LoginDevelopes procedure for calculating air infiltration rates due to wind pressures on the exterior walls of buildings, assuming no chimney and mechanical ventilation effects. Assumes resistance to internal air flow is small.
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.
Access to the publications is free of charge.
Describes method of estimating roughness required to generate velocity profile of a given shape with a boundary layer of agiven depth.
Describes the importance and purpose of measurements of air infiltration. Discusses methods of measuring air-change-rate and the range of measurements.
States reasons for sealing joints:to increase sound insulation, protect from water penetration and to control air infiltration.
Reports measurements of the natural ventilation through a vertical sash-window in calm weather. Describes test window and room.
Compares annual fuel consumptions of seven large factories against calculated requirements to illustrate seasonal thermal efficiencies of 7.7 to 49.7%.
A review of literature reporting investigations of pollution in enclosed spaces.
Outlines causes of air infiltration. Discusses the air leakage paths of openings and measures that can be taken to reduce air leakage.
Reports wind tunnel tests of wind velocity, RMS velocity fluctuations and energy spectra for the streamwise velocity component in the lee of model fences of permeability 0% 20%, 34% and 50%.
Users' manual and documentation connected with computer program ENCORE. Program is based on weighting factor method.
A multitude of design strategies are available to achieve energy-efficient windows. Opportunities for improving window performance fall into six groups: site, exterior appendages, frame, glazing interior accessories, and building interior.
Suggests use of windbreaks to protect solar collectors and open air swimming pools and to protect buildings from the wind, thus contributing significantly to energy savings.
Working men's clubs are commercially thriving organisations catering for a wide range of social activities commonly held in a single room holding 300-400 people.
