LoginThermal performance of climatic environments in Singapore for natural ventilation has been investigated.
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.
A draft perception study of Displacement Ventilation (DV) system in a Field Environmental Chamber (FEC) with tropically acclimatized subjects is presented in this paper.60 subjects, 30 males and 30 females, were exposed to 3 vertical air temperatu
The aim of this study is to investigate the distribution of different body parts’ surface temperatures in the space served by displacement ventilation (DV) system. The experiment was conducted in a Field Environmental Chamber in the tropics.
The aim of that study is to explore the influence of vertical air temperature gradient and room air temperature (at 0.6 m height) on overall and local thermal comfort of 30 tropically acclimatized subjects in a room served by Displacement Ventilat
Airflow fluctuation is an important factor that affects indoor thermal environment and human thermal response.
A field experiment was conducted in two classes of 10-year-old children. Average air temperatures were reduced from by 3 degrees and outdoor air supply rates were increased , each condition lasting a week.
Data linking poor IAQ in the classrooms to student performance is limited.
An individually controlled system (ICS) at room air temperatures of 20, 22 and 26°C has been tested by forty-eight subjects . Human response to a reference condition without the ICS at a room air temperature of 22°C was also collected.
An aircraft seat has been designed and constructed with displacement ventilation in the headrest. Tracer gas experiments revealed contaminant removal efficiencies up to 96% in the breathing zone.
Two prototypes of air terminal devices (ATD) for personalized ventilation have been developed for that study : the Circular Perforated Panel (CPP) and the Desktop-mounted Grille (DMG) .
The individualized control air conditioning mode can meet different needs of occupants to a greater extent than the traditional total-space air conditioning mode.In this paper, the authors consider that the total supply air system with variable a
This article deals with the perception of locally applied airflow from personalized ventilation air terminal devices by tropically acclimatized people.
An experimental and a numerical studies were performed to compare thermal comfort(TC) and indoor air quality(IAQ) in the lecture room for cooling loads when the operating conditions are changed.
The results of field studies in which the occupants of eight academic and office buildings, located in New Zealand, Australia, Germany, and Singapore are presented in this paper.
Ventilation airflow rate of the occupied houses in the northern region of Japan is the subject of that study.
Ventilation airflow rate of the occupied houses in the northern region of Japan is the subject of that study.
The paper deals with a nation wide field study in dwellings in order to assess household exposure to indoor air pollutants and related risk factors. It has been launched by the Observatory on Indoor Air Quality (OIAQ) .
For that study, an investigation of indoor air microbes of two Hong Kong Old Folks Home, one with naturally ventilation and another with mechanically ventilation device, was carried out.
The aim of that study was to clarify the differences in airflow characteristics outside and at three points in a cross-ventilated room under six opening conditions: window-open; insect-screen; lace-curtain; fabric-curtain; combined condition with
In this study, personal displacement ventilation (PDV), including two cases with all seats taken and two middle seats taken, is compared with overall displacement ventilation (ODV) of all seats taken under the condition that supply temperature is
