As measurements are essential for performance assessment, models are essential for design. Both empirical and rational models are being developed for predicting the effectiveness of ventilation for acceptable indoor air quality. In this status report, models for contaminant generation rates, and dilution and removal control are introduced through a simple, one-compartment model.
Contains further papers, reports and conference summaries from the 3rd International Conference on Indoor Air Quality and Climate, 1984, as well as afull list of authors and titles of papers printed in this and the previous volumes.
This report details the development and field testing of a passive sampler system to collect gaseous and particulate contaminants in indoor air and the evaluation of the collected materials for biological effects using a simple bioassay system. The passive sampler-biossay system is a cost-effective objective method for determining indoor air quality.
Discusses the current standards regarding indoor climate produced by ASHRAE, ISO and NKB. The parameters effecting thermal comfort and air quality are outlined.
Compares the guidelines for indoor air quality and minimum ventilation rates outlined in the DIN 1946 and ASHRAE standards. Discusses air quality-controlled ventilation. Outlines the principles and standards governing both natural ventilation and controlled ventilation with heat recovery in residential buildings.
Briefly discusses the major concerns regarding indoor climate raised by the 'Indoor Air 1984' Conference in Stockholm and other such conferences: the need for an international information system on the influence of building materials andventilation of occupant activity, building materials, operation and maintenance; ISO and ASHRAE standards; passive smoking; radon; sick buildings, humidity; ionisation; and ventilation efficiency.
Indoor air quality is regarded as the single most important health issue facing us in the 1980's. The total number of serious health effects related to IAQ in non- industrial buildings have been miniscule compared to the total building stock.
A benchmark study by Geomet Technologies, Inc, is developing data on the air quality effects of weatherizing a home. One effort under this study has bee nhas been an experiment carefully designed to quantify the relationships between the thr
Points out that increased thermal insulation and draughtproofing of homes can increase the risk to health of indoor air pollution. Includes condensation as a pollutant along with associated mould growth. Notes collaboration by Pilkington the glass company and the Timber Research and Development Association plus Laing the housebuilding group, to combat condensation by passive ventilation. Treats sources of indoor air pollution - formaldehyde, asbestos, gas appliances, tobacco smoke, thoron, radon.
Discusses use of a gas sensor developed on the Taguchi principle to measure air quality and control the volume of outside air introduced. Presents case studies of a concert hall and a lecture room, and calculates energy saving.
