According to Opportunity Finance Network, the financing program is significant not just for its size and scope, but for its use of CDFIs as the delivery vehicle for loans. Through the program, CDFIs specializing in financing energy efficiency improvements can access a pool of $50 million in low-cost loans and $5 million in flexible grants, to support energy efficient building retrofits. Bank of America will select up to 12 CDFIs with the most effective solutions for helping property owners in older buildings to finance energy effiency upgrades.
