Mitsui Fudosan America and its affiliates are market leaders in environmentally-conscious real estate development and operations.  We are committed to social and economic development, as well as global environmental preservation under the principles of harmony and coexistence. The linking together of our “&” corporate logo and “EARTH” symbolizes Mitsui Fudosan’s commitment to sustainability and green initiatives, while acknowledging the planet as a shared community.



We strive to create healthy, high-quality, productive work and living spaces while simultaneously reducing energy consumption, reducing water usage, eliminating waste and reducing greenhouse gas emissions. As a company focused on long-term ownership, we develop flexible properties using high quality building materials and high-efficiency mechanical systems to reduce utility consumption, minimize repair and replacement costs, and to ensure our buildings remain competitive over the long term.


Design and Development

MFA is a corporate member of the U.S. Green Building Council and has a long history of owning, developing, and operating properties that are certified under USGBC’s Leadership in Energy and Environmental Design (LEED) rating system. LEED is a certification program that recognizes best-in-class building design, construction, operations and maintenance. Mitsui Fudosan America pursues LEED certification for all of our eligible office properties, since LEED is the most widely-recognized standard of environmental performance in the commercial real estate sector. MFA’s existing portfolio includes several LEED certified properties, and we are pursuing certifications on all office properties actively under development.

Energy Management

Managing energy consumption and implementing energy conservation improvements aligns with MFA’s objectives of reducing operating costs, benefiting our tenants and stakeholders, while also reducing environmental impact. MFA utilizes the U.S. Environmental Protection Agency's Energy Star program, energy management software and periodic energy audits to measure and monitor electricity, natural gas and steam consumption, as well as to ensure continual progress in limiting emissions of greenhouse gases. We replace and upgrade our energy management, building automation systems and environmental sensing equipment to ensure optimal performance. We purchase only Energy Star labeled equipment and appliances and we encourage our tenants to do so as well.


Whenever feasible we install high efficiency lighting in public spaces, corridors, stairways and elevators. We also utilize motion sensors to control lighting in many of our restrooms, garages and back-of-house areas to eliminate unnecessary consumption. Our new developments frequently incorporate features such as solar shades, high performance glass, and photo sensors to control lighting while reducing heat load.

Central Plant Improvements

MFA regularly examines the physical condition and performance of base building mechanical systems to determine if systems are operating efficiently, and to determine if modernization programs could save energy or improve building performance, air quality or tenant satisfaction. We frequently invest in capital improvements, including HVAC retrofits, compressor replacements, variable frequency drive retrofits and the installation of heat exchangers to improve building efficiency and performance.





MFA recognizes that transportation is a large contributor to greenhouse gas emissions and major consumer of fossil fuels. In response, MFA focuses on acquiring and developing properties in central business district locations offering excellent access to public transportation and within walking distance to a wide range of amenities. Our portfolio of office and residential properties has an average Walk Score® of 96 and an average Transit Score® of 95.

We encourage tenants and staff to consider alternative transportation. Many of our buildings provide secure indoor bicycle parking and changing facilities. We have installed electric vehicle charging stations at several properties to promote the use of electric and plug-in hybrid vehicles.

MFA recognizes the importance of water conservation, and we have upgraded plumbing fixtures across our portfolio with higher-efficiency toilets and faucets. In addition, several of our new developments include conservation-minded features, such as landscaped roof terraces, captured rainwater irrigation, rain sensors, and drought-tolerant landscaping.

Working in partnership with our vendors and tenants, MFA has implemented waste management best practices, including a solid waste management policy, single stream and e-waste recycling programs throughout our portfolio. We also have implemented a sustainable purchasing policy to reduce the consumption of products containing mercury and volatile organic compounds.


Indoor Air Quality

All MFA properties have a formal green cleaning requirement with their cleaning vendors to minimize the impact of cleaning products on the environment. Whenever possible, we use GreenSeal approved cleaning products, HEPA vacuums, and we stock restroom supplies made with recycled materials. When renovating space, we specify the use of LEED low-VOC, non-toxic paints and finishes.
