Abstract
The authors outline the
knowledge they have gained through their design experience on the efficacy
of natural ventilation in non-residential buildings in
Japan
. They also describe the various challenges which must be overcome to
deploy natural ventilation. It is hoped that the knowledge presented in
this paper will be of reference in the drafting of guidelines for the
research and design of future natural ventilation systems. Natural
ventilation yields great energy-saving effects, but it is also necessary
to make reference to and examine the numerous challenges which must be
overcome at all stages from design to operation, with reference to actual
conditions in Japan, and indicate the necessity of developing methods for
verifying the performance of natural ventilation.
Key words: Natural
ventilation, performance evaluation, measurement survey, ceiling fan,
cooling load reduction effect, Japanese climate, case studies, office
buildings.
