Executive Summary The SUPER-HEERO project aims at providing a replicable financial scheme for energy efficiency investment in small and medium supermarkets, based on stakeholder and community engagement. Note that by supermarkets we refer to self-service shops offering a wide variety of food, beverages and household products: they are larger and have a wider selection of products than grocery stores but are smaller and more limited in the range of merchandise than a hypermarket or big-box market. The present D2.1 of the SUPER-HEERO Project, building upon a high-level analysis of typical supermarkets’ energy systems and equipment, creates a catalogue with the most relevant and easy to replicate energy efficiency measures to be promoted by SUPER-HEERO renovation approach. Based on this catalogue of solutions, guidelines will be provided to promote the implementation of energy efficiency measures in supermarkets according to their size, estimated sales volume, staff amount, kind of products, etc., covering both technical and financial aspects. These guidelines will be included in SUPER-HEERO D2.2, available in Spring 2021. In the present Deliverable, to define the catalogue of the most suitable energy efficiency actions for supermarkets, a high-level energy analysis of a typical supermarkets is needed and is carried out according to the following main steps: ● identification of supermarkets’ typical energy balance; ● definition of typical energy consumption level (electricity/heat); ● analysis of typical breakdown of energy consumption; ● selection of key areas for energy efficiency improvement; ● elaboration of energy efficiency measures’ catalogue. Based on the analysis of typical supermarkets’ energy balances, the key areas for energy efficiency are identified as the following six: ● overall energy management; ● energy supply; ● heating, ventilation, air conditioning; ● lighting; ● product refrigeration; ● other areas. A number of 42 energy efficiency interventions are presented that belong to the above-mentioned six areas. It can be noticed that the last four areas are directly correlated with the categories of energy users that are identified as responsible for the largest part of energy consumptions in the previous section, whereas the first two are more general and may lead
