Abstract: Thermal and Visual comfort are two important aspects to be considered in the design of classrooms. These two factors have an important role in the performance of the students. With an idea of enhancing these two aspects, shading devices and light shelves were installed in the classrooms of the zero energy building for a physical parametric study in order to evaluate their performance in Singapore climate context. Zero Energy Building (ZEB) is the first of such building in Southeast Asia to be fully retrofitted with green building design features and technologies. However, in field measurements, due to the concurrent influence of various factors, it is difficult to segregate the exclusive effect of one single factor, or any changes occurring due to it. Therefore, dissertation aims to evaluate the exclusive effect and performance of the installed shading devices and light shelves in improving the thermal and visual condition of the classrooms with the use of the computational simulation. Certain existing arrangements were identified for solar control and daylight enhancement and were tested with computational simulation. Percentage of shaded area, reduction of mean radiant temperature, increase in the daylight levels and daylight distribution formed the basis of evaluation. In Singapore, the schools generally rely on natural ventilation and some earlier studies have shown the need to control the solar gain in the classrooms without compromising the daylight level inside the classrooms. Therefore, an evaluation of the performance and effectiveness of shading devices and light shelves used in this showcase building would craft precious knowledge and lessons to directly inform the design of Singapore school buildings in future.
