3 Harumidai Project (Osaka Prefecture) POINT Japan’s first Net Zero Energy Town (FY 2013) Accomplished Net Zero Energy Town by producing more energy by PV (3,803GJ/year) than the amount of energy consumed (3,461GJ/year) . 111% greater energy produced by PV. This smart city includes PV＋Li-Ion Battery, Fuel Cell or CO2 Heat pump water heater for ZEH.
(Subsidies included) 17.1kW PV on balancing 2.5kW PV tank 14.7kWh LiB* Meeting house
●All houses include ・5.0kW photovoltaic power system ・Li-ion battery system
・Fuel cell system or CO2 Heat pump water heater 5.08 kW PV ・D-HEMS system *LiB: Lithium ion battery average →Net Zero Energy House (ZEH) 4 Eliiy Power Lithium Ion Battery POINT Safest Storage Battery installed in houses Daiwa House is the largest stakeholder. Top priority of this battery is “safety”. Eliiy power battery cell is the only company certified by world widely known organization “TÜV Rheinland”. Long service life is guaranteed, boasting an 80.1% capacity retention after repeated use for 10 years. ● Storage battery product For Houses For commercial and office
Power YILLE 3 Power iE5 Link Power Storager 10 5 Hidamarino Oka Project (Mie Prefecture) POINT Second Net Zero Energy Town (FY 2014) First in Japan to use electric power revenue from PV for management of the town. Achieving Net Zero Energy Town by installing 100kW PV on the slope of the town reducing the initial cost by minimizing the PV on each houses.
(Subsidies not included) 3.0kW PV on all houses
100kW PV on the slope of the town
100kW PV

Designed to increase the self-consumption rate by producing and consuming the energy at the same site. By interchanging electric power, self-consumption of PV in this town has increased compared to Harumidai.

Organized energy visualization system between houses, condominiums and commercial stores. Enforced the “Cool Share” and in case of earth quake, electricity will be supplied from commercial store to condominium.
Single-Family Condominiums Houses
PV, fuel cell, storage battery is installed in 80% of the houses

Visualization system 8 King Skyfront Project (Kanagawa Prefecture) POINT World’s first Hydrogen Hotel (FY 2018) Operated by using the hydrogen originated from wasted plastic from neighborhood facility. Hydrogen originated from waste plastic is non CO2 emitting energy. This experiment will affect the future of infrastructure weather delivering hydrogen by pipeline is possible.
Now only used for the departure, but will be used for landing for the Tokyo Olympics Paralympics
