Reviews the scientific literature on indoor air pollution. Low-pollution design and construction techniques employed in the Sunnyhill Low-Pollution Research Centre are outlined in detail and suggestions are made on their applicability to new and existing housing in Canada. The study recommends a four-fold approach to the indoor air pollution problem by government and the building industry: A) short-circuit major potential hazards, B) deal with low-pollution housing needs, C) spread and apply present knowledge, and D)foster more research and discussions on regulation.
Operation of an unvented combustion appliance indoors can elevate pollutant concentrations. Under laboratory conditions, oxygen consumption rates and pollutant emission rates of CO, CO2, NO, NO2, HCHO and submicron suspended particles emitted
Most houses in the Netherlands are equipped with gas-fired heaters and cooking appliances, since large amounts of natural gas are available. Carbon monoxide poisonings occasionally occur due to the use of instantaneous water heaters (geisers) that are gas fired. An investigation was carried out to establish the carbon monoxide production potential of geisers under normal conditions of use. The study involved 254 houses: the results indicated that 17% of the geisers produced a carbon monoxide level of more than 50 microL/L in thekitchens where they were located, after 15 min of operation.
Summarizes the state of knowledge about combustion products, surface condensation and mould, formaldehyde and radon, and the guidance currently offered on their control in the UK. Statutory ventilation requirements are outlined and various measurement techniques described.
The purpose of this investigation was to determine the amount of carbon monoxide that may be expected to be produced during normal cooking. The experiment measured carbon monoxide levels, using multiple burners with and without cooking vessels, and the rate of dissipation of the accumulated gasunder various conditions of ventilation.
The Alberta Home Heating Facility has been used over a five year period to attempt to understand the effects of retrofit procedures on the house structure as a whole. The percentage of total energy attributable toinfiltration is calculated, and the influence of furnaces on natural infiltration rates is discussed. Results of blower tests are given for the six modules and compared with measured infiltration rates.
The effects of different ventilation practices on levels of carbon monoxide and nitrogen dioxide from an unvented gas range were studied under controlled conditions at an experimental house near Washington, DC, USA.
Tests were conducted in Ottawa during the winter of 1982/83 to investigate the effects of a gas cooking stove in the kitchen of an energy-efficient two-storey test house. Products of combustion: NO, NO2, CO and CO2, were measured in the kitchen, living room and bedroom in order to relate theinfluence of air infiltration and kitchen hood exhaust operation to the levels of air contaminants. Tests were also conducted, using the enclosed kitchen as a test chamber, to establish the values of emission rate for CO, NO and NO2and of reactivity for NO and NO2.
