Through strategic funding and partnerships focused on tangible infrastructure, FCI aims to catalyze a sector-wide shift toward zero carbon operations, promoting a future where the visual arts thrive—while contributing to a more sustainable and ecologically conscious world.

Who We Fund

FCI funds nonprofit institutions in the United States and its territories whose primary focus rests in the visual arts. The visual arts includes but is not limited to painting, drawing, sculpture, printmaking, photography, and installations in clay, glass, metal, wood, fiber, paper, film, and mixed media.

Most of our grantees are art museums, nonprofit galleries, archives, noncollecting institutions, art schools, university museums, and artist-endowed foundations.

What We Fund

FCI funds energy efficiency and clean energy generation projects.

FCI meets arts institutions at every stage of the work, through four kinds of grants:

• Catalyst — first actions and stand-alone projects with a quick turnaround
• Scoping — energy audits and assessments that establish a baseline
• Technical Assistance — detailed planning for technically demanding projects
• Implementation — comprehensive capital work addressing a building's environmental impact at multiple levels

Technical Assistance Grants

Technical Assistance grants support projects that have finished initial assessments, and need procurement and financing support for an identified efficiency project. This may include providing designs, specifications, or fees for working with energy services companies (ESCOs) for project support. These grants also support more complex studies or analysis required for pursuing major implementation projects. At the conclusion of a Technical Assistance grant, the applicant should be sufficiently informed to implement a project.
