LoginReports tests of the air leakage of 24 houses made using a fan to depressurize each house. Gives a table of results including indoor humidity, air-particulate levels, energy consumption and comfort conditions for each house.
Bibliographic database Airbase
AIRBASE is the Bibliographic Database of the AIVC. It contains publications and abstracts of articles related to energy efficient ventilation. Where possible, sufficient detail is supplied in the bibliographic details for users to trace and order the material via their own libraries. Topics include: ventilation strategies, design and retrofit methods, calculation techniques, standards and regulations, measurement methods, indoor air quality and energy implications etc. Entries are based on articles and reports published in journals, internal publications and research reports, produced both by university departments and by building research institutions throughout the world. AIRBASE has grown and evolved over many years (1979 to present day, over 22000 references and 16000 documents available online). For most of the references, the full document is also available online.
The AIVC website includes a protected content feature that provides access to AIRBASE. Access to the protected content is free of charge but requires you to register first.
Briefly describes instrumentation and techniques for measuring concentrations of radon daughters in air. Reports measurements of radon daughter levels made in nine structures in Grand Junction, Colorado.
Describes apparatus used to measure full-scale wind loads on a glasshouse. Wind pressure was sensed by a Dines anemometer and the variation in wind velocity with height by a small pressure tube anemometer.
Discusses standards and guidelines used for calculating the heat demand over a heating season.
Measurements of dark smoke and SO2 concentration made inside and outside a school showed no significant difference in the case of smoke but SO2 concentrations indoors were only 71% of those outside.
During an extensive programme of sound insulation tests on a house near Manchester Airport the opportunity was taken to measure the field performance of partially open dual glazing.
Domestic demands account for about 40% of total energy supplies in Sweden. This article reviews research by the Building Technology Division of the Swedish Royal Institute of Technology over many years into the thermal behavior of houses.
Air infiltration rates are important in determining greenhouse heating requirements. Design recommendations usually suggest one to two complete air exchanges per hour under calm conditions.
Flat wood-frame house roofs with insulation applied between joists are susceptible to condensation problems in cold climates.
Describes a computer program written in 1900 fortran which is suitable for computing natural ventilation rates in multi-storey buildings. Lists the assumptions made, the data requirements and output available. Gives a print-out of the program.
States that to obtain accurate estimates of wind induced natural ventilation of buildings the pressure distribution over the building is required. Reviews the available information for isolated buildings and groups of buildings.
Describes computer program used to calculate the air flows and pressure differentials in a multi-storey building as a result of a combination of wind effect, stack effect and the operation of air handling systems.
Gives series of maps and a chart used to specify performance requirements for windows in the United Kingdom in a simple way. Gives maps for the design wind pressure and exposure grades.
Describes experimental method of determining air leakage characteristics of exterior walls of a building.
Heat load from passage of cold outside air to building interior is function of wind speed and outdoor air temperature. Analyses meteorological data to determine suitable design conditions for accurate assessment of infiltration heat losses.
Points out importance of ventilation heat losses in calculating total heat requirements of a building, and necessity of its analysis for multi-storey buildings.
