Mitsui Fudosan Group not only provides energy-saving buildings but is also conducting energy-conservation activities and activities to decrease CO₂ emitted during the management operations of its buildings.

Mitsui Fudosan Group is working on energy conservation activities in our daily business activities by turning lights off during lunch break, turning off lights or automated office equipment when they are not being used, changing the setting of room temperature during summer and winter seasons, and implementing the Cool-Biz Campaign.
In fiscal 2008, in response to the implementation of “Eco-work Month” (August) (*3) by the Nippon Keidanren Secretariat, we implemented zero overtime work days during the same period. We also participated in the Light-Down Campaign of the Ministry of the Environment.

(*3) Eco-work Month: With the goal of realizing the reduction of energy consumption and work-life balance, the Nippon Keidanren Secretariat is introducing Eco-work Month for the month of August, which is the voluntary implementation of summer time (working hours: 8:30 a.m. to 4:00 p.m.).

Mitsui Fudosan Group implements construction targeting to reduce CO₂ emission by introducing energy conservation measures and other measures.

Office Building Construction Targeting CO₂ Reduction

We implemented construction targeting CO₂ reduction for approximately 50 office buildings in fiscal 2008. For example, we introduced high-efficiency lighting, controlled the volume of external air from air conditioners and parking spaces, installed inverters in air-conditioners, introduced heat shielding films and heat insulation measures for steam piping, etc. By implementing such constructions targeting CO₂ reduction, we are estimating a reduction of CO₂ emission of approximately 700 tons annually.

Retail Property Construction Targeting CO₂ Reduction

When it was necessary to renew gas heat pump air conditioners during fiscal 2008 at MITSUI OUTLET PARK Tama Minami Osawa (Hachioji-shi, Tokyo), we exchanged all 110 gas heat pump air conditioners in stage 1 buildings to more efficient ones. We are estimating a reduction of CO₂ emission of approximately 520 tons annually.

For the Whole Earth and for Everyone: “Eco Hello!” Activities Developed by Retail Properties

To systematically reduce CO₂ emissions during management operations of existing office buildings, the Office Building Business Division promotes discussions on measures to improve operations based on energy-saving diagnoses, verifies construction targeting CO₂ reduction and managing CO₂ emission data.

Discussion and Implementation of Measures to Improve Operations

In fiscal 2008, we implemented energy-saving monitoring surveys for three buildings (*5) that were given energy-saving diagnoses in fiscal 2007 as well as seven buildings that were given the same diagnoses in fiscal 2008, based on the results of these diagnoses. Furthermore, for 250 office buildings nationwide that Mitsui Fudosan Group carries out management operations, we implemented surveys on the implementation status of energy-saving management operations and energy conservation construction. Based on these results, we discussed and formulated operation improvement policies.
In fiscal 2009, we plan to formulate plans to improve operations for each property and then implement measures to improve operations.

(*5) 3 Buildings: Refers to Yaesu Mitsui Building (Chuo-ku, Tokyo), Jimbocho Mitsui Building (Chiyoda-ku, Tokyo) and Shin Kawasaki Mitsui Building (Saiwai-ku, Kawasaki-shi, Kanagawa Prefecture).
(*6) 7 Buildings: Refers to Nihonbashi 1-chome Building (Chuo-ku, Tokyo), Toranomon Mitsui Building (Chiyoda-ku, Tokyo), Nishi-Shinjuku Mitsui Building (Shinjuku-ku, Tokyo), Toranomon Kotohira Tower (Minato-ku, Tokyo), Gate City Ohsaki (Shinagawa-ku, Tokyo), Nihonbashi Mitsui Tower (Chuo-ku, Tokyo) and Ginza Mitsui Building (Chiyoda-ku, Tokyo).

Verifying Construction Targeting CO₂ Reduction for Facility Equipment

In fiscal 2008, we made mandatory the estimation of the volume of CO₂ emission for the period after completion of construction before beginning to carry out construction targeting CO₂ reduction. The purpose is to enable the verification of the accuracy of estimations of the volume of CO₂ emission. Furthermore, we conducted a simulation of the medium-term construction plan for the period between fiscal 2009 and fiscal 2012. This was a simulation of the reduction volume of CO₂ emission and costs in the case of carrying out construction for construction items that are highly effective in reducing CO₂ emissions based on the ability of existing office buildings to make such responses and the scheduled renewal periods of applicable facilities.
In fiscal 2009, we are planning to compare and analyze the estimation results and actual results of CO₂ emissions to improve the accuracy of estimations and then reflecting these in plans for construction targeting CO₂ reduction by establishing a management system for construction targeting CO₂ reduction. From fiscal 2010 to 2014, we are planning to formulate an implementation plan for construction targeting CO₂ reduction and to verify the effect of reducing CO₂ emission before and after carrying out construction.

Management of CO₂ Emission Data

In fiscal 2008, we summarized the data on volume of energy used and calculated the volume of CO₂ emission during fiscal 2007. Furthermore, we ensured the thorough input of data into summary systems and picked out issues concerning summaries, etc.
As a result of revisions made to the Energy Saving Law (*7) and Ordinance of the Tokyo Metropolitan Government (*8), a company is required to investigate the volume of their own emission and disclose data of the volume of energy used to tenants. In fiscal 2009, we plan to discuss how we may efficiently and accurately summarize the entire Company's volume as well as the calculation method for the volume of energy used for air conditioning by each tenant. In addition, we plan to discuss a more efficient method of summarizing with the aim of creating a database of the volume of energy used (formulation as a system).

(*7) Energy Saving Law: A law concerning the streamlining of the use of energy. It was revised in 2008 and each business (company) was newly required to manage energy. (*8) Ordinance of the Tokyo Metropolitan Government: Tokyo Metropolitan ordinance on “Environment for Protection of Resident Health and Safety.” It was revised in fiscal 2008 and newly required large business offices in Tokyo to reduce the total emission volume of global warming gases. It also introduced an emissions trading system.
