Research on Building Configuration Adapt to Natural Ventilation

Abstract

To achieve the objective building of low energy consumption and good air quality, the perception of “Natural first and mechanical second” should be highly preferred, and optimization should be started from the inception of the design work. Building configuration that can well adapt to natural ventilation should be paid much more attention to utilize (including control) the natural force as large as possible. In this paper, some building configurations adapt to natural ventilation have been suggested and discussed. Different ventilation effect depends on different thermal pressure has been studied and presented by simulation work. Multi-scheme comparison and optimization have been done by utilizing some evaluation indexes such as time of air exchange, average air age, energy available coefficient, etc. Further, research on regional adaptation has been also done by selecting four different meteorological regions in China from east to west. Based on our research work, some building configurations adapt to natural ventilation can be obtained and demonstrated.
