Energy-related environmental and economic performance analysis of two different types of electrically heated student residence halls.

Student residence halls occupy 26% of the total area of a typical university campus in the UK and are directly responsible for 24% of university’s annual CO2emissions. Based on five years measured data, this paper aims to investigate the energy-related environmental and economic performance of electrically heated residence halls in which space heating is provided by two different types of electric heaters, that is, panel heater (PHT) and storage heater (SHT). Secondly, using statistical and machine learning methods, the paper attempts to investigate the relationship between daily electricity consumption and five factors (ambient temperature, solar radiation, relative humidity, wind speed and type of day). Data analysis revealed that electricity consumption of both halls is mainly driven by ambient temperature only, whereas SHT residence has 39% higher annual electricity bill and emits 70% higher CO2emissions on a per square metre basis compared to the PHT residence hall.
