Energy Renovation in Savigny-le-Temple
In Savigny-le-Temple, energy renovation concerns a housing stock largely shaped by the development of the new town: terraced houses, town houses and blocks of flats built mainly in the 1980s. These homes often have compact volumes, party walls and heating equipment that is now ageing. GRAM Énergie supports you in determining which items genuinely deserve to be improved and in what order to address them. The aim is to adapt the project to the configuration of the property, whether that means reducing heating requirements, replacing old electric heaters, upgrading a gas boiler or reviewing the ventilation.
Tip: have your energy performance certificate (DPE) and energy bills to hand for a more accurate estimate.
Why renovate your home in Savigny-le-Temple
Terraced and semi-detached houses have an interesting feature: some of their walls adjoin other homes rather than giving directly onto the outside. These party surfaces limit certain heat losses, which can change the priorities compared with a house standing alone on its plot. It then becomes particularly useful to examine the roof, the façades that are genuinely exposed, the floors and the openings. External wall insulation may also be more complex to consider where the façades form part of a uniform architectural whole or where the boundaries between homes are narrow.
Another feature of the area: some homes from the 1980s still have first-generation electric heating or gas boilers installed long ago. In a compact house, replacing the heating must take account of the small amount of space available for new equipment and of the layout of the rooms. In Savigny-le-Temple, the project therefore benefits from being thought through around the actual performance of each wall and the space available, rather than from a standard scheme applied to every house.
A thermal study helps to identify the walls that are genuinely exposed and the equipment to prioritise in a compact home.
Our services in Savigny-le-Temple
Global energy renovation
A global energy renovation makes it possible to study the envelope of the property and its equipment at the same time. In a terraced house, the priorities can differ from those of a detached house: the roof, the front façade, the rear façade, the ventilation and the heating then take on particular importance. The approach serves to organise the works according to how they interact and to avoid successive interventions that contradict one another.
Heat pump
Choosing a heat pump depends on the requirements of the property once its insulation has been taken into account. In a town house, the possible position of the outdoor unit, the proximity of neighbouring homes and compatibility with the existing emitters must also be studied. The installation must therefore be assessed on the basis of the precise configuration of the property, and not solely on the heating system it would replace.
Insulation
Addinginsulation must target the surfaces that genuinely separate the inside from the outside or from unheated spaces. In a terraced home, not all walls have the same thermal role. Work can therefore concentrate on the roof, on certain façades or on a floor rather than on all the walls. This reading makes it possible to adapt the works better to the constraints specific to grouped housing.
Thermodynamic water heater
The thermodynamic water heater can replace an old hot water production system where its siting suits the property. In a compact house, the question of space is important: the utility room, the garage or another service space must be studied precisely. The way the equipment works must also remain compatible with the ventilation and with the use of the adjoining rooms.
Energy audit
An energy audit makes it possible to distinguish a property’s real weaknesses from those assumed on the basis of its year of construction. Two houses in the same development may have evolved differently over time. The audit examines the walls, the equipment and the patterns of use in order to build several scenarios of works and to direct investment towards the most relevant items.
Mechanical ventilation (VMC)
Mechanical ventilation plays an essential role in compact homes where the kitchen, bathroom and bedrooms are close together. Renovating the envelope or the windows can alter the original air movement. It is therefore useful to check the existing system, the air inlets and the possibilities for routing ducts, so that appropriate air renewal is maintained after the works.
Smart thermostat
A smart thermostat can improve the control of the heating where it is compatible with the installation in place. In a home of modest size, programming makes it possible in particular to adjust temperatures according to when the home is occupied. This solution makes more sense when it complements a suitable heating system and a properly treated envelope, rather than when it is used on its own to compensate for significant heat losses.
Typical projects in Savigny-le-Temple
Terraced house heated by old electric heaters
the study can cover the exposed façades, the roof and the controls before determining whether the heating should be kept, improved or replaced by another solution.
Town house with an ageing gas boiler
the compactness of the property sometimes reduces certain losses, but the condition of the roof, the windows and the ventilation remains decisive. The project can combine improving the envelope with replacing the heat generator.
Flat in a 1980s development
the elements belonging to the individual home must be distinguished from the equipment or walls falling to the co-ownership. The scope for works then depends on the heating system and on the technical organisation of the building.
Financial support for your works in Savigny-le-Temple
Depending on its nature and on the situation of the property, a project may be eligible for MaPrimeRénov’ (the French state renovation grant), the CEE (energy saving certificates funded by energy suppliers), reduced-rate TVA (French VAT) or the éco-PTZ (an interest-free renovation loan). These schemes follow distinct rules and must be examined in relation to the works actually planned. To describe your home and set out the improvements you are considering, you can use the contact form so that the project and the schemes that may apply to it can be studied. The French public service France Rénov’ lists the schemes currently in force.
How we work
Reading the configuration
we identify the party walls, the exposed façades, the roof and the service spaces available.
Examining the existing heating
electric heaters, a gas boiler or another system are placed in the thermal context of the property.
Defining the priorities
the works are selected according to the most sensitive walls and the constraints on siting.
Coordinating the solutions
insulation, ventilation, heating and hot water are organised to work together.
Carrying out the agreed programme
the planned interventions are completed in accordance with the scope defined for the property.
We also work throughout the rest of Seine-et-Marne
You can also consult our pages devoted to Torcy, Villeparisis and Lagny-sur-Marne. To discover our approach across the wider area, see the page energy renovation in Seine-et-Marne.
Frequently asked questions
Should party walls be insulated in the same way as external façades?
Not in the same way. A wall adjoining a heated neighbouring home is generally less exposed than a façade giving directly onto the outside. The study must therefore treat each wall differently according to what lies on the other side, and concentrate the works on the surfaces that have a genuine thermal impact.
Can old electric radiators be replaced without redoing the whole house?
Yes, but it is preferable to know the performance of the envelope beforehand. New radiators do not put right a poorly insulated roof or façade. By studying the heating requirements and the condition of the building at the same time, it becomes easier to choose a system suited to the current situation.
Why can external insulation be more difficult on a terraced house?
Terraced houses often have property boundaries, aligned façades and a shared architecture. Adding a layer of insulation on the outside can therefore raise more constraints than on a detached house. Other insulation solutions can be examined where the configuration of the façades makes this type of work difficult.
Does a small house necessarily need small heating equipment?
Floor area alone is not enough to size the heating. Losses through the roof, the façades and the openings, the level of insulation and the temperature sought also influence the requirements. A compact home can perform relatively well or, on the contrary, lose a great deal of energy through a few poorly treated walls.
What should be checked before renovating a flat in a 1980s development?
The heating system, the ventilation, the status of the windows and walls and the equipment belonging to the co-ownership must first be identified. This check makes it possible to separate the works that can be carried out within the home from those requiring an intervention or a decision at building level.
To prepare an energy renovation in Savigny-le-Temple, tell us the type of property, its current heating and the works already carried out using the contact form. GRAM Énergie can then structure the various interventions around the technical particularities of your home.
