Office Environmental Initiatives

Eco-friendly Office Buildings

Being a dynamically growing company, in 2008 Akebono completed the construction of ACP (Akebono Central Pier) - a new office in Chubu region. The office building is equipped with an air-conditioning system utilizing subterranean water to reduce CO2 emissions.

Another eco-friendly office building completed in the same year - our new Global Headquarters in Nihonbashi, Tokyo - was equipped with roof-mounted solar panels. They generate enough electricity to power three elevators during the day. The building also uses rainwater for toilet flushing, which allows us to save more than 1,300 tons of water per year (which is equal to roughly 10% of our total general service water usage). In addition, glass panels with excellent insulation properties (low emissivity or low-e glass) are used on the eastern face of the building to improve thermal efficiency of the building and help reduce CO2 emissions.

Apart from the above, multiple environmental initiatives are being undertaken in all our locations to reduce energy usage and carbon dioxide emissions. Please refer to “AKEBONO REPORT” for details.

Ai-City certified as a Semi-Top-Level Office in the Excellent Large-Scale Business Facility in Saitama Prefecture

Ai-City (Headquarters) in Hanyu, Saitama Prefecture was certified as a Semi-Top-Level Office in the Excellent Large-Scale Business Facility category, under Saitama Prefecture’s cap-and-trade emissions trading system for conducting outstanding measures to reduce the volume of CO2 emissions. The certificate was issued in April 2017.

To reduce CO2 emissions associated with business activities, Saitama Prefecture introduced the cap-and-trade emissions trading system from fiscal 2011. Business sites that implement especially effective initiatives are designated as “Top-Level Office” and “Semi-Top-Level Office.”

For some time now, Akebono has been engaged in energy-saving activities. Among other initiatives, we use power generation facilities that make use of waste heat and waste hot water, made our lighting more efficient by using solar power generation, and made our energy use visible with a building energy management system.

Awarded Judging Committee’s Special Prize at Energy Conservation Awards

At the Fiscal 2015 Energy Conservation Awards (energy conservation practices category) sponsored by The Energy Conservation Center, Japan (with support from the Ministry of Economy, Trade and Industry), Akebono won the Judging Committee’s Special Prize for initiatives to maximize efficient utilization of cogeneration systems in office buildings.

The Energy Conservation Awards recognize the activities of enterprises in Japan promoting energy conservation or developing products with exceptional energy efficiency. The awards seek to raise awareness of energy conservation further, promoting energy efficient products, developing energy efficient industries, and helping to build a more energy efficient society. The award was made in recognition of the energy conservation and generation initiatives being conducted at Ai-City (headquarters and R&D site), which include the following.

  • Introduced steam-powered binary generators and compressors with installation of gas engine generators and waste gas boilers, and increased generating efficiency by fully utilizing waste heat (steam) from gas engine generators using binary power generation
  • Utilized renewable energy including solar-powered hot water facilities and photovoltaic power generation
  • Reduced solar radiation load by coating roofs with a thermal barrier
  • Made energy use visible through use of a building energy management system (BEMS)
  • Increased efficiency of air conditioners
  • Increased efficiency of lighting

 Through these initiatives, Akebono has reduced energy consumption by 1,034 kiloliters per year on a crude oil-equivalent basis and 1,603 tons year on a CO2-equivalent basis.

Received Honorable Mention for the 2017 Cogeneration Grand Prize

In February 2018, at the Cogeneration Grand Prize 2017 sponsored by the Cogeneration Foundation (Advanced Cogeneration and Energy Utilization Center Japan), Akebono received an Honorable Mention (in the Industry Category) for “Improving efficiency and reducing greenhouse gas emissions through cogeneration systems”).

Since the introduction of cogeneration in 2011, Akebono has been building systems to reduce CO2 emissions by improving overall efficiency with the goal of daily capacity utilization, cutting electric power supply to the outside during peak hours, contributing to the electric power business by combining the introduction of advanced equipment that utilizes waste heat with renewable energy, as well as consistently raising gas engine power generation efficiency and improving waste heat utilization efficiency.

Akebono also received the Excellence Award at the Cogeneration Grand Prize 2013, this time receiving its second award. To fulfill its corporate social responsibility, Akebono views global environmental problems as one of its most important management challenges and is working more comprehensively on environmental conservation activities from a global perspective.
