Overcoming Obstacles to Advanced Air Sealing
We all know the basics of energy efficiency. Air seal high in the building, then low, then insulate. Seems simple, right? Stop the air from leaking into or out of the building. Save money. Increase ...
Between 50% and 70% of the energy consumed in the typical American home goes toward heating and cooling, accounting for a large chunk of the total energy bill. [continue reading]
In hilly cities, there are often uninsulated balloon-framed houses on very steep hillsides. This forces insulators to go up 40 feet on ladders to insulate. Meanwhile, tight clearances between homes make the walls truly inaccessible. [continue reading]
The heat wave in Chicago last summer created a great deal of human discomfort and, by many estimates, caused over 500 deaths in three days. The overwhelming majority of these deaths occurred in buildings with indoor conditions that were reported as stifling. [continue reading]
Manufacturers of radiant barrier materials claim that their products significantly cut cooling costs by reducing summertime radiant heat gain through attics and ceilings (see "Conservation Clips: Radiant Barriers Test Well," p. 45). A new study confirms that radiant barriers can indeed conserve cooling energy. [continue reading]
No, they're not living in haylofts. The horses don't knock the houses down for bedding. And the big bad wolf doesn't chase the residents off in search of bricks and mortar. [continue reading]
In the mid-1980s, a Georgia utility became concerned about the large number of attic insulation jobs being done for its energy-efficient home construction program that failed to meet the program's standards. [continue reading]
