Achieving thermal comfort by applying passive cooling strategies to courtyard houses in Dubai (UAE)
The British University in Dubai (BUiD)
A passive design approach is centered upon integrating the microclimatic requests into the design to accomplish advanced comfort levels with lower energy depletion. The purpose of this research was to examine the cooling effect of designated passive parameters on the outdoor air temperature, wind speed , shading, indoor and outdoor daylight of an open courtyard. Numerous variables that demonstrated formerly to improve the outdoor environments were assessed conjointly to achieve the effect that passive design has over outdoor air temperature. The computer simulation was discovered to be the utmost appropriate tool for analysis affording to the resources accessible. Three variables were examined originally, orientation, geometry and vegetation among these the coolest parameter were combined into one scenario titled the enhanced scenario. Two scenarios entitled the existing scenario presents a specific site circumstances and the enhanced scenario conjoining the coolest parameters, were equated and assessed. The NW orientation, the highest geometry of a height to width (H:W) ratio of 1.35, groups of trees and continuous grass were discovered to be the coolest parameters included in the enhanced scenario. The enhanced scenario was then equated to the existing case scenario constructed with NNE orientation, 0.85 H:W ratio and no vegetation which had the higher temperature ranks. The outcomes discovered had a small increase in improvement of the outdoor air temperature owing to the passive principles pertained. The proportional outcomes performance cased a smaller progress among the enhanced scenario and the existing scenario presenting the site conditions of Dubai the villa owed to the assimilation of a these principles only. The outcomes of temperature and wind patterns verified and helped in accepting numerous outdoor performances which are helpful for directing an ecological design for courtyard spaces. One of the foremost conclusions was the reality of a limit to the amount of passive applications to accomplish a substantial enhancement still, an increase in it was achievable. Nevertheless, the performance of the outdoor parameters remains somewhat complicated and impulsive that involves additional exploration.
