A wide range of incentives are currently available for making sustainable building more affordable to both developers and homeowners. We have tried our best to compile and categorize these incentives, but our lists are by no means comprehensive. DSIRE, the U.S. EPA, and Energy Star all have great resources as well, and are helping to aid in the search for financial incentives.
DSIRE, the Database of State Incentives for Renewables & Efficiency, connects to a variety of local, state, federal and utility incentives that encourage the use of renewable or efficient energy. DSIRE is a nonprofit project funded by the U.S. Department of Energy through the North Carolina Solar Center and the Interstate Renewable Energy Council. It is consistently regarded as one of the best sources for locating financial incentives. In addition to financial incentives DSIRE also contains rules, regulations, policies and programs related to the fields of renewables and efficiency.
The U.S. Environmental Protection Agency links to many of the funding sources available at the state and local levels for homeowners, industry, small businesses, government organizations and nonprofits in the form of grants, tax credits, loans and other sources.
ENERGY STAR connects consumers, home builders and others to federal tax credits available for using energy-efficient products and techniques. The site is well-maintained and organizes funding opportunities by materials utilized, such as doors and windows, roofs, HVAC, Solar Energy systems etc.
