Life Cycle Energy and CO2 Emissions of Residential Buildings in Bandung,Indonesia
This study aims to develop a simplified life cycle assessment model for residential buildings in Indonesia, which can be used under relatively poor data availability conditions.In order to obtain material inventory data and household energy consumption profiles for constructing the above model, a survey was conducted in Bandung in 2011.This paper analyzes life cycle energy and CO2 emissions employing an input-output analysis-based method within unplanned houses (n=250), which are classified into three categories, namely simple, medium and luxurious houses.The results showed that the average embodied energy of simple, medium and luxurious houses was 36.3, 130.0 and 367.7 GJ respectively.The cement consumed the largest energy and emitted the most CO2 emissions among all materials.The annual average operational energy of simple, medium and luxurious houses varied widely at 11.6, 17.4 and 32.1 GJ/year respectively.The energy consumption for cooking accounted for the largest percentage of operational energy.The profiles of life cycle CO2emissions were similar with those of life cycle energy.The factors affecting embodied, operational and life cycle energy were also studied.
