Mitigations for Sustainability of the Megacities

The megacities are facing problems like increase in population, enhancement of environmental pollution, collapsing of traffic systems, and dysfunctional of waste management. The vertical extensions in the built-in-systems welcomed urban heat island (UHI) effect and enhance 5-10% more energy consumption. Thus, mitigation of UHI can be done by; i. reduction of albedo effect by introducing rooftop integrated photovoltaic (RiPV) systems, and ii. introduction of evapo-transpiration systems like water bodies, greeneries, green roof & green wall. Long term studies showed that introduction of RiPV systems in built-in-system not only reduce the albedo effect but also compensate the additional energy demand.
