Energy saving effect
Hybrid glass 20% or more cost reduction in air-conditioning as compared conventional IG unit with Low-E and Ar gas injection.

Annual air conditioning cost (Yen/Y) Performance in preventing the condensation
In case of glass combination like LowE(2)-Air12-Vacuum ES described in Table3, relative humidity in room seen the condensation on roomside glass surface is extremely improved for the higher as shown in Fig 8.
For instance, when the roomside is 20 oC in temperature and 80% in relative humidity, no condensation appears on roomside glass surface up to -23 oC of outdoor temperature.
In this way, Hybrid glass is beneficial for the application suffering from the condensation on glass such as roof window, showcase, refrigerator door and so on.
