Measures for the Environment
The Tokyo Innovation Center was built to reduce our environmental footprint and preserve and blend in with its natural surroundings.
The building was awarded the "S Class" designation, the highest rank under the Comprehensive Assessment System for Built Environment Efficiency (CASBEE). Here we describe some of the Center's environmental features.
The Tokyo Innovation Center's Measures for the Environment
The Center uses renewable energy, achieving a 15% reduction in CO2 emissions.
The Center uses renewable energy, with solar energy generating 10% of the building's energy needs. By using energy-saving technologies like an ice thermal storage system that uses off-peak electricity, the Center has been able to reduce CO2 emissions by 15%* compared to ordinary research centers.
* According to a study by general contractor Shimizu Corporation.
The natural surroundings and site allow the Center to use natural energy, combining wind power and solar energy, to reduce its environmental footprint. The energy generated by the building's solar panels is used mainly to power the nighttime outdoor lighting system.
Solar panels, which convert solar energy directly into electricity, are installed on the second-floor roof and have an output of 85kw. Other energy-saving measures include the energy-efficient EcoCute heat pump, water heating and supply system using off-peak electricity, and an ice thermal storage multi-system powered by off-peak electricity, which contribute to reducing CO2 emissions.
"Fureai no Michi Path to the Future" Walking Trail
The Center is adjacent to the Utsunuki Green Zone, a nature conservation area. We have taken measures to preserve and blend in with the local ecosystem, for example, by transplanting saplings from the conservation area onto our property and ensuring that light does not reach a swampy area that is a firefly habitat. Employees have also gotten together to plant trees along the "Fureai no Michi" walking trail which winds through the woods.
The Center is located in Hachioji's Minamino City, a suburb designed to coexist with nature which has taken various steps to reduce the impact of development on the environment. Nissui employees volunteer for a tree-planting project and look forward to the future when the trees will have grown tall.
"Fureai no Michi"
Planting greenery on the roof helps keep indoor temperature lower in summer and prevents heat loss in winter. This can help cut down on heating and cooling costs and contributes to saving energy. A rooftop garden has been created on the terrace in front of the Center's fourth-floor lunchroom, which employees enjoy for relaxation.
Obtained the highest CASBEE environmental efficiency rating
The building was awarded the "S Class" designation, the highest rank under the Comprehensive Assessment System for Built Environment Efficiency (CASBEE). The Center is a model for an environmentally-adapted research center that blends in with the area's natural features.
Blending in with the Utsunuki Green Zone
The Center is adjacent to the Utsunuki Green Zone, a nature conservation area that preserves the nature of the Musashino region.
The trees and vegetation in this satoyama managed woodland constitute an ecosystem unique to the area. Nissui works together with the local community to help preserve and protect the zone's biodiversity.
