The concept of "passive house" architecture was established on the basis of low-energy buildings in Germany in the 1980s. In 1988, Professor Bo Adamson (Lund University, Sweden) and Dr.Wolfgang Feist from Germany first proposed this concept. They believe that a "passive house" building should be a building that can maintain a comfortable indoor thermal environment without active heating and air conditioning systems. On behalf of this, ICESUN Tempered Vacuum Glass, with its best performance of insulating against radiation, convection and conduction, has launched a series of products like Environmental Vacuum Glass, Long Life Vacuum Glass, Safety Vacuum Glass and other Vacuum Glass for buildings.
