Abstract

Several studies have proved that incorporating the use of green roofs can optimize overall building performance and increase the building’s energy efficiency. This review targets different scenarios of green roof as a solution in addition to studying its various types and their effect in order to better optimize the results. With a structured analysis and cohesive interpretations through simulations and analytical cooling design extracted from EnergyPlus modeler, findings were assessed, and a conclusion was set to choose the best scenario. In addition to, other parameters that were taken into consideration which specifies the level of the green roof covered area along the whole space. This paper is a mere motive to demonstrate that simple changes that are innovative and sustainable can affect the long-term energy efficiency of the building. By Such, the simulated five scenarios demonstrated and tested showed that covering basic roof with 70% of total roof area with green intensive roof, was proven to increase the zone sensible cooling from an average of -49.478, scenario one, to -24.47 kW, scenario five, in the main waiting area.
