District Heating & Cooling System

Capital Cooling District cooling is up to 10 times more efficient than conventional cooling technology. Centrally produced, and often based on natural cooling from the cold bottom water of lakes, ground water, rivers, the ocean, or from conversion of waste heat or bioenergy through absorption technology, district cooling is delivered to buildings via water at 6°C in a closed, in-ground pipe system.

After performing the cooling service, the energy content of the now 16°C water can be recycled for use in a district heating system to provide heat and domestic hot water.

The main idea behind district cooling is to use local sources for cooling that would otherwise be wasted or not used, in order to offer the local market a competitive and efficient alternative to conventional products. Capital Cooling’s unique set of partnerships with Swedish technical consultancies, contractors, and operations companies, makes the company well positioned to take on district cooling projects of any size, from housing projects to hospitals, airports to shopping malls, and university and industrial campuses.

Capital Cooling’s clean-tech concept “The Cleaner Environmental Solution” has received well-deserved attention from the Global Focus 12 Bill Gates Project, as well as being one of the C40 Cities’ (18 leading world cities joining forces in order to tackle global warming and climate change) “Best practices.”


District cooling is a local, sustainable solution to global cooling needs. In Europe, roughly 40% of all commercial and institutional buildings are equipped with some kind of climate control for comfort cooling. In the US and Japan, this figure is about 80%, and the demand for cooling systems in nations like China and India is increasing rapidly. District cooling makes possible the large-scale leveraging of natural cooling and the delivery of this cooling in an energy efficient manner. This entails major climate benefits.

Decreasing energy consumption means lower carbon dioxide emissions and a smaller climate impact. In Stockholm, Sweden, Capital Cooling has constructed systems for district cooling that have reduced emissions from 280 gCO2/kWh to 60 gCO2/kWh. In Zuidas, Holland, the district cooling installation has reduced carbon dioxide emissions by 75 %.

If district cooling were to expand to take 25% of the cooling market share in Europe, energy consumption would fall by 50-60 TWh resulting in 42-50 million tons less carbon dioxide released into the atmosphere each year.

If Capital Cooling were to reach a 20% market share of district cooling markets of this size in Europe, the US, and China, the technology could deliver emissions reductions up to 36 million tons per year, as much as the sum of annual emissions in Croatia and Estonia.

Capital Cooling has established a project company in the city of Doha, Qatar and is now developing a district cooling project in Doha with a project capacity size of about 500 MW.

Capital Cooling has projects underway in collaboration with major energy corporations in Europe. Their current goal is to be the market leader for deploying district cooling in Europe. They are also interested in entering the US and Chinese markets in collaboration with industrial partners.

In order to affect a substantial expansion in China and India, the company needs long-term partnerships within the energy and finance sector in these nations. The company plans to move beyond the tradition role of consulting firm to also act as an equity investor in district cooling projects.
