Model for directing funding to energy projects

Larger businesses may find projects aimed at reducing energy use within a department are hampered by having to find the funding from within existing budgets. Harvard have a loan fund to get around this limitation:

What is the Green Campus Loan Fund?
The Green Campus Loan Fund provides capital for high performance campus design, operations, maintenance and occupant behavior projects. Basic project eligibility guidelines state that projects must reduce the University’s environmental impacts and have a payback period of 5-10 years or less. The model is simple: GCLF provides the up-front capital. Applicant departments agree to repay the fund via savings achieved by project-related reductions in utility consumption, waste removal or operating costs. This formula allows departments to upgrade the efficiency, comfort, and functionality of their facilities without incurring any capital costs.
