Abstract
Thermal comfort is the state of mind in which one feels neither too hot nor too cold, thermal discomfort in the case of hot humid climates, becomes a great threat to our livelihood and thermal comfort in offices in general. The ability of designers to harness and use the
building envelope to make life much better and livable is of great importance. This research, therefore, seeks to use double-skin facade as a strategy for improving indoor thermal comfort by testing different air gaps between the double skins. Climate and Weather readings were
obtained and used to simulate and check the impact of double skin facades in improving thermal comfort in the office complex. The double skin facade study in this research involved computer simulation using Emissions Control Optimization TEChnology (ECOTEC). A specific software called Fluent is used. The result of the final base case shows that a double skin facade can increase the indoor thermal comfort in a building and the wider the air gap the higher the thermal comfort by increasing the indoor air velocity to about 0.8 m/s as well as reduction in indoor temperature. The other important factor is that it can continuously induce the flow of natural ventilation regardless of the available wind outside of the office complex building, this effect is significant toward improving the thermal comfort performance in the office complex through passive natural ventilation
