With its advancements in energy-saving
technology, Japan has achieved one of
the world's highest levels of efficiency interms of energy consumption per unit ofgross domestic product (GDP).
At NIKKEN we have establishedenvironmental specialist groups, further
cultivating our technical expertise. Our
aim is to ensure user comfort andachieve net-zero energy consumption fora sustainable future.

Basic Concept or Summary
Green Technologies
The use of light shelves that block and diffuse direct sunlight and cast an abundance of indirect naturallight inside, vertical louvers for western sun screening, natural ventilation to draw outside air inside, airflow
windows to reduce the amount of radiant heat transfer through the windows, an atrium to provide natural
air circulation throughout the entire building, other devices such as NaS batteries,micro-gas turbines andphotovoltaic (PV) cells--our firm is dedicated to the development of new green technologies and creatively
innovative uses of conventional methodologies.

Effects or Remarks

O-20

Green technologies not only contribute to the environment, they are also conducive to the reduction of abuilding's life-cycle costs. For this laboratory, we employed the full spectrum of environmentally conscious
technology including the light shelf, vertical louver and natural ventilation. Through the effective use ofenergy and the forces of nature, we are reducing life cycle CO2 emissions by close to 40% and life-cycle
costs by close to 50%.

The powerful rays of the sun are countered byforming the windows as vertical slits 260cm high byjust 20cm wide ,to minimize the entry of light. Thethermal load is further reduced by the provision of aventilation space 8cm wide between the stones ofthe outer wall and the thermal insulation layer. Mostof the subdued illumination is provided by the indirectentry of light from the light court.
