Case Studies

Case study describing an alternative ground source heat pump (GSHP) cold-climate application in an attempt to reduce the installation cost of the ground loop portion by containing the entire loop beneath the basement slab.

Case study describing the performance of a small-diameter, high-velocity heat pump system compared to a conventional system in two identical new construction triplex townhouses.

Case study describing a DOE Building America 2013 Top Innovation community-scale project where solar water heaters generated enough hot water per year to recoup the cost of the system within 4 to 6 years.

Case study describing a DOE Building America Top Innovation on quality management tools for builders, trades, and designers to help eliminate mistakes that would require high-cost rework.

Case study describing a 2013 DOE Building America Top Innovation about construction of net-zero energy ready homes, by several builders working with various DOE Building America research partners including Steven Winter Associates, Building Science Corporation, Home Innovation Research Labs, IBACOS...

Case study describing analysis of pre-retrofit utility data from 1,166 houses to help determine energy savings on a community-scale.

Case study describing ductwork installation.

Case study describing application of exterior rigid foam insulation on a foundation system.

Case study describing installation of exterior rigid foam insulation on a slab foundation.

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.

Case study describing lessons learned from production builders who install efficient hot water delivery systems.

Case study describing innovative technologies, construction techniques, products, and design trends in new home construction.
