air quality

Quality requirements for the indoor climate. Kvalitetskrav til inneklimaet.

Discusses the current standards regarding indoor climate produced by ASHRAE, ISO and NKB. The parameters effecting thermal comfort and air quality are outlined.

People and indoor air. Mensch und Raumluft.

Compares the guidelines for indoor air quality and minimum ventilation rates outlined in the DIN 1946 and ASHRAE standards. Discusses air quality-controlled ventilation. Outlines the principles and standards governing both natural ventilation and controlled ventilation with heat recovery in residential buildings.

Indoor climate and air quality. Inneklimat och luftkvalitet.

Briefly discusses the major concerns regarding indoor climate raised by the 'Indoor Air 1984' Conference in Stockholm and other such conferences: the need for an international information system on the influence of building materials andventilation of occupant activity, building materials, operation and maintenance; ISO and ASHRAE standards; passive smoking; radon; sick buildings, humidity; ionisation; and ventilation efficiency.

Indoor air quality: problem of the 80's.

Indoor air quality is regarded as the single most important health issue facing us in the 1980's. The total number of serious health effects related to IAQ in non- industrial buildings have been miniscule compared to the total building stock.

The dynamics of indoor air quality.

A benchmark study by Geomet Technologies, Inc, is developing data on the air quality effects of weatherizing a home. One effort under this study has bee nhas been an experiment carefully designed to quantify the relationships between the thr

Pollution begins at home.

Points out that increased thermal insulation and draughtproofing of homes can increase the risk to health of indoor air pollution. Includes condensation as a pollutant along with associated mould growth. Notes collaboration by Pilkington the glass company and the Timber Research and Development Association plus Laing the housebuilding group, to combat condensation by passive ventilation. Treats sources of indoor air pollution - formaldehyde, asbestos, gas appliances, tobacco smoke, thoron, radon.

Air quality control - measurements and experience.

Discusses use of a gas sensor developed on the Taguchi principle to measure air quality and control the volume of outside air introduced. Presents case studies of a concert hall and a lecture room, and calculates energy saving.

Environment and Power: Home weatherization and indoor air pollutants.

A booklet for consumers explaining the effects of house-tightening measures on pollutant levels. It also provides a guide to detecting and controlling pollutants commonly found in homes.

Indoor air pollution and housing technology.

Reviews the scientific literature on indoor air pollution. Low-pollution design and construction techniques employed in the Sunnyhill Low-Pollution Research Centre are outlined in detail and suggestions are made on their applicability to new and existing housing in Canada. The study recommends a four-fold approach to the indoor air pollution problem by government and the building industry: A) short-circuit major potential hazards, B) deal with low-pollution housing needs, C) spread and apply present knowledge, and D)foster more research and discussions on regulation.

Assessment and control of indoor air quality in a super-insulated, retrofit house.

A single family residence in St. Paul, Minnesota, constructed in 1957, was retrofitted in 1983. This resulted in approximately 50% reduction in annual heating consumption compared to the average consumption over the previous three years. However, the occupants complained of poor air quality. Measurements indicated that total particulates, CO, CO2, relative humidity, and temperature were at levels of some concern; NO2, radon and formaldehyde concentrations were not significant.
