VIG(Vacuum Insulation Glass) is made for maintaining vacuum in the gap between glass panes and its U-value is 3~5 times higher than double glazing. Insulation performance was examined by U-value and anti-fogging tests. Especially, U-value of hybrid vacuum glazing(Low-e glass + Kr gas + VIG) obtained in this study was 0.6 W/m<SUP>2</SUP>K. Heating and cooling energy performance was evaluated by simulation. Compared with double glazing, 40% and 36% of energy performance were reduced at Apartment building and at Office building, respectively.
