Abstract
Housing drives Australia's material footprint, energy demand and greenhouse gas emissions. Transitioning to a Circular Economy (CE) can decouple housing development from resource consumption and emissions. The Product-Service System (PSS), an integrated offering of products and services, offers promise for a CE by emphasising functionality over ownership. However, its implementation in housing remains complex, affected by a range of interrelated factors. This study adopts a qualitative systems science approach to explore these complexities in Australia. A Causal Loop Diagram (CLD) is developed from multiple data sources and refined through two Group Model Building (GMB) workshops with a diverse group of 13 key stakeholders. The CLD reveals six categories of interrelated factors affecting PSS deployment for CE housing: (1) cost of PSS deployment, (2) appetite for funding the PSS, (3) perceived risk, (4) client demand, (5) effective collaboration, and (6) profitability of the business-as-usual (BAU). Given this, an action framework is developed, including nine recommendations calling for action at both the housing supply chain and operating and institutional stakeholder levels to drive such a systemic change. This study contributes to the understanding of the dynamics of PSS implementation in housing, helping diagnose the challenges in scaling the PSS within the sector and offering recommendations for its successful integration.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
