Our Story

Formerly the Open Green Building Society and Regenerative Applications Inc., we became OPEN in 2018 to streamline our focus towards software tools that promote the market adoption of high performance products and best practices in energy management.

Our Approach

We believe that decisions informed by data and knowledge of industry trends are better decisions, and that regulatory, financial, social, and environmental objectives can be aligned as a result.  To achieve this, OPEN:

  • develops low-barrier tools that provide attractive, accessible, and actionable information; and

  • strives to effectively balance competition and sector building in designing our sustainable revenue model.
