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.
This study was carried out systematically asfollows; at first, an investigation of grossbuilding-to-land ratio of real residential areawith GIs data was carried out.
Traditional and modem natural ventilationtechniques have been integrated in a hybridsystem for a retrofitting of a public building inthe city of Mazara del Vallo (Ttaly).
Recently, natural ventilation, which istraditional cooling method in Japan, hasbecome considered as the key method forcooling energy conservation.
In residential district, it is difficult to setappropriate wind pressure coefficient for crossventilation design, because there are various andcomplex parameters that influence the windpressure.
Tn this paper, using thc "SCTENCE vent"method for estimating the energy consumptionfor air conditioning in rcsidcntial buildings, wcevaluated the wind environment and theradiative conditions with respect to the targetbuildings in the case where th
Recently most houses in northern Japan have becomehighly insulatedand airtight, whichhave caused seriousproblems such as indoor air pollution.
This research concerns natural ventilation of the building with double-skin.
Natural ventilation systems in multi-familyresidential buildings should meet the needs ofreducing ventilation heat loss as well asproviding good indoor air quality.
A semi-empirical ventilation model was proposed for cross-ventilation. This model isbased on local dynamic similarity theory andwas coupled with COMIS and TRNSYS, whichare widely used for energy conservationsimulation.
In predicting the cross ventilation rate throughlarge openings, the use of general dischargedcoefficient , values for the conventionalorifice equation is not suitable.
Cross-ventilation is difficult to predict andcontrol because wind exhibits a large degree ofvariation in both speed and direction.Consequently, the design of a well functioningcross-ventilation system presently demandsthorough and often expensive
Considering density of housing in residentialarea of large cities in Japan, it is very difficultto secure sufficient daylight and lead daylightto whole space in the house. High side lightingis one of solutions for such situation.
The main objective of this research is thepresentation of a method for finding lightingand power outlet energy consumption volume,which is both easy to calculate, and possesses acertain degree of accuracy, fiom the Japanesebackground of few lighti
It is believed that one method of maltingeffective use of energy is the sharing ofhydrogen energy or heat and electricityproduced by cogeneration systems at multiplefacilities in the community.
Attention for and implementation of ventilation systems is a relatively new phenomena in Belgium (where the three Regions are in charge of regulations related to ventilation).
Displacement Ventilation approach is becomingan interesting alternative to mixing ventilationainong Canadian consulting engineers. Thispaper presents two recent DisplacementVentilation projects designed by two inajorCanadian engineering firms.
An investigation was performed in a middle-corridor-type elementary school in Tolcyo, Japan, equipped with an air-conditioning system for cooling.Temperatures and C02 concentrations weremeasured in classrooms, corridors and outdoors.Visual inspect
A survey of air conditioner temperaturesettings and clothing insulation was carried outfor university student rooms in June-Octoberduring daytime on weekdays in Osaka, Japan.The results are as follows.
This paper describes some qf the thinking behind the thermal comfort provisions of the new European Standard EN1 525 1 (CEN:2007) for free-running buildings. This standard deals with all aspects on the indoor environment.
