Infiltration of Outdoor Pollutants
How building airtightness and pollutant characteristics affect the transport of outdoor air pollution into the indoor environment
Last winter, in Oregon's Willamette Valley, a family was spending their first season in a new custom colonial-style house. [continue reading]
Residential energy auditors commonly find problems caused by dust and other airborne particles in forced-air heating and cooling systems. [continue reading]
All houses and apartments need an efficient way to exhaust stale, moist indoor air and introduce outdoor air. [continue reading]
There are few areas of residential construction that are so commonly misunderstood as air movement within and through houses. [continue reading]
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]
