Conventional developer-driven projects do not allow room for long payback. It is helpful to run a long-term cost-benefit analysis to estimate the savings after the first ten years of the installation, presenting onsite renewable system as a cost-effective investment to the future occupants. Spec projects can still pursue this credit and install renewable energy with the promise of lower utility bills and future energy freedom to the occupants of the building. The cost can be transferred to the occupant either in the form of higher rent or fees, or an escrow account where the occupant pays monthly dues for the cost of installation over a period of time. It’s also possible to purchase the system on loan and transfer the loan to the future owners. Work creatively to reduce the financial impact and allow as much energy generation as possible.
