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 completed Kashiwa-no-ha Smart Center (GATE SQUARE Hotel and Residences on 2nd floor)
The roles of this facility are to oversee energy operations for the area and manage 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 between districts. We cut peak electricity consumption for the entire town by sharing 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 shopping facility power demand 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 battery 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 normal power requirements and maintain for three days. It can also power emergency elevators, lighting, and common areas in the residential building. 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, PCs, smartphones, and other devices show CO2 emissions from residences. This setup uses artificial intelligence for such purposes 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. (GATEWAY SQUARE at Park Axis Kashiwa-no-ha)
We formulated a roadmap that constitutes a long-term vision for increasing comfort while reducing CO2 emissions. While keeping track of technological advances, we have embarked on steps to minimize our carbon footprint by lowering emissions 60% by 2030.
Sustainable design reduces a dependence on electricity and other artificial energy sources by harnessing natural heat and air to lower ecological impact. Two GATE SQUARE buildings encapsulate Japan’s world-leading green building technology. By combining the sustainable design and Area Energy Management System (AEMS) for each building in Gate Square, we reduced CO2 emissions from the two buildings by about 40% and lowered emissions by about 50% for the shop and office building.
We use solar panels, wind power equipment, well-water 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.
A place for learning how to resolve local issues through community and university collaboration
Promotes environmental community activities that include environmental home economics and a project to visualize carbon dioxide emissions
