Two new units, the olf and the decipol, are introduced to quantify air pollution sources and air pollution perceived by humans indoors and outdoors. The olf is introduced to quantify pollution sources. One olf is the emission rate of air pollutants (bioeffluents) from a standard person. Any other pollution source is quantified by the number of standard persons (olfs) required to cause the same dissatisfaction as the actual pollution source. The olf unit is analogous to lumen and watt for light and noise sources.
There are reputed to be only ten examples of the thermal manikin (a computerized doll) in the world at present. Here, the author discusses their potential in microclimate research, and describes experiments with a thermal manikin at the Hungarian Institute for Building Science (ET/) to identify the quality of indoor comfort conditions. One study revealed that the correct heating system would yield better results than extra thermal insulation.
Surface condensation and mould affect about 15 percent of the UK housing stock. This paper reports BRE studies in occupied dwellings on the effectiveness in various situations of a range of remedial measures, which included improvements to thermal insulation and heating, and the provision of extractor fans and dehumidifiers. The flats and 2-storey houses involved were all of traditional construction with brick walls and pitched roofs.
