LoginIt has been shown by Bankvall that forced convection reduces the efficiency of thermal insulation considerably. The reductions can become drastic if the inner skin is not airtight. The leakage around a switch or junction box issufficient.
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.
Air velocities, air temperatures and dust and fluoride concentrations were measured in a burning shop of a pellet plant.
Caulks and sealants are used to fill and seal joints, in order to prevent draughts and the intrusion of rain and dust.
The proceedings of the Canada Mortgage and Housing Corporation industry/science seminar "Controlled Ventilation with Exhaust Air Heat Recovery for Canadian Housing" 26 October 1978
Briefly describes a heat exchanger designed for use in a tight, solar heated house. The exchanger consists of three 3in. galvanized steel ducts within an 8in. galvanized steel duct. The ducts can be assembled in any length - 33 ft.
Reports the development of a small air-to-air rotary heat exchanger for residential applications in progress at Ontario Hydro Ltd. A prototype has been constructed and tested.
Describes three research programmes measuring tightness of components, of specific areas of a building and of complete buildings. Defines the Belgian standards currently applicable.
The main objectives are 1) the collection, processing and evaluation of leakage data for opening doors and windows, obtained from certifications or tests, 2) evaluation of the influence of building technologies and component materials on leakage,
The distribution and level of pressures due to the wind on the external faces of buildings condition the working of ventilation systems and hence the thermal losses.
Infiltration heat loss has become more important in the energy loss of modern buildings. It depends on a variety of factors. Computer analysis points to the effect of storey number, ground plan features and exhaust ventilation systems.
The growing interest in the response of structures to turbulent wind forces and the realization of the important role played by root-coherence in the prediction of such response has led to the proposal of several expressions for the power
Unnecessary air infiltration ,draftiness, in buildings can be a major cause for excessive energy consumption.
In energy balance of buildings the ventilation losses are a big part, and this part is getting relatively bigger the better the enclosure of the building is insulated.
