LoginThe present study deals with indoor air quality and is mainly based on an experimental work. The experimental set up is a full scale test cell with a ventilation system which comprises a fixed air supply and a mobile extract.
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 "step-down" tracer gas technique was used to evaluate experimentally in a mechanically ventilated test room the effect of varying thermal boundary conditions, inlet flow rates, and inlet - exhaust grids position on the Air Change Efficiency (A
Traditionally, prediction of ventilation systems performance has been based on deterministic approach, which implies that the spread of the input parameters values is zero.
Night-time cooling of buildings is a recognized way of reducing the use of air conditioning, and hence energy consumption.
We calculate the influence of thermal mass and night ventilation on the maximum indoor temperature in summer. The results for different locations in the hot humid climate of Israel are presented and analyzed.
As heat exchanges through building envelopes and undesirable internal gains have been reduced in the last years due to energy conservation efforts, the importance of the energy needed to heat, cool and move outdoor air for ventilation has increase
The effect on ventilation effectiveness parameters of the recirculation of air is investigated.
The evaluation of the ventilation effectiveness and thermal comfort for various industrial ventilation schemes has been carried out by 1:4 scale model experimentation.
54 fume hoods in three laboratory buildings in Norway were tested for containment using two tracer methods based on European and American standards, in addition to face velocity measurements.
Ventilation system has to be design in order to strike a balance between indoor air quality and energy requirements.So, the ventilation efficiency can be considered as a major issue to deal with this objective.
This research investigates the effect of integrating solar radiation, internal building mass, thermal insulation and natural ventilation on building thermal performance.
The Second Skin Facades can be an useful tool for increasing the efficient use of natural ventilation in order to decrease the energy consumption for ventilation and cooling purposes and to increase the indoor thermal comfort levels.
The focus of this paper is on controlling ventilation rate to provide acceptable temperature and relative humidity in the space being ventilated.
All buildings, depending on their design and particularly on how they are vented, are polluted to some extent with radon. Radon and its daughters may be trapped within buildings and accumulate there, thus threatening the health of their dwellers.
One of the significant factors affecting the quality of air in the built environment, particularly in the context of hot humid climates, is the design and implementation of the air-conditioning and mechanical ventilation system.
This paper describes an investigation into the ventilation performance and the indoor air quality of a portable classroom. Both field measurements and numerical simulations based on CFD (Computational Fluid Dynamics) technology were used.
This study involves comprehensive experimental measurements and CFD simulations in a mockup of a full-size classroom with realistic loads. Four different air distribution systems have been tested:
The objective of this project was to provide cool working conditions for a small number of Customs Department staff in a turn-of-the-century heritage building in Town ville at 19° S latitude.
