Zero Energy Case Studies
NZEC Zero Energy Residential Buildings
Inventory and Case Studies
The only centralized source of zero energy projects for the U.S. and Canada
NZEC conducted a massive effort to inventory and document zero energy projects from across the continent. This collective impact initiative provides an invaluable resource for sharing knowledge and catalyzing the market. We continue to build upon the inventory and database, and member and industry contributions are key to the quality and success.
This effort consists of two components:
1. Inventory of projects and report of findings and trends.
To contribute your project to our inventory, please fill in our online form (it’s short – about 1 minute per project).All residential projects can participate — single- and multifamily, new and retrofit, and whether completed, under construction, or just in the design or planning stages. Please report all of them.
Click below to enter a NEW project (one you have not entered before).
Click below to UPDATE a project you have reported before.
2. Case study database with more detailed information about each project, including technologies, design, marketing, and costs.
This easy-to-use, comprehensive database was developed in partnership with NESEA. To submit your project to our database, go to the NESEA website and complete the online forms with the appropriate information. Detailed instructions are here. Once we have reviewed your project, we will contact you directly and publish the case study.
