The Sapporo Sankei Building is a showroom of diverse technologies that proposes element technologies and their operational methods aimed at achieving a ZEB (Zero Energy Building) in a cold climate. By adopting high-performance exterior walls and windows to minimize loads, energy-saving equipment and systems are introduced. This significantly reduces the building's primary energy consumption while ensuring comfort. Additionally, by utilizing the characteristics of renewable energy, performance verification is appropriately conducted through simulations, trial operation adjustments, and tuning, maximizing the building's ZEB performance along with visualization. **Features** - Reception Room: An air-based radiant air conditioning system reduces temperature unevenness and discomfort from airflow. - Office: A water-based high-efficiency radiant air conditioning system pursues comfort and energy savings. - Hall: A visualization monitor is installed to enhance users' energy-saving awareness. - Refresh Corner: A communication space for improving intellectual productivity. - Air Conditioning Machine Room: Energy savings are achieved through hybrid operation of water and air heat sources. *For more details, please refer to the PDF materials or feel free to contact us.*

【Other Features】 ■ Stairwell with Atrium: By creating an atrium in the stairwell, natural ventilation, air circulation, and daylight utilization are achieved. ■ Mechanical Room: Actively utilizes geothermal energy as an air conditioning heat source to reduce CO2 emissions. ■ Central Monitoring Room: Manages the energy of the entire building using the Sanken Smart BA System. ■ Rooftop: Equipped with multi air conditioning units designed for cold climate buildings. *For more details, please refer to the PDF materials or feel free to contact us.

[Achievements] ■ Achieved Nearly ZEB in the fiscal year 2021 *For more details, please refer to the PDF document or feel free to contact us.*
