Toward Integration of Building Science

OVER THE YEARS, the Department of Energy’s Building America (BA) program has filled a critical gap by funding research on innovations for high-performing homes, both new and existing. But the biggest obstacles to advancing building science are not technological, says Sam Rashkin, the DOE’s chief architect of the Building Technologies Office. The larger hurdle is market adoption, which has several facets, including an inadequate number of skilled professionals. After all, this critical research doesn’t do any good if only a select few people know how to access and implement it.

Advanced Framing Best Practices for a Tighter Thermal Envelope

ADVANCED FRAMING TECHNIQUES that reduce the amount of framing in stud-framed walls improve their thermal performance. There’s more room for insulation, and thermal bridging—the heat transfer that happens through wood framing and extends from the inside surface to the outside surface of the wall—is reduced.

Retrofitting Rooftops: The Overcoat Method

NORTHERNSTAR BUILDING AMERICA Partnership has been investigating the use of an external insulation retrofit approach for existing houses under the “Project Overcoat” label. The overall design intent is to put thermal, air and moisture control layers over the exterior of an existing building, including the foundation, wall and rooftops. The approach uses a peel-and-stick membrane for an air barrier and layers of rigid foam for a thermal barrier to provide exceptional thermal and air barrier alignment and continuity in older homes with simple geometries. NorthernSTAR found the approach worked well for roof retrofits in 1-1/2-story homes, which are difficult to insulate under the roof due to lack of space, and often have serious air leakage problems that can lead to ice dams.

By Klaus Reichardt

ADMITTEDLY, URINALS ARE NOT an everyday topic of conversation. And when it comes to homes and apartments, they almost never enter the discussion. However, that may be changing and changing very soon.

Home urinals, ranging in popularity, have been found in parts of Asia, Europe, Australia, and even in India. However, the trend in the United States is still in its infancy. In addition, the economy, which has severely impacted the housing construction industry, has slowed things down considerably.

Housewrap: What's the Difference?

IT'S A CONUNDRUM: How do you prevent water from entering a building, while also allowing any moisture that does make its way in to escape? This is the formidable task given to housewraps, and increasingly to roof underlayments. Housewrap, a common type of weather-resistive barrier (WRB), is installed between the cladding layer and the sheathing, while roofing underlayments go directly under shingles or other roofing material, forming a second line of defense against the elements.
