Abstract

Traditionally, residential buildings in the Caribbean relied on natural ventilation to regulate air quality and temperature. As urban areas developed, there was greater dependence on mechanical ventilation and air-conditioning. In a bid to reduce the carbon footprint, there is an impetus to promote methods of natural ventilation. This research completes Computational Fluid Dynamics (CFD) analyses, using a typical contemporary model home as a case study, to investigate the natural ventilation performance of two types of ventilation blocks, Arcadian and Innovent, available for use in residences in Trinidad and Tobago. Differences in terms of internal air velocity due to varying wind directions are compared for each type of ventilation block used which are primarily positioned in the upper portions of the walls. The Arcadian has been used since the 1960s, with the Innovent being a more recent addition to the Caribbean construction landscape. The air velocities varied across the elevation, and the wind direction was a critical factor in achieving maximum air speeds at indoor locations. The elevation-averaged internal air flow velocities were similar for both ventilation blocks investigated, and the changes in wind direction showed no significant difference in the overall ventilation performance characteristics when comparing the two blocks.
加勒比地区家庭的自然通风:一项数值调查
传统上,加勒比地区的住宅建筑依靠自然通风来调节空气质量和温度。随着城市地区的发展,人们对机械通风和空调的依赖程度越来越高。为了减少碳足迹,有一种推动自然通风的方法。本研究完成了计算流体动力学(CFD)分析,以典型的当代样板房为例,研究了两种类型的通风街区,Arcadian和Innovent,可用于特立尼达和多巴哥的住宅。由于风向不同,内部空气速度的差异被用于比较主要位于墙壁上部的每种类型的通风块。阿卡迪亚自20世纪60年代以来一直在使用,而Innovent则是最近加入加勒比海建筑景观的。风速在不同的海拔高度变化,而风向是在室内达到最大风速的关键因素。两个通风街区的海拔平均内部气流速度相似,风向变化对两个街区的整体通风性能特征没有显著差异。
