Report analyzing design heating load sizing methods for superinsulated homes in cold climates and comparing them to the actual energy usage to determine if the building load calculation methodology should be changed for calculating the design heating load of these homes.

Report covering moisture and leakage issues associated with spray foam insulation application to the underside of roof sheathing.

Report about a project that examines implementation of advanced retrofit measures in the context of a large-scale weatherization program and the archetypal Chicago, Illinois, brick bungalow.

Report on heating and cooling air-distribution ducts that are insulated, installed close to the ceiling in a vented attic and covered with attic insulation to minimize energy loss.

Report exploring alternative methods to find long-term solutions to energy loss in 1 ½-story homes to save energy, improve comfort, prevent frost buildup on the underside of the roof deck, and reduce the risk of ice dam formation/reformation.

Report outlining the issues with using existing ducts with a new low-load HVAC system, which reduces throw at supply registers causing decreased mixing of supply and room air, leading to potential thermal comfort complaints.

Report of a field evaluation of four novel roof designs to see how each design would reduce space-conditioned energy use so that the knowledge gained could be applied to the design of new manufactured homes.

Report to understand the long-term moisture performance of unvented roof assemblies with fibrous insulation.
