Question: Environmental Impact Analysis on ResidentialBuilding in Malaysia Using Life Cycle Assessment
Answer: The building industry has a significant impact on the environment due to massive naturalresources and energy it uses throughout its life cycle. This study presents a life cycle assessment of asemi-detached residential building in Malaysia as a case study and assesses the environmental impactunder cradle-to-grave which consists of pre-use, construction, use, and end-of-life phases by usingCentre of Environmental Science of Leiden University (CML) 2001. Four impact categories wereevaluated, namely, acidification, eutrophication, global warming potential (GWP), and ozone layerdepletion (ODP). The building operation under use phase contributed the highest global warmingpotential and acidification with 2.41 × 103 kg CO2 eq and 1.10 × 101 kg SO2 eq, respectively. In thepre-use phase, concrete in the substructure has the most significant overall impact with cement as theprimary raw material. The results showed that the residential building in Malaysia has a fairly highimpact in GWP but lower in acidification and ODP compared to other studies.
