Gives a survey of the weather parameters used for the "Danish test reference year TRY" and the corresponding set of data from meteorological observations made during a 15 year period. Describes the measuring methods used for the most important weather parameters, and presents selected tables and diagrams with some of the most important weather data. Gives possible fields of application for the test reference year.

Describes Schlegel's test chamber for measuring air and water infiltration around doors and windows. This can record infiltration at any point around the frame to high light the exact source of a leak. This is used to test the company's own draughtproofing and weathersealing products and is available to door and window manufacturers for development work.

Describes the ways heat is lost through doors, including flow characteristics, the effect of wind and the effect of temperature difference. Suggests that automatic doors will pay for themselves in terms of energy saved by cutting heat loss through entrances.

Gives a series of short articles on air quality, air infiltration, and the ventilation needs of low energy buildings. These are -< 1. Sandberg M. Quantifying the pollution. Defines the quality of ventilation< 2. Warren P. Predicting infiltration rates. Explains BRE's method of predicting air infiltration in houses< 3. Getting close to zero. Describes the low energy EKONO office complex< 4. Sherman M. Grimsrud D. Which ventilation system? Shows that the choice of the economically optimum ventilation system depends on the tightness of the building.

Using miniature perfluorocarbon tracer (PFT) sources and miniature passive samplers, tests conducted in the lab and in a typical home successfully demonstrate the utility of the PFT kit as a means for implementing wide-scale infiltration meas

Studies a modern energy efficient office building in a series of experiments with mobile laboratories connected on-line with the building. Measures inorganic air contaminants (CO, CO2, NO2). Makes off-line measurements of volatile organic con

Examines airflow in the Glowworm cave of New Zealand using conventional methods together with experimental procedures using SF6 and CCL2F2 tracer gases. Results show that the rate and direction of airflow are a direct response to a thermally

Briefly reviews different types of air-to-air heat exchangers, and their relative efficiency. Discusses their effectiveness in removing indoor pollutants such as radon and formaldehyde from tight houses.

Studies a sample of 58 occupied homes in Rochester NY to assess 1. the effectiveness of construction techniques designed to reduce air leakage 2. the indoor air quality and air-exchange rates in selected airtight houses and 3. the impact on

Decribes the "collector chamber" method, where a room or whole building is pressurised and the air leaking through the target areas is collected with apressure compensated chamber to a measurement device.
