Initial energy analysis
study of the building’s condition and consumption.
To achieve carbon neutrality by 2050, Europe must fundamentally transform its existing building stock. At Retrofitt, we believe that deep energy renovation combined with off-site construction is the fastest, most sustainable, and most effective way to reach this goal.
The challenge: renovating 6,000 homes per day
The building sector accounts for about 40% of energy consumption in Europe. To meet its climate commitments, the European Union must massively accelerate the pace of renovations. Traditional solutions are no longer enough: we must aim for 6,000 energy renovations per day.
This is where off-site renovation comes in.
Deep energy renovation vs. superficial renovation: what’s the difference?
What is deep energy renovation?
Deep energy renovation (or deep retrofit) means completely rethinking the building to make it high-performing, healthy, and sustainable.
It enables energy consumption reductions of 30 to 70% thanks to a holistic approach:
-
Full thermal insulation : walls, roof, floor, windows, and doors.
-
Enhanced airtightness.
-
Ventilation systems with heat recovery.
-
Integration of renewable energies (solar panels, heat pumps, etc.).
The building is treated as a coherent system, where all elements interact to ensure optimal performance.
And what about superficial energy renovation?
This involves isolated actions such as:
- Insulating pipes or the attic,
- Adding insulation around the boiler,
- Installing a smart thermostat,
- Replacing a boiler with a more efficient model.
While these measures may seem effective short-term, they don’t deliver a global performance leap nor prepare for 2050 climate requirements. Worse, they might need to be redone in a future renovation. A true energy strategy starts with a comprehensive vision.
The Retrofitt method : 7 steps for deep energy renovation
At Retrofitt, we have designed an industrial, efficient, and repeatable method to accelerate building energy renovation:

23D point cloud scanningcomplete digital scanning to create an accurate digital twin.
-
3Architectural redesigndevelopment of new façades and roofs according to energy goals.
-
4BIM modelingcreation of a digital twin including all components.
-
5Off-site productionfactory manufacturing of elements (panels, insulation, finishes).
-
6Optimized logisticssecure transport of components under controlled quality conditions.
-
7Rapid on-site installationassembly by our trained teams with minimal disruption.
Deep energy renovation: a winning solution for all
- For occupants: more thermal comfort, healthier air, lower bills.
- For communities: an effective response to energy poverty.
- For the planet: more efficient, durable buildings with controlled environmental impact.
Partner for carbon-neutral buildings
Carbon neutrality by 2050 is not a dream but an achievable goal if we scale up. At Retrofitt, we put innovation, industrialization, and energy performance at the heart of a sustainable and rapid renovation, matching the climate challenges.
