Environmental Initiatives

Basic Approach

The Heiwa Real Estate Group considers its initiatives in environmental concerns as fundamental managerial issues and will promote the initiatives throughout its overall corporate activities. Giving full consideration to its responsibility to conserve the natural environment, the Group actively implements environmental initiatives while complying with environment-related laws and regulations.

Fighting Climate Change

Reducing environmental impact

To address environmental concerns (reduce energy use), Heiwa Real Estate's initiatives focus on resources (reducing costs).

Because office buildings require large amounts of energy to run, they are increasingly expected to offer high environmental performance. The Group gives top priority to the environment when constructing and renovating buildings, and also take steps to create a more attractive cityscape. Our approach helps to reduce the life-cycle cost of buildings through long-term use and to preserve historical value.

  • Controlling waste heat recovery with heat-recovery turbo freezers
  • Rooftop greening, solar heating, and utilization of rainwater
  • Open spaces secured and greenery maintained in open spaces surrounding the building in consideration of the scenery

Effectively Using Resources

Effectively using resources

1. Nisshokan Bldg.

At Nisshokan Bldg., to preserve these monuments that pass on the history and culture of Kabutocho, Tokyo’s “Securities District,” and ensure its sustainability, major energy conservation upgrades were carried out over a two-year period beginning in 2010.

Although the building was more than eighty years old at the start of the renovation, we worked to improve the building’s energy efficiency, ensure its continued usability, and benefit the neighborhood, so it would last a century.

2. Kabutocho Heiwa Building No. 5

With the goal of revitalizing the district and making it more attractive, the Group is reconstructing the Kabutocho Heiwa Building No. 5, which was built in Japan’s Taisho period (1912 – 1926), and changing its functions to increase its usage.
