Gakken Group uses “energy use intensity" as an indicator of efficient energy use. Since the 8th period, we have converted the amount of electric and gas energy for the entire Group into the crude oil equivalent and divided it by sales as the basic unit, making it an objective measure that can respond to fluctuations due to business expansion and other factors. As shown in the table above, the basic unit cost of energy use has been decreasing due to improvements in lighting equipment and business efficiency.
In September 2019, most of the lighting in Gakken Tokyo Headquarters was replaced with LED lighting. By using energysaving LED lighting, we will continue to contribute to CO2 emissions reductions and the prevention of global warming. Gradation blinds have been installed at Gakken Tokyo Headquarters since 2008. With these blinds, we are continuing CO2 emissions reductions by introducing appropriate light in rooms and reducing the heating and cooling burden by insulating rooms so that excessive changes in temperature are less likely to occur.
SYSCARE, which conducts planning, design and consulting services for elderly care facilities, provides support for improving the environmental performance of buildings by reducing energy consumption and CO2 emissions.
As of January 1, 2020, it has supported 61 applications for energy conservation measures and 161 applications for BELS evaluation, a system under which third-party organizations objectively evaluate and indicate the primary energy consumption of non-residential buildings.
It also provides consulting services for buildings that aim to achieve a zero annual primary energy consumption for a building by saving and creating energy while achieving a comfortable indoor environment (ZEB).
