Electricity energy trends in Hong Kong residential housing environment

Abstract

Energy efficiency in buildings is a key factor for sustainable development. This study examines the electricity consumption in apartments and communal areas for both public and private housing in Hong Kong. A tool based on Monte Carlo sampling has been developed to predict residential electricity consumption in terms of housing type, occupant load per apartment (tenant) and gross floor area per building (communal). The residential electricity demand forecasts for Hong Kong show that substantial energy savings (>670 GWh yr⁻¹) can be achieved over the next decade through adjusting the mix of housing types and reducing communal energy use. The outcome of this study is useful for urban policymaking and future residential development planning.
