SIMULATION RESEARCH ON NATURAL VENTILATION IN THE LOW-CARBON ARCHITECTURE DESIGN PHASE

Reasonable design of a building in the conceptual phase can fully exploit the potential of natural ventilation and make maximal use of local climatic resources.It is meaningful for design of low-carbon architecture.With one office building to be built as an example,the influence of the external openings and internal partitions on the indoor natural ventilation effect was numerically simulated.It was found that the mean wind velocity and impact factor of nature wind were larger by adopted the optimized scheme.The age of air indoor was mostly less than 5 min.And the effect of natural ventilation was well,which provided reference and technical basis for the natural ventilation design of the building.
