LoginTo evaluate effect of indoor environment quality on productivity, the changes in cerebral bloodoxygenation by near infrared spectroscopy was examined.
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 assessment of the overall thermal insulation of the air shear layer surrounding a nude humanoid shape, as affected by different step rates, is the main objective of the present study. Step rateswere controlled at 0, 20, 30 and 45 steps/min.
The present study is directed toward an accurate analysis on the transport of sensible heat overa realistically shaped human body model by way of a coupled convection-radiation simulation technique.
In the case of moderate climates, convective and radiative heat exchanges are the main avenues for heat losses on a human body.
In this article a prototype application of an interactive CFD-based computational steering system is presented, connecting a high performance computer (HPC) with a Virtual Reality (VR) environment.
For the application of personalized (PV) in practice, it is important to recognize its performance under realistic conditions as they apply in rooms.
Subjective experiments with a non-isothermal task conditioning system were conducted toinvestigate impacts of the system on thermal comfort and productivity in a climate chamber of Kanto-Gakuin University, Japan.
Air exhaled by occupants may carry infectious agents and be one way of transmitting respiratory diseases in rooms.
A distribution of contaminants from floor covering, exhaled air and human bioeffluents was examined in a mock-up of a typical two-person office by means of tracer-gases.
In this paper, characteristics of the indoor environment utilizing hybrid ventilation system andtask-ambient air-conditioning system are investigated every hour in a year in various types of office spaces by means of dynamic cooling and heating lo
In this study the concept of ‘adaptive behaviour’ is extended to look at the effects of personal adjustments and regulator control changes provided in offices.
The performance of two personalized ventilation systems combined with mixing or displacement ventilation was studied under different conditions in regard to thermal comfort of seated occupants.
A personalized ventilation system combined with a seat is introduced in this paper. This kind ofventilation seat is able to provide occupants with improved air quality, individual control and energysavings.
Task conditioning system is expected to reduce energy consumption in buildings and also toimprove thermal comfort of occupants. In this paper, an isothermal task unit was developed and its impact on subjective feeling was invesigated.
Thirty human subjects participated in experiments with five different air terminal devices forpersonalized ventilation operating at two levels of room air temperature within the range prescribed instandards for thermal comfort, namely 23C and 26C.
A detailed study using Computational Fluid Dynamics (CFD) was conducted on the influenceof the difference in the effective diameters of air supply outlets (wind velocity, assuming the airflow rate to be constant) when using personal air conditioni
This paper presents the main results of a research on an individually controlled office environment.
In this paper micro-environment around human body with a personalized ventilation system ina displacement ventilated room was simulated by the standard k-e model.
This paper reports the function and the performance of chair mounted isothermal airflowgenerator system.
Achievement of thermal comfort can be improved if individual control of the environment is allowed,namely through a local heating system (LHS), consisting of individually controlled radiant heating panels, adapted to a common office desk to a seat
