Established January 2011


Tokyo Tatemono Group has built a management system that matches the characteristics of each business, an office buildings business that engages in the construction and management of buildings, and a development business that engages in the development of the Brillia brand and other housing under the Group Environmental Policy. In other businesses and Group companies, business is conducted considering the environment by formulating environmental guidelines for each business based on the Group Environmental Policy.

Environmental Management of Office Buildings

In the business activities of Tokyo Tatemono, the Office Buildings Business that operates and manages office buildings (commercial) uses the most energy. The ratio of energy use makes up 93.9% of Tokyo Tatemono (calculation based on the Energy Conservation Act*). Therefore, reducing the amount of energy used in the Office Buildings Business largely contributes to the reduction of the total amount of energy use at Tokyo Tatemono.
In the Office Buildings Department, we have formulated an environmental execution plan based on a high awareness of energy conservation with consideration to the issue of climate change and strive daily in energy-saving activities. We actively adopt environmental energy-saving technologies in the development of new buildings for the purpose of building environmentally-friendly buildings praised by society. In existing buildings, we promote energy savings by strategically renewing the buildings with energysaving equipment in addition to efforts to save energy from an operational perspective and reduce the environmental impact with the help of tenants.
Moreover, in the reduction of energy consumption, we have defined unit consumption based on floor area as an indicator and set 1% unit reduction every year on average over five years as a target in accordance with the Act on the Rational Use of Energy (per unit basis also applies to GHG emissions)

Environmental Management in the Residence Business

In the Residential Development Department, we are formulating Environmentally Conscious Housing Guideline that systematized our environmental measures to promote considerations toward the environment and improve the brand value of Brillia. We design individual properties based on these guidelines for residential development and strive to reduce the environmental impact. These guidelines continue to be revised according to social changes and technological advancements.

Brillia Environmentally Conscious Housing Guideline

Three Concepts Underlying All Things

Condominiums are diverse in size, life of the building, and the materials used, which have a large impact on the environment and a wide range of distinct countermeasures. Therefore, we have put in place three concepts to Think Green, Think Lifestyle, and Think Future to incorporate in the entire Brillia series.

  • I Think Green ― Green & Cool residential spaces filled with greenery: Setting up green spaces acts as a heat island countermeasure and brings about a rich natural environment friendly to the ecosystem.
  • II Think Lifestyle ― Introduction of high-efficiency green residential equipment: High-efficiency equipment comfortably saves energy and contributes to disaster prevention in case of an emergency.
  • III Think Future ― Eco Life Cycle Improvement Plan for Energy and Greenery: Resident participation in operation and management as well as community development will continue in a cycle with concepts I and II.

Ratings for Environmental Performance

Level 1 and Level 2 have been set as two levels for environmental performance to objectively judge at what level a condominium satisfies environmental performance.
Each level is equivalent to housing performance evaluation systems and evaluated by acquiring CASBEE® and the Tokyo Green Labeling System for Condominiums.
We also put in place optional specifications for even greater consideration toward the environment.
