The document discusses green retrofitting of existing multifamily affordable housing properties. It outlines the benefits of green retrofits for property owners, residents, lenders and investors. Some challenges to green retrofits include imperfect information, a lack of comprehensive protocols and limited financing options. The Enterprise Green Communities initiative aims to green all affordable housing within a decade through capacity building, energy audits, and new financing products like add-on loans and bridge loans to fund retrofit projects. Examples of pilots in San Francisco and Ohio that provide loan funds and credit enhancements for green retrofits are also mentioned.
