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 the decarbonisation of your company
In order to achieve carbon neutrality by 2050, replacing internal combustion vehicles with electric vehicles is crucial. Greenhouse gas (GHG) emissions linked to the transport of people and goods keep rising within the European Union. This concerns all types of vehicles, and a transition is necessary to meet national and European targets.
Purchasing these vehicles in principle requires the installation of one or more electric charging station(s) and can be supplemented by the installation of photovoltaic panels.
Key steps and aspects to consider when planning and implementing this change are outlined below.
In order to achieve carbon neutrality by 2050, minimising the use of the vehicle fleet and promoting soft mobility alternatives is crucial. This measure aims to reduce the company’s carbon footprint by reorganising the company’s general mobility.
Considering the country’s special situation in that public transport is free, employees should make more use of it by changing their consumption habits.
Individual behaviour has a major influence on resource consumption. To make employees aware of the impact of their actions, an awareness campaign is ideal.
The details below provide guidelines for setting up a staff awareness campaign, to ensure responsibility and lasting commitment to the themes of energy, resources, and climate within the organisation.
How to reduce electricity costs through intelligent use of IT equipment
The growing use of IT equipment inevitably leads to an increase in energy consumption, whether due to the execution of software applications, communications via LAN/Wi-Fi networks, etc.
The link between IT equipment and energy consumption is not directly visible, as electricity consumption is not dissociated from the other electrical installations available within the company.
Carrying out a sustainable IT diagnostic enables company managers and employees to optimise their digital environmental footprint and consumption.
Company halls and workshops, often characterised by large open spaces and high ceilings, present a particular challenge when it comes to installing an energy-efficient, targeted heating system. The ideal heating system for halls must therefore be able to heat the different work areas individually and produce heat at the right height.
Halls and workshops have specific heating requirements due to their size and use. It is therefore essential to carry out a thorough requirements analysis before installing a new heating system.
