LoginThis paper describes a pilot study conducted in an occupied family house in Ohio to determine if a script-based protocol could be used to obtain data useful for the identification of the key factors affecting air-exchange rate (AER) and the rela
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.
This paper is a clear presentation of the different available systems to ensure a good thermal comfort : the author starts with passive systems that maintain comfort without an extra energy consumption, carries on with the low-energy consumpt
This paper gives the main results of a thesis whose main objective was the comparison of numerical and experimental values of indoor air quality. The tests were carried out at the CSTB .
First the author asserts that the filtration with the help of fiber means is the most widely used technique for the treatment of the particle-pollution.
The characteristics of the building that has been renoved according to the german standard "pasive house", are presented.
Concerning house ventilation, occupants are aware of the necessity of suppressing the vicious air but less of the obligation of entering outside air.
For that study a seated computational thermal manikin (CTM) is used to study the microenvironment around human body with or wihtout personalized ventilation system (PV).
Identifying health improvements in the upper and lower airways of office workers was the aim of that experimental field study.
For that study, 1014 pupils from 8 schools were questionned in the aim to study asthma and allergy in relation to diet and the school environment.
Porous building materials are sources of indoor air pollutants such as VOCs and strong sinks of these pollutants too.
A case study is presented in this paper regarding the fine particulate matter and its carbonaceous compositions in six residential homes in Hong Kong.
For that study a field survey on indoor environment in 10 office buildings with displacement ventilation was performed. The responses of 227 occupants were collected and analysed.
Experimental study of sensible heat recovery of heat pump during heating and ventilation | | English
In this paper, three methods of recovering sensible heat during heating and ventilation process of heat pump have been studied experimentally.
In order to investigate the difference between mixing (MV) and displacement ventilation (DV) under different boundary conditions, a numerical simulation with a validated CFD model of several types of buildings was used.
A numerical simulation with a validated CFD model of several types of buildings was used to investigate the difference between mixing (MV) and displacement ventilation (DV) under different boundary conditions.The second part of that study deals
To study the microenvironment around human body with personalized ventilation system, a seated computational thermal manikin is used.
Using the same system for natural ventilation and smoke control is the examined possibility of that study. In that aim a prototype building is proposed : it is an eight-storey building with a solar chimney located on top of the atrium.
The aim of that study is to model and evaluate the performance of several ventilation methods in pollutant removal from indoor environments. 3 different ventilation methods are examined : a displacement ventilation and two mixing systems.
For that study, measurements were carried out in an office-type experimental room to investigate the distribution of airflow velocity and air temperature.
For the characterization of PM (particulate matter) indoor/outdoor relationships for wind induced naturally ventilated residences in taiwan region, a simple size-dependent indoor air quality model was applied in association with measured outdoo
