DESIGNING A GUIDELINE FOR GREEN ROOF SYSTEM IN MALAYSIA

Abstract

Green roof system is widely implemented because of its environmental and economic benefits and aesthetic value to a building. There are numerous successful green roof projects, both extensive and intensive in Malaysia. However, there is no specific technical guideline for the planning, design and construction of green roof system catered to the climate and background of Malaysia. The aim of the research is to propose and develop a technical guideline of extensive green roof system in Malaysia on the planning, design and construction aspects of vegetation, substrate, filter, drainage and root penetration barrier. Comparative literature review of guidelines from Hong Kong, Singapore and Sydney were leveraged upon to propose an appropriate guideline for Malaysia’s market. In-depth interviews were carried out with green roof experts to collect feedbacks on the proposed guideline in the validation stage. The output from this research will conceptualise a framework for a technical guideline for future implementation of green roof systems
