AGC Starts Construction of Net Zero-Energy Building (ZEB)

AGC Asahi Glass announces that it has started the construction of a net zero-energy building (ZEB*1) at its Kashima Plant.

With the use of AGC’s energy saving & energy creating products, the new facility is expected to achieve a total energy reduction of 114.7%*2. The construction is scheduled to be completed in December 2018.

With the 2030 greenhouse gas emissions target, which states a 26% reduction from the 2013 level, acceleration of ZEB construction is in an urgent need in Japan.

Under such circumstances, AGC has set the theme of “energy saving and energy creation with AGC products, and started the construction of a ZEB office that creates more energy than it consumes.

In this new building at the Kashima Plant, AGC’s heat-shielding/insulating products help reduce energy consumption while the PV modules on the roof as well as on the window panes create energy.

For the construction of the ZEB office, AGC has been certified for the subsidy of a ZEB-related project from the Shizuoka Environment Resources Association*3.
