Whole-building calibrated energy performance simulation towards energy sufficiency and net zero carbon. Case study of a medium-sized hotel

Abstract

The Performance Gap between design/rating and operational energy consumption of buildings results from prescriptive approaches for estimation of energy consumption using regulated loads, simplified steady-state models and assumption of Notional/Reference Buildings. The increasingly stringent requirements on energy efficiency/sufficiency and emissions in schemes such as the Future Homes Standard and NABERS-UK for offices, aimed at achieving Net Zero UK building stock, necessitates performance-based approaches that include unregulated loads and post-occupancy energy epidemiology in benchmarking the energy performance of different building typologies. This paper contributes to benchmarking the energy performance of hotels using an existing medium-sized hotel in London UK, as Case Study (CS). A whole-building dynamic thermal model of the CS was done in IESVE software and calibrated with actual occupancy, energy consumption and envelope construction/thermal data. Simulation of the model with contemporary Meteonorm weather file gave total electricity and natural gas consumption of 144.58MWh and 158.59MWh respectively, while
