To 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.
Installation of sun control window films
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.
Energy and environmental impact
Installing solar films offers a number of advantages:
- Significant reduction in solar gain in summer
- Better insulation in winter
- No loss of light
- Reduced glare
- UV protection for furniture and decorative objects
- Can be installed indoors or outdoors, with no impact on activity
Energy savings are estimated at between 10 and 20% for cooling consumption, which also contributes to a slight reduction in carbon footprint.
State subsidy application
Aides étatiques
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.
Temporary environmental impact aid
Extended “SME Packages Sustainability” aid scheme, to give companies greater incentives to invest in measures that significantly improve their environmental impact. Investments under this climate protection measure amount to 70% for small enterprises, 60% for medium-sized enterprises and 50% for large enterprises, for projects costing more than €7,500, with a maximum subsidy of €100,000.

Subsidies from electricity and natural gas suppliers
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:
