Vacuum glazing may be a further development to obtain lower U-values (Ug ^ 0.4 W/m2K) with double glazing, separated by a thin evacuated space of 0.5 mm to 1.0 mm. Vacuum glazing is already used for freezers and refrigerators that need (small) windows. This technology requires large numbers of produced units at moderate costs.

High-performance housing and its corresponding components, such as windows, described in this section, are a challenge for the building industry during the next few years. The possibility of achieving buildings that are almost independent from the delivery of fossil fuels is fascinating. The extra costs that have to be spent are an investment in a local market and a local industry such as handicraft and trade, which feeds many people. Furthermore, this is an investment in a future of low and decentralized power distribution, which will be less sensitive and less dependent on the delivery of fossil fuels.
