英文摘要: This study performs a comparative environmental and economic assessment of four different façade systems for low-cost residential buildings in Ghana. A framework is designed to incorporate BIM, Life Cycle Assessment (LCA) and Life Cycle Cost (LCC) to perform a holistic comparison of a Shotcrete Insulated Composite Façade (Shotcrete ICF), Galvanised Steel Insulated Composite façade (G. Steel ICF) and Stabilised Earth Block Façade (SEBF) against the conventional Concrete Block and Mortar Façade (CBMF). BIM models are developed to compute the environmental and economic impacts of each façade. The results are then subjected to a comparative analysis for different life cycle stages. The SEBF is proved to be the most sustainable facade as it reduces cumulative energy demand (CED) by 39.13 %, global warming potential (GWP) by 18.07 % and LCC by 47.87 % compared to CBMF. The Shotcrete IFC and G. Steel IFC are found to increase CED but decrease GWP. Other than the SEBF, the ranking of all façades under different indicators changes through the scenario analysis. The findings of this study provide useful guidelines for selecting facade systems and reducing the environmental and economic impacts of low-cost residential buildings in Ghana. © 2019 Elsevier Ltd Citation statistics:
