A STUDY ON THE THERMAL PERFORMANCE OF THE VERTICAL GREENERY SYSTEM

Abstract

Due to the rising temperature globally, many research have been carried out throughout the years to source for various means to lower the rising temperature. Singapore too has been making continuous effort to lower the temperature which is constantly on the rise and also in making the country into a ‘garden city’. This has resulted in the use of abundance of vegetations throughout the island. However, the use of greenery had been kept at ground level for the past few decades until recently when the government started looking at other means of incorporating greenery into building façade. It first started out with research on the feasibility and potential benefits of rooftop garden and it is only then when the rooftops of many buildings started having greenery appearing. The utilization of plants for rooftop and sky rise gardens is one of the potential measures to mitigate the Urban Heat Island effect and has gained popularity around the world. Though rooftop gardens have proved to be viable in Singapore through careful planning, it is still insufficient to mitigate the effects of the rising temperature. Hence, many countries around the world including Singapore have started looking into the aspect of sustainability building, low/zero - energy building as well as other means of integrating greenery into buildings. Therefore, this report aims to study the thermal performance regarding the use of the vertical greenery system in Singapore. Experiments would be carried out to compare wall installed with this system and wall without this system. A further study on whether the amount of vegetation coverage would affect the thermal performance of the vertical greenery system would also be carried out.
