LoginExamines ways in which air leakage affects building performance. Heating load and building relative humidity in winter are affected by over-all air infiltration and ventilation rates.
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.
Gives method for calculating air infiltration through window cracks. Calculates pressure drops across windows in buildings for four types of building and discusses resulting pressure differences. Gives values for crack width and length.
In this paper, the statistical concepts of the stationary time series are used to determine the response of a simple structure to a turbulent, gusty wind.
An analysis has been made of draft failure with residential heating units operating at low rates of combustion during mild, calm weather.
The quantity of air in several rooms lying in a stack connected by means of fresh air and exhaust air ducts is considered as a simple model of amultistorey building. Negative pressures set up within the rooms can be equalised by adjusting the
Describes a method for determining the rate of air change in a ventilated space using carbon monoxide as a tracer gas.
Describes measurements of air change rates using radioactive krypton as a tracer gas in a domestic house. Reports measurement of air change rates for a single room heated by either an open fire or a central heating radiator.
This paper is a review of past and current research on the subject of wind loads.
The authors show how the shape and surroundings of buildings and their situation in relation to prevailing winds affect the pressure distribution in a building.
Summarises measurements of natural outdoor environmental radiation made in the Eastern United States, in New England and in Western Europe.
The problem of describing quantitatively the effective ventilation in a room when the air within the room is imperfectly mixed is discussed. It is suggested that the protection afforded by the ventilation to any given position against air
Models are defined for various mixing conditions, in continuous flow systems.
Negative pressure inside a building may create adverse or dangerous conditions. Discusses when make-up air is necessary, how need is determined, and how much make-up, with examples.
Discusses causes of condensation between the panes of a double window. Treats movement of water vapour by diffusion and by air leakage separately.
Gives method for calculating infiltration of a building due to wind and stack effect.
BSTRACT Describes test made to determine air flow through entrances to a multi-storey building.
Explains forces causing stack effect in multi-storey buildings and suggests ways of reducing air leakage. Mentions that stack effect makes the operation of doors difficult and interferes with the operation of dampers.
