The ground heat exchanger consists of a closed loop in two (House 1) or three (House 2) vertical bores, each approximately 180 feet deep, using two 1-inch-diameter polyethylene pipes with a U-bend at the bottom end of each bore hole (IBACOS

In Pittsburgh, IBACOS
Inc.--which stands for Integrated Building and Construction Solutions--opened up as a research consortium comprised of GE Plastics, Masco Corp., USG Corp., and other building-product suppliers, as well as architectural firms and suppliers of appliances and furniture.
As documented by IBACOS
(2008 and 2010), initial modeling results predicted the Urbana Passive House to achieve 48% source energy savings compared to the Building America Benchmark reference house.
also helps Nevitt track down products and systems that have yet to reach his market on a mainstream scale, as well as to help him and others at Medallion educate subs and crews regarding installation issues and the resulting value of a systems approach to home construction.
To make sure the homes function as designed, IBACOS
is monitoring them for one year.
The duct system was designed by IBACOS
, a building science organization based in Pittsburgh.

ACCORDING to Michael Dickens of IBACOS
(a Building America consortium) in Pittsburgh, it's as soon as the industry grasps true systems integration and how it allows what he terms the "mass customization" of housing construction and delivery.
He worked with IBACOS
(a Building America consortium) to literally re-engineer affordable single-family housing.
And at organizations like the NAHB Research Center and IBACOS
- a research organization funded by a consortium of manufacturers - a host of technical people are trying to improve home building processes.
"As soon as you deviate from a modular dimension, you start a domino effect," says Joe Sowinski, construction programs director for IBACOS
, a Pittsburgh research consortium that does value-engineering analyses for builders.
