Enhancement of natural ventilation in office buildings in Bangkok.

The office workers in Bangkok are accustomed to their environments of a hot-humid climate, resulting in a wider range of acceptable temperatures and higher comfort zone than the recommendation in moderate climate countries. This gives the possibility to use natural ventilation as a tool to provide occupants preference and comfort zone in office buildings, considering a short time experience. To achieve higher performance, the consideration has also to rely on the quality of airflow, which must derive from clean-air side and at high level of buildings to avoid effects of high air pollution of urban condition. The findings suggest the available materials that apprise the importance of the mechanism and advantages of natural ventilation namely cross ventilation, wind-scoop ventilation, background ventilation, and trickle ventilators. It is believed that these strategies and components can enhance the opportunities for natural ventilation to be applied in office buildings in the high-density land use in Bangkok.
