When coal-burning gravity furnaces were common, people spoke of feeding the "monster in the basement." The monster seemed defanged when gas and oil replaced coal, but still appeared fearsome. [continue reading]
When air handlers and ducts are located in buffer zones like basements, energy and air quality problems associated with duct leaks--as well as the diagnostic procedures employed to evaluate them--tend to be quite complex and problematic. [continue reading]
Thermal performance in a window is expressed as a "U-value," a measure of heat transfer through it--the greater the heat loss, the higher the U-value. [continue reading]
The sunny Southwest is home to some new and offbeat ideas about building insulation. Plastered straw bales, first used as a building material by settlers in the Sandhills of Nebraska in the 1890s, are now reemerging as an energy-efficient and frugal insulation material. [continue reading]
In the highly competitive home building industry, successful builders learn quickly that to stay in business they must keep construction costs down. Unfortunately, some builders cut costs by skimping on energy features. [continue reading]
Citing recent research confirming that fiberglass insulation loses effectiveness in extremely cold temperatures, Minnesota has adopted a state building code revision which includes a requirement that "all insulation materials must achieve their stated performance at 75deg.F and no less than stated performance at winter design conditions.
