Using ASHRAE Design Guide Can Earn LEED-NC Credits

Latest News > Green Building News

HVAC professionals and other designers who use, “The Advanced Energy Design Guide for Small Office Buildings,” can now earn credits toward certification in accordance with the Leadership in Energy and Environmental Design (LEED) green building rating system of the U.S. Green Building Council (USGBC).

The design guide was developed by a group of professionals drawn from ASHRAE, the American Institute of Architects, the New Buildings Institute, the Illuminating Engineering Society of North America and the U.S. Department of Energy.

The design guide is included in LEED-NC 2..1, and the most recent revision 2.2, of the rating system for new construction and major renovations, as a prescriptive compliance path to achieve LEED-NC Energy and Atmosphere Credit 1, Optimize Energy Performance (EAc1) credit, according to ASHRAE.

(You can also earn LEED certification credits in the Energy & Atmosphere, Indoor Air Quality and Innovation and Design Process sections of the LEED-NC rating system by using the Taco LoadMatch® System. For a detailed explanation, please download, “LoadMatch Systems & Green Buildings.” )

LEED-NC EAc1 is intended to reduce environmental impact associated with excessive energy use by awarding LEED credit to buildings that achieve increasing levels of energy performance above the ANSI/ASHRAE/IESNA Standard 90.1 – 1999.

The guide establishes a previously unavailable prescriptive compliance path and enables small office design teams to earn LEED-NC EAc1 points without incurring the costs associated with whole building energy simulation. Small office buildings that successfully demonstrate compliance with the guide will be awarded 4 LEED EAc1 points.

“The design guide series is intended to provide prescriptive guidance to bring us 30% closer to a net zero-energy building, meaning those that use equal or less energy than they produced on an annual basis, explained ASHRAE President Lee Burgett, P.E. “Our goal is to provide the technical resources needed to assist the HVAC&R industry in creating the most sustainable buildings possible,” he added.

“The Advanced Energy Design Guide for Small Office Buildings” is available from ASHRAE at $59 for non-members and $47 for members. For more information and ordering go to:
