4- Demonstration of optimised energy systems for high performance-energy districts.


The READY project aimed to demonstrate how the demand for energy and particularly the needs for fossil fuels and release of CO2 can be considerably reduced to nearly zero, and show a sustainable way to go for other European cities.

The demonstration took place in two cities: Aarhus (Denmark), which is representative of the north western parts of Europe and Växjö (Sweden) - representative of the Baltic Sea region. Both cities have a depth of technical experience and have been frontrunners for years in setting and carrying out ambitious climate and smart city policies. Kaunas, in Lithuania, took part as an observer city in order to bring in Eastern European experience with a most relevant context.

Based on thoroughly integrated climate planning the READY project demonstrated a Whole City Approach including:

  • Demo of a balanced and holistic approach towards affordable retrofitting of residential buildings and offices;
  • Development and demo of new solutions for low-temperature district heating, components and management ICT systems;
  • Development and demo of flexible combined grid balancing/energy storage solutions for buildings and RES systems including combined heat pumps for heating and cooling, electrical vehicles charging, new PVT systems and second-life reuse of EV batteries in buildings;
  • Resource and energy smart solutions for kitchens;
  • Solutions for water efficiency and waste water energy recovery;
  • Demo of new innovative industrial equipment for use of RES and integration of demand and supply, – based on business plans, and follow-up by promotion and dissemination activities.
