The Organization

The Building Energy Exchange provides support for the building industry through energy and lighting efficiency education, technical exhibits, critical research and networking opportunities. Our classes, events and exhibits help create partnerships and broker relationships among design, construction, and real estate professionals within the Greater New York City Region.

We focus on existing, commercially available technologies, systems and processes, help connect legal requirements and best practices to funding, and identify potential barriers to adoption or implementation.

The Building Energy Exchange is a project of Green Light New York, Inc., a nonprofit, tax-exempt charitable organization under Section 501(c)(3) of the Internal Revenue Code. Donations are tax-deductible as allowed by law.
