Air-Sealing Tips for Efficiency That Lasts // Part 4: Protect Your Air Barrier
This is part 4 of a series that describes how to air seal the most difficult parts of buildings. A service cavity and vented rainscreen promote durable airtightness.
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]
Powered attic ventilators, already suspected of using more energy than they save, can also create excess moisture, structural problems, discomfort, and combustion safety problems for home occupants, according to a recent study. [continue reading]
It is common practice in California to put ducts outside the conditioned space, in attics and crawlspaces. These duct systems are typically 50%-70% efficient due mostly to air leakage and heat transfer losses, while sealed conditioned-space duct installations have efficiencies over 90%.
