Leaders in Energy Efficiency Financing (LEEF)



The Leaders in Energy Efficiency Financing (LEEF) Network was a regionally-focused program of the Sustainable Endowments Institute (SEI). In 2011, SEI launched the Billion Dollar Green Challenge to encourage nonprofit institutions to invest a combined total of one billion dollars in self-managed revolving funds to finance energy efficiency improvements. Recently, the Barr Foundation helped SEI establish the LEEF Network in Massachusetts, a program specifically focused on implementing green revolving funds (GRFs) in higher education, healthcare, municipalities, and non-profits. SEI received additional support from The John Merck Fund to include Maine, New Hampshire, Rhode Island and Connecticut. Vermont was covered under an existing program partnership with the Vermont Energy Investment Corporation.

LEEF functioned as an information distribution system focused specifically on the implementation of GRFs at institutions in Massachusetts and throughout New England. GRFs provide a financial structure that facilitates energy-efficiency upgrades and retrofits by helping to offset higher first costs and treating efficiency projects as an investment rather than an expense. SEI has published reports and case studies that provide detailed information on green revolving funds.

What We Do


LEEF provides access to cross-sector collaboration and peer-to-peer contact through networking and information exchange. We offer presentations that can be tailored to fit the needs of your organization, and are available for strategy sessions with working groups and committees. The LEEF program also provides hands-on support for developing documentation and proposals for GRF implementation. All participation and services of the LEEF Network are gratis.

Regional Workshops


LEEF will hold regional workshops on GRF topics, including seed sources of capital, types of projects financed, options for administering and tracking, and financing investments in renewable energy. Workshops will examine the GRF structure in detail and will provide an opportunity to share ideas, test strategies, brainstorm, and learn from your peer’s best practices.

New England Board of Higher Education


The Leaders in Energy Efficiency Financing Network recently announced a new collaboration with the New England Board of Higher Education (NEBHE). NEBHE will help LEEF broaden its outreach efforts as well as sponsor regional workshops and webinars.

Founded in 1955 by six visionary New England governors, NEBHE brings together leaders of education, higher education, government, business and labor to forge partnerships and advance ideas that enhance the economy and quality of life in the six-state region and around the world. NEBHE works to increase the education opportunities for New England residents and to promote collaboration among the region’s colleges and universities to expand access, success, affordability and the economic impact of higher education.
