Fast becoming staples of the green building industry are pre-assembled structural insulated panels, or SIPs, which replace conventional framing and offer greater energy efficiency, reduced lumber usage, and quicker construction. SIPs are polystyrene foam sandwiched between oriented strand boards that provide structural framing, insulation, and exterior sheathing in one piece. They can be used as floors, walls, and roofs and provide much greater energy efficiency than insulation in stud walls with an R-value improvement of 15% to 40%. The oriented strand boards are made from wood of fast growing trees and emit very low levels of urea-formaldehyde. The polystyrene foam can also consist of recycled content.

Follow Philly’s Postgreen as they attempt to build a modern green home for $100,000.
Just over a year ago, Philadelphia developer Postgreen undertook an ambitious project, to build a modern green home for $100,000. Not only are they seeking to shatter the myth that green homes are unaffordable, but they are documenting every step on their site, 100KHouse.com. Located in the New Kensington area of Philadelphia, the house will be a roughly 1,000 square foot two bedroom one and a half bath modern style home - and will not be a prefab; rather it is being built from the ground up according to LEED for Homes guidelines using such affordable energy saving materials as SIPs (structurally insulated panels.)
Documenting the progress of the 100K House are Postgreen President Chad Ludeman and PR Director Nic Darling. Both are convinced that affordable green building is not only possible, but necessary to bring about true environmental change. Their blog posts are not limited to the progress of the 100K House; they write about a range of interesting green topics.
