Investigation on Energy Consumption and Energy Saving Renovation Analysis of Residential Buildings in the Main Urban Area of Taiyuan City
In view of the coexistence of different energy consumption levels of existing residential buildings in Taiyuan,the energy-saving transformation of old buildings in the main urban area is planned.Therefore,some buildings completed before October 1,2007 in the main urban area were investigated,and it was found that the heat transfer coefficient of the envelope structure was far from the limit value of JGJ 26-2018.Therefore,according to the climate conditions of Taiyuan city and the requirement of building energy saving of 75%,the proposal of energy saving renovation is put forward.According to the calculation of the completion of all the transformation in three years,the annual saving of coal will be about 133,100 tons.
