Roof Pond with Intermittent Pumping as Passive Cooling alternative for Reinforced Cement Concrete Roof Top Slab

RCC roof slab retains more thermal energy when it is exposed to sun-light. This increases the room temperature. The increased temperature creates unacceptable thermal comfort to the occupants. In this paper, authors are investigating the effect of suggested passive cooling method to reduce the storage of thermal energy into the RCC roof slab. The roof exposed to sunlight is the most critical part of residential buildings. Indoor residential do not provide thermal comfort to occupants during peak summer, which creates an undesira-ble effect on occupant’s ability to function properly. Mechanical cooling devic-es like air conditioners are not environment-friendly and energy sustainable. The response time of the passive cooling system to irradiation remains slow. This is a desirable behaviour to control thermal variations which in turn moderates thermal loads concurrently. The author’s proposed the open pond with intermittent pumping which achieves the thermal comfort. The authors' seminal efforts are to design the passive cooling roof slab with minimal use of energy and further directions for the sustainability of energy systems, impact on day to day activity.
