Greener Than We Thought! Proven Built Green Electricity Savings

Policy makers often rely on green home certification programs to incentivize green building.  However, most certifications are largely based on simulated energy models rather than measured post-occupancy energy use.

 

To better understand the impacts of green building, the Built Green program obtained data for every single-family and townhome built in Seattle in 2014 and conducted an unprecedented study comparing the actual electricity usage of Built Green homes to non-certified homes. To our excitement, we found that not only were Built Green homes meeting modeled expectations, but they were far surpassing them — presenting up to twice as much savings than required and demonstrated by modeling! 

 

The impacts of this large-scale study will help shift the building sector as green home certification is recognized as an effective pathway by policy makers, builders and programs.  The demonstrated energy, cost, and environmental savings of this study’s results present innovative

ways to communicate and maximize the proven benefits of green homes.

 

 

Learning Objectives:

At the end of the session, attendees will be able to actively:

  • Summarize the real-life electricity consumption improvement derived from Built Green certification.

  • Describe the associated cost and environmental savings of Built Green homes.

  • Explain how post-occupancy studies can be leveraged to further green building.

  • Expand the prevalence of green homes by using the results of this study.
