Requirements include functional performance testing of HVAC systems, controls, and lighting systems. ASHRAE Standard 90.1 includes similar commissioning requirements for mechanical systems and controls, with more comprehensive requirements in recent editions.<\/p>\n<p>California Title 24 imposes extensive commissioning requirements for most commercial buildings, including acceptance testing for HVAC systems, controls, and lighting. Many California jurisdictions require third-party commissioning for projects exceeding specified sizes or complexities.<\/p>\n<p>State and local jurisdictions increasingly adopt or exceed model energy code commissioning requirements. States like Washington, Oregon, Maryland, and Massachusetts have robust commissioning mandates. Major cities, including New York, Seattle, Boston, and Chicago, require commissioning for certain building types or sizes.<\/p>\n<p>Federal projects must comply with various commissioning mandates. GSA, DOD, VA, and other agencies require commissioning for new construction and major renovations.<\/p>\n<p>Beyond code requirements, commissioning is a condition of many LEED certifications, utility incentive programs, and green building requirements. Even where not required, commissioning delivers substantial value through improved quality, reliability, energy savings, and performance verification.<\/p>\n<p>For guidance on commissioning requirements specific to your location and project type, contact Catalyst Commissioning Group at info@catalystcx.com.<\/p>\n","protected":false},"template":"","class_list":["post-853","faq","type-faq","status-publish","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.9 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Is commissioning required by building codes? - Catalyst Commissioning Group<\/title>\n<meta name=\"robots\" content=\"noindex, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Is commissioning required by building codes? - Catalyst Commissioning Group\" \/>\n<meta property=\"og:description\" content=\"Commissioning requirements vary by jurisdiction, building type, and project scope, with requirements expanding in recent years as energy codes become more stringent.
