Daikin first with Platinum LEED award


JAPAN: Daikin’s recently opened Technology and Innovation Centre is the first large-scale office building in Japan to win LEED Platinum certification.

The new six-storey, 58,000m² facility opened last November in Settsu City, Osaka, at an estimated cost of €300m is the base for Daikin’s future technology developments in air conditioning, inverters, heat pumps, and refrigerants.

It was assessed for Platinum certification – the highest LEED award – based on the energy efficiencies achieved, the comfort of the indoor environment, and the planning involved for energy measurement and data collection. 

In particular, the certification recognised the building’s adoption of Daikin’s individual zone VRV air conditioning system and heat pump desiccant humidity control; its use of natural ventilation and natural lighting; use of solar energy, geothermal heat; detailed energy measurement and testing plans, third-party commissioning. It also gained points for the large scale use of rainwater and deployment of water conservation devices and the incorporation of native plants in the building.

Developed and managed by the US Green Building Council, LEED is a green building certification scheme for environmentally-responsible buildings and area development.

Additionally, Japan’s Comprehensive Assessment System for Built Environment Efficiency (CASBEE) awarded the Technology and Innovation Centre its highest level of S rank.
