The heat recovered from the condensers of the refrigeration units is used to heat domestic hot water. It is a refrigeration cycle that works by drawing heat from the evaporator and discharging it to the outside (condenser). The idea behind the project involves recovering this waste heat to preheat domestic hot water (DHW).
This technology is suitable for food businesses with refrigeration units (cold rooms, refrigerated units, air conditioning, etc.).
By installing this technology, which has been available on the market for more than 5 years, the company can save on its electricity bills and reduce its carbon footprint. However, implementing this measure can be complex with a medium-to-long-term return on investment, and requires the temporary shutdown of production during the technical installation stage
The project involves installing sun control window films on the exterior glazing, which can help reduce the amount of solar heat entering the building. In summer, air conditioning needs and associated energy consumption are reduced. In winter, the need for heating and associated energy consumption may increase slightly.
Sun control window films are suitable for commercial buildings, shop windows and existing businesses with large glazed areas which are likely to overheat inside and have increased air conditioning needs due to solar radiation.
By installing this technology, which has been available on the market for more than 5 years, the company can save on its electricity bills and reduce its carbon footprint, but above all improve comfort. This measure is relatively simple to implement, has a quick return on investment and does not require production shutdown during the technical installation.
There are different types of solar film that can be used to control the solar radiation according to need and season, guaranteeing protection and thermal optimisation in both winter and summer, without any loss of luminosity.
Adjustment of air exchange flow rates to actual needs using a CO2 sensor
The project aims to install one or more CO2 sensors on the air intake of air handling units (AHUs) in supermarkets and to adjust the flow rate of new air introduced into the shopping centre as needed. This way, the airflow is increased during busy periods and reduced the rest of the time.
Air handling units ensure the air exchange and heating/cooling of the commercial premises. The AHUs operate at a fixed flow rate over time slots programmed according to opening hours.
By installing this technology, which has been available on the market for more than 5 years, the company can achieve significant savings on its electricity bills and reduce its carbon footprint. This measure is relatively simple to implement, has a quick return on investment and does not require production shutdown during the technical installation.
Replacement of linear or vertical chillers and freezers
The project aims to replace old chillers and freezers with new generation refrigeration units that are closed, well insulated, fitted with more efficient fans and LED lighting. Defrosting is optimised and it is possible to increase the temperature regime of the evaporator circuit.
This system applies to supermarkets or grocery stores with chillers and freezers to store food in store. By installing this technology, which has been available on the market for more than 5 years, the company can save on its electricity bills and reduce its carbon footprint. However, implementing this measure can be complex and requires the temporary shutdown of production during the technical installation stage.
Installation of a transcritical CO2 refrigeration system
The project involves replacing an existing conventional, centralised, or direct expansion installation with a refrigeration system using CO2 as a fluid which is transferred in a transcritical or subcritical cycle (cascade or refrigerant) to the units diffusing the cold (refrigerated units, cold room evaporators, etc.) for a positive or negative application, or both.
This system applies to existing commercial buildings, particularly food distribution premises. This includes spaces intended for the display or self-service of fresh products for the public, such as hypermarkets, supermarkets, and small food stores. Drive-through facilities and click and collect points allowing the public to pick up their purchases without actually entering the store (the “drive-through” concept) as well as refrigerated warehouses.
Setting up this new technology will allow the company to save electricity, while reducing its carbon footprint. However, implementing this measure can be complex and requires the temporary shutdown of production during the technical installation stage.
Electric mobility, a key element in decarbonising your business
Electric cars are part of the solution to successfully decarbonising your company’s vehicle fleet. It is also essential to set up a suitable charging infrastructure within the company so that the logistics of charging can be managed internally. For greater autonomy, the system can be combined with a solar power installation.
Energy savings: lighting, a key element in energy consumption in the workplace
Lighting accounts for around 10% of electricity consumption in buildings. The potential savings are quite varied and depend heavily on the condition and management of the lighting system. In order to unlock the full potential, this measure proposes a range of optimisation measures, from simple practical initiatives to a complete overhaul of the lighting system.
Photovoltaics: an environmentally and financially interesting alternative for your company’s electricity production
A photovoltaic installation enables you to produce renewable electricity and to decouple part of your electricity costs from market price fluctuations. Beyond self-consumption, there are other support mechanisms that can represent an interesting economic model, such as the guaranteed feed-in tariff or the market premium resulting from a call for tenders. The installation can be financed from your own funds or by a third-party investor, who can also take care of its planning and completion.
Promoting self-consumption and electricity sharing within your company
Self-consumption refers to using the electricity that you generate on your own. This approach helps you become less reliant on the energy market and suppliers, insulating you from price fluctuations. For instance, by installing solar panels, you can produce renewable electricity that meets your company’s electrical needs, whether it’s for lighting, powering an EV-charging station, or running other appliances. Additionally, this self-produced energy can also be used to power larger systems like heat pumps.
The following article provides an overview of various self-consumption methods, highlighting their benefits and drawbacks, along with the necessary procedures, available subsidies, and relevant measures.
In order to have an overview of a company’s energy situation, it is important to monitor its consumption. Carrying out an energy analysis enables you to detect over-consumption and determine the measures you need to take to improve. With a view to continuous improvement, regular monitoring is essential.
