Development of a Simplified Lca Model for Residential Buildings in Indonesia

Abstract

The aim of this study is to develop a simplified Life Cycle Assessment (LCA) model for residential buildings in Indonesia, which can be used under relatively poor data availability conditions. As the initial step, a pilot survey comprising a small number of samples (n=11) was carried out in the city of Bandung in March 2011 to initiate the development of LCA model. It was found that most of the statistical data required for LCA were only available at the national level in Indonesia, while most of the residential buildings do not have design records. Moreover, the household energy consumption data were found to be not available. The results of initial statistical analyses indicated that there is a potential to develop simplified projection methods of embodied energy as well as operational energy and thus to obtain life cycle energy and CO2 emissions based on some explanatory variables such as total floor area, lot area or household income.

Evaluation of Energy Use in Public Housing in Lagos, Nigeria: Prospects for Renewable Energy Sources

“…In a specific study of a residential building typology in Brazil, life cycle operational energy intensity was found to be 17,500MJ/m 2 (Paulsen & Sposto, 2013). In contrast, the operational energy intensities in comparable Indonesian and Indian examples were found to be higher and in the range of 11600MJ/m 2 -32100MJ/m 2 and 37300MJ/m 2 -66850MJ/m 2 respectively (Surahman & Kubota, 2012aRamesh, Prakash & Shukla, 2013).…”

“…In the present study, operational energy sources were grid electricity, LPG, petrol and kerosene. In the Indonesian study (Surahman & Kubota, 2012a), operational energy sources were similar and included grid electricity, LPG and kerosene while the Indian study (Ramesh et al, 2013) was based on grid electricity supply only. Similarly, the Brazilian study (Paulsen & Sposto, 2013) was based on grid electricity and LPG using national consumption statistics.…”

Preliminary Study of Window-Opening Behaviour and Space Cooling Methods of Urban Households in East Malaysia

“…In most cases, occupants tend to use any solutions to restore their comfort level (Humphreys et al, 2013), affecting the total energy consumption. The highest contribution towards the household energy consumption is from using the air-conditioning system (AC) as the alternative cooling or a solution (Surahman & Kubota, 2012). The AC usage in Malaysian dwellings is significantly higher during nighttime to adapt to the uncomfortable condition that forced them to close the window, primarily due to the security and pollution factors (Arethusa et al, 2014).…”
