Energy-Saving Strategies - Think Again
The rules regarding home energy savings are changing. New technologies and shifting realities are showing us that many of the old energy-saving dictums are now obsolete. If, for instance, you look at the top energy-saving ...
When something must be done about an old or inefficient heating system, the challenge can be daunting. The decision will affect comfort, energy costs, and the air quality and safety of a home for years to come. [continue reading]
In the Northwest, energy losses in forced-air systems average 25%-30% in electrically heated homes, with some homes being significantly worse. [continue reading]
Although the thermal shell of the typical mobile home has changed radically over the last 30 years, the air distribution system has not. The walls have gone from 2 x 2 framing with an R-4 fiberglass batt to 2 x 4 or 2 x 6 walls with a high-density R-21 batt (codes vary from state to state). [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%. O [continue reading]
Homeowners may continue to enjoy their single pane glass windows and gain energy efficient advantages for up to 80% ...
Last summer, DOE issued new efficiency standards for furnace fans, which are a little-known energy hog that may be lurking ...
