Our Approach

We empower individual homeowners by encouraging peer to peer conversations with other homeowners who are doing or have done various energy retrofits.

At the same time, some professionals will participate from time to time, and provide appropriate answers about specific technologies.

Our Story

The idea for this site was born when Rogier F. van Vlissingen did a presentation for professional building managers about how to do a 30-year life-cycle capital budget for energy in order to prevent a lot of false starts and sunk costs.

The questions from the audience made it clear to him that there needed to be a better venue for professional quality advice for homeowner-energy retrofitters.

Meet the Team

Write something about the people who make your business go or your philosophy behind customer service.
Why? Because people want to know who they’re doing business with. It’s a human thing.


Rogier Fentener van Vlissingen

Founder & CEO

One of my most fun periods in the corporate world was a time when I was running a business development department with some engineers and MBA’s, sometimes even engineers with MBA’s.

I always got a kick out of sorting out the wheat from the chaff, and finding the winning projects that truly add value to an organization. For more, see my full bio at:  https://rogierfentenervanvlissingen.me/
