A microprocessor-controlled, five point, all-teflon sequential air sampling system interfaced to a continuous formaldehyde analyser, the CEA model TGM 555 Air Monitor which uses the pararosaniline colorimetric method was used tomeasure the seaso

Due to better insulation and improved airtightness of doors and windows, the supply of fresh air entering a room has been greatly reduced. This in turn causes an increase in the amount of pollutants emitted by different insulation and building materials. Measurements of the formaldehyde concentration in newbuildings have shown that the admissible limits are still exceeded even after a year. Stricter regulations limiting the emissions of pollutants are therefore urgently necessary.

During the last fifteen years Urea-Formaldehyde (UF) bonded particle board, medium density fiberboard and plywood have replaced whole wood as a construction material for flooring, wall panelling cabinet work and furniture. At the same time,

Evaluates the space-conditioning energy conservation potentials of landscapes designed to ameliorate building microclimates. The physical bases for vegetative modifications of climate are discussed, and results of past study of the effects of vegetation on space-conditioning energy consumption in buildings are reviewed. The state-of-the-art of energy-conserving landscape designs is assessed and recommendations are presented for further research. Landscaping mobile houses and single family dwellings is considered.

Requirements for new buildings including large residential buildings are given and cover illumination, exterior envelope, heating, ventilation and air conditioning, service water heating, transportation, freeze protection and energy management. Systems analysis for energy conservation design is discussed. These recommendations are compared with ASHRAE/IES standard 90A-1980. 

Spatio-temporal measurements of a fluctuating pressure field acting on the side faces of a square prism of finite height in boundary-layer flows are presented for a zero degree angle of attack. Two typical neutral atmospheric flow conditions

Describes methods of predicting concentration levels of indoor air pollution in a variety of residences by using residence air infiltration rates, residence volumes, and source terms, and by making assumptions about occupant lifestyle and poll

Measurements of radon and radon daughters in 11 buildings in five states, using active or passive solar heating showed no significant increase in concentration over the levels measured in buildings with conventional heating systems. Radon levels in two buildings using rock storage in their active solar systems exceeded the U.S. Nuclear Regulatory Commission's 10 CFR 20 limit of 3 pCi/l for continuous exposure. In the remainder of the buildings, radon concentrations were found to be at levels considered to be normal.

Results of air quality measurements are presented for a group of low-leakage houses located in Saskatoon, Saskatchewan. A total of 46 houses were tested for formaldehyde, nitrogen dioxide, radon, and humidity levels. The median level of formalde

Describes the different types of monitoring and sampling techniques that can determine the radiation burden of the general public from radon and its decay products. This is accomplished by measuring the range and distribution of radon and rad
