| The ASHRAE Advanced Energy Design Guides (AEDG) are a series of publications designed to provide AEDGBookrecommendations for achieving energy savings over the minimum code requirements of ANSI/ASHRAE/IESNA Standard 90.1-1999. 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 only in the development of the Advanced Energy Design Guide for Small Office Buildings.
The initial series of guides have an energy savings target of 30% which is the first step in the process toward achieving a net zero energy building - 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. Each 30% Guide addresses a specific building type. Additional guides for existing buildings and at 50% energy savings towards a net zero energy building are also planned.
ANSI/ASHRAE/IESNA Standard 90.1-1999, the energy conservation standard published at the turn of the millennium, provides the fixed reference point for all of the 30% Guides in this series. The primary reason for this choice as a reference point is to maintain a consistent baseline and scale for all of the 30% AEDG series documents.
AEDGTableThe recommendations in the 30% Guides will 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. All of the energy saving recommendations for each of the eight U.S. climate zones are contained on a single page, thus facilitating the 30% Guide's use. Additional recommendations point out other opportunities to incorporate greater energy savings into the design of the building.
Help in implementing the recommendations of the 30% Guides can be found in an expanded section of tips and approaches in the "How to Implement Recommendations" chapter of the 30% Guides. To further facilitate its use, the 30% Guides cross-reference the how-to information with numbered tips and color-coded climate zone maps. Examples of advanced building designs are also provided to illustrate the points made and to demonstrate the flexibility offered in achieving the advanced energy savings provided within the 30% Guides.
The use of the guides provides a prescriptive path to achieving LEED v2.2 Energy & Atmosphere credits for New Construction and Major Renovation projects. USGBC's Leadership in Energy and Environmental Design (LEED) Green Building Rating System? provides a roadmap for measuring and documenting success in the design, construction, and operation of high performance green buildings. The LEED for New Construction focus primarily on office buildings, but USGBC is also developing LEED Retail for New Construction and LEED for Schools. |
