LoginThe directionality of light is defined as the balance between the diffuse and directional components of light within an environment. It is an indicator about the spatial distribution of light flow onto an element or into a space.
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.
The AIVC website includes a protected content feature that provides access to AIRBASE. Access to the protected content is free of charge but requires you to register first.
District energy systems provide commercial and residential space heating, air conditioning, domestic hot water, steam, and industrial process energy, as well as sometimes co-generating electricity in systems.
According to the Czech legislative act the operative temperature is the evaluation criterion for thermal comfort in air-conditioned or heated spaces.
Over the past 15 years, much scientific work has been published on the potential human impacts on climates.
The daylight coefficient method has been introduced in computer simulation as an efficient approach to compute indoor daylight illuminances through building static fenestration systems.
While the scientific literature is full of studies looking at the impact of climate change driven by human activity, there is very little research on the impact of climate change or urban heat island on building operation and performance across th
This study developed a drift-flux model for particle movements in turbulent indoor airflows.
Bases on the concept of task/ambient ventilation, fresh air can be decoupled from re-circulated air so as to improving ventilation effectiveness in breathing zone.
This study assesses the extent of the cooling effects of waterways on the thermal environment of urban districts of Osaka by measurement and simulation. The thermal environments of districts with and without waterways were measured in summer.
This paper analyzed the influence of neutral plane on natural ventilation in workshop. For several typical heights of neutral plane of a molding workshop, its influence on ventilation was simulated by means of CFD.
To reduce the potential risk of airborne infectious diseases during an outbreak or to detect a chemical/biological release by a terrorist, it is essential to place appropriate chemical/biological sensors in commercial airliner cabins.
Reliable prediction of daylight availability in indoor environments via computational simulation requires reasonably detailed and accurate sky luminance models.
We present a prototypically implemented and empirically tested daylight-responsive lighting systems control in buildings that makes use of realtime sensing and lighting simulation.
The opening typology influences the ventilation of the rooms offering more or less resistance to the airflow.
Interior-surface condensation on the glazed curtain wall of high-rise residential buildings is an important environmental issue in Korea. There are three causes of the surface condensation.
Food odor dispersion from residential unit to core is one of problems in high-rise residential building.
Increasing attention is being paid to natural solutions to building design, e.g. mixed-mode (or hybrid) ventilation, or increased use of daylight.
The airtight window system adopted in highrise residential buildings or residential-commercial complexes recently in Korea gives rise to poor ventilation, deterioration of Indoor Air Quality (IAQ) and the overloading of cooling systems during the
Cities all over the world have been warming up in the summer over the years. Seoul, Korea, is also an example of how a city was transformed into an urban heat island.
By k− ε turbulence model, the indoor air fluid flow and heat transfer conjugated programs in the YZ25K air-conditioned passenger car are solved with SIMPLE algorithm.
