Abstract
A modelling framework that applies a design-forperformance approach to predict the actual operational energy consumption of buildings was presented in the latest published CIBSE TM54 (2022) in the UK. However, modelling uncertainty can lead to discrepancies between predicted and actual energy consumption. Identifying these uncertainties is crucial for enhancing the reliability of building performance simulation approaches. This study developed a modelling task for practitioners based on a simplified school building . The requirement was to simulate energy use in IES VE or DesignBuilder software using either the template-level HVAC modelling or detailed component-level HVAC modelling approaches proposed in CIBSE TM54. The predicted annual natural gas and electricity consumption from the 20 participants showed substantial variability, ranging from -74.8% to 157.7% and -74.3% to 114.9%, respectively. This paper contributes to further improvement and detailing of modelling framework in the future.
