Research on passive building energy-saving renovation based on energy consumption analysis
In order to reduce building energy consumption,it is necessary to carry out energy-saving renovation of buildings.In this paper,a high-rise office passive building is taken as the research object.Firstly,the energy consumption model is estab-lished,and the air conditioning power consumption and heating energy consumption are simulated and analyzed.On this basis,the envelope structure,outer window,heating and air conditioning of the building are reformed,and the energy consumption before and after the transformation is compared and analyzed.The results show that the total energy consumption of the reconstructed building is reduced by 72.66%,and the effect of energy saving and emission reduction is remarkable,which provides practical experience for energy-saving reconstruction in the construction field.
