consumption. With this in mind, we strive to be environmentallyfriendly in this business, aligning our activities to theenvironmental action plans and guidelines that we haveformulated. When developing new buildings, we adopt
environmental and energy-saving technologies forenvironmentally friendly buildings that are well-received bysociety. For existing buildings, we promote energy savings bystrategically renovating buildings using energy-saving
equipment. From an operating standpoint, we also collaborate
with our tenants to conserve energy and reduce
environmental impact.
We have set a quantitative indicator in the form of a power
consumption per floor area unit to reduce energy consumption.
Here, we target a 1% annual unit reduction averaged over five
years as a target in accordance with the Energy Conservation Act.

Senior Business 0.4%
Residential Business 3.4%

Among all Tokyo Tatemono business activities, the Commercial
Properties Business, which operates and manages officebuildings and commercial facilities, uses the most energy. Theenergy consumption of this business accounts for 92.6% of all
consumption within Tokyo Tatemono (calculation based on the
Energy Conservation Act*). Therefore, reducing the amount ofenergy used in the Commercial Properties Business results in a

Environmental Management in the Residential Business

Brillia Environmental Guidelines

In the Residential Business, we have a variety of creative
approaches to environmental management. We have formulated
the Brillia Environmental Guidelines, which systematize ourenvironmental initiatives. We have also established twoconcepts for the development of condominiums: “Creating
green lifestyles” and “Realizing homes with reduced
environmental impact (CO2 emission reduction).”The guidelines define a set of environmental performance
ratings with four levels of environmental friendliness. In addition
to the specifications required to meet each level, at each stageof the project from planning stage to design, we also checkdetails such as the environmental certification rankings (CASBEE,etc.) and CO2 emission reduction for each level.
We revise the guidelines periodically in response to socialchanges and technological advancements, and in this way
continue to increase the value of the Brillia brand.

Compliance with Environmental Laws and Regulations
In accordance with the Group Environmental Policy, we comply
with all laws and regulations related to the environment. When
executing new development projects in Japan and overseas,
we conduct the necessary environmental impact assessments(environmental assessments) in accordance with laws andregulations.
We experienced no environmental incidents or violations ofenvironmental laws or regulations in 2020.

Aim to achieve low-carbon residential buildings by proactively
adopting equipment and services that contribute to global
warming prevention and resource conservation.
Actively develop ZEH-M (Zech Mansion), which reduces
energy consumption by making the building itself highly
insulated and by using renewable energy.
Help reduce environmental impact throughout a building’s life
