A Review of Green Roof Performance for Retrofitting Existing Buildings

Abstract

In addition to increasing the stored energy of pure liquid hydrogen and oxygen, green roofs are a practical way to increase the generated power capacity of both new and existing buildings. Because existing forms are more common, it is beneficial to perform extensive green roof animation when upgrading these structures. The essential harmony in the relationship is the primary constraint fashionable position indicated above. Consequently, insignificant systems continue to be implemented in order to prevent overtaxing the current building envelope. The movement of green roofs presents another possible obstacle. The most well-known feature of green roofs is their ability to provide unforeseen benefits and a sense of vitality and future growth. Various green roof designs are identified in this study, and their effectiveness is differentiated from previous research . Based on the reasons and results, retrofitting existing structure is only suitable for green buildings covering order with a load limit of 1.46 kN/m2. Regarding the relationship between a person's spirit and vitality, over the entire cold season of the year, the amount of chill strength consumed was decreased by 31–35 percent and the amount of calefaction energy consumed by 2–10 percent. The environmental advantages of grow roofs are computed and contrasted with those of non-grow roofs during the year's hot season. The findings show that 1.35 kg of CO2 and 0.03 kg of NO2 have been eliminated every year. Lastly, the financial analysis indicates that the reduced cost return ending of the something offered varies from 13 to 18 years old, depending on the substrates and plants used on the green building covering.
