Implementing zero carbon homes within commercial housing developments has proven difficult. This has resulted in a stagnated zero carbon housing sector and a lack of truly innovative designs within national house builder portfolios. Key industry stakeholders justify this by reference to a number of economic, regulatory, market, technological and structural based issues. This research develops an approach to zero carbon homes that brings design and commercial perspectives together to address these major issues. Out of this approach, an optimised design with a unique economic model has been developed. The economics of this design challenge the widely accepted notions of house price and affordability in traditional builds. The research findings are presented through a life cycle cost analysis. A significant finding from this research is that zero carbon homes could be better marketed on economic rather than environmental benefits so long as the user practice, technological and structural barriers are also addressed at the design stage. An exploration of stakeholder attitudes towards the mainstream take up is also carried out. It identifies and positions the key stakeholders involved in the implementation process using the Multi-Level Perspective (MLP) and Transitions Theory, generating a better understanding of what and who is required to transition the sector towards decarbonisation. In depth interviews and an observation study were conducted with these participants. This section of the research examines stakeholders opinions on whether the optimised zero carbon home is commercially viable. New insights are generated and existing insights from the literature are contextualised using the optimised design. This creates an analysis of its commercial potential. The research concludes by demonstrating the need to conduct further studies into wider systemic issues and to explore alternative routes to market.
