Interview with Hélène André, marketing manager at Kelvin

While energy renovation needs to accelerate on a large scale, professionals in the sector still face major obstacles in qualifying, analyzing, and implementing their projects. To address this, Kelvin offers an innovative platform capable of automatically modeling a home in 3D from a simple address, thus facilitating the understanding, planning, and sale of renovations.

Batinfo: Who is your solution aimed at and what problem does it address?

Hélène André: Today, the energy transition relies on the renovation of millions of homes, but for energy renovation professionals—tradespeople, installers, sales engineers, and engineering firms—projects remain difficult to sell. Homes are complex to understand remotely, assessments are time-consuming, and homeowners often struggle to visualize the project and therefore decide to undertake the work. As a result, many opportunities are difficult to qualify and even harder to finalize, despite the millions of homes in need of renovation.

Batinfo: How do you address this issue and what makes your solution innovative?

Hélène André: At Kelvin, we've developed the energy renovation sales platform. It allows professionals to identify more opportunities, quickly analyze projects, and more easily convince homeowners. Our innovative approach is based on a 3D model that is automatically generated from a simple building survey anywhere in France. In just a few seconds, the sales engineer can understand the property, including its dimensions, surface areas, and wall orientation. They can then work on a renovation plan wall by wall to create credible, informative, and clearly costed renovation proposals that reflect the realities on the ground. This 3D visualization becomes a powerful sales tool, enabling homeowners to understand the project and envision the renovations.

Batinfo: How can your solution be implemented?

Hélène André: In practical terms, implementation is very simple, since ultimately, all you need is an address to automatically generate a 3D model of the dwelling, without requiring any special technical skills or equipment, whether it's LiDAR or a state-of-the-art smartphone. Teams can then qualify the project, work on renovation scenarios, and share it with the project ecosystem. This means sharing the 3D model with engineering firms, other construction companies, or uploading it to thermal calculation software. Today, more than 200 renovation companies use Kelvin with its 3D modeling capabilities, and there are over 1.500 users who, in 2025 alone, analyzed more than 130.000 homes and estimated renovation costs using Kelvin. Ultimately, our goal remains the same: to help professionals grow their business and accelerate energy renovation in France.
