Infiltration of Outdoor Pollutants
How building airtightness and pollutant characteristics affect the transport of outdoor air pollution into the indoor environment
Traditionally, few people have considered gas ovens to be a major source of carbon monoxide (CO), even though all their exhaust products are often vented directly into the indoor air of a residence. Yet unvented space heaters with a similar output of combustion gases have been banned in many states because of indoor air quality (IAQ) dangers inherent in their use. [continue reading]
Heating contractors, inspectors, and energy auditors all have different approaches to inspecting combustion appliances. Combustion problems come in various sizes and shapes, and individual tests may not by themselves prove if the house is actually safe. [continue reading]
Conventional fireplaces are incompatible with new, tighter housing, or with weatherized homes because of their large air requirements and the incomplete combustion products they produce. [continue reading]
The US Environmental Protection Agency (EPA) is developing a model radon control standard for residential construction, with adoption of the standard expected sometime this winter. [continue reading]
While families in southern climates use a considerable amount of energy during the cooling season, conservation programs aimed at reducing air conditioning electricity consumption usually only target homes with central air conditioning, reflecting a general belief that homes with window units can't produce significant savings.

After more than a decade of training and field experience, low-income weatherization crews are substantially increasing the air tightness of homes. [continue reading]
