Measurement of combustion products from a gas cooking stove in a two-storey house.

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.

Discussion of 'Radon transport into a detached one-story house with a basement'.

The interpretation of the data presented in the named article (by Nazaroff W W et al, NO 1767) is extended to develop an improved model that can be used to predict radon concentrations in the single family house tested and possibly inothers as well. In particular, a more complete set of low sump activity data has been replotted.

Multizone infiltration measurements in homes and buildings using a passive perfluorocarbon tracer method.

A miniature passive perfluorocarbon tracer system was successfully applied to the determination of air infiltration and exfiltration rates from each zone of a multizoned structure, as well as the air exchange rates between zones inhomes, multiple unit condominiums, naturally ventilated apartment buildings, and large commercial buildings with multiple air-handling systems. Use of the multizone technique in indoor air quality assessments and air-handling system stratification studies appears to be quite feasible with the availability of this measuring system.

Indoor air quality modeling: compartmental approach with reactive chemistry.

Data on indoor/outdoor pollutant and tracer concentrations were collected during different periods in 1981 at a residence in Newton, MA. 

Indoor radon source fluxes: experimental tests of a two-chamber model.

Modelling houses as two coupled chambers, namely, the living area and basement, predicts more accurately the total indoor radon source flux from building materials and geology than a one-chamber model in houses with disparate radon concentration

Basic material for the instruction of occupants of homes. How, when and where to use your windows.

Airtightness measurements were carried out in ten typical Dutch dwelling complexes. In each complex four homes were measured. The IMG calculation model was used to calculate expected ventilation for these dwellings. Results of a survey of 1500 occupants on use of ventilation are given. The ventilating behaviour in 610 homes was studied in greater detail. 210 of these had some form of mechanical ventilation. Ventilation requirements are given for individual rooms.

Indoor radon levels: effects of energy-efficiency in homes.

The expectation of elevated 222Rn levels in modern homes that have low air interchange rates with the outdoor air led to a survey of both conventional and solar homes in northeastern New York State. As a group, homes that are more airtight ha

Humidity, condensation and ventilation in houses.

Contains articles on rain penetration and moisture damage in residential construction, moisture sources in houses, control of surface and concealed condensation, and ventilation of houses. Illustrates the various types of condensation problems that may occur, explains the active processes involved in some of these problems and discusses in detail the principal factors surrounding these phenomena i.e. sources of moisture, choice of construction detail, and current ventilation practice.

Indoor formaldehyde levels in houses with different ventilation strategies.

This paper discusses the indoor formaldehyde levels in two groups of houses. With the exception of the heating and ventilation systems, the house construction, formaldehyde sources and occupancy were similar for the two groups, One group (A) used electric baseboard convective heaters for space heating and semi-ducted heat recovery ventilators (HRV) for supplying outdoor air and exhausting indoor air , The second group (B) had electric forced-air furnaces with a ducted air supply to every room, Outdoor air was drawn in via a connection to the return air ductwork.

Mechanical ventilation system requirements and measured results for homes constructed under the R-2000 super energy-efficient home program.

The R-2000 Super Energy-Efficient Home Program is a cooperative industry/government initiative sponsored by Energy, Mines and Resources Canada (EMR) and delivered by the Canadian Home Builders Association. The program supports building industry development, training of builders and the construction of energy-efficient houses incorporating high levels of insulation, a well sealed air barrier and mechanical ventilati on systems with heat recovery. In 1983, with assistance from the Buildings Energy Conservation Sub-Committee (B.E.C.S.
