LoginResidential thermal distribution systems have significant energy and comfort implications due to losses from the distribution system in the form of leakage and conduction and poor distribution from room-to- room within the house.
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.
Duct leakage has been identified as a major source of energy loss in residential buildings. Most duct leakage occurs at the connections to registers, plenums or branches in the duct system.
Ducts that carry heated or cooled air are often internally lined with fiberglass for acoustic control and thermal insulation.
Since the oil crisis of the seventies, the interest given to buildings physics, indoor climate and energy use has strongly increased.
This report presents background to and advice on methodologies for sensory evaluation of indoor air quality (IAQ).
Eighteen laboratories from 10 European countries participated in a comparison organized in the frame of the project VOCEM, a 2.5 year research collaboration among 4 research institutes and 4 industrial companies.
A number of interzonal models have been developed to calculate air flows and pollutant transport mechanisms in both single and multizone buildings.
Radon as an indoor air pollutant has been extensively researched worldwide over the past thirtyyears. However, radon is only one of several other important pollutants present in the indooratmosphere.
If indoor radon levels are to be significantly reduced across Europe it is essential to ensure that allnew buildings built in areas affected by radon are protected against radon.In the United Kingdom the Building Research Establishment Ltd (BRE) h
This study describes an approach for measuring and modeling diffusive and advective transport of radon through building materials.
Indoor 222Rn concentrations are influenced by several factores which may change with time,thereby causing temporal fluctuations of radon concentrations in rooms.
Electret ion chamber (EIC) for monitoring radon consists of a stable electret (electrically chargedTeflon disc) mounted inside an electrically conducting chamber. PERM?
A national survey of indoor radon levels in Lithuania was performed between 1995 and 1998.
Radon progeny concentration is measured with a total alpha counting system in 185 dwellings in thetown of Thessaloniki.
A newly built radon calibration test bench called BACCARA is presented. A method of calibrationusing a secondary 222Rn standard is described and examples of calibration are given.
The indoor radon program in the US.
To evaluate the dose arising from exposure to Rn Decay Products (RDP) a term often used isunattached fraction defined as the ratio of the Equilibrium Equivalent Concentration (EEC) arising from unattached radon decay products (URDP) to the total d
Radon gas is now considered to be a health hazard when found in excessive amounts in the builtenvironment. The levels of radon vary greatly, with some geographical areas having very highlevels.
Raised radon gas levels are known to exist in mines and Show Caves, and in the United Kingdomthe Ionising Radiations Regulations 1985 require the employer to take action to reduce radonlevels by improving ventilation or restricting access, because
