brief discussion on whether to replace glass or apply insulation film in energy-saving renovation. The door and window area of some public buildings accounts for more than % of the building area, and the energy consumption through doors and windows accounts for about % of the entire building. Energy loss through glass accounts for about % of the energy consumption of doors and windows, and glass energy consumption ranks first, accounting for about % of the window area.
The focus of building energy-saving renovation is on public buildings. The renovation of doors, windows and curtain walls is the key to building energy-saving, and the glass renovation is the top priority of energy-saving work.
There are only two options for energy-saving renovation of glass in existing buildings: one is to smash the original glass and replace it with energy-saving glass; the other is to affix the original glass with thermal insulation safety film for construction.
Building energy conservation includes energy conservation of new buildings (including reconstruction and expansion) and energy conservation renovation of existing buildings. Our country's existing construction area is 100 million square meters, and most of the buildings are not energy efficient.
The area of public buildings nationwide is approximately 100 million square meters, of which public buildings (shopping malls, office buildings, hotels) using central air conditioning account for 100 million square meters, and the energy consumption per unit area of public buildings accounting for % of the existing building area is approximately The energy consumption of ordinary residential buildings is about 10 times that of ordinary residential buildings, which can be called a large energy consumer.
Building thermal insulation film can independently provide sun protection and maintain the entire field of view of the window. It provides indoor comfort all year round, reduces energy loss by blocking heat gain, protects fabrics and furniture, and reduces harsh sunlight glare.
