LoginStates that in a tight house with a vapour barrier, an air management system is needed to provide fresh air and remove the build-up of moisture generated by the occupants.
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.
The Fanger Comfort Equation is coupled to a building simulation model. Discusses some factors related to thermal comfort. Incorporates variables influencing comfort as subroutines in the main thermal analysis program.
Evaluates the intensity and acceptance of body odour as perceived by 89 male and female judges entering 2 auditoria occupied by 50-200 men. Performs 200 experiments with varied ventilation rate, space volume per occupant and temperature.
Describes a detailed simulation program for estimating heat loads and room air temperatures of a residential building. Sets out the algorithms and the example simulation of a house by the program.
Describes the Computerized Instrumental Residential Audit (CIRA), a collection of programs for energy analysis and energy auditing of residential buildings. Air infiltration is modelled using the LBL infiltration model based on effective leakage.
Discusses MEPA (Microcomputer Energy Programs for Architects) which has been developed in Sweden to supply energy analysis information during the early stages of design of residential and small commercial buildings, and is used inSweden, Kuwait an
Grab sampling of a tracer gas/air mixture in conjunction with the tracer gas decay technique is a convenient method for conducting a survey of air infiltration rates in homes.
Reports on some current projects in the UK using a certain type of CO2-controlled ventilation system, the "Builiding Breathaliser".
Describes tests to investigate the sealing qualities of Kleeneze brushstrip (a fibrous draught-proofing strip) and the frictional forces exerted by it as the brushstrip compression is varied.
Reviews the mechanism of air infiltration as a background for introducing a procedure that yields more reliable estimates of average infiltration rates through a window unit than do methods currently employed.The procedure is applied to estimating
During winter experiments in central Pennsylvania a windbreak, 61 metres long and composed of a single row of white pine trees, significantly reduced air infiltration rates and space heating energy needs in a small mobile home by upto 54% and 18%
Describes a series of experiments performed on a residential attic under controlled laboratory experiments to obtain a better understanding of attics and attic insulation.
Studies the effects of permeability on the wind loading on a building. Compares experimental results from wind-tunnel tests with theoretical methods for estimating the mean and fluctuating internal pressures for various permeability.
Reports conclusions from projects investigating the tightness of buildings sponsored by the Ministry of Trade and Industry.
The report aims to provide the basis for the design and set up of experiments for the evaluation of the effects of energy conservation measures in residential buildings.
Parts 2 and 3 of a series of articles.
Describes the results of air tightness tests of various service penetrations through a polythene vapour barrier and associated insulation.
States that in localities which must be ventilated by law such as cinemas, restaurants and assembly rooms of various kinds the fresh air supply is often greatly in excess of what is strictly needed.
Discusses the problems associated with poor air quality in tight buildings. Considers how problem conditions can be identified and evaluated, and gives some possible solutions to improving air quality.
Despite having balanced mechanical ventilation, a large number of modern buildings in Sweden have unsatisfactory indoor climate.
