LoginThe successful application of moisture simulation models to building envelopes requires accurate values of material transport properties. Unfortunately, although the presently-available database is reasonably voluminous, much of the informatio
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 traditional methods for the evaluation of the thermal performance of buildings are appropriate to winter conditions and are often used in standards that regulate energy consumption.
THERM 2.0 is a state-of-the-art software program, available without cost, that uses the finite-element method to model steady-state, two-dimensional heat- transfer problems.
In this report, recently developed computer program named TB3D/FDM(Thermal Bridge Computa- tion by 2- or 3-Dimensional Finite Difference Method) is introduced.
Based on the thermal and airflow network model with simple but perfect generic formulations and stable solving methods, a computer program NETS for the practical simulation of coupled building heat, gas and air transfer system has been deve
A coarse-grid zonal model of room air convection is formulated and written with the SPARK object- oriented simulation environment.
If an insulated and airtight house is cooled by passive ventilation using buoyant convection, the indoor air temperature can be kept lower than the outdoor air temperature, but there is a tendency for the indoor humidity to remain at a high level.
Located in an extreme arid natural environment, the city of Mexicali has confronted maximum temperatures of 54C during summertime.
In calculating the heat flows around the floor plenum of underfloor air distribution system, the convective heat transfer coefficient is an influential factor, but it is not clearly known which value should be taken.
In recent years there have been a number of research and development initiatives directed at integrated energy generation systems which can meet the energy requirements of a building substantially or even completely on-site.
This paper presents the Umidus program which has been developed to model coupled heat and moisture transfer within porous media, in order to analyze higrothemal performance of building elements when subjected to any kind of climate conditions. Bo
Up to now, within the framework of validation of the global building energy simulation software programme CLIM2000, we have not focused on analytical verification.
This paper referrer to the existence of the variety modes and the 'chaos' in building ventilation system, and provides some instances of such varieties and the chaos in forced ceiling chamber smoke exhaust system in building fire. The numer
There are two kind of supply fan rotation speed control methods, one is the static pressure control method, the other is the float pressure control method. Simulation shows that they have different working point along the whole year.
The Austrian Radon Project (ARP) is aimed to investigate and measure systematically the indoorradon concentration in about 0.5% of all Austrian homes.
The definition of radon prone area based on indoor radon survey and the statistical analysis of data (ICRP65) is a well known process.
Epidemiological evidence of lung cancer risk from radon is based mainly on studies of menemployed underground in mines where exposures are relatively high in comparison to indoorexposure.
The wind speed and wind direction affected concentration of indoor radon in seven houses, which arelocated in three region of southern Finland.
Legal regulations on the utilization of raws and materials assigned for construction are applied inPoland taking into account radiation protection.
Sub-slab depressurization (SSD) systems in the form of radon sumps are being considered as themost effective and the cheapest radon remedial measures for existing buildings.
