AbstractFacility quality is dependent on the performance of utility infrastructure and local weather conditions in addition to social context. Theoretically, improvements in facility quality such as energy performance should reduce marginal costs of consumption for occupiers so as to increase asset values. This research explores the relationship between expectations of building energy performance and the financial value of real estate. The United Kingdom was selected as a leading case, being a large economy that has enacted legislation committing the government to delivering ambitious emission reductions to mitigate climate change. Appropriate instruments are identified and applied to a diverse set of case study offices. A scalable method is employed for calculating value at risk from energy performance for buildings. This involves a novel approach to testing supporting system capacity through an exploratory analysis of 2050 end-states and demonstration on real world contemporary cases as a feasibility study. In doing so, the significance of systematic risks to building energy performance can be quantified. By comparing systematic excess returns for energy performance with rental value for a large sample a Capital Market Line for building energy management emerges, providing a means to shadow price the social impacts of climate change.
