Amplifying the practicality of contemporary building information modelling (BIM) implementations for New Zealand green building certification (Green Star). Issue 4 (17th July 2017) - GhaffarianHoseini, Ali
Abstract : Purpose: Green Star is becoming a broadly accepted mark of design quality and environmental sustainability. Compared to other green tools, Green Star is considered as one of main streams green assessment tools, which cover almost sustainable criteria. Simultaneously, building information modelling (BIM) has also been introduced into the industry. BIM is expected to aid designers to shift the construction industry towards more environmentally and economically sustainable construction practice. Whilst the aspirations of Green Star rating and BIM implementation are broadly aligned, in the context of New Zealand this has led to some disconnects in design strategy and process. The purpose of this paper is to improve the practicality of BIM implementations for delivering Green Star certification in New Zealand. Design/methodology/approach: The extensive literature review is conducted through a series of incremental steps. A conceptual framework focussing on the relationship between benefits and challenges of BIM and Green Star is then developed. Findings: BIM supports practitioners to achieve the majority of Green Star criteria (75 per cent). Energy efficiency criterion is the key factor affecting the assessment process of Green Star and National Australian Built Environment Rating System in New Zealand. Research questions about lessening the challenges which can be encountered during the BIM and Green Star implementation are developed. Research limitations/implications: This paper is limited to a conceptual research. Further empirical research should be conducted to validate and modify the conceptual framework and the propositions presented in this paper to provide an initial insight into BIM and Green Star connectivity within the context of New Zealand. Originality/value: This paper provided a clear picture for investors, developers, practitioners about benefits and challenges of BIM and Green Star implementation. The outcomes are anticipated to deliver visions for shifting the country further towards development of sustainable future cities.
