Case study describing a builder's technology package that achieves energy savings of 50% over standard practice compared to the 2006 IECC.

Case study describing new home construction in the marine climate that achieved 50% savings over the 2004 IECC.

Case study describing a new construction building project of 20 homes that earned HERS scores that represent greater than 50% energy savings in heating and cooling over the 2004 IECC.

Case study describing the elimination of excessive humidity in the attic of a multi-floor, single-family home that was causing condensation and water damage along the roof and eaves.

Case study describing techniques used to prevent thermal bypass in new homes.

Case study describing a stand-off furring strategy that minimizes the physical connections to each existing wall stud, uses spray foam to encapsulate existing siding materials (including lead paint), and creates a vented rain screen assembly to promote drying.
