The current development in building energy efficiency towards nearly zero energy buildings (nZEB) represents a number of new challenges to design and construction. One of these major challenges is lowering the need for heating by means of highly insulated glazing units, unique glazing technologies, such as vacuum glazing (VG) or hybrid vacuum glazing (HVG). Hybrid vacuum glazing combines vacuum glazing with double glazing technology by adding one low-emissivity glass to the vacuum glazing using a thermally-improved spacer profile to eliminate the thermal bridge at the edge of the vacuum glazing. The gap between the vacuum glazing and the low-emission glass is filled with the inert gas Argon. The thermal performance of a hybrid vacuum glazing was tested using the guarded hot box method developed in accordance with the requirements of ISO 8990. Hybrid vacuum glazing has thermal transmittance about 0.43 W.m −-2 .K −1 .
