Takenaka Corporation, Grappling with Environmentally-Friendly Construction as It Enacts “Connecting People with Nature” as Its Environmental Message

Publication of the “Environmental Concept Book: Target for 2050”

June 14, 2010Takenaka Corporation

Takenaka Corporation (President: Toichi Takenaka) has established specific enviromental concepts and long-term targets to be achieved by 2050. The company has also enacted the environmental message “Connecting People with Nature,” which shares these with Takenaka's clients and society as a whole. In doing so, we will promote long-term initiatives to achieve Environmentally-Friendly Construction, which is an approach intended to create a society capable of sustainable development.

By following the environmental message, Takenaka has defined the concept as, “Enhancing human sensitivity and creativity, and utilizing nature to achieve goals ranging from zero-carbon buildings(*1) to carbon neutral cities(*2),” in order to set and accept the challenge of energy reduction targets calling for zero-carbon buildings by 2030 and carbon minus buildings(*3) by 2050.

The “Environmental Concept Book: Aiming for 2050,” scheduled to be published at the end of this month, explains Takenaka's approach and a road map to the eventual achievement of the concept and long-term goals.

Takenaka Corporation will work to achieve its environmental concepts by actively developing environmental technologies and establishing environmental design and construction methods in order to unite people with nature through the creation of environmentally friendly spaces.

<From the Environmental Concept Book>

Zero-carbon buildings(*1)
Buildings which thoroughly conserve energy as they create their own energy to satisfy their total energy needs.
Carbon neutral cities(*2)
Creating carbon neutral cities and regions including off-site measures (two-way circulation of reusable energy, carbon credits, etc.)
Carbon minus buildings(*3)
Buildings producing their own energy and even supplying the surplus to surrounding buildings (because this approach also cuts CO2 emissions during construction or renovation of a building, it will achieve minus CO2 emissions over the building's life cycle).

Environmental Message

The environmental message was enacted with its goal, “Achieve construction that takes advantage of the natural forces of sunlight, water, and wind at the same time it enhances people's sensitivity and creativity, thereby narrowing the gap between people and nature.”

Environmental Concept

The environmental concept calls for the following activities:
Continue to construct buildings that improve people’s health, stimulate their; sensitivity and creativity, and let them live energetically, nurturing cultural diversity;
Take advantage of the latent power of nature;
Aim for buildings and cities close to nature as they conserve biodiversity and restore nature;
Simultaneously minimize their impact on nature;
Lower the life-cycle carbon emissions of buildings to zero (by creating zero-carbon buildings,).
Aim to create carbon neutral cities and regions in the future by forming energy networks in cities and regions, and obtaining energy from reusable energy sources to harmonize supply and demand for energy among buildings.

Long-term Goals (Target reduction of energy consumed during operations by 2050)

Takenaka Corporation will inaugurate a zero-carbon building pilot project in 2020 to achieve zero-carbon buildings at the operating stage as a best-practice for buildings newly constructed in 2030 (state-of-the-art buildings), and to achieve carbon minus buildings throughout the life cycle of buildings, including CO2 emissions during construction as the best practice for buildings newly constructed in 2050.
