The normally used equation for calculation of infiltration flow rates into a house is a power law of which the exponent n is normally assumed to be 0.66 but sometimes values of 0.5 or even 1 can be seen in the literature.
Peterson F.
Natural and forced ventilation are directly and indirectly influenced by the pressure distribution around a building. Results of full-scale pressure measurements on a typical Swedish timber house are presented.
Handa K, Gusten J.
Since 1974 the french Authorities have insisted on energy being saved in all buildings. There was very strong pressure on manufacturers to obtain better sealed window frames .
Baets F, Jardinier P.
The investigation was divided into several parts: 1, measurements of a mechanical ventilation system, 2, calculation model for this system, 3, measurements of the air leakage of the facades of a flat and 4, calculation model for this flat.
Phaff J C, De Gids W.
For optimum building design it is of importance to investigate the comfort and the energy conservation obtained with different types of ventilation systems and levels of airtightness of buildings.
Lindquist T.
Measurements in a test room of 28.4 m3 located at the top of a 3-storey building have been made to determine ventilation rates of different natural ventilation systems.
Daler R, Haberda F, Hirsch E, et al.
The heat losses from small houses, due to transmission and ventilation, are estimated. The estimation i s based up on the house owness daily readings of electricity and water meters, and their notes on behaviour influencing the energy use.
Ahlander G.
The aim of the present study is to measure the possible health effects among tenants after certain characteristic energy conservation measures had been taken in their dwellings. Changes in comfort are also included.
Iversen M, Lundqvist G R.
The purpose of the project has been to determine the saving in energy obtained in the practical operation of an FTX-system -that is, a fan-controlled supply and exhaust ventilation system with heat recovery - compared to an F-system, which is sole
Svensson A.
The total energy consumption for five detached houses with air change rates of around 3 per hour right after construction, was measured and compared with estimated values, over a three-year period. Air change in the bedrooms was also measured.
Logdberg A.
Discusses the problems of designing ventilation for small houses. Small houses are considered to be far too elementary and there is no total view of the balance of energy and no regard for the interplay between different flows.
Gusten J, Harryson C.
This paper discusses the potential for achieving an "energy-efficient" ventilation system by improving design procedures for natural ventilation. It considers ventilation requirements and the meaning of the term energy-efficient ventilation.
Etheridge D W.
Describes experiments carried out in 4 low energy electrically heated houses incorporating extra thermal insulation and heat recovery mechanical ventilation systems.
Dickson D.J.
Uses the SEGAS "Autovent" constant concentration apparatus to measure the fresh air entering and the local ventilation rate in each cell of amulti-celled dwelling with both natural and mechanical extract ventilation.
Freeman J. Gale R. Sandberg M.
Explores the various roles that mathematical models can play in the design of energy efficient ventilation systems.
Liddament M.W.
Gives results from fiel trials of the performance of various mechanical ventilation systems. Carries out measurements in buildings built during the seventies, using the tracer gas decay technique with N2O. Tests 3 cases:< 1.
Boman C.A.
Uses mathematical models for formaldehyde concentrations in 3 normal rooms in a single family house to estimate ventilation rates needed to maintain the formaldehyde concentration below the Danish recommended indoor standard (0.15 mg/m*3).
Molhave L.
Describes a window opening survey concerned with identifying the objective correlates of window opening. Finds that the variation between households in terms of their total daily window opening is greater than that within households.
Conan G.
Outlines project where 25 representative dwellings from Birmingham Local Authority Housing stocks were monitored before and after energy retrofitting.
