Abstract

Through implementing sustainable construction, Malaysia has progressively contributed to tackling climate change. However, the focus on new green buildings tends to overlook the environmental impacts of existing buildings. Recognising green retrofitting as a means to achieve sustainability, this research aims to maximise economic benefits such as capital appreciation, higher rental revenue, and improved cost-saving elements from green retrofitting existing buildings, thereby reducing the need for new construction. The objectives are to identify the process of green retrofitting existing buildings, determine the factors influencing economic benefits, and formulate ways to maximise these benefits in the Malaysian context. A qualitative approach was employed for data collection. A literature review was conducted to better understand the topic, and the issues identified formed the basis of the interview questions. Semi-structured interviews with five (5) practitioners involved in green retrofitting projects in Malaysia were carried out to gather insights. Content analysis was used to interpret the data.The study proposes seven (7) stages for green retrofitting: project proposal, project initiation, building assessment, identifying and choosing retrofit options, tendering, site implementation, and validation and verification. Ten (10) factors influencing economic benefits were identified, including market value, building age and lifetime, envelope performance, occupant behaviour, technology, project management, external support, client resources, expectations, and public awareness. Additionally, four (4) key strategies are recommended to guide consultants in maximising economic benefits: adherence to green rating systems, post-retrofitting maintenance, government initiatives, and engagement with building owners. This research supports the effective implementation of green retrofitting in Malaysia, helping consultants deliver retrofit measures that optimise economic outcomes and inform client decision-making.
