Northeast Sustainable Energy Association

What Northeast Sustainable Energy Association does

Northeast Sustainable Energy Association (NESEA) is a 501(c) membership-based non-profit founded in 1975 and headquartered in Greenfield, Massachusetts. It cultivates a cross-disciplinary community of more than 3,000 architects, engineers, builders, energy consultants, manufacturers, policy makers, students, and facilities managers across the Northeast United States, dedicated to advancing high-performance building, energy efficiency, Passive House, and renewable energy practices in the built environment.

NESEA's product surface is anchored by two annual conferences — BuildingEnergy Boston (typically March, 1,000+ attendees) and BuildingEnergy NYC (typically October) — supplemented by an accredited Pro Tour series of high-performance buildings across the Northeast, a quarterly BuildingEnergy Magazine, a free webinar archive (BuildingEnergy Online), and the BuildingEnergy Bottom Lines peer-business learning program. The BuildingEnergy Access initiative supports women and minority-owned AEC firms through coaching cohorts. Membership is tiered across individual (Student $25, Retiree $55, Standard $75, Emerging Professional $50, Lifetime $1,500) and organizational categories (Academic/Non-Profit $250, Small Business $300, Midsize $600, Industry Leader $1,200), with content committees chaired by volunteer members enforcing a no-greenwashing policy.

Revenue is generated from membership dues, conference and Pro Tour registration fees ($35-$800 per pass), trade show exhibits and sponsorships, donations through a planned giving program (NESEA Sustainability Society), and the 1% for the Planet initiative. Distribution is fully direct, via the NESEA website, in-person events, and an email newsletter; no third-party resellers are used. Partnerships with NYSERDA, Mass Save, MassCEC, USGBC, Urban Green Council, Clean Energy Credit Union, and EastRise provide underwriting, technical content, and member financing benefits.
