Revolving loan funds, often referred to as green revolving funds or sustainability revolving loan funds, provide dedicated funding for schools to invest in energy efficiency or resource efficiency projects while capturing the cost savings from the reduced energy and/or resource use. The high initial cost of many sustainability projects can deter campuses from implementing them, despite the fact that such projects often have long-term cost savings.
There are many possible ways to structure campus sustainability revolving loan funds and similar funds. This resource highlights several different funds that might provide useful models for your own campus.
