btu/h combined service water-heating and space-heating capacity must also be commissioned. Many local jurisdictions (eg. San Antonio and Austin) have well established protocols in place for documenting required commissioning. Criterium-Williams Engineers is an experienced commissioning service provider well versed in the nuances of different system designs.

Building envelope commissioning is not explicitly required by the 2015 IECC. The 2015 IECC does, however, contain mandatory requirements for demonstrating effective envelope performance. The building envelope is the most failure prone component of the building and an effective envelope commissioning program can pay dividends when errors and defects are caught early in the construction process. Criterium Engineers has experience acting as the envelope commissioning agent on a wide variety of projects across the country. We draw upon this vast experience when providing local envelope commissioning services. 

As licensed Professional Engineers certified in building commissioning, we meet the requirements established by local jurisdictions to serve as the commissioning agent. As an independent commissioning authority, we provide an unbiased perspective and additional layer of quality assurance.
