Meeting carbon emission reduction targets successfully will require a major shift in the performance of buildings.
The complexity of the building stock, the importance of buildings in people's lives, and the wide spectrum of agents responsible all make buildings an important area of 'policy resistance'. Policies may fail to achieve their intended objective, or even worsen desired outcomes, because of limitations in our understanding of the building stock as a dynamically complex system. This limitation can lead to 'unintended consequences' across a range of outcomes.
The concept of the 'performance gap' with regards to the energy performance of buildings is now well established and useful work to begin to understand this challenging issue has been undertaken. However, potential unintended consequences related to the inter-linked issues of energy/Indoor Environmental Quality (IEQ) present an even greater and more complex challenge - a challenge that is gaining increasing importance in both the UK and China. This project represents an exciting opportunity to address the issue of 'total performance' in order to reduce the energy demand and carbon emissions of buildings whilst safeguarding productivity and health. Individual work-packages (WP’s) investigate component issues and are subsequently drawn together in a dynamic integrative process.
WP1 examines the contrasting context within which buildings have been designed and constructed and within which they are used and operated internationally, addressing the policies and regulatory regimes that relate to energy/IEQ but also the assessment techniques used and the ways that buildings are utilised.
WP2 builds on this analysis by undertaking a monitoring campaign in both countries to allow comparisons between the performance of the same types of building in the two different contexts. Evaluation of how energy/IEQ performance varies between building type and country. This package will enable the assembly of a unique database relating to the interlinked performance gaps, developing semi-automated building assessment methods, technologies and tools to enable rapid characterisation of probable pathologies to determine the most cost-effective route to remedy the underlying root causes of energy/IEQ underperformance.
However, energy/IEQ issues do not form a closed system. In the development of relevant policies and regulations, it is vital to consider the wider system, which is addressed in WP3. The team at UCL has undertaken pilot work within the housing sector as part of the EPSRC funded Platform Grant ('The unintended consequences of decarbonising the built environment'), successfully employing a participatory system dynamics (PSD) approach with a team of over 50 stakeholders and we extend that work here to other building typologies. Such an approach can help support decision-making in complex systems, addressing challenges central to the TOP work. WP4 will govern dissemination of the research.
