Global Data Technology, POWER Technology
Modern district energy systems are the most effective approach for many cities to transition to sustainable heating and cooling. This is achieved by improving energy efficiency and enabling higher shares of renewables. Modern district energy systems are designed to connect renewables, waste heat, thermal storage, power grids, thermal grids and heat pumps. As a result they can use up to 50% less primary energy consumption for heating and cooling.
These benefits make district energy a key measure for cities/countries that aim to achieve 100% renewable energy or carbon neutral targets. So when compared with competitive technologies, district energy is frequently more cost effective – by up to 50% – than individual buildings producing their own heating or cooling.
Improvements in efficiency drive UN initiative
The District Energy in Cities Initiative is a multi-stakeholder partnership coordinated by UN Environment, with financial support from Danish International Development Agency (DANIDA), the Global Environment Facility, and the Government of Italy. It is one of six accelerators of the Sustainable Energy of All (SEforAll) Energy Efficiency Accelerator Platform launched at the Climate Summit in September 2014. The Initiative supports market transformation efforts to shift the heating and cooling sector to energy efficient and renewable solutions. By doing this it aims to double the rate of energy efficiency improvements for heating and cooling in buildings by 2030, helping countries meet their climate and sustainable development targets.
