Industrialized Wall Components Impacts on Cooling Load Reduction and Carbon Production

Green building has now become a flagship of sustainable development in Malaysia that takes the responsibility for balancing long-term economic, environmental and social health. High total load green house gas emissions and inefficient energy consumption are the issues that the building sector in Malaysia is struggling with. To cope with these issues, Malaysian construction industry has been urged to use more innovative construction techniques like industrialized Building System and Building Information Modeling. This paper aims at evaluating the efficiency of various types of prefabricated wall components with regard to resource consumption and environmental impact and consequently, draws an analogy between them and the conventional types. The case study in this paper is a double storey bungalow located in Kuala Lumpur. It was modeled in Revit Architecture and exported to Autodesk Ecotect Analysis for energy simulation. Results show that the selected prefabricated walls, in terms of reducing the cooling loads, perform better than the conventional walls but this reduction is not significant. In general, this conclusion is drawn that IBS technology doesn’t play a conspicuous role in energy efficiency. However, its contribution to promote sustainability may fall in other categories
