Replacement and centralisation of cold production units with a variable speed compressor
The project consists in fitting cold rooms and/or freezers in the butcher shop with cold air curtains to prevent warm air flows from entering cold rooms and freezers when their doors are opened.
By installing this technology, which has been available on the market for over 5 years, the company can save on its electricity bills by an estimated 10%. This measure is rather easy to implement and would entail a medium-to-long-term return on investment. Implementing this measure does not require production shutdown during the technical installation stage.
Smart climate control is performed on a large set of building data over long periods to identify malfunctions and savings opportunities, while enabling the user to assess the effectiveness of corrective measures that are taken.
This technology is suitable for hotels with manually controlled technical equipment such as heating, ventilation, and air conditioning.
Setting up this new technology will allow the company to save energy, while slightly reducing its carbon footprint. This measure is simple to implement with a medium-to-long-term return on investment and it does not require shutdown of production during the technical installation stage.
Building management system (BMS) is an interface which remotely controls electronic and mechanical systems in one or more buildings. In particular, BMS takes care of the remote control of the hotel’s heating, ventilation and air conditioning systems, which consume a lot of power.
This technology is suitable for existing hotels wishing to retrofit a BMS system, as well as new buildings where BMS is implemented from the design stage.
The company will be able to make substantial energy savings and reduce its carbon footprint by installing this technology, which has been on the market for over 5 years. This measure is quite simple to implement, even if there is a medium-to-long-term return on investment and it requires a partial shutdown of production during the technical installation stage.
Decentralisation of domestic hot water production with or without thermodynamic water cylinder
The project consists in separating the hot water production system from the heating system. This can be done in two ways:
through partial decentralisation in summer, by adding a small boiler to heat the domestic hot water. It will allow to shut down the main boiler in summer but will still be connected to the hot water system. Decentralisation can also not be total if the domestic hot water production system is separate, either following the installation of a thermodynamic water cylinder operating at high temperature (advantage of the COP on electricity consumption linked to the production of DHW compared to an electric boiler)
through the installation of a boiler sized to cover the DHW requirement, or the installation of suitable electric boilers with storage capacity to limit power demand peaks.
This technology is particularly suitable for hotels with a high demand for domestic hot water. Setting up this new technology will allow the company to save energy, while reducing its carbon footprint. However, implementing this measure can be rather complex with a medium-to-long-term return on investment, and requires the temporary shutdown of production during the technical installation stage.
Heat recovery via heat pump on grey water or cooling circuit
The project consists in recovering the heat lost in the grey water system (showers, sinks, washing machines, dishwashers, etc.) of a hotel or restaurant by reusing it to heat domestic hot water (large consumption in such facilities). The process involves the recovery of heat via a water-to-water heat pump from a cold source at high temperature throughout the year.
This technology is particularly suitable for hotels with a high demand for domestic hot water.
By installing this technology, which has been available on the market for more than 5 years, the company can save on its energy bills and reduce its carbon footprint. However, implementing this measure can be rather 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.
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.
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.
The heating installation: an important leverage point in the energy transition
The heat production unit is a major leverage point for a successful energy transition. As its primary purpose is to supply heat for comfort and operational needs, the heating system must be scaled to provide the temperature levels and necessary quantities to keep the business running. Nowadays, there are heat production systems that are adapted to each temperature level are flexible in terms of power and are environmentally friendly.
