Solar Power Generation Panels
Solar power is generated into electric current by Solar Power Generation Panels which are placed on the roof, and they, together with other commercial power sources, are used for lights, office aquipment and other electric appliances.

Solar Absorption Panels
The air is warmed and remitted into rooms or brought into the airconditioning by Solar Absorption Panels, which are installed, on the roof, to help heighten the heating efficiency in winter.

Tree-planting on the rooftop
Tree-planting holps improve insulation of the roof and cool down the air coming into the building in the summer.

Insulation by movabie eaves and outer walls
Adjusting the angle of the eaves prevents direct rays from coming through windows in the summer. Making the outer concrete wall a power storage type, the outer walls can be used as outer air insulation. Multi-glazed windows improve insulatlon efficiency.

Cooling Tubes
Cooling Tubes, which pass through underground and rain water holding tanks, cool down the air and remit into rooms so as to let in the cool air during summer and mid-year.
Rain Water Holding Tanks
Rain water pouring on the roof is accumulated and held in a Rain Water Holding Tank, and used for watering plants in the premises and on the rooftop garden so that water conservation can be possible.
