Efficient control of ventilation systems needs information on indoor air pollutant concentration. But most of the time, the pollutant concentration is not measured. However, outdoor air pollution forecast models are becoming operational and a relation between outdoor and indoor pollutant concentration may be used to predict pollutant concentration peaks and to infer recommendations to reduce its value . A prediction model of the outdoor/indoor air pollutant transfer, based on experimental data, was obtained using multiple linear regression.
The opportunities offered by National Lottery Funding has focused attention in recent years upon the poor conditions in which much of our written history has to be stored. The documentary record of each county is held in a record office and pressures on local authority spending have meant that often only basic and sometimes inadequate provision for the safe keeping of the documents has been made.
Perceived air quality, symptoms, and perception of the environment were studied in a naturally ventilated office building in which a felt carpet was substituted by linoleum on the first floor and by polyolefine floor tiles, known from previous studies to be a low-polluting floor material on the second floor, while the felt carpet remained unchanged on the ground floor. A panel of 36 untrained subjects occupied the offices on each storey for a period of one hour in a balanced design on a day when normal occupants were absent.
The multi-storey blocks which constitute the main type of building in Greek urban environments, have certain common characteristics. Those characteristics include the overall building dimensions and geometry, internal room dimensions, the materials used both in building construction and insulation, the size and the arrangement of the openings on the facades, the arrangement of the balconies, the position and dimension of the staircase etc.
