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]
All houses and apartments need an efficient way to exhaust stale, moist indoor air and introduce outdoor air. [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]
Icicles and ice dams form at the eaves of some roofs in cold regions. Water that ponds behind ice dams may leak into the building since most steep roofs are configured to shed water, not hold back standing water. [continue reading]
While we in the energy conservation business have long been aware of the need for fresh air in a dwelling, we are just beginning to realize how vital it is to assess the quantity and quality of that air. [continue reading]
As part of its new low-income weatherization program for manufactured housing, the Bonneville Power Administration (BPA) is requiring mechanical ventilation in dwellings that receive other standard measures despite the fact that there's no mechanical venting requirement for retrofits of low-income, site-built housing. [continue reading]
Building codes in Washington state and Bonneville Power Administration's specifications for new residential construction require mechanical ventilation systems. [continue reading]
It’s become more apparent over the last five to ten years that the amount of energy we’...
Our new working paper explores healthy home concerns and behaviors among American homeowners and renters. We show that both groups ...
