"Haseko Corporation held a press tour on the 31st to commemorate the completion of the rental condominium 'Sustainable Ranche Hon-Gyotoku' (36 units in total) located in Ichikawa City, Chiba Prefecture.
Situated a 6-minute walk from Myoden Station on the Tokyo Metro Tozai Line, the condominium is a renovation of a company-owned dormitory that was over 30 years old, transformed into a five-story reinforced concrete rental condominium. The site covers an area of 1,651.83 square meters with a total floor area of 3,071.06 square meters.
Improvements such as enhancing internal and external insulation performance and upgrading to Low-E double-layer glass and vacuum glass using a cover method were implemented. The existing electric and gas infrastructure was converted to all-electric, and solar power generation facilities were installed on the rooftop (18 kW), walls (0.68 kW), and glass handrails on the fifth floor (1 kW). Measures such as adopting hydrogen fuel cells and introducing a self-consumption system for solar power generation using a central eco-cute were implemented to aim for virtually zero CO2 emissions during building operation.
The existing driveway was renovated into an entrance lounge, incorporating facial recognition systems and auto-locks. In the entrance hall, a welcome display linked to motion sensors using organic EL lighting was installed. The exterior was renovated by installing a metal framework over the existing tiles and applying siding. The property area is designated as a hazard map area (0.5 to 3.0 meters) during Edo River flooding, and rainwater storage tanks were installed in a dedicated garden to prevent flooding during heavy rainfall. The existing air conditioner outdoor unit storage area was renovated into a locked storage space.
Thirteen experimental units are available in the condominium. These units include a 'Home for Good Sleep' to verify the impact of lighting control synchronized with lifestyle rhythms on improving sleep quality, an 'IoT+AI Smart Housing' to promote research and technological development towards creating future homes that are all AI-controllable, and a 'Theater Room' with soundproofing to verify the acoustic performance required for theater viewing. Employees of the company group will live in these units while collecting 'living information' to develop new products and improve technology and performance.
The average floor area of the units is 70 square meters. Currently, rent considerations are underway, and recruitment of residents for units other than experimental ones is scheduled to begin around November.
Tetsushi Wakabayashi, Executive Officer of the Company's Technology Promotion Division, stated, 'In this property, we have installed solar power generation in three locations to achieve energy savings in residences and virtually zero CO2 emissions through renewable energy. In December 2021, we established a climate change response policy with a goal of reducing CO2 emissions, aiming for carbon neutrality by 2050 as a group-wide effort. We will continue to contribute to the realization of a sustainable society.'"
