Achieving Zero Energy Building Design
Improve your skills in high-efficiency building design with this highly interactive learning program based on the Advanced Energy Design Guide for K-12 School Buildings.
With the trend toward decarbonization increasing interest in net zero carbon buildings and on-site renewable energy, it is essential architects and design professionals understand the process and factors to consider, the best practices and procedures, and where to find the resources to complete a zero energy building design.
The Advanced Energy Design Guide (AEDG) Series has been supporting this effort for over a decade. The guides provide definitions and processes; solution sets by climate zone with a mix of prescriptive and performance-based approaches; guidance on strategies, including whole-building integration approaches; recommended energy targets; and examples of buildings with performance data showing proven techniques and achievable targets.
Adapted from the Advanced Energy Design Guide for K-12 School Buildings and featuring case studies of zero energy K-12 schools, this highly interactive, self-paced learning program offers recommendations, strategies, and resources for achieving zero-energy commercial buildings to help design practitioners improve their skills in high-efficiency building design.
The course was developed by the U.S. Department of Energy (DOE) through the National Renewable Energy Laboratory (NREL), in partnership with the American Institute of Architects (AIA), the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), the Illuminating Engineering Society (IES), and the U.S. Green Building Council (USGBC).
