eco renewal project
renovation of the 40-year-old Shinryo headquarters
in Tokyo, Japan, aimed to make the building an
energy-efficient, comfortable working environment.
The building uses solar energy as well as energy-efficient equipment and leD lighting. The project
team created a duct and piping route installation
plan that maximized energy conservation and a
layout plan for equipment, lighting, desks, and
chairs to be implemented after renovation.
The building’s cooling and dehumidifying systems
were designed to provide comfortably cool air with
little humidity, even though room temperatures
were to be set at 28 degrees celsius during
summer months. The heating, ventilating, and air
conditioning system featured a highly efficient air
cooled chiller and heat pump with centrifugal fan.
Solar energy powered the solar cooling system, solar
hot water panel, and solar photovoltaic panels.
microStation’s 3D technology reduced the time
required to complete conceptual design by 200
man-hours. Verifying construction procedures
and consistency reduced ordering of unnecessary
materials by the equivalent of 100 man-hours.
The 3D model also saved 60 man-hours in time
spent explaining the design to contractors. post-renovation, the Shinryo headquarters used 40
percent less energy and produced 37 percent less
carbon dioxide exhaust.
