Many citizens, particularly in nascent green building markets, make suboptimal decisions in the design and construction choices for renovation approaches and new home purchases due to a fear of bank financing. Borrowing sufficiently to bring forward necessary resources to build homes properly both reduces citizens’ “Total Cost of Monthly Ownership” (loan payment plus energy, health and repair costs) while unlocking a critical increase of construction budgets facilitating ownership of the greenest, high-quality homes. Financing Green Homes with the borrower subject to lower monthly operating costs is less risky to banks which provide discounted credit without harming profits. The SMARTER project effectively communicates the benefits of Green Homes to citizens and other key stakeholders to bring a systemic solution to a systemic problem that inhibits the financial industry to design and offer green finance products and the citizens to understand and request them. SMARTER replicates a successful “Green Homes and Green Mortgage” program to 12 new countries, addresses barriers and brings green innovation with relevant research and cluster formation, adapts essential tools for administration and communication, and effectively expands collection of actual energy and financial performance to improve risk analysis with local data. Public investment is leveraged and ambitious green EU targets are supported as banks, developers, and green solution providers all contribute budgets to increase private financing for building exemplary homes. The SMARTER “Green Homes Investment Platform” guides new programs to a suitably ambitious, common definition of green investments and facilitates institutional investment by collaborating with ongoing initiatives including EeMAP and EEFIG; aligning with EC objectives such as “Mainstreaming Energy Efficiency Finance” and advancing the Financial, Technical and Behavioral de-risking championed by “Smart Finance for Smart Buildings".
