In June 2017, DOE made a preliminary determination the provisions of ASHRAE 90.1-2016 are about 8 percent moreĮfficient than the previous version and is expected to make a final determination by the end of 2017. DOE has found ASHRAE 90.1-2013 to be most energy efficient and currently is

Ashrae 90.1 2016 table 5.5 code#

Since 1992, each state has been required toĬertify it has reviewed and updated the provisions of its commercial building code regarding energy efficiency inĪccordance with the most recent version of ASHRAE 90.1 found by the Department of Energy (DOE) to have, as a whole, One reason states often base their commercial building energy code adoptions on the provisions contained in ASHRAEĩ0.1 is because of the federal Energy Conservation and Production Act. Verify applicable energy code requirements with building code officials in the jurisdiction where a project is being Jurisdictions only follow ASHRAE 90.1 for some or all commercial projects. Jurisdictions following IECC generally allow for projects to follow ASHRAE 90.1 if they choose, and some International Energy Conservation Code ® (IECC), which has commercial energy provisions similar to ASHRAE 90.1. Provisions for certain types of construction such as state-owned or state-funded building projects.Īn overwhelming majority of these jurisdictions have commercial energy code provisions based on ASHRAE 90.1 or the Provisions for commercial building energy efficiency though population centers within these states generally haveĪdopted their own mandatory commercial building energy-efficiency codes or have special energy efficiency-related Only Alaska, Arizona, Kansas, Missouri, North Dakota, South Dakota and Wyoming are without statewide mandatory jurisdictions are in areas where commercial construction must comply with statewide commercial energyĬodes. For example, roof systems and skylights are barriersīetween the inside and outside of buildings and consequently subject to the provisions in ASHRAE 90.1. The "building envelope" are elements that form a barrier between the exteriors ofīuildings and the conditioned space on the inside of buildings.

Section 6: Heating, Ventilation, and Air ConditioningĪlthough the standard contains 12 sections, provisions relevant to roof system designers mostly are contained in.

Section 4: Administration and Enforcement.

Section 3: Definitions, Abbreviations, and Acronyms.

The standard's most recent edition contains 12 sections: Roofing-related mandatory and prescriptive requirements. For these reasons, the information that follows is based on complying with The prescriptive-based approach does not require the time and expense to evaluate an entireīuilding or an extensive consultation with mechanical engineers or energy management professionals. Needed to determine the minimum required roof system R-value and related roof system requirements are contained The prescriptive-based approach most often is used because it is relatively straightforward and the information Requirements in one building area but making it up by exceeding requirements in another area.

Styles, or when a building designer wants to use a trade-off approach, such as falling short of energy-efficiency This approach most often is used for especially complex projects, unusual or atypical building The performance-based approach involves analyzing the whole building being considered and determining projectedĪnnual energy costs. Requirements that apply to all commercial buildings and offers a choice between complying with performance- or System designers should be familiar with its roof system-related provisions. In 2016, ASHRAE 90.1-2016 was published and includes updated requirements of which building and roof system designersīecause ASHRAE 90.1 is an option for energy code compliance for commercial buildings in most U.S. Often is an option for roof system designers to demonstrate compliance with applicable energy-efficiency ForĬommercial building projects, ASHRAE 90.1, "Energy Standard for Buildings Except Low-Rise Residential Buildings,"

Roof system designers are responsible for ensuring their designs comply with applicable codes and standards.
