Sustainability /
Efforts toward the SDGs

In addition to being selected for the Ministry of Land, Infrastructure, Transport and Tourism's 2021 Sustainable Building Leadership Project (CO2 Leadership Project), Grand Green Osaka has also acquired the following environmental certifications.

LEED-ND Gold Certification
(Planned certification)

We are also actively working toward contributing to SDGs through the following initiatives:

Reducing CO2 emissions

  • The first full-scale introduction of aquifer thermal energy storage*1 in Japan will reduce peak power consumption.
  • Biogas power generation*2 will significantly reduce the burden of waste disposal in general as well as the burden of carrying residual sludge out of the building, and will contribute to the creation of a decarbonized, circular economy for the city.
  • Efficient heating and cooling using sewage and geothermal heat will contribute to decarbonization.
  • Community air conditioning will also provide heat transfer between blocks of land and will contribute to improved energy efficiency of the entire city.

Contributing to Circulation of Water

  • The shade from vegetation and evapotranspiration from the plantings and water features will contribute to the microclimatic effects to create and control a cooler spot in the city center.
  • Green infrastructure technologies such as bioswales,*3 infiltration trenches,*4 and crushed stone reservoirs*5 will be utilized to facilitate underground infiltration of rainwater, thereby controlling runoff out of the area and contributing to controlling inundation by rainfall.*6
  • Recycling rainwater by using the planting base with its irrigation and storage functions will help to reduce water supply usage.

Considering Biodiversity

  • The birds and insects shown below have been determined as target species for the park based on an ecological survey of the Yodo River and Osaka Castle Park. The environment is being designed to consider habitat benefits of these species (control lighting levels, provide diverse and sequenced swaths of plantings from waterside to woods, etc.), aiming to contribute to the ecosystem network surrounding the Osaka city center.

Urban park doubling as a wide-area evacuation site

  • Umekita Park will be developed as an urban park which doubles as a wide-area evacuation site as part of the Urban Renaissance Agency's Disaster Response Park District Development Project at the request of Osaka City. It will accommodate temporary evacuees in the event of a large-scale disaster, such as an earthquake or fire.
  • The wide entrance configuration will allow for the smooth entry of temporary evacuees and emergency vehicles. It will also house disaster response facilities, such as emergency lighting, speakers, emergency portable toilets, and stockpile warehouses.
*1  :
Efficient building heating and cooling technology that extracts heat energy from water-rich sources underground (aquifers).
*2  :
Methane gas converted from organic kitchen waste and wastewater via methane fermentation. It is also a system which generates renewable energy by converting electricity and heat (hot water) through cogeneration.
*3  :
Landscaped depressions designed to collect and infiltrate rainwater during times of rainfall.
*4  :
Drainage facilities that are excavated trenches filled with crushed stone and lined with perforated pipes designed to evenly distribute the infiltrated water.
*5  :
Drainage facilities that direct rainwater into void storage and infiltration tanks of crushed stone, etc., and infiltrate the water into the ground from the sides and bottom.
*6  :
Urban flooding caused by insufficient drainage of rainwater into rivers and other channels in urban areas.

Grand Green Osaka seeks to contribute to 12 of the UN’s Sustainable Development Goals (SDGs)
