Abstract
The National Health Service (NHS) aims to reduce its direct carbon emissions by 80% between 2028 and 2032 and achieve net-zero emissions by 2040. To reach this target, evaluations of the current conditions of NHS properties and the effects of different refurbishment measures are needed. Due to the large number of NHS properties, creating individual models for each building is not practical. Instead, energy certification models (SBEM models) and the data they include offer valuable resources for evaluating the impact of various refurbishment measures on building performance. This study explores the potential of using data from SBEM models to develop dynamic simulation models and assess decarbonisation pathways through a case study building. For this purpose, an SBEM model of a healthcare centre located in London was adapted to create a performance model. After tuning the model based on measured data, it was used to simulate different refurbishment measures. The results indicate that to achieve the net-zero target, the building should be equipped with PV panels, in addition to refurbishments to the building envelope and technical systems. Moreover, to prevent overheating, especially under future climate change, additional measures should be considered, such as adding external shading or even active air conditioning. Overall, the results demonstrate the usefulness of SBEM models in assessing the decarbonisation measures. This approach can be scaled up and extended to all NHS properties that possess energy performance certificates to develop a stock model and gain a better understanding of the measures needed to achieve the net-zero target at scale.
