At Kashiwa-no-ha, we aim to build a futuristic city that harmonizes people and the environment, taking advantage of abundant natural resources to save, create, and store energy while deploying next-generation transportation systems and greenery programs to maintain secure lifelines, even during disasters.
Kashiwa-no-ha Smart City optimizes energy usage for the entire city. AEMS plays a pivotal role in this setup, drawing on an independently operated power grid and enabling area expansion as well as enhancing functions. This system is designed to contribute to smart grid progress that underpins lifestyles and innovations.
Planned layout of the completed Kashiwa-no-ha Smart Center (GATE SQUARE, Hotel and Residences on the 2nd floor)
The role of this facility includes overseeing energy operations for the area and managing energy information during disasters. The center monitors electricity usage in residences, commercial facilities, offices, and other locations and disseminates information to help people living and working in the area conserve energy effectively. The center also ensures electricity sharing following disasters. The complete oversight of this facility helps to make the city more environmentally friendly.
We began operating a smart grid that shares solar, storage cell, and other distributed energy sources among districts. We cut peak electricity consumption for the entire town by sharing one electric power company and distributed power between districts through private transmission lines. As daytime office electricity consumption increases on weekdays, LaLaport KASHIWANOHA supplies power to GATE SQUARE. On holidays, when the power demand of the shopping facility increases, Gate Square conversely supplies LaLaport KASHIWANOHA. This approach has enabled us to lower peak consumption by 26%, conserving energy and reducing carbon dioxide emissions.
We ensure security by drawing on renewable energy and storage batteries that can manage energy effectively during disasters. This setup makes it possible to deploy business and life continuity plans. In the event of a power outage, GATE SQUARE can supply 60% of the normal power requirements and maintain the supply for three days. It can also power emergency elevators, lights, and common areas in residential buildings. Water can be sourced through groundwater pumps.
HEMS displays energy consumption so residents can become more aware of their contributions to power conservation, thereby fostering environmentally friendly lifestyles. Dedicated tablets, personal computers, smartphones, and other devices show carbon dioxide (CO2) emissions from residences. This setup uses artificial intelligence for purposes such as advising on energy usage and ranking the effectiveness of energy-saving approaches. HEMS enhances disaster management through its demand response function, which solicits residents' help in using less power during emergencies. Residents can control lighting and air conditioning settings while away from home. (GATE SQUARE. at Park Axis, Kashiwa-no-ha)
We formulated a roadmap that constitutes a long-term vision for increasing comfort and reducing CO2 emissions. While keeping track of technological advances, we have embarked on steps to minimize our carbon footprint by lowering emissions by 60% by 2030.
Sustainable design reduces a dependence on electricity and other artificial energy sources by harnessing natural heat and air to lower the ecological impact. Two of the GATE SQUARE buildings encapsulate Japan’s world-leading green building technology. By combining the sustainable design and AEMS for each building in GATE SQUARE, we reduced CO2 emissions from these two buildings by about 40%, and lowered emissions for the shops and office buildings by about 50%.
We use solar panels, wind power equipment, well and rain water, and other renewable sources of energy. We aim to slash CO2 emissions by drawing on waste biogas, exhaust heat from cogeneration systems, and other untapped energy.
Plant factories employ advanced technology to stabilize food availability. Chiba University’s facility is the largest of its type in Japan, using natural and artificial light in high-yield production demonstration experiments.
Mitsui Fudosan is collaborating in the university’s Mirai agribusiness startup project, helping it progress toward commercialization.
