Selection of Le Jade Okurayama as High-Rise ZEH-M Support Project

Achieving a balance between a comfortable interior environment and energy efficiency through the use of external walls with improved thermal insulation performance, double sashes with exceptional thermal insulation, and high-efficiency air-conditioning and hot-water supply facilities, this is an environmentally friendly real estate product that meets the ZEH-M Oriented standards stipulated by the Ministry of Trade, Economy, and Industry, which is the level that should be targeted for multi-family housing with 6 or more floors.

* ZEH (Net Zero Energy House) is a house aiming to make the annual primary energy consumption zero by introducing renewable energy after realizing significant conservation of energy while maintaining the quality of the indoor environment with significant improvement in the thermal insulation performance of the outer building skin as well as the introduction of a highly efficient equipment system.

Acquisition of DBJ Green Building Certification

The following community-based commercial facilities owned by ES-CON JAPAN REIT Investment Corporation (EJR) have acquired DBJ Green Building certification.

DBJ Green Building Certification is a certification system established by Development Bank of Japan (DBJ) in April 2011 to support environmentally and socially conscious real estate properties (“Green Buildings”). It supports these initiatives by evaluating and certifying socially and economically desirable properties based on a comprehensive assessment, which includes not only their environmental performance but also their responsiveness to various stakeholder needs, such as disaster preparedness and consideration of the community.

Two of the 4 properties in total that have acquired certification were developed by us, while operation and management of all 4 are handled by our subsidiary ES-CON Property.

Acquisition of CASBEE Real Estate Certification

We received the highest rank of “S” in CASBEE Real Estate Certification for “Soyoca Fujimino (Fujimino-shi, Saitama),” a logistics facility we own, from an assessment and certification organization of CASBEE certified by the Institute for Building Environment and Energy Conservation. Comprehensive Assessment System for Built Environment Efficiency (CASBEE) assesses and rates the environmental performance of buildings, and is a system for comprehensively assessing the quality of buildings including environmental consideration such as conservation of energy and the use of equipment with low environmental burden as well as consideration to indoor comfort and scenery.

CASBEE Real Estate Assessment was developed for the purpose of utilizing the results of the environmental assessments of buildings in CASBEE in real estate assessments. Buildings are scored in the five assessment items of “1. Energy and greenhouse gas,” “2. Water,” “3. Use of resources and safety,” “4. Biodiversity and site,” and “5. Indoor environment,” and one of the four ratings of “S,” “A,” “B+,” and “B” is given based on such score.

Introduction of Other Environmentally Friendly Equipment

We are carefully creating condominiums while considering the environment even at properties other than the ZEH-M condominiums which have particularly high environmental performance.

In the development of for-sale condominiums, we obtain the highest levels under the standards for performance of thermal insulation, etc. (grade 4) and deterioration (grade 3) as a standard.

We also seek effective utilization of energy and resources by employing LED lighting, water-saving toilets and other energy- and resource-efficient equipment.

  • High-efficiency TES (Eco-JOES)
  • Cogeneration system (ENE-FARM)
  • Water-saving toilet, heated bathtub, LED lighting, double glazing, emergency supply warehouse, etc.

Joint Research through Industry-Academia Collaboration

Joint Research with Tokyo University of Science

We are pursuing joint research with the Tokyo University of Science’s Takase Laboratory, which has a focus on architectural environment engineering, with the aim of reducing our environmental footprint and realizing a sustainable society through the development of environmentally friendly apartment buildings.

Research themes: Heat; Energy efficiency; Comfort; Global environment

[Tokyo University of Science Takase Laboratory]

Specializing in the field of architectural environment engineering, this lab is engaged in areas such as thermal environment, energy efficiency, and sustainable design. It has received numerous honors, including the 7th Sustainable Housing Award in 2017.

* Sustainable housing is housing that utilizes natural clean energy, such as solar power and wind power, without using energy from petroleum causing global warming.

Improvement of the Local Environment

For-Sale Detached Housing Rich in Nature

Park JADE Suginami Izumi has characteristic “garden paths” creating a continuous strip of space by placing greenery to make boundaries gradual and to blur the boundary line intentionally. Being able to sense nature no matter how limited the space and facilitating natural communication among residents will foster a community that forms and enjoys the effects of education in cultivation of sensitivity that would heighten the sensitivity of children.

Solar power is used to pump groundwater from Kanda River and the water flows along garden paths so as to create the sound of a stream. A hand pump is also installed to function as a means to secure water for domestic use in the event of a disaster or other emergency.

The living environment is one that enhances creativity and where children can learn about the power possessed by nature and the environment by being in close touch with greenery, water, solar energy, etc. in everyday life.

Park JADE Suginami Izumi won the 10th Kids Design Award in 2016.

For-Sale Condominiums Close to the Community

Le JADE Takatsuki was created by exploring the type of outdoor environment this place requires through a series of exchange of views with residents of the neighborhood with the aim of forming an urban space that would be loved by the community.

As a result, we managed to make the for-sale condominium’s outdoor environment one that achieves both “creation of open green space that enriches the community” and “forming of safe pedestrian space.” For the “creation of open green space that enriches the community,” we have provided greenery of a large scale at the intersection portion to contribute to forming a favorable cityscape as an oasis that enriches the lives of passersby. For the “forming of safe pedestrian space,” the adjacent sidewalk used to be narrow and the intersection at the northwest corner of the site saw frequent traffic accidents, but we have secured safety by forming a sidewalk-like open space on the site along the adjacent sidewalk, setting the existing sidewalk portion for bicycle traffic and setting the sidewalk-like open space for natural pedestrian traffic.

Winner of the 1st Takatsuki City Landscape Award in 2019.

Eco-Themed Renovation

We are undertaking renovation projects that can serve to curtail generation of waste material and save materials by making the most of existing buildings rather than “scrap & build” in these times that call for the promotion of environmentally friendly “eco”-themed business.

Environmentally Friendly Logistics Development

LOGITRES Tojo has been certified Rank A under the Comprehensive Assessment System for Built Environment Efficiency (CASBEE).

In addition, under our first solar power generation project, environmental considerations are being made at the property.

*CASBEE® is a tool for comprehensive assessment of the environmental performance of buildings, urban areas, cities, etc. from various perspectives, and is now widely utilized by building contractors, architectural designers, building owners, real estate investment institutions, etc. in Japan. There is also increasing utilization by some local governments as a reporting system.
