Challenges of Facilities Management in Managing Intensive Green Roofs in High-rise Residential

Implementing green roofs is becoming a growing trend in high-rise residential buildings, providing numerous benefits such as biodiversity, energy efficiency, and sustainable urban living. These green roofs are categorised into extensive and intensive types and require regular maintenance to ensure optimal performance and longevity. However, facilities management (FM) needs help with these maintenance practices, leading to leakages, mould growth, and building defects. The design of green roofs also poses challenges, as maintenance and sustainability are not considered during the initial design and construction stages. Additionally, a lack of knowledge among FM staff about green roofs can hinder the effective management and maintenance of these systems in high-rise residential buildings. Thus, this study was carried out to improve FM practices for intensive green roofs in high-rise residential buildings in the Klang Valley. The research objective was to investigate FM's challenges in managing intensive green roofs in these buildings. This research used qualitative methods, including semi-structured interviews with five FM professionals managing intensive green roofs in the Klang Valley area high-rise residential buildings. The findings reveal that FM's foremost challenges include financial constraints, maintenance issues, limited expertise, and a need for more knowledge among FM staff. To address these challenges, the study proposes recommendations such as income generation initiatives, preventive maintenance programs, landscape improvement, and technology implementation to streamline intensive green roof maintenance and monitoring processes. This approach addresses current challenges in FM practices and promotes a holistic approach to managing intensive green roofs in high-rise residential buildings.
