Projects + Case Studies

Project profiles and case studies help share the lessons learned for design best practice and energy performance.


Getting to Zero Buildings Database

Find in-depth information about high performance buildings across the United States, Canada, and beyond in the Getting to Zero Buildings Database. Visit database


Advanced Buildings Project Directory

The project directory includes all new construction projects that have used the New Construction Guide or its predecessor, the Core Performance Guide, to ensure maximum energy performance. Profiles and case studies are available for a handful of these projects. Access project directory


Existing Buildings Case StudiesExisting Building Case Study

NBI has developed 11 case studies of deep energy retrofits and renovations in existing commercial buildings that use an average of 50% less energy than the national average–most with an energy use intensity (EUI) of less than 40 kBtus per square foot. These measured performance case studies include motivations, technologies and practices, energy performance, financial information, overall project results and quotes from owner and design teams.  Read case studies


Zero Net Energy Case Studies

A number of the ZNE and ZEC buildings are highlighted in NBI's Getting to 50 buildings database. In addition, we have developed some printable profiles with content excerpted from the Getting to 50 case studies. Read case studies


Daylighting Case Studies

ALG Online’s daylighting case studies provide detailed summaries of how daylighting strategies have been successfully incorporated into both new buildings and renovation projects. Read case studies
