Abstract: Passive cooling systems such as shading are important towards combating climate change as it enhances thermal comfort and mitigates Urban Heat Island (UHI). It is essential to look into potential energy-saving systems which can further reduce the heat gain of a building due to Singapore’s dense population. However, there are various shading systems available in the market, each with different thermal and physical properties which may have an advantage over the other. This dissertation aims to present a holistic overview of the thermal performance of different shading systems and investigate the potential ways that the shading systems can further reduce the heat gain of an indoor environment. A literature review was conducted to shortlist the shading systems with the highest cooling potential; Distilling it to horizontal shading, horizontal angled shading and roller shades. Next, experimental studies were carried out at the Tropical Technologies Laboratory (T2 Lab) to investigate the impacts of these selected shading systems on heat gain in the indoor environment. The experiments yielded the following results; In Singapore’s tropical climate, the Horizontal Angled shading provided the best thermal performance. The Horizontal Angled shading had a lower U-value, and the largest reduction of the external wall temperatures and hence heat flux, resulting in the most ideal indoor thermal comfort. Further studies should be undertaken to investigate novel shading devices with varying thermal properties such as dynamic shading. Additional efforts should also consider implementing the best shading devices concurrently and against varying orientations.
