LoginCities 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.
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.
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.
In a previous study, a whole room IAQ model consisting of multi-phase emission/sorption model for wall materials and room volume mass balance model catering for practical ventilation schemes was developed.
A methodology was developed to calculate health damages due to exposure to radon emitted to indoor air for use in dwelling life cycle assessment. Fate factors were calculated based on dose conversion factors and effective outgoing airflows.
The objective of this study is to investigate the possible transmission mechanism of inter-flat air cross-contamination under the condition of singlesided natural ventilation.
Bake-out with dilution ventilation is a potential technology that can shorten emission cycle of indoor VOCs and other hazardous gas, and then reduce indoor environment pollution brought forward by building materials.
Natural ventilation relies on less controllable natural forces so that it needs more artificial control, and thus its prediction, design and analysis become more important.
The proposition of an assessment method of wind condition in urban structures is presented in the paper. In the second part of the paper two virtual residential districts with different urban organisation have been investigated.
Traditional approaches to simulate airflow movements in buildings are computationally expensive and do not achieve real-time prediction of results.
This paper utilizes a probabilistic mold risk assessment method, introducing a novel mold risk indicator (MRI). The MRI captures the risk of mold occurrence at identified “trouble spots” under uncertainty.
The minimum illuminance requirement for New Zealand Building Code (NZBC) Clause G7 – Natural Light is currently not being met in some new apartments.
This paper highlights the difficulty of using energy simulations to answer general questions in typical building design scenarios.
Computational fluid dynamics (CFD) is a promising method to study the urban built environment. However, the pecularities of the urban wind environment are difficult to simulate with a CFD package.
Energy savings by integrating the daylighting availability in the electric lighting management contributes to the realization of ‘Green Building’. This paper provides a simulation and calculation of office building in North China with RADIANCE sof
The three-dimensional wind environment in Lanqiying community of Beijing city, which is complicated due to the dense distribution of the highrise buildings, is investigated by computational fluid dynamics method.
Here a generalized 3-D radiation simulation system is developed with Monte-Carlo and Gebhart method. There are two kinds of basic units in the system, which are surface unit for opaque objects and body unit for transparent objects respectively.
A new concept, the spatial flow influence factor (SFIF), put forward by us in our previous paper, provides a new insight into the airflow structure.
Scientific studies have linked particulate matter with a series of significant health problems. In ventilation systems, indoor particle concentration and dust load on air duct surfaces are two concerns for human health.
With the rapid development of computers and CFD, pedestrian level wind study using CFD has become important in engineering design in recent years.
Air age is an important parameter to assess indoor air quality in ventilated rooms.
