Why carry out a whole-building renovation with Gram Energie?
The energy renovation of a building goes far beyond a simple cosmetic update. It is a crucial step in meeting environmental and economic challenges and the comfort needs of residents. Here is why:
Energy efficiency
Energy renovation considerably reduces a building’s energy consumption by improving its insulation, modernising its heating and ventilation systems and integrating eco-friendly solutions such as heat pumps and solar systems. By reducing dependence on non-renewable energy, we actively help to tackle climate change.
Financial savings
A well-planned energy renovation can deliver substantial long-term savings on energy bills. By improving the building’s energy efficiency, owners and occupants benefit from lower heating and cooling costs, which translates into significant financial savings.
Increasing property value
By investing in an energy renovation, owners increase the value of their property. A renovated, energy-efficient building is more attractive on the rental or resale market, which can raise its intrinsic value.
How does a project work?
A tailored project in 5 steps
1. Eligibility assessment
We assess the feasibility of your project and check that it fits our services. We then put together the administrative and technical file needed to move forward.
2. Initial audit:
Every project starts with an in-depth audit. We carry out an on-site assessment, identify specific needs and determine the necessary work, taking all requirements into account.
3. Start of works:
Once the quote is approved, the work begins. Our specialist teams make sure the project is carried out properly, using materials that comply with current standards.
4. Handover:
Once the work is complete, a quality check is carried out by an approved body. This step ensures the project meets the required quality standards.
5. Validation and CEE claim:
Once the project is finished, you sign a declaration confirming the work carried out. This allows us to claim the Energy Savings Certificates (CEE), so you benefit from additional advantages.
