The environmental crisis, and hence green building design, revolve around a wide range of issues: habitat destruction, stormwater run-off, air pollution, climate change, and resource use. However,… Read More

Since we use gas hot water heaters for space heating in some of our Building America houses we thought it appropriate that we weigh in on the discussion relating to using gas hot water heaters for… Read More

Air flow measurements were taken for 7.6 m lengths of 12.7 cm through 22.9 cm diameter flexible ducts, with a 15.2 cm wall-cap, at duct pressures of -10 Pa to -120 Pa. Using these measurements and… Read More

A residential attic model, contained in the finite element computer program FSEC 3.0, was empirically aligned with measured attic data from three roof research facilities in Florida and Illinois.… Read More

Energy efficiency measures, such as cool roofs, radiant barriers, interior radiative control coatings, and buried ducts are increasing in popularity and are promoted by energy codes because of their… Read More

This research involved construction of a conditioned test hut in a cold climate (Climate Zone 5A) with multiple side-by-side instrumented roof rafter bays.  This work examined seven experimental… Read More

The purpose of this report is to disseminate the findings from a needs assessment of issues related to attic insulation retrofits in manufactured homes that meet building codes specified by… Read More
