Experimental analysis of vacuum pressure and gas flow rate in structured-core transparent vacuum insulation panels

open access: yesEnergy Reports, 2023
The notion that modern buildings should strive to be net-zero energy buildings (NZEBs) is widely accepted. One of the causes leading to high energy usage for space heating, resulting in avoidable carbon emissions, is heat loss via building windows.
