Our Work

The Building Energy Exchange (BE-Ex) connects New York City’s real estate and design communities to energy and lighting efficiency solutions through education, exhibitions, technology demonstrations, and research.

Come visit our space in downtown Manhattan, open 9 am – 5 pm Monday through Friday.


Ranging from topical forums to our Green Light Training series covering lighting controls, upgrades, and retrofits, BE-Ex programs convene diverse voices and deliver up-to-date, in-person education to the public.


BE-Ex reports compile research and resources to help building stakeholders synthesize salient topics in the energy efficiency sphere.
