TOPIC: Getting from AEDGs to Zero-Energy Buildings
Buildings account for nearly 40% of U.S. energy use. ASHRAE, IESNA, USGBC, AIA, and DOE have collaborated on a series of Advanced Energy Design Guides (AEDGs) for 30%+ energy savings beyond Standard 90.1-1999. The guides provide prescriptive packages for each climate zone to reach the 30% energy savings. The AEDGs are accepted for points toward LEED-NC certification (instead of simulation). Recent studies have shown that it is possible today to achieve a zero-energy building but they are costly. This presentation provides an overview of the AEDG process as well as examples of packages and case studies from each guide. Also presented are examples of today's zero-energy buildings and a number of activities to aggressively move buildings to substantial energy savings over the next few years.
SPEAKER: Drew Crowley - ASHRAE Fellow and
Distinguished Lecturer
Dr. Crawley leads the development of software for building performance and sustainability at Bentley Systems. Prior to joining Bentley Systems in 2010, he lead the U.S. Department of Energy’s team working to achieve cost-effective net-zero energy commercial buildings by 2025 and was responsible for managing the DOE’s building energy software tools development activities including EnergyPlus and the Open Studio plugin for Google SketchUp.
With more than 30 years of experience in buildings energy efficiency, renewable energy, and sustainability, he has worked in government research and standards development organizations, as well as building software, design and consulting companies. A registered architect, he also has a PhD in Mechanical Engineering on the topic of building simulation as a policy tool from the University of Strathclyde in Glasgow, Scotland.
