Green Infrastructure Initiatives

Green infrastructure has been showing great promise as natural disaster risks increase, such as flooding from a greater number of local downpours caused by climate change.
Making the most of nature’s diverse functions, using green infrastructure not only helps conserve the natural environment but also provides a range of benefits, including boosting real estate value and revitalizing local communities.
Building on our extensive experience, we propose the use of green infrastructure across planning, design, maintenance as well as environmental education.

Minami-machida Grandberry Park

In the redevelopment project of this commercial facility, we constructed rain gardens and bioswales to help with disaster risk reduction. Rain gardens and bioswales are facilities that collect and temporarily store stormwater falling on the site, and let the water percolate into the ground.
On asphalt pavement, heavy rains cause stormwater to directly go through the sewers and flow into rivers and other waterways, causing flooding. Installing rain gardens and bioswales reduces stormwater runoff outside the site and prevents flooding.

The Park House Jiyugaoka Diana Garden

For this construction project, we implemented an ecologically conscious exterior greening and acquired certification from the Association for Business Innovation in harmony with Nature and Community (ABINC), a program that certifies biodiversity initiatives in office buildings, housing complexes and other land development projects.
After conducting pre-construction assessments of the natural ecosystem in the surrounding areas, we adopted a greening plan that takes the local ecosystem into account and created ecologically conscious green spaces that make use of existing trees and conserve sections of the soil to form the base of the ecosystem, among others. With the aim of serving as a resting place and feeding ground for Japanese tits and butterflies living in the surrounding areas, we planted tree species favored by these creatures, such as kuromoji (Lindera umbellata), camphor trees and azaleas.

Shibuya Scramble Square

In the urban area with few green spaces, we carried out a building wall greening project to provide valuable urban green.
Plants have been known to wither with higher wind speeds. However, there were a lot of unknowns about plant growth in the wind environment at upper stories of buildings, so we conducted experiments on several plants that simulate the wind environment at upper stories. Results showed that the common ivy grows well even under the vigorous wind environment of skyscraper stories, and we used it to carry out the wall greening at the upper stories of the building.
