The first of the 50% Advanced Energy Design Guides focuses on small and medium-sized office buildings, and is available for free download. The DOE says the guides provide a practical approach to help architects and engineers design buildings that achieve 50 percent energy savings compared to the commercial building energy code used in many areas of the country.
The guidance also supports President Obama’s goal to reduce energy use in commercial buildings 20 percent by 2020, and will help drive demand for energy-saving products made in the United States, the department says.
The guides recommend ways that designers can choose energy efficient designs for daylighting, building envelope assemblies, and heating and cooling systems, among other technologies. They also recommend commonly available equipment.
DOE says the guides are designed to reduce the time and money that designers would otherwise spend to individually model energy use for high performance buildings. The guides will also inform the development of future commercial building energy codes, the department said.
The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), American Institute of Architects (AIA), U.S. Green Building Council (USGBC), and Illuminating Engineering Society of North America (IESNA) are all helping to develop the booklets.
Three more guides, on large hospitals, medium to big-box retail buildings and K-12 schools, will be released in coming months.
