The Application Value of Low-E Glass in Green Building Certification

2025-07-17 14:24:30

Low-E glass (low emissivity coated glass) has significant application value in green building certification, mainly reflected in the following three aspects:

Energy conservation and consumption reduction

Low-E glass can reflect infrared radiation through metal oxide coating, blocking more than 80% of solar thermal radiation in summer and reducing indoor heat loss in winter, reducing air conditioning and heating energy consumption by 30% -50%, directly contributing to LEED, BREEAM and other certified "energy efficiency" ratings.

Environmental performance

Its production adopts offline magnetron sputtering or online CVD process, without harmful substances such as lead and mercury, and has a lifespan of more than 25 years, which meets the sustainability requirements of green building materials. When paired with hollow/vacuum structures, the U value can be as low as 0.8W/(㎡· K), far exceeding that of ordinary double-layer glass.

Comprehensive benefits

The visible light transmittance can be adjusted (40% -75%) to balance natural lighting and shading needs. Case studies such as Beijing Daxing Airport have shown that its application can increase the overall energy efficiency of buildings by 15% -20%, making it a key technology option for obtaining green building star certification.
