UA approach to Commercial Compliance#
Commercial compliance using COMcheck
It is the responsibility of the party using COMcheck to use the most current version of the software. This insures that any updates made within the software are accounted for in your energy model. Either the most current desktop version of COMcheck or COMcheck-Web should be used.
Commercial Building Air Tightness Testing#
All new construction, including commercial buildings, are required to pass a building air tightness test. Testing requirement by building type can be found in the document Air Tightness Testing Different Building Types found further down the page under 'Additional Resources → Building Envelope'. Documentation and reporting of test results is required and must be submitted as part of the final report pack prior to issuance of the C.O..
Commercial Building Commissioning#
All new construction occupied buildings and/or first time tenant finishes with a floor area greater than 15,000 sq ft shall perform commissioning and complete a commissioning report. This commissioning report is to be made available to the building department prior to C.O. upon request.
