747 Wing House
The 747 Wing House was built on the site where existing Duquette structures had burned. Some of the materials from the previous building were used as walkways. The use of the existing pad minimized site grading. The foundation used many of the existing concrete retaining walls but they were rebuilt and reinforced as required to meet new code regulations. This greatly reduced the amount of concrete needed to make the foundation and new walls. Because the wings are only supported in four primary places to the ground, the foundation was further minimized. Both main wings are held up entirely by the four large mounts that the engines originally hung from. By designing the weight distribution on the mounts, it allowed for the outside walls of the building to be made of high efficiency self-supporting glass instead of conventional load-bearing wooden walls. This maximizes solar gain for heating and allows the entire building to be opened to the outside. This also keeps it cool in the summers and minimizes the need for artificial light.
Development of non-profit housing in the United States
Other requirements for HOME funds include the match of funds from other sources, minimum affordability terms for projects, limits on TBRA, and a time limit on when the funds must be allocated and spent by. For every dollar of HOME funds received, jurisdictions must provide a 25 cents match in non-federal sources. Newly constructed rental housing must remain affordable for at least 20 years. For owner-occupied housing (newly constructed and remodeled), acquired rental housing, and remodeled rental housing, the minimum affordability term ranges from 5 to 15 years depending on the amount of funds received in relation to the number of assisted units. Unlike Section 8 vouchers, TBRA is limited to two years and may not be used for project-based rental assistance. Finally, HOME funds must be committed (including reserving funds for CHDOs) within two years and be spent within five years.
