The use of urea formaldehyde resins in Canadian houses, the mechanism of formaldehyde releases, health effects, toxicity, carginogenicity, allergic reactions and standards for ventilation are discussed.
In response to employee complaints of upper respiratory and eye irritation, formaldehyde air sampling studies were conducted in two different office environments. The first was in a series of temporary modular buildings with construction simi
In large areas of the Swiss Alps, the high radium content of rocks and soil, which results in high source terms for radon from the ground, may produce considerable indoor levels of radon in dwellings with low air infiltration. During the winter
The prospective study included two groups, a study group, which had retrofitting of their flats, and a control group not exposed to environmental changes in their homes. The results clearly demonstrated a number of positive effects of the replac
New energy conservation policies in New York State are emerging in response to concerns about poor indoor air quality and related public health risks. The evolution of policy has been away from the promotion of energy conservation without explic
The Act (1981.592) on amendments in the Building Ordinance (1959:612) and implementing regulations appertaining thereto in the Building Code come into force on 1st January 1984. The regulations apply only to permanently used houses.
Looks at the separate requirements of ventilation and heat recovery. Discusses the energy cost of ventilation. Gives example calculations for four different situations to show how much saving an air-to-air heat exchanger can provide. Savings depend on ventilation rate, climate and energy price.
A spunbonded polyolefin air infiltration barrier (AIB) was installed immediately beneath the siding of a 5 year old ranch-style house. The AIB reduced the heating energy consumption by 27% during the first heating season and is expected to reduce the heating load by 28% over the remaining life of the house.
Sources of radon and the high levels of radon in many locations and building materials in Sweden are considered. Improvements in energy conservation through the reduction of ventilation rate have lead to very high levels of radon over 1000 BqRnD/m3 in some houses. Recommendations on acceptable levels of gamma radiation on building sites and radon concentration in dwellings are given. It is estimated that there are 30-40,000 dwellings over the Swedish recommended limit of 400 BqRnD/m3 requiring modification.
