There are 5.5 million commercial buildings in the U.S. Why are only 700 of them net-zero? We have the technology to slash carbon emissions from commercial buildings, which account for 16% of all U.S. emissions. And retrofitting commercial buildings saves money and energy for building owners.

So what gives?

In this episode, Melissa talks to Dr. Paul Mathew, who studies buildings as a staff scientist at Lawrence Berkeley National Laboratory. He explains the reasons for this "yawning adoption gap" and offers potential solutions. They dig in on:

Simplifying the retrofitting process through new solutions like one-stop shops and energy-as-a-service providers
Finding creative ways to pay for the upfront costs, like green banks and energy service companies
The governments that are testing out new policies like building performance standards.

Also featured in this episode is EcoWorks, a Detroit non-profit that supports energy security, sustainability and retrofits in southeast Michigan.
