Residual energy use and energy efficiency improvement of European supermarket facilities during the post-COVID and energy crisis period.

Supermarkets are significant consumers of electricity and contribute to the generation of associated pollutant emissions. This will help to mitigate the impact of increased energy costs on the prices of products sold in supermarkets. Therefore, it is essential to reduce energy consumption, starting with the equipment that consumes the most electricity, such as refrigeration, and using the residual thermal energy generated in supermarkets.

The development of modern cities favours the formation of metropolitan zones with urban and industrial areas. The central metropolitan area (CMA) of the Principality of Asturias (northwest Spain), takes up 9.6% of the territory and represents 78% of its population.
