Energy Renovation in Nancy
In Nancy, energy renovation must adapt to a very varied built heritage: older buildings, Lorraine townhouses, Art Nouveau villas, co-owned buildings and detached houses across the Métropole du Grand Nancy. In Meurthe-et-Moselle (54), cold winters increase the importance of good insulation and a heating system that is consistent with the property’s requirements. GRAM Énergie supports you in building a project suited to the building, its architecture and existing equipment. Works may concern the walls, loft, windows, ventilation or an old boiler, with an approach aimed at improving comfort and energy management without applying the same solutions to every building.
Tip: have your energy performance certificate (DPE) and energy bills to hand for a more accurate estimate.
Why renovate your home in Nancy
Around place Stanislas and in the Vieille-Ville, 18th-century heritage requires particular attention to façades, windows and doors, and the external appearance of buildings. An energy renovation therefore cannot always rely on external insulation or standardised window replacement. Depending on the building’s situation, solutions must respect the existing architecture and the applicable heritage constraints. The project may then favour certain internal treatments, work on the loft or improvements to equipment, while preserving the visual coherence of the property.
Nancy also has an important Art Nouveau heritage, associated in particular with the École de Nancy. In the buildings and villas concerned, windows and doors, internal volumes and certain decorative elements may influence the choice of works. A renovation must therefore take account of both the performance being sought and the character of the building. In this context, insulation, heating and ventilation must be assessed according to the actual construction rather than by following a uniform solution.
Older stone co-owned buildings represent another common type of housing in Nancy. Some works relate to the private property, while the façade, roof or a boiler room may depend on the co-ownership. Owners must therefore distinguish individual decisions from collective interventions. In the more residential areas of the Métropole du Grand Nancy, townhouses and detached homes may have other priorities: poorly insulated lofts, single glazing, an ageing gas boiler or limited controls. Alohé, the housing and energy centre of the Métropole du Grand Nancy, together with ALEC and Oktave, are among the services and schemes that can provide private individuals with information about their renovation pathway.
The audit makes it possible to prioritise interventions according to the condition of the building, its architecture and its energy requirements.
Our services in Nancy
Global energy renovation
A global energy renovation makes it possible to organise several works within the same project: insulation, heating, ventilation, hot water and controls. In Nancy, this approach can be useful when a house or flat has several weaknesses. It helps build a coherent plan, distribute the interventions and avoid a decision made about one piece of equipment making later work on the building envelope more difficult.
Heat pump
A heat pump can be considered to upgrade an older heating system. Its suitability depends on the level of insulation, heat emitters, thermal requirements and the space available. In a house within the Métropole du Grand Nancy, it is preferable to assess heat losses before selecting the equipment in order to maintain consistency between output, comfort and energy consumption.
Insulation
Insulation works may target the walls, loft, roof or certain floors. In an older stone building or a property with architectural interest, the solution must be adapted to the substrate and the constraints of the location. Internal insulation can sometimes be considered where the façade must be preserved, but its installation must remain compatible with moisture and the behaviour of the building.
Thermodynamic water heater
A thermodynamic water heater can be considered for domestic hot water production. Its installation depends on the available volume, connections and the characteristics of the property. In a house as well as in a flat, it must be incorporated into the overall project in order to maintain practical use and good consistency with the other equipment.
Energy audit
An energy audit helps analyse heat losses, equipment and usage before defining the works. It makes it possible to compare several scenarios and better understand which areas should be treated first. For owners hesitating between insulation, replacing the heating system or improving the windows, this assessment provides a structured basis for moving forward.
Mechanical ventilation
Ventilation must be examined when windows and doors become more airtight or insulation is improved. In an older property, air renewal may have been altered over time by successive changes. Suitable mechanical ventilation helps maintain coherent airflow and limit moisture accumulation in certain rooms, without separating this issue from the rest of the interventions.
Smart thermostat
A smart thermostat makes it possible to control heating more precisely according to schedules and occupancy habits. It can complement a recent or existing installation, but does not replace necessary work on a poorly performing building envelope. Its usefulness depends on the system in place and the level of renovation already achieved in the property.
Typical projects in Nancy
Older flat in a heritage area
The façade and windows and doors may be subject to particular constraints. The project must therefore seek solutions that improve indoor comfort without altering the external architecture. The loft, internal walls, equipment and controls may be among the areas considered depending on the property.
Flat in a stone co-owned building
Some works are private, while the roof, façade or certain communal equipment depend on the building as a whole. Owners must therefore identify what can be undertaken individually and what requires a co-ownership decision. This distinction makes it easier to prepare grants and organise the interventions.
Lorraine house or detached home with single glazing and an old boiler
This type of property may combine several sources of heat loss. Before replacing the heating system, it is useful to examine the windows, loft and walls in order to estimate future requirements. This approach helps avoid oversized equipment after improvements to the building envelope.
Grants for your works in Nancy
Several grants can be considered as part of an energy renovation: MaPrimeRénov’, the CEE (energy savings certificates) scheme, reduced VAT and the éco-PTZ (zero-interest eco-loan). Anah is also involved in various housing-related pathways. Certain grants require the use of an RGE-certified professional. For households on modest incomes as well as other profiles, amounts, bonuses and conditions depend on the situation, property and nature of the works; they must therefore be checked before any commitment is made.
Alohé, the housing and energy centre of the Métropole du Grand Nancy, is a public information service for private individuals. ALEC can also provide advice on energy, while Oktave operates across the Grand Est region. These services can complement project support and help explain the available grants. To present your situation to GRAM Énergie, use the contact page. You can also consult France Rénov’ to check MaPrimeRénov’, the CEE scheme and the other applicable schemes.
MaPrimeRénov’, the CEE scheme and other schemes must be considered according to the applicant’s profile and the content of the works.
How we work
Understanding your situation
We identify the type of property, equipment, consumption, works already carried out and any constraints relating to the building.
Analysis of priorities
The walls, loft, windows, ventilation and heating are examined to identify the main sources of heat loss.
Building the project
Solutions are compared according to the architecture, the type of house or flat and the performance objectives being pursued.
Organisation of the works
The interventions are ordered in order to maintain consistency between insulation, equipment and co-ownership or heritage constraints.
Support through the stages
Monitoring maintains consistency between the initial assessment, grants examined, decisions made and the planned implementation.
We also work across Grand Est
GRAM Énergie also supports renovation projects in Metz, Strasbourg and Reims. To view the other areas of the département, go to the page dedicated to energy renovation in Meurthe-et-Moselle. The page dedicated to energy renovation in Grand Est provides access to the other areas of the region.
Frequently asked questions
How can a flat near place Stanislas be renovated without altering its façade?
Solutions can focus on the interior, loft, equipment or certain windows and doors that are compatible with the constraints of the building. The choice depends on the architecture and applicable rules. A preliminary assessment makes it possible to distinguish what can be altered freely from what requires particular heritage consideration.
Do Nancy’s Art Nouveau villas require a particular approach?
Yes, because certain architectural elements may form part of the character of the building. Windows, decorative features and internal volumes must be taken into account when choosing insulation and equipment. The aim is to improve energy performance without diminishing the architecture or applying a standard solution to a distinctive property.
How should works be divided between a flat and its co-ownership?
The first step is to identify private and common elements. An individual boiler, certain internal equipment or controls may belong to the flat, while the façade, roof or a communal boiler room depend on the co-ownership. This division then makes decisions, grants and scheduling of interventions easier.
Do households on modest incomes have access to the same grants as other owners?
Pathways and conditions may vary according to the household’s situation, the property and the selected works. MaPrimeRénov’, Anah and other schemes have specific rules depending on the circumstances. Amounts and bonuses must therefore be checked when preparing the application, without assuming that a particular grant will apply.
What information should you provide to assess an energy renovation in Nancy?
Gather energy bills, available surveys, information about the heating system, any plans and, in a co-owned building, useful documents relating to the property. For an older building, information linked to its architecture may also be important. To send your request to GRAM Énergie, use the contact page.
