Reduce CO2

Specifications for Reducing CO2 for For-sale Condominiums

Mitsui Fudosan Residential Co., Ltd. is introducing 5 specifications for reducing CO2 for its for-sale condominiums, such as the Park Homes, or Park City Series. These are: 1) the “Eco Glass (Low-E multilayer glass),” which has excellent heat shielding performance and heat insulation capacities, 2) the “Uchimizu” block (Uchimizu is normally the act of sprinkling water on streets to control airborne dirt or ease heat), which possesses permeability and a water-retaining function, 3) high efficiency hot-water units called "Eco Jozu" and “Eco Cute,” 4) Save Earth Display units which help people visualize their CO2 emissions, etc. and 5) “Eco Lighting.”
Additionally, we are actively working to introduce solar power generation which uses natural energy, and are actively carrying out measures to reduce CO2 emissions from privately-owned vehicles, as well as other activities.

Promoting the Visualization of CO2 Emissions, etc.

Visualization of CO2 emissions and energy consumption is said to raise the effectiveness of energy conservation. Mitsui Fudosan Residential Co., Ltd. is promoting the visualization of CO2 emissions, etc. primarily in properties located in the Tokyo metropolitan area by installing Save Earth Display units, which it developed in cooperation with Tokyo Gas Co., Ltd.

LED Illumination Also Fitted in All Houses as Standard Equipment

At Park Homes Roka Koen Airy Court (Setagaya-ku, Tokyo), we not only fitted LED illumination in the common-use areas as standard equipment, but also in all houses as standard equipment. This is the first for-sale condominium of the Mitsui Fudosan Group to fit LED illumination in all houses as standard equipment. Fitting LED illumination as standard equipment was decided based on the results of a questionnaire survey that was implemented targeting home purchasers at the community website for residences and living, “Minnano Sumai (Everyone's Residence)” which is operated by Mitsui Fudosan Residential Co., Ltd.

Introduction of Solar Power Generation

Park Homes Roka Koen Airy Court, Park City Minami Senrioka (Settsu-shi, Osaka Prefecture), Park City Kashiwanoha Campus Nibangai (Kashiwa-shi, Chiba Prefecture) and Park Homes Todoroki Residence Square (Setagaya-ku, Tokyo) installed solar power generation systems.

Overview of Solar Power Generation at Each Condominium Complex

Facility Name Place where Solar Panels Have Been Installed Electrical Generating Capacity Use of the Power that was Generated
Park Homes Roka Koen Airy Court Rooftop Approx. 3.33kW Common-use area
Park City Minami Senrioka Rooftop of the gymnasium (common facility) Approx. 10kW Common-use area
Park City Kashiwanoha Campus Nibangai Rooftop Approx. 20kW Common-use area
Park Court Todoroki Garden Square Rooftop Approx. 6.24kW Air-conditioners in common-use areas

Reduction of CO2 Emissions Arising from Privately-Owned Vehicles

The Mitsui Fudosan Group is contributing to the reduction of CO2 arising from privately-owned vehicles by introducing car sharing using the eco-vehicle or by introducing rental bicycles. Furthermore, at Park Homes Todoroki Residence Square, we are planning to establish a recharging station for electric vehicles.

Progress of Measures to Reduce CO2 Emissions Arising from Privately-Owned Vehicles at Each Condominium Complex

Facility Name Rental Bicycles Car Sharing of Eco-vehicles Recharging Station
Park Homes Roka Koen Airy Court 8 electric bicycles - -
Park City Minami Senrigaoka - 1 electric vehicle and 1 hybrid car 1 station (200V)
Park City Kashiwanoha Campus Nibangai 30 electric bicycles and 30 self-propelled bicycles 2 hybrid cars and 1 fuel-efficient car -
Park Court Todoroki Residence Square 4 electric bicycles 1 fuel-efficient car 1 station (200V)

Specifications for Reducing CO2 for Rental Condominiums

At Mitsui Fudosan's rental condominium named the Park Axis Series, we are furthering the provision of housing which have specifications for reducing CO2, including the increase of heat insulation capacities, introduction of energy-saving or high-efficiency facilities, such as LED illumination, etc.

Installation of LED Illumination

At Park Axis Komagome (Toshima-ku, Tokyo) and Park Axis Itabashi Honcho Nibankan (Itabashi-ku, Tokyo), we have also installed LED illumination in common-use areas.

Specifications for Reducing CO2 for Detached Houses

At for-sale detached houses of Mitsui Fudosan Residential Co., Ltd., the introduction of “Eco Glass (Low-E multilayer glass),” “Eco Jozu” and “Save Earth Display” units are being carried forward in the Tokyo metropolitan area. Simultaneously, the provision of housing which meet the Top Runner Standards prescribed by the Energy Saving Law(*1) has begun from September 2010.

(*1) Housing which meet the Top Runner Standards: In addition to exterior walls and windows meeting Next-generation Energy Conservation Standards, residential properties are sought to reduce energy consumption by roughly 10% in comparison to that of residential properties which have installed conventional facilities as of fiscal 2008 (air-conditioners, lighting, hot-water units, etc.).

Specifications for Saving Energy for Custom-built Detached Houses

Standard specifications for custom-built detached houses of Mitsui Home Co., Ltd. exceed the Next-generation Energy Conservation Standards(*2). The company employs roofs using 6-inch, double shield (DS) panels with superb heat insulation capacities, an originally-produced, highly durable wet-construction base for exterior walls called the BS Wall, and others. Furthermore, it is striving to promote the installation of high efficiency hot-water units or solar power generation systems. In addition, the company is striving to meet individual requests of customers, such as household fuel cells.

(*2) Next-generation Energy Conservation Standards: Refers to the “Judgment and Standards of Construction Clients related to the Rational Use of Energy pertaining to Residences” and “Designing and Construction Guidelines” of the same, that were revised in March 1999. The revisions primarily calls for the increase of heat insulation capacities and air leakage efficiency.

ECO Challenge for Residences

In June 2010, Mitsui Fudosan Residential Co., Ltd. opened a website named “Eco Challenge for Residences” which supports eco activities for daily household life.
The “Eco Challenge for Residences” website has prepared an “Environmental Housekeeping Book” which automatically calculates the volume of CO2 emitted by inputting into a certain screen the volume of electricity, gas, water, etc. used every month. At the website, an individual's past record, etc. can be indicated by use of a graph. By visualizing CO2 emissions this way, we are aiming to promote CO2 reduction activities. Furthermore, by overcoming certain eco challenges established every month, “Eco Peace” points are granted which can be exchanged for ecology-related products. We are incorporating techniques to allow participants to lead a fun “ecological” and “economical” life while holding communication with each other by displaying the environmental contribution ranking among participants and posting their comments, among other things.

Topics: Selected as a Model Project for Promoting Low CO2 Emissions (Park Homes Todoroki Residence Square)

The Mitsui Fudosan Group designed the for-sale condominium, Park Homes Todoroki Residence Square*3, based on four CO2 reduction perspectives. In addition to the adoption of solar power generation or heat insulation that meets the Next-generation Energy Conservation Standards, we visualized energy consumption through Save Earth Display units, issued Green Power Certificates and established the MFR Eco Club to grant points for eco activities. Based on such perspectives, we are planning to create a system for promoting eco activities by residents.
Such activities in the areas of both building facilities and building operations were well evaluated and it was adopted as one of the Ministry of Land, Infrastructure, Transport and Tourism's “2009 (2nd) Model Project for Houses and Buildings that Promote Low CO2 Emissions”.
