30% Energy Savings Target
ASHRAE

The ASHRAE 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 90.1-1999.  The guides have been developed in collaboration with these partnering organizations:  The American Institute of Architects (AIA), the Illuminating Engineering Society of North America (IESNA), 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.
