Notes the trend to installing windowless kitchens, bathrooms and W.C.s in the internal zones of dwellings. Describes a research project to measure for internal kitchens the energy consumption and emission of equipment, the total daily energy consumption, air temperatures, air humidity values during cooking, comfort and air speed. Illustrates the test kitchen and gives the results of measurements of around 100 days of simulated operation for a household of four. Notes the consequences for recommended normal and peak ventilation rates.

Describes the aims, methods and results of a preliminary study into radon in Swiss house carried out 1981/82. In the winter of 1981/82 three Karlsruhe type passive radon dosimeters were exposed in each of 123 dwellings in selected regions of Switzerland and the results evaluated in summer 1982. Thedosimeters were normally placed in the cellar, living room and a bedroom. Gives figures for the average radon concentrations in the rooms. Notes marked regional differences caused by different geological formations.

States that with double and triple glazed windows the air flow through the joints reduces the transmission heat flux. This has the effect of lowering the heat load and in particular the annual heat energy demand. The same phenomenon occurs when the windows are covered with shutters at night. Provides calculation equations.

Describes the housing development comprising 224 apartments in three courtyards built in 1908. Provides a detailed description of the thermal modernisation measures and their monitoring from 1974 to 1982, permitting the systematic observation of the situation before, during and after modernisation. The present report concentrates on the measurements carried out from June 1980 to the end of May 1982. Four of the apartment buildings each containing 10 apartments were treated as test buildings with experimental energy conserving installations and constructional measures.

Provides the results of tests into tracer gas concentration decay carried out in 15 Belgian apartments (Concours CHT) in 1982 to determine the rates of air infiltration. The tests formed part of a research programme which included pressurisation

Presents the abridged text of the 11 papers given at the seminar.

Heat loss data for dwellings is given. Ways of reducing heat loss are considered.

Wind pressures on three Navy buildings at the Kanehoe Marine Corp Air Station, Hawaii were measured. Indoor and outdoor variables were also measured including temperature, dry bulb, wet bulb, relative humidity, wind speed, and wind direction. Pressure measurements were carried out using Validyne DP103 pressure transducers, and a static pressure probe. Natural ventilation is estimated 1. by combining window areas and pressure coefficients with wind speed and 2. using the LBL infiltration model.

Shows the results of a study of the effects of turbulence upon ventilation. Controlled fluctuating air flows were directed upon openings in the side of acube simulating a building. The relationship between the turbulent characteristics of the air flow and the ventilation rate in the building modeare examined. Mean windspeed and the turbulent velocity and intensity of the air flow were measured with a thermocoupled anemometer. Resulting ventilation rates were measured by means of tracer gas decay, using CO2 as the tracer and an infra red analyser to monitor the decrease in concentration.

Discusses the symptoms and compaints of the occupants of unhealthy buildings. Compares the availability and sensitivity of building sensors to human sensitivity for the full fange of indoor air contaminants. Refers to the difficulty of assessing pollution using occupant questionnaires. A simple equation for determining contaminant concentration is presented and ventilation standards are discussed.
