# District cooling

District cooling is a comfortable, safe and environmentally friendly way of cooling properties, using cold water circulated in a district cooling network in a similar way to district heating.

District cooling is available primarily in Finland’s largest cities, where a district cooling network already exists. It is a low-maintenance and reliable form of cooling: the district cooling substation requires little space and produces no noise, and there is no need for the property owner to maintain any cooling equipment of their own.

### Economical and environmentally friendly cooling

District cooling is often produced using waste heat, natural cold (e.g. sea water) and free cooling, which makes it an environmentally friendly and energy-efficient way of cooling buildings compared to conventional, electricity-consuming cooling systems.

Connecting a property to the district cooling network removes the need for the property’s own cooling machinery, freeing up technical space and reducing both investment and maintenance costs over the property’s lifecycle.
