Energy efficient supermarkets - Checklists and Educational material
Here we collect checklists and educational materials.
Small-scale biogas plant at large grocery stores
The possibility of establishing a small-scale biogas plant at larger grocery stores to handle the food waste that arises in stores has been investigated. If technical, economic, and environmental aspects are considered, the assessment is that it is better to transport the grocery store’s food waste to a digestion plant nearby.
LED conversion of refrigerated counters
This is a guide how to make a safe and correct LED conversion of the refrigerated counter regarding electrical safety and EMC and still be able to claim compatibility with LVD and EMC-directive. Laws and directives referred to in the report may have been updated and may not be applicable.
Cleaning of heat exchangers in display cabinets
Dirt and dust are drawn into cooling batteries during operation and sometimes food packages break so that the content drips down into the counter. Contamination can cause decreased efficiency in the counter’s cooling coil, reduced air flow and clogging of drains, which can lead to an increased energy demand for cooling the air in the counter and to ruined food due to inadequate cooling. A checklist for washing cooling batteries has been produced.
Energy efficient ventilation in stores – recirculated air
Measurements has been performed in order to verify the energy saving potential for comfort heating and comfort cooling when using recirculated air, compared to ventilation with outdoor air, while a good indoor environment is achieved regarding, among other things, air quality. The results from the measurements showed a large saving potential by using recirculated air, while good air quality was achieved both with and without recirculated air.

Are you in the market to order or change your ventilation? Here is a good manual to help.
Ten tips for action
Here you get suggestions for ten areas of action that will help you and your co-workers get started quickly with the energy work. Divide the work into teams and appoint those responsible for different areas. The measures are simple, save energy and are inexpensive to implement.
The energy-wise grocery store
Checklist for the store's own energy work.
Design of cooling systems for stores based on the best available technology
The purpose of this pre-study is to investigate three different system solutions for food refrigeration and how they should best be designed to achive the highest possible energy efficiency with a focus on the technical potential. The results show that dimensioning of components, and the possibilities for regulation in a large work area, have a greater effect on energy performance than the choice between the three optimized cooling systems examinated. It's important to dimension the components optimally for the operating conditions that are most common, in terms of hours per year.
Priority actions in existing food premises for increased energy efficiency
The aim of the feasibility study has been to produce a prioritized compilation of the most important measures for energy efficiency in food premises. The results show that energy efficiency does not have to be expensive - much can be done quickly and at a low cost. Usually no major investment is required in components or equipment.
