Keywords: Climate Change Eco-business / Social Venture Environmental Technology Non-manufacturing industry 

Mitsubishi Estate Co., a major Japanese real estate company, announced on April 26, 2012, that it would start construction of an environmentally friendly office building in Kayaba-cho, Chuo Ward, Tokyo, on June 15. The "Kayaba-cho Project (tentatively named)" aims to develop an eco-friendly model building featuring leading-edge eco-friendly technologies. Mitsubishi Estate intends to accumulate verification data from tenant companies while they use the office spaces, hoping to utilize the data to build an even larger office building.

The major technologies to be introduced are an intelligent lighting system and a hybrid radiant air-conditioning system. For the former, an individual office worker sets his/her own optimum lighting intensity,, color and temperature into his/her personal computer in the office, and then artificial intelligence will control lighting conditions to provide the optimum conditions for all workers. The latter system is a fusion of a radiant air-conditioning system using heat-transfer between objects of different temperatures and the building frame heat storage structure in which building frame itself stores cold energy.

Mitsubishi Estate will be introducing these technologies in a complex form for the first time in Japan, which will result in a reduction of electricity consumption from lighting and air-conditioning, which are the two major sources of power consumption office buildings. With two other environmental technologies, the bi-level natural ventilation system and the eco-grid system (insolation shielding louver), the company expects that the new building to reduce energy consumption by about 45 percent (CO2 equivalent) compared with an ordinary office building.
