Free Download

To promote building energy efficiency, ASHRAE and its partners are making the Advanced Energy Design Guides for 50% Savings available for free download (PDF). The 50% Guides offer designers and contractors the tools needed for achieving a 50% energy savings compared to buildings that meet the minimum requirements of Standard 90.1-2004. the 30% Guides offere a 30% energy savings compared to buildings that meet the minimum energy requirements of Standard 90.1-1999.

Overview/Purpose

The Advanced Energy Design Guides (AEDG) are a series of publications designed to provide recommendations for achieving energy savings over the minimum code requirements of ANSI/ASHRAE/IESNA Standard 90.1, the first step in the process toward achieving a net zero energy building which is defined as a building that, on an annual basis, draws from outside resources equal or less energy than it provides using on-site, renewable energy sources. The Guides have been developed in collaboration with these partnering organizations: The American Institute of Architects (AIA), the Illuminating Engineering Society of North America (IES), the U.S. Green Building Council (USGBC), and the U.S. Department of Energy (DOE). The New Building Institute (NBI) participated in the development of the initial Guide.

The original series of Guides have an energy savings target of 30% over 90.1-1999.  Each 30% Guide addresses a specific building type. A complete list can be seen in the published Guides section.

A series of Guides with an energy savings of 50% over 90.1-2004 are now underway. Each 50% Guide addresses a specific building type. Both published and planned Guides can be seen the respective sections.

AEDGTableThe recommendations in the Guides allow those involved in designing or constructing the various building types to easily achieve advanced levels of energy savings without having to resort to detailed calculations or analyses. The prescriptive energy-saving recommendations are contained in a single table for each of the eight U.S. climate zones.

Help in implementing the recommendations of the Guides can be found in an expanded section of how-to tips in the "How to Implement Recommendations" chapter. The how-to information is cross referenced with numbered tips and color-coded climate zone maps. Examples of advanced building designs and technologies are also provided to illustrate the points made and to demonstrate the flexibility offered in achieving the advanced energy savings provided within the Guides. Additional bonus recommendations point out other opportunities to incorporate greater energy savings into the design of the building.

Feedback on the use of any of the Guides is welcomed and encouraged by ASHRAE. Please let us know your thoughts on the Guide itself and/or what impact the recommendations had on your building. How important was the Guide in your energy savings efforts? What energy savings have you experienced as a result of using the AEDG? ASHRAE is always interested in results that can be used as case studies in future publications. Please contact us in Technical Activities with your feedback or technical questions.

Technical Support Documents
All of the 30% Advanced Energy Design Guides have a corresponding Technical Support Document prepared by the National Lab that did the analysis for the development of that Guide.   These documents contain additional details about the analysis and development process.

Preliminary Technical Support Documents have been completed for these building types as exploratory work to determine the types of equipment and design elements that may be needed to reach the 50% energy savings level as compared to Standard 90.1-2004.

30% AEDG Market Assessment
In 2009, ASHRAE commissioned a market survey of its members to assess the market impact of the 30% Advanced Energy Design Guides.   The study focused on the first four published Guides and was intended to compare awareness and usage of the AEDGs, to assess the energy savings impacts resulting from using the AEDGs, and to assess potential improvements that would maximize the Guides effectiveness.  The final report and briefing presentation can be viewed below.

LEED Compliance Path 
The Advanced Energy Design Guides provide a prescriptive compliance path for LEED New Construction EA points.  The specific points available for use of the AEDGs is described in the LEED documentation and may vary by Guide type.  More details are available at the U.S. Green Building Council’s LEED website.
