Abstract
Net-zero is a key focus of the UK government, as it seeks to lead the world in the reduction of carbon emissions. Targets have been set in law to bring its greenhouse gas emissions to net zero by 2050 and committing to a 68 percent reduction in carbon emissions by 2030. Currently, there is disparity between national government net zero strategy and industry and institution recommendations for whole life carbon assessment. This is evidenced by the differing language used and the scope of life cycle stages considered. Whilst government strategy has presented general environmental targets, there is no technical guidance for how this can be achieved. No research or work is available that integrates the software tools necessary to implement greenhouse gas emission design and assessment for UK buildings. The challenge identified in this Thesis, is the development of an approach for how net-zero buildings can be designed and assessed, aligning national net zero requirements with industry and institutional recommendations for whole life carbon assessment. To achieve this, an initial literature review is presented, describing the UK landscape in terms of net zero and whole life carbon assessment, underlying concepts such as specific regulatory texts, building energy simulation and life cycle assessment are introduced, as are enabling technologies and concepts including; building information modelling and automated compliance checking. The remainder of this Thesis focusses on the development of a design and regulatory framework, that integrates a building energy simulation and life cycle assessment co-simulation for the purposes of greenhouse gas emission assessment of UK buildings. Regulatory uplifts are proposed alongside, that align current requirements with the recommendations made regarding net zero and whole life carbon assessment. The framework is augmented and digitised following the latest UK automated compliance checking principles and a proof-of-concept implementation of the design and regulatory aspects of the developed framework and regulatory uplifts is explored against the current status quo. This Thesis concludes by documenting findings and reflections from the implementation of the proof-of-concept, which validates this research by comparing the experience of the implementation against simulations of traditional processes. This Thesis is the first to, present a methodology for dynamic (time-differentiated) co-simulation results and a methodology for GHG emission design and assessment of UK buildings, and whilst doing so, aligning government requirements for net zero and industry and institutional recommendations for whole life carbon assessment. This research is exploratory, simulation research, with a key outcome being the findings and reflections to guide future research in implementing the framework developed in this research in the real-world.
