A Study to Compare the Cost of Operation and Maintenance in Green Building Index (GBI) and Non-Green Building Index (Non-GBI) Rated Building in Malaysia

Abstract

Abstract. Urges for sustainable development had pushed the government and professional bodies to respond and react by implementing regulations where possible to direct development in that manner. However, the outcome in most financial conferences and dialogues on sustainable buildings flagged on high construction and maintenance cost. Thus, this study is conducted to collect and analyze actual building operation and maintenance cost between GBI and Non-GBI rated buildings in Malaysia which are more than 2 years fully operated buildings. There are two categories of selected buildings which are residential and non-residential type of building. Each category of the building consists of similar building's characteristic such as geographic location, mode of operation, building heights, total numbers of floors and units. The scope of building's maintenance for this study is mainly on wear and tear of the wall painting, electrical light fittings, ceiling panels, roofing system and mechanical services like water pump system are recorded for their replacement frequency of service and the cost involved within a consistent period of 12 months operation at cost percentage saving of 78.9% and 40.4% for residential and non-residential buildings respectively compare against Non-GBI rated buildings. Electricity consumption for GBI rated buildings are lower than Non-GBI rated buildings which recorded at the cost variance of 23.8% and 6.3% and water consumption at 35.9% and 44.0% for the above mentioned two main categories of selected case study buildings. Results from this study conclude major savings on residential buildings category in term of maintenance cost and electricity consumption for GBI rated buildings. Whereby, non-residential category of buildings, GBI rated building had been proven to obtain significant savings in terms of maintenance cost and water consumption.

The Economic Challenges Affecting Sustainable Green Buildings (Sgbs) in Jordan Throughout the Project's Life Cycle Stages

“…The majority of financial conferences and dialogues on sustainable buildings expressed concern about high construction and maintenance costs [41]. The total of all labor, material, and other expenses incurred in conjunction with those actions and operations is referred to as maintenance costs [42].…”

Life Cycle Costing of Institutional Buildings in India: A Case Study of GRIHA-Certified CPWD Buildings

“…Vyas and Jha [21] carried out a study to determine the actual costs of operation and maintenance for green and non-green building types. Ping and Chen [22] compared the life cycle costs of green-certi ed industrial production facilities to those of conventional buildings to determine how sustainable characteristics affect life cycle costs. Biolek and Hanak [23] explained in their research that estimating life cycle costs of structures would allow investors to nd the most cost-effective functional material.…”
