The Unexpected Energy Benefits of Mechanically Vented Crawl Spaces
The debate on how best to treat crawl spaces has gone on for decades, and the building codes regulating crawl space design have constantly evolved. For a long time the entrenched thinking was to rely ...
Ventilation in the housing stock accounts for one-third to one-half of the space conditioning load, primarily through uncontrolled air leakage. [continue reading]
Many U.S. homebuilders and buyers view compressor cooling as a necessity, even in mild climates. But the widespread use of compressor cooling causes several problems, especially in warmer regions like the West Coast. [continue reading]
The Bigger is Better mentality strikes deep into the heart of the American home. Sure, American consumers will live with low flush toilets; they'll put up with low-wattage lights; but when it comes to the kitchen, they want the culinary equivalent of the sports utility vehicle. [continue reading]
Mold, mildew, failing grout, dislodged tiles, water stains, wet insulation, rotting walls--moisture in bathroom walls causes serious problems. [continue reading]
Researchers at Lawrence Berkeley National Laboratory (LBNL) recently collected blower door data from across the country to analyze the airtightness of the U.S. housing stock. [continue reading]
Exhausting heat and moisture in the summer can keep a house cooler and reduce air conditioning costs. And running a fan whenever someone is cooking will eliminate most water vapor, grease, and combustion products from the kitchen. [continue reading]
Window inlet vents are an alternate way to provide fresh air using an exhaust fan. When the fan is on, it slightly depressurizes the house, causing makeup air to enter through the window vents with minimal heat loss. [continue reading]
Space conditioning is the biggest piece of the residential energy pie, and thermal shell improvement is a homeowner's best opportunity ...
Energy supplies and efficiency in new home construction took an interesting turn when researchers at Oak Ridge National Laboratory (ORNL) ...
