Energy Renovation in Melun
In Melun, an energy renovation project may concern a town house just as much as a flat in an apartment block or a home in a more recent development. This diversity means starting from the building as it actually exists: structure, level of insulation, ventilation, heating system and any collective constraints. GRAM Énergie supports you in building a coherent programme of works, whether that means improving the envelope, changing the heating system or reviewing several items at the same time. The aim is to define a logic of intervention suited to the property, rather than adding up solutions without regard to how they interact.
Tip: have your energy performance certificate (DPE) and energy bills to hand for a more accurate estimate.
Why renovate your home in Melun
The town centre brings together older buildings and town houses whose configuration can complicate certain works. Party walls, street-facing façades, small lofts and the vertical arrangement of the homes call for a precise look at the surfaces that are accessible and at the possibilities for insulation. In this type of building, a thermal improvement may involve several complementary items rather than a single intervention. Ventilation also deserves particular attention where window frames have already been replaced.
On the outskirts, the housing developments built in the 1960s and 1970s raise other questions. Rented homes and apartment blocks are numerous, sometimes with communal heating. In this context, not everything is an individual decision: some works may concern the flat alone, while others depend on the building or on the co-ownership. In Melun, a distinction therefore has to be drawn between what can be improved within the home and what requires consideration at the scale of the building.
Surveying the property makes it possible to separate works within the home from interventions that may fall to the building.
Our services in Melun
Global energy renovation
A global energy renovation aims to coordinate several items where a home combines different weaknesses: incomplete insulation, an ageing heating system, inadequate ventilation or hot water production in need of review. This approach makes it possible to build an overall scenario and to check that the chosen solutions remain compatible. It is particularly suited to older properties that have already undergone partial works over the years.
Heat pump
Using a heat pump must be studied in the light of the current heating system, the existing emitters and the thermal performance of the property. In a detached house, the possibilities differ from those of a flat served by communal heating. The study must therefore take account of the status of the equipment and of the technical constraints before this solution is adopted.
Insulation
Works involvinginsulation may concern the roof, the walls, the floors or certain internal partitions depending on the type of building. In an older building or a terraced house, not all surfaces are necessarily accessible in the same way. It is then necessary to determine which areas can be treated effectively without overlooking the effects on ventilation and on the thermal balance of the home.
Thermodynamic water heater
A thermodynamic water heater can be considered where hot water production is individual and the technical layout allows it. The volume available, the position of the appliance and the air intake conditions must be examined before any installation. In a flat, these constraints can be greater than in a house with a plant room or a suitable outbuilding.
Energy audit
Anenergy audit makes it possible to place each item of work within an overall view of the building. It helps to locate heat losses, to understand how the heating works and to compare several combinations of improvements. In an older home, or one already partly renovated, this stage makes it easier to define a more rational order of intervention before undertaking major works.
Mechanical ventilation (VMC)
Mechanical ventilation plays a part in renewing indoor air and must remain consistent with the airtightness of the home. After windows or insulation have been improved, the operation of the ventilation deserves to be checked. In blocks of flats, it is also necessary to identify whether the system depends on the home alone or is connected to a communal installation.
Smart thermostat
A smart thermostat makes it possible to adapt heating settings to periods of occupancy. Its installation nevertheless depends on the existing system and on whether it can be controlled individually. In a home served by communal heating, the scope for control may differ from that of a house with its own heat generator.
Typical projects in Melun
Older town house on several storeys
the loft, the external walls and the ventilation may perform differently. The project must take account of this vertical arrangement and of the space available for equipment.
Flat in a 1960s apartment block
the windows or certain internal linings may fall to the individual home, whereas the communal heating, the roof or the façades may depend on collective decisions. The renovation must therefore be built by separating these scopes clearly.
Rented home in need of upgrading
the owner may need to prioritise between insulation, ventilation and individual equipment. The analysis then serves to identify what can be dealt with directly and what depends on the general operation of the building.
Financial support for your works in Melun
MaPrimeRénov’ (the French state renovation grant), the CEE (energy saving certificates funded by energy suppliers), reduced-rate TVA (French VAT) and the éco-PTZ (an interest-free renovation loan) are among the schemes that may be examined for a renovation project. Whether they can be used depends on the type of works, on the property concerned and on the conditions applying to each application. In an apartment block or a rented property, the framework of the project may also influence how the formalities are organised. To review your situation, you can use the contact form. The French public service France Rénov’ lists the schemes currently in force.
How we work
Identifying the context
we distinguish between a house, a flat, an apartment block, individual heating and a communal installation.
Analysing the items concerned
the envelope, ventilation, heating, hot water and controls are examined according to their role in the property.
Separating the scopes
works within the home are distinguished from those that may fall to the building or to a collective decision.
Building the scenario
the interventions are organised according to their technical coherence and to the constraints of the building.
Carrying out the agreed works
the project is executed within the scope defined beforehand.
We also work throughout the rest of Seine-et-Marne
GRAM Énergie also presents its energy renovation solutions in Pontault-Combault, Savigny-le-Temple and Torcy. For the full picture of our coverage across the department, see the page devoted to energy renovation in Seine-et-Marne.
Frequently asked questions
Which works can be undertaken independently in a flat within an apartment block in Melun?
That depends on the rules of the co-ownership and on the nature of the work. Some internal equipment may fall to the individual home, whereas the façades, the roof, the communal services or certain heating systems require a collective decision. The scope must therefore be checked before the works are defined.
Does communal heating prevent the performance of a flat from being improved?
No. Even where the heating depends on the building, other items can be studied: certain walls, the windows depending on their status, the ventilation or the controls where this is possible. The scope for action depends above all on the configuration of the building and on the communal equipment already in place.
How should a town house with little technical space be dealt with?
The solutions have to be selected according to the volumes genuinely available. The loft, service cupboards, circulation areas or ancillary spaces can determine whether a ventilation system, a cylinder or new heating equipment can be installed. The internal layout must therefore be taken into account from the design stage of the project.
Do works within the home and communal works have to be carried out at the same time?
Not necessarily. They can be planned separately, provided that they are checked for compatibility. Work inside a flat, for example, can anticipate a future project on the façade or on the communal heating. The important thing is to avoid a solution that would later complicate works decided at building level.
Why study the ventilation in an older home that has already been renovated?
Because successive works can significantly alter air exchange. Recent windows or added insulation can make the home more airtight while the ventilation has not changed. Checking how it works makes it possible to confirm that it remains suited to the new configuration of the property.
