This chapter presents a creation of a more comfortable, productive interior space in our residences, community buildings, etc., and help meet the challenges for increasing affordable housing in all regions. There are many distinct advantages to the planners, designers, and builders/ constructors of affordable homes, and community facilities. A decade ago we would not have been able to provide 1/10 of the resources and contacts for these topics, and meritorious examples of best practices, products, efficient tools, and an array of expert services to propel the desired results. What's more, we illuminate a wide variety of grant, sponsorship, debt, equity, and unconventional financing resources-- from many types of institutions,  private-public, federal, state and local governments, and non-profits We are lucky to be in California,  with our governmental leaders informed and motivated to assist enlargement of affordable -housing, fostering green building, which is one of the largest target sectors for reducing utility consumption, and reducing greenhouse emissions, yet enhancing the quality of life simultaneously.
