Discusses sources of formaldehyde indoors, e.g. smoking, formaldehyde resins, and release of formaldehyde from chipboards and foam insulation, and the importance of ventilation in removing excess pollutants. Factors influencing the amount of formaldehyde release include age of materials, temperature, moisture variations, ventilation. Emphasises the importance of quality control, standards and tests such as FTM-1 and FTM-2.
Summary of conference discussions on formaldehyde, including character- ization, sources, measurement techniques, health effects, mitigation techniques and conclusions: 1. Elevated formaldehyde concentrations, higher than 100 ppb, are measured in many indoor environments. Formaldehyde concentrations relate positively with temperature and decrease with the age of the source. 2. Urea formaldehyde bonded products can be improved to such a degree that indoor levels can be reduced to ambient levels if the materials are properly installed and used. 3.
Effects of a coniferous windbreak on electrical energy use in a 66-unit mobile home park in central Pennsylvania were studied during the winters of 1981-82 and 1982-83.
A matched pair of identical mobile homes, one supplied with electric heating and cooking utilities and the other with propane gas utilities, were used to evaluate, over a 14-month period, various factors which may affect indoor formaldehyde c
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.
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
