Cooperation between Supermarkets and Real Estate Owners; Energy Efficiency and Business Models

The overall aim of the project is to demonstrate, using theoretical calculations, modelling, energy measurements, monitoring and business model evaluation, that a collaboration for efficient use of heating, cooling and air conditioning between real estate and supermarkets owners can be achievable for both parties.

Grosery stores and real estate owners

Background

Today there are about 4000 Supermarkets in Sweden, and those account for about 3% of Swedish electricity use. Supermarkets have the potential to reduce energy use through delivering heating and air conditioning to stores and neighbouring buildings.

During the project, at least four case studies will be investigated with focus on cooling, heat recovery and air conditioning. The results from the project will lead to the implementation of at least two cases of collaboration between supermarkets and real estate owners. The energy and business models that will be developed during the project will be freely available for the different stakeholders in the project.
