New York City Housing Authority

The New York City Housing Authority (NYCHA), created by urbanist Charles Abrams, provides housing for small and modest profits residents throughout the five boroughs of New York City. NYCHA also administer a citywide Section 8 Leased Housing series in rental apartments. Many of its facilities are known popularly as projects or "developments" and are associated with scarcity and offense. As a safety measure, these premises are patrolled by the NYPD Housing Bureau, with a total of 9 "PSA's," or Police Service Areas that watch each borough except Staten Island which has a divided unit from the Housing Bureau command known as the "SIHU"

NYCHA was created in 1934. At the end of 1935, NYCHA dedicated its first improvement, called First Houses, located on the Lower East Side of Manhattan. The Housing Authority boomed in partnership with Robert Moses after World War II as a part of Moses' plan to clear old tenements and remake New York as a modern city. The majority of NYCHA developments were built between 1945 and 1965.

Basics concept of Structural Insulated Panel

The basic design concept for SIPs is stylish in its simplicity, and offers several advantages for constructing walls and roofs. Bonding the foam core to the stiff outer skins creates a web-and-flange structural strength across the length and breadth of the panel. With the capacity to handle axial, bending, racking, and shear loads, correctly designed and assembled SIPs not only replace conventional framing, but will withstand high wind, and seismic forces.

Insulation capacity is another advantage of Structural Insulated Panel. There is general agreement that SIPs offer better overall air tightness and practical thermal performance than conventionally framed walls. Panel systems offer a dense, uniform and continuous air barrier with few thermal bridges, and no opportunity for internal convection.
