The compliance path for the IECC, found in Section C 401.2, requires that one of the following is met:
ASHRAE 90.1 CLIMATE ZONES CODE
Everyone responsible for the design, maintenance, or ownership of a commercial building continually experiences energy code anxiety during these regular cycles of publication.Īs previously mentioned, most authorities having jurisdiction mandate compliance with the IECC. It includes significant changes affecting the built environment, including the requirement of system commissioning and limits on heated and cooled vestibules. On the other hand, the most recent version of the IECC was published last year (International Code Council, 2018). Next year, a new edition of ASHRAE 90.1 will be published, and the design community will again scramble to adapt to any changes. Within the mechanical section, changes include a mandate for monitoring of large, electric-driven chilled water plants for energy use and efficiency efficiency and rating requirements for dedicated outdoor air systems (DOAS) and performance monitoring for air economizers for air-cooled DX cooling units. This edition includes revisions to the building envelope, lighting, and mechanical directives. (Example, “old” value for offices = 1.3 watts per square foot, “new” value for offices = 1.0 watt per square foot).The most recent version of ASHRAE 90.1 was published in 2016 (ASHRAE, 2016).

Simplified fenestration requirements excluding orientation and window wall ratio.Stringent building insulation requirements.Some of the significant requirements in Standard 90.1-2007 include: Standard 90.1-2007 applies to new buildings and to alterations and additions to existing buildings. Certain buildings that have very low energy use, such as buildings with no heating or cooling, are exempt. Standard 90.1-2007 sets requirements for the cost-effective use of energy in commercial buildings.
