HVAC Controls Guide for Plans Examiners and Building Inspectors

 Ensuring compliance with HVAC control requirements is a difficult task, as controls can be difficult to identify on plans or in the building. Yet it is a crucial task. HVAC controls are a key driver of building performance and without compliance and enforcement activities the code requirements may be ignored, overlooked, or misunderstood.

This guide provides an aid that will make it easier to apply the HVAC control requirements found in building energy codes. It addresses requirements defined by the International Energy Conservation Code (IECC), versions 2009 and 2012 and the American Society of Heating and Refrigeration Engineering Association (ASHRAE) Standard 90.1, versions 2007 and 2010, which are common bases for the codes that are adopted by state and local jurisdictions.
