The problem of the energy, comfort, and carbon performance gap (between design intentions and real-world conditions) of our buildings is well known. As our buildings become ever more complex in design and expectations, the gap continues to grow. Furthermore, the unintended consequences of design decisions become apparent only when buildings are occupied. This is further exacerbated by the changing climate, which places additional climate burdens on buildings, including overheating that leads to higher energy use, poorer thermal comfort, and greater carbon emissions. Real-world performance data and user-centred experiential evaluation are needed to improve the actual performance of our building stock. There is also a need to map, monitor, and model the changing climatic context in which our buildings are cited, especially in urban areas, to enhance their climate and carbon resilience.
