Table 4 Energy-saving designs, characteristics, and application scopes of wall glass types
From: Green BIM-based study on the green performance of university buildings in northern China
Type | Practice | Characteristics | Application scope |
|---|---|---|---|
Low-E glass | Solar-radiant Low-E film-coated glass | Realizing the selective shielding of solar radiation energy, preventing glare from entering the room | It is used at high northern latitudes |
Hollow glass | Vacuum thermal-insulating glass Light-transmitting Low-E + air + transparent glass Light-transmitting Low-E + argon + transparent glass | Reduce the heat transfer coefficient of glass. Guarantee the indoor constant temperature and humidity performance | Hollow glass is mainly used in buildings that need heating, air conditioning, noise or condensation prevention, and no direct sunlight and special light |
Ultra-white solar glass | Applying a coating that can absorb solar energy to ordinary glass | It can achieve the absorption of solar energy, and being used for constructing solar eco-building and making solar radiator | Northern areas with strong solar radiation |
Double-layer respirable curtain wall glass | Double-structure glass curtain wall of external circulation type Double-structure glass curtain wall of internal circulation type | It is composed of inner and outer curtain walls to realize the effect of thermal insulation and energy conservation | Buildings taking curtain wall as the outer-building envelope for main facade in most regions |
