Craft IndustryTo make this measure more effective and tailored to the specific context of your company, we recommend that you first perform an overall analysis of your energy situation.
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.
Adjusting the supply of fresh air according to occupancy has the effect of:
The use of CO2 sensors with dampers and controls to adjust the flow of fresh air introduced will have a positive effect on the overall energy costs associated with air handling units. It helps reduce electricity and fossil fuel consumption if the hot water supplied to the heating coils is produced by a boiler.
Please note: any application for government or non-government subsidies must comply with the “incentive effect”, subject to compliance with the subsidy conditions.
To ensure that the ‘incentive effect’ is respected, no binding commitment (signing a quotation; paying an advance) may be made BEFORE submitting the application file or receiving the agreement in principle from the State or the electricity and natural gas supplier following an application for subsidies.
Since 2015, natural gas and electricity suppliers are required to make energy savings for consumers under the obligation scheme. Since then, energy suppliers have been offering support and advice, as well as subsidy programmes for consumers to implement energy efficiency measures.
The following suppliers offer this service for companies:
N.B. Supplier subsidies can be combined with any state subsidies for the same project.Energy savings are estimated at 30% for the air handling unit consumption and 5 to 10% for overall energy consumption. This measure also contributes to a reduction of a few percentage points in the carbon footprint.
The tax relief is calculated based on the investments and operating expenses incurred as part of an ecological and energy transition project.
The tax relief rate is set at 18% and is applied directly to the amount of tax due.
This deduction can be combined with standard state subsidies.
For the project to be eligible, it must meet at least one of the following objectives:
For certain objectives, minimum thresholds must be met.
To verify your eligibility and ensure that these thresholds are satisfied, it is recommended that the impact of the measure on one of the above conditions be certified by an expert or a design office.
