The Third International Workshop on
Natural Ventilation, Tokyo, Japan 16th March 2009
Introduction
The Third International Workshop on Natural Ventilation was held on
March 16, 2009 at the Architectural Institute of Japan hall jointly by
four institutions: the Tokyo University of Science, the Tokyo Polytechnic
University Global COE program, the National Institute for Land and
Infrastructure Management and the Building Research Institute of Japan.
The goal of this workshop was to allow researchers and practitioners in
the field of natural ventilation to meet and exchange information on the
latest research trends and results regarding natural ventilation and
cross-ventilation, and to spread interest in natural ventilation research
among young researchers and students.
The first workshop was held in 2003 with six leading researchers
invited. The results of the workshop were published in the March 2004
edition of the International Journal of Ventilation. The papers presented
in the second workshop in 2005 were also found in the June 2006 issue of
the International Journal of Ventilation.
For this third workshop, there were 12 presentations by eight invited
researchers and four researchers from the host organizations. The titles
of the presentations are shown below.
Presentations related to Policy and Strategy
- W. de Gids (TNO, The Netherlands) - "Advanced Ventilation
Systems for Classrooms"
- Yuguo Li (Univ. of Hong Kong, China, Hong Kong) - "Natural
Ventilation for Infection Control in Health Care
Facilities"
- Takao Sawachi (BRI of Japan) - "Estimation of Energy
Consumption for Cooling and Ventilation in Houses, -A Newly Introduced
Japanese Regulation to Evaluate Energy Consumption for Heating,
Cooling, Ventilation, Hot Water and Lighting"
- Martin Liddament (VEETECH Ltd., Univ. of Warwick Science Park, U.K)
- "The Applicability of Natural Ventilation"
Presentations related to Ventilation Mechanics and
Thermal Comfort
- Takashi Kurabuchi (Tokyo Univ. of Science, Japan) - "Domain
Decomposition Technique Applied to Evaluation of Cross-ventilation
Performance of Opening Positions of a Building"
- Per Heiselberg (Aalborg Univ., Denmark) - "Buoyancy Driven
Natural Ventilation through Horizontal Openings"
- Hisashi Kotani (Osaka Univ., Japan) - "Paper Review of
Cross-ventilation Research - Results from Activities of Working Group
for Natural Ventilation and Cross-ventilation in AIJ"
- Richard de Dear (Univ. of Sydney, Australia) - "The Theory of
Thermal Comfort in Naturally Ventilated Indoor Environments; "The
Pleasure Principle""
Presentations related to Heat Load and Application
- Masaaki Ohba (Tokyo Polytechnic Univ., Japan) - "Study on
Reduction of Cooling Loads in Detached House by Cross-Ventilation
using Local Dynamic Similarity Model"
- Shigeki Nishizawa (NILIM, Japan) - "Verification of Effect of
Cross Ventilation on Energy Conservation by the Experiment Simulating
Occupant Behaviour"
- Mat Santamouris (Univ. of Athens, Greece) - "Efficiency of
Night Ventilation Techniques"
- Yuichi Takemasa (Kajima Technical Research Institute, Japan) -
"Natural Ventilation with Dynamic Facades - Japanese
Example"
This workshop attracted nearly 100 participants with active discussions
and information exchange not only between researchers but also with
building designers and manufacturers of building components.
Unfortunately, we cannot record all the articles due to a problem of
copyright. However, there is sufficient to convey the atmosphere of the
workshop.
