Green Buildings Open House

It’s the biggest sustainable energy event in the Northeast. In 2011, more than 10,000 people toured 500 homes, businesses, and public buildings showcasing energy-efficient design, systems, and products, as well as renewables. Visitors leave NESEA’s host sites inspired—and ready to upgrade their own homes and buildings.

What is NESEA?

We are the Northeast’s leading member organization of professionals working in sustainable energy, whole systems thinking, and clean technology. Or, as one member puts it, NESEA is “where all the really great geeks are.” Our annual conference and trade show, BuildingEnergy, is the epitome of what we do and who we are. So it seemed like a good place for a few of us to stop and talk about NESEA.
