Reports wind tunnel investigation of the air flow around single houses and in passages between two single buildings. Wind velocity around the house was measured using thermistors and results converted to isovel maps, that is maps showing curves joining points of equal velocity. Gives diagrams showing isovels.

Reports wind tunnel investigation of the wind pressure on houses. Tests were made on model of traditional form with sides in the ratio 1:3 and 1:6, roof pitch of 14 and heights of 2,3,4 and 8 storeys. Results were obtained in the form of pressure coefficients which are transformed into isobars using spline interpolation. Gives diagrams showing pressure coefficients and isobars for each test.

Outlines the problem of assessing the rate of heat loss from dwellings due to ventilation. Discusses the mechanisms and pathways of ventilation and ways of controlling air infiltration. Reviews methods of measuring ventilation using tracer gases. Discusses qualities of ideal tracer gas and three automated measuring systems. Reviews some experimental results obtained from the SEGAS test house. Describes house and measurement method. Finds sealing house reduced ventilation rates by between 30 and 45 per cent.

This is a short guide to the choice of a type of window, considering its position and exposure to wind. Defines exposure grades for windows. Gives recommendations for choice of windows considering air permeability, water tightness and wind resistance. The catagories of windows are as defined in standard N F P 20 302.

Describes method for measuring the direction and volume of air flows in a building with several rooms. The method uses carbon dioxide as a tracer gas produced from dry ice in each room. Over a period of 2-3 hours the concentration of gas in each room is measured every ten minutes. Gives equations for calculating air flows between rooms and some results of tests made on a flat.

Reports experimental investigation of moisture content of bathroom air during and after a shower. Describes test apparatus and procedure. Gives graphs of dry and wet bulb temperature, relative humidity and absolute humidity for various mechanical ventilation rates as functions of time. Gives results of measurements of tracer-gas decay rates for various mechanical ventilation rates. Presents theoretical model for calculations of moisture content in air in bathrooms and finds excellent agreement with experimental data.

This is a revision of the original standard, published 1959.

Gives standard test method for air leakage of joints between components used in the exterior walls of buildings. Outlines basic apparatus and test method. Resistance to air penetration shall be recorded expressed as cubic metres of air per hour.

Describes test apparatus and method of testing windows for air leakage. This standard has been adopted by the following countries :- Austria, Belgium, Denmark, France, Italy, Netherlands, Spain, Switzerland and United Kingdom. It is available in English, French or German.

Describes standard tests for air leakage, water-tightness and mechanical tests to be carried out on windows. Describes apparatus and test method. Defines normal resistance to air leakage as air penetration of 12 to 60 m3/h/m2 of the surface at a pressure of 10mm. of water. At air penetration of less than 12 m|3/h/m|2 the windows have improved resistance to air penetration.
