Since April 1996, Yokohama City has been working to reduce the burden on the environment, such as the prevention of global warming and the prevention of air pollution, and to contribute to the realization of a safe city. We have implemented the “Guidelines” and are promoting the introduction of regional heating and cooling in the city.

What is regional heating and cooling?
It is a system that intensively manufactures cold water, hot water, and steam at a heat supply plant, supplies it to multiple buildings in a certain area using a conduit, and performs cooling, heating and hot water supply.
By combining them in one place without placing a heat source in each building, energy saving effects by improving operating efficiency can be obtained, as well as environmental impact such as utilization of unused energy, prevention of global warming, and prevention of air pollution. It can reduce the burden and is effective in creating a comfortable and efficient city.
