To provide a comfortable and highly efficient distribution center and office building, Atelier Ten worked closely with the local team to analyze strategies to reduce the building’s overall energy consumption.
The LEED Gold Landport Takatuski Distribution center is an active warehouse storage and distribution facility with supporting office and light retail spaces. Warehouses have high energy drivers due to their variable occupancy and activity that can lead to high operating costs. By dramatically reducing the interior lighting usage, and incorporating high efficiency HVAC measures, high performance envelope, and incorporating controls and sensors, the project achieved 46% energy consumption and cost savings compared to a baseline project.
The large warehouse storage portion of the building does not require high light levels, so the project selected LED fixtures that met the minimum lighting needs. For the mechanical strategy, the high efficiency variable refrigerant flow systems for heating and cooling was incorporated into the office area, and unconditioned make-up air brought directly into the storage spaces for ventilation as used according to the Japanese Building Code. Finally, the project strategically designed the glazing area and increased interior wall insulation where it was most needed in office and amenity spaces. Sensors and controls further reduce the energy usage in lighting, fan, and conditioning to the minimum required for the limited occupants.
