Abstract

Taking existing brick-concrete structure residential buildings as the research object, considering from four aspects of “policy, economy, residents’ willingness, existing style” and taking “suitability target” as the principle, this paper conducts on-the-spot investigation on the structure of existing brick-concrete structure residential buildings, and summarizes the material characteristics and existing problems of the exterior envelope structure of existing brick-concrete structure residence. Based on this, a set of energy-saving reconstruction model is put forward to strengthen the fine thermal insulation design of weak links (such as thermal bridge, through-wall holes, external window, etc.) and keep the original style of the residence. An existing brick-concrete structure residential building is selected to simulate the energy consumption of the designed energy-saving transformation technology mode, and the current energy-saving transformation mode and the suitability target energy-saving transformation mode are quantitatively compared and analyzed in terms of energy-saving and economy, and the residents’ will and existing features are qualitatively compared and analyzed. Finally, it is concluded that the energy-saving transformation mode guided by the principle of suitability target is more implementable.
