The traditional courtyard houses are investigated in the Xisi North historical and cultural district of Beijing's old city,and the residents are interviewed for their retrofitting demands,suitable retrofitting strategies are explored based on the improvement of the living environment,the changes in energy consumption before and after retrofitting are simulated with EnergyPlus,achieving low-carbon and energy-saving retrofit of the old city houses,and analyzing its significance in exploring the energy performance improvement of typical courtyard houses in China.The results of the study show that the retrofitted residential houses are good example of energy efficiency.The retrofitted residential houses consume 18960.21 kW·h of energy per year,with an average heating energy consumption of 19.64 kW·h/(m2·a)per square metre,a heat transfer coefficient of0.259 W/(m2·K)for the building envelope,0.181 W/(m2·K)for the roof,0.131 W/(m2·K)for the floor,and 1.1 W/(m2·K')for the external windows,which is in line with current regulations for residential energy eficiency in Beijing.If a set of traditional courtyard houses with better insulation performance can be passed on as an integral part of the urban regeneration process,it will contribute to the preservation of the traditional style of China's old city historical areas and the optimisation of low carbon and energy efficiency of traditional buildings.
