Recently, "Scorching weather in Sichuan" has often been the hottest topic online. Severe power shortages, extensive power restrictions, and power blackouts have become a public concern. In addition to Sichuan, Hubei, Zhejiang, Anhui, and other provinces have also issued notices of power restrictions, giving priority to the needs of residential consumption and public services. A race between the high electricity demand in heat waves and power supply has quietly unfolded.

The critical situation between power demand and supply is not only a result of supply shortage but also related to the rising power load. Taking Sichuan’s high temperature as an example, the power load caused by air conditioner units is approaching 18 million kWh, more than 1/3 of overall electricity consumption in the Province. As a major energy-consuming sector, how can we effectively control the energy consumption of windows, doors and curtain walls while maintaining the comfort of living? The emergence and applications of LandVac have given the solution: As a representative product of high-performance vacuum insulated glass, the thermal insulation performance of LandVac is four times better than ordinary insulated glass: In cold winter, LandVac vacuum insulated glass works like a thick layer of "transparent cotton quilt" to keep away from the cold while in hot summer, it works as a heat insulation layer to retain the cool indoor air and keep radiation heat out. According to the relevant testing, using LandVac vacuum glass can significantly reduce indoor energy consumption. Taking a 100-square-meter dwelling house as an example, it can reduce the power consumption of air conditioning by 20% and heating by 30% throughout the year, saving energy costs of more than 3,000 yuan. The economic effect is quite remarkable.
