An empirical examination of Green Star certification uptake and its relationship with BIM adoption in New Zealand

Purpose Green building information modelling (BIM) has been highlighted as an essential topic owing to its potential benefits. However, both Green Star and BIM are still in their earlier stages in New Zealand. This paper aims to examine and evaluate the benefits, barriers/challenges and solutions for the integration of Green Star and BIM in New Zealand. Design/methodology/approach In this paper, a total of 77 responses collected from construction professionals in New Zealand using questionnaires were analysed through descriptive and statistical tests. Findings Building performance modelling used for Green Star assessment can be implemented using BIM; this was highlighted as the most significant benefit of the integration. Whereas, the most significant barrier preventing the integration of Green Star and BIM was the fact they are two completely separate processes. Regarding the solutions for the integration, showcasing BIM-Green Star benchmark projects was considered as the most effective solution amongst a range of eight provided. Originality/value The research provided insights into Green Star–BIM integration in New Zealand. By evaluating the significance of the benefits, barriers/challenges and solutions for the integration, this research could be used as a guideline for Green Star and BIM development by New Zealand Green Building Council (NZGBC), the Government and construction practitioners in New Zealand. Specifically, the results here could be valuable inputs for Green Star manuals and the New Zealand BIM handbook.
