LoginThe aim of this paper is to study the interactive phenomena in buoancy-induced natural ventilation in a full-scale enclosure , with upper and lower openings on one of the sidewalls.
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.
Gaussian-type dispersion models are currently used in most local authorities in UK, for the prediction of the air quality in urban areas.
The results of an interdisciplinary investigation of the thermal environment and the space heating in 20 low-energy terraced houses are presented in this paper.
A thermal comfort study is presented in this paper, a thermal manikin with a female body and 26 individually heated and controlled body segments is used in a field environment chamber.
Multizone models have already been developed to predict airflow and pollutant transport between rooms , and zonal models too to calculate airflow and temperature distribution within single rooms.For that study, a zonal model has been placed wit
The aim of that study is to evaluate the influence of temperature gradient and room air temperature (at 0.6 m height) on percieved air quality and Sick Building Syndrome in DV environment.
This paper deals with the cooling of air in raised-floor data centers mainly used for housing computer and telecommunication equipment.
For that study, a simple theoretical model has been developed for the prediction of the time taken to flush neutrally-buoyant pollutants from a naturally ventilated room. The flow is driven by localised heat inputs.
The new concept using continuous unipolar ion emission has proved its efficiency on facepiece respirators. So it has been applied to conventional HVAC filters, and the laboratory study demonstrates that it works well too.
This paper is an analysis of the measured outdoor air ventilation rates from the US EPABASE study that involved indoor environmental measurements, including ventilation, in 100 US office building using a standardized protocol.
A continuous monitoring of air quality parameters in 85 classrooms in Minnesota during one year has been done. Monthly reports of results helped the school personnel in planning and improving air quality when necessary.
Perceived health and comfort in relation to energy use and building characteristics | 2006 | English
96 apartment buildings and 64 office buildings were investigated for that survey in correlation with the european HOPE project. Occupants answered questionnaires to determine their satisfaction about comfort and health.
A methodology is proposed to perform a multicriteria analysis of health, comfort and energy efficiency in buildings. That methodology is applied to a sample of 64 office buildings and 96 apartment buildings.
For the numerical analysis of particle deposition velocity and deposited particle mass flux in the ventilation duct, CFD has been adopted.
This paper discusses a procedure of building calibration for indoor air quality management. The aim is to set the mimimum fresh air quantity in function of the indoor pollutant concentrations rather than metabolic carbon dioxide.
The steady-state distribution of contaminant concentrations in a workroom depends on several factors, among them the types of air inlets and exhausts and their relative position.
During winter 2000-2001, a field study was performed to investigate the thermal environment and the thermal comfort in residential buildings in Harbin, China. 120 participants answered subjective questionnaires and provided sets of physical data.
CFD has been applied to calculate the flow in a kitchen hood system at operating conditions.
For that study a CFD steady state computational model of a public transport interchange (PTI) in Hong Kong has been used for the investigation and prediction of the typical pollutant emission pattern for buses.
The differences and similarities between natural and mechanical wind in built environment are the subject of this paper. In that aim, a spectral analysis is applied to study the natural and mechanical wind characteristics in different conditions.
