The energy transition is more than ever one of the main concerns of government authorities. It obviously involves households, but also installers and businesses. In the context of energy renovation, the State has introduced various types of aid to finance part of the work and thus encourage residents to optimise their energy consumption. In the building sector, this has created a new business that will only grow over time.

Energy renovation passport: a real booster

Although many homeowners are considering energy retrofits, they do not always have sufficient information to get started. That is why the energy renovation passport was created in 2015. Individuals receive free support from suppliers in the context of their project. Professionals will carry out a thermal assessment of the dwelling and recommend work according to the needs of households. For RGE-certified installers (recognised environmental guarantor), this is a real opportunity to boost their business. They are the only ones authorised to provide this type of service and can offer owners a partial or global renovation offer.

Increasingly sought-after professionals

The work required as part of the energy renovation is primarily concerned with insulation through windows and vertical walls. Then there is the optimisation of heating and hot water installations. The more efficient the renovation is, the higher the budget. For contractors, this is a real boost to their business. According to some dealers, the sale of equipment and materials as part of the energy transition can boost sales by up to 80% (for the wholesale trade).

Potential for various R&D approaches

In R&D, much of the work is aimed at finding better solutions to energy efficiency needs. There are various types of techniques to be addressed, including insulation processes, prioritizing cost-effectiveness, lightness and strength. Exploration also extends to the industrialization of renovation techniques, through the design and experimentation of technological packages (association between thermal systems and insulation of the building envelope). Finally, the researchers recognize the interest in finding numerical methods to facilitate diagnostics on existing buildings. The aim is to make the choice of energy renovation techniques more reliable and ensure better performance. As a result of this global approach to energy performance, the business in this field is not about to stop flourishing.
