There is no better teacher than experience and now NBI has over 280 experiences to share through its new Getting to Zero Buildings Database. The database officially released today offers a dynamic way to find in-depth case studies about high performance and net zero energy (NZE) commercial buildings across North America and beyond. The searchable database includes project-specific information on measured and modeled energy performance, environmental characteristics, design process, finances and more. Members of design and construction teams are listed, as are sources for additional information. Filters allow users to easily identify buildings that have been verified by NBI as zero energy performers—currently 37 confirmed projects with 12-months of measured data--or are working toward that goal.
