Building energy consumption accounts for 30% of the total social energy consumption, building energy saving affects the key factor of carbon peak. The outer structure of the building is composed of exterior walls which account for 0.3 of the total building area and and Window which account for 0.6 of the total building area in modern building. The windows have become the main channel for heat leakage. VIP (Vacuum insulation panel) has been successfully used in building external wall thermal insulation, a total of 100 million square meters in China, showing remarkable thermal insulation performance. Large area glass is an indispensable decoration and lighting in modern life. Its high thermal conductivity seriously restricts building energy conservation and thermal insulation. Single glass with insulation film, double glass, aerated glass and vacuum glass are being developed to meet the needs of carbon peak. especially VGP (Vacuum glass panel) with 20-30mW/mK thermal conductivity, combined with VIP with 2-5mW/mK thermal conductivity will play an unpredictable energy saving effect. In this paper, the combined using of VIP and VGP is used to build a building model, to simulate the environment in cold winter and hot summer, and to study its insulation and energy saving performance. On this basis, a standard room is built, data collection is carried out, and its actual efficiency is evaluated.
