The Impact of Different Green Roofs Strategies on the Indoor Thermal Comfort with Special Reference to Cairo-Egypt
Abstract:
In present time, the environmental impact of green buildings on inner and outer climate has becomes more apparent. Green buildings are designed to reduce the overall impact of the built environment on human health and the natural environment. Recently, the popularity of green roof is growing in the context of urban landscaping because of its smaller footprint, aesthetic value, insulation benefits and heat island mitigation impact. Greenery roofs are considered to be a part of new technology that allows the use of alternative vegetation. This paper will explore the potentials of using green roofs as an integral part of the building process to save energy. This paper will introduce the energy crisis and will focus on the current crisis in Egypt and the global UHI effect. It will also identify the impact of vegetation as a sustainable approach for UHI mitigation and energy savings. After addressing green roof types, and their functional, and environmental aspects in general. The paper distills these different types to enhance thermal performance in terms of indoor thermal comfort and energy savings with the integration of PV cells within green roof design. This will be empirically examined by DesignBuilder and EnergyPlus Simulation, to explore the possibilities of improving indoor thermal comfort within the studied types. Then the paper will be concluded by a set of recommendations for buildings within Egypt’s climatic settings.
