Green Communities Project

Client: Bellingham/Whatcom County Housing Authority

Architect: RMC Architects

Project Size: Three building sites totaling 260,000sf


  • Energy audits
  • Whole building energy model calibration
  • Energy conservation measure (ECM) analysis
  • 90.1 Appendix G Performance Rating
  • Measurement and Verification (M&V)

The Green Communities Project is a major renovation to three public housing authority-owned multifamily towers located in Bellingham, Washington.  Funded by a $9.9 million grant from the U.S. Department of Housing and Urban Development (HUD)/American Recovery and Reinvestment Act (ARRA) stimulus funding, the project’s stated goal is to “facilitate transformational energy efficiency and ‘green’ retrofits to substantively increase energy efficiency and environmental performance of public housing properties and thereby reduce energy costs, generate resident and PHA energy savings, and reduce Green House Gas emissions attributable to energy consumption.”

For this project 360 Analytics started with an in-depth evaluation of existing building performance, including regression analysis of historical utility data, physical building audits, and targeted short-term sub-metering to develop calibrated, baseline energy models. These models were leveraged to evaluate the impacts of individual energy conservation measures, as well as complete a 90.1-2004 Appendix G analysis to demonstrate grant compliance.  Ongoing activities include development and execution of a post retrofit measurement and verification (M&V) protocol and final verification of project savings impacts.
