    How Can Decarbonisation Alternatives Be Prioritised to Achieve Carbon Neutrality in Building Projects?
    Too, J ; Ejohwomu, OA ; Hui, FKP ; Herath, N ; Duffield, C ; Soules, JG (ASCE American Society of Civil Engineers, 2023-01-01)
    The built environment generates approximately 40% of the annual global carbon emissions. To achieve the Paris Agreement target towards net-zero emissions, timely and sufficient plans for emissions reduction in the sector need to be made. One of the optimal strategies to realize sustainable structures is to select decarbonisation alternatives that will present a holistic view of environmental impacts. This research effort examined how decarbonisation alternatives are prioritised to achieve carbon neutrality in building projects. Based on extensive semi-structured interviews with experts, this research identified energy, emissions, economy, and exergy (4Es) as the four critical variables considered when making decarbonisation decisions. These 4Es were then assigned to different evaluation criteria, resulting in a total of 27 evaluation criteria. These findings will assist built environment professionals to prioritise decarbonisation alternatives across the entire project lifecycle. It will also provide policymakers with new insights for assessing potential impacts based on these four variables.

    Integrating sustainability into higher education curricula
    Rajabifard, A ; Elisa, L ; Herath, N ; Hui, K ; Currie, G ; Kahalimoghadam, M (Engineers Australia, 2021)
    Education has been widely recognised as a key instrument to achieve sustainability. Integrating sustainability knowledge, skills and values are considered paramount to enable individuals to contribute to sustainable development. The paper presents a pilot study conducted at the University of Melbourne to investigate the links between the subjects offered by the University and sustainability. The pilot study is a part of the Sustainability in the Curriculum program, which addresses the Sustainability Plan Teaching and Learning Target 1, aimed to incorporate sustainability knowledge and values in the University's curricula. The 17 Sustainability Development Goals have been used as a framework to measure how well the curricula are linked to sustainability. A study first undertaken to establish the link between subjects and the Sustainability Development Goals is presented. The study involved data collection through published literature on Sustainable Development Goals and the University's subject handbook, followed by a survey involving the subject coordinators. The findings of the study show that the strength of linkages between subjects with sustainability varies, highlighting the challenge in some technical subjects in linking their contents with sustainability. Approaches adopted in the Faculty of Engineering and Information Technology in embedding sustainability in the curriculum are presented with some examples and discussions for the next steps.
