District heating is a system where heat is generated at a central location and then distributed through a network of insulated pipes to provide heating to multiple buildings or homes in a specific area. District cooling is a similar concept, but instead of distributing heat, it distributes chilled water to provide cooling to buildings in the district. Both district heating and district cooling systems are more energy-efficient and environmentally friendly compared to individual heating and cooling systems for each building, as they allow for centralized energy production and reduce overall energy consumption. **
