For controlling and for setting ventilation standards to maintain acceptable indoor air quality, it would appear to be of greatest importance to determine the strength of relationships between contaminant concentrations on one hand and different rates of ventilation and how these rates are expressed on the other.
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.
Measures of a number of ventilation parameters and of a number of pollutants from 21 locations furnished data for evaluating interrelations among commonly used descriptors of ventilation as well as their relation to frequently measured indoor gaseous and particulate pollutants.
This investigation looks at sensory (odour, irritation) and physical criteria for ventilation requirements, paying particular attention to the difference between smoking and nonsmoking occupancy in a well-controlled environmental chamber.
Particulate and gaseous emissions from indoor combustion appliances.and smoking can elevate the indoor concentrations of various pollutants. Indoor pollutant concentrations resulting from operating one or several combustion appliances, or from sidestream tobacco smoke, were measured in a 27m3 environmental chamber under varying vent ilation rates. The combustion appliances investigated were gas-fired cooking stoves, unvemed kerosene--fi red space heaters, and unvented natural gas-fired space heaters.
Two bi-level houses in Gaithersburg, Maryland, USA, of identical design and construction were studied to determine the relationships among air exchange, energy consumption, and indoor pollutants. The experimental house was retrofitted and equip
Gives basic facts about indoor air pollution for homeowners. Lists common indoor air pollutants and guidelines for generally acceptable levels of selected air contaminants. Some suppliers of measurement equipment are mentioned.
The effects of operating unvented appl i ances and opening windows on indoor pollutant levels and air exchange rates are being studied under the sponsorship of the Gas Research Institute. The study is being conducted i n an instrumented, well-characterized bilevel house located near Washington, D.C. Air leakage due to window openings is characterized by pressurization measurements and the air exchange increment is characterized through tracer gas measurements. Two unvented space heaters, one radiant and the other convective, are operated singly and in combination with a gas cooking range.
