As traditional dwellings in southern Anhui, Huizhou style dwellings have been built for a long time, with serious aging structure, poor indoor thermal environment, and high building energy consumption, so there is an urgent need for energy-saving transformation of dwellings. This paper selects a traditional Huizhou style house in Shexian County, uses DeST to simulate the energy consumption, analyzes the energy-saving transformation of the envelope structure, quantitatively analyzes the energy-saving effect under different energy-saving schemes, and select the optimal energy-saving scheme based on the results of energy consumption simulation and the net present value method. After the renovation, the annual cumulative energy consumption of the building is reduced by 66.4%, the net present value during the life span is 13433.97 yuan. The energy-saving renovation is of practical significance to the improvement of energy saving.
