This distribution describes recorded buildings, not your system's consumption or efficiency.
| Energy | Heating | Hot water |

Each line gives the share of buildings using that energy, separately for heating and for hot water. The two columns do not always reach 100%: some buildings combine two systems, or reported none.
A standard non-condensing boiler is usually older and less efficient.
9.5 % of buildings mix housing with shops or offices.
For renovation planning in Écublens, official RegBL figures provide vital guidance. With 319 buildings listed as heritage protected out of 1021, contacting local authorities early is essential for permit compliance. Data coverage regarding building volume is partial, covering 209 of 507 houses under the SIA 416 standard with a median of 932 m3, which is critical for scaling heating and insulation upgrades accurately. Currently, no historical data is recorded regarding past renovation years for these properties. Please incorporate these insights when assessing your project requirements to ensure a smooth transition through the renovation process in this municipality.

Located at an altitude of 426 meters, Écublens experiences a climate with seasonal variations requiring a high-performance thermal envelope.5 °C, your roof is subject to significant thermal and mechanical stress.
An aging roof does not only lose energy; it allows moisture to enter, which can degrade the frame over the long term. The city's climate plan, aiming for carbon neutrality by 2050, emphasizes the importance of acting to reduce greenhouse gas emissions.
If your energy bill is rising or you observe leaks, it is time to consider refurbishment. Undertaking this work not only protects your structure but also aligns with the ambitious goals of the Energy City.
Roof insulation, combined with new coverage, radically improves indoor comfort, reducing dependence on heating systems given the 2759 heating degree days per year recorded in the region.
Roof renovation in Écublens offers various technical options depending on your energy and aesthetic goals. The choice of roofing materials, such as terracotta tiles, slate, or metal panels, directly impacts frost resistance and durability.
It is crucial to integrate high-performance thermal insulation when installing new roofing. Insulating the roof at the same time as the coverage is a recommended strategy that is often eligible for the Building Program.
Furthermore, if solar panels are considered, it is essential to plan their integration from the design phase. The removal and reinstallation of such panels must be carefully budgeted to avoid any surprises.
For homes located at this altitude, the weight of the materials must be taken into account based on potential snow loads.
Finally, under-roof ventilation remains an essential element to guarantee the longevity of the frame by preventing condensation, especially in a climate where temperature differences are frequent.
Discuss with your professional the solutions for drainage systems and wind protection that complement these technical installations.
The housing stock in Écublens is heterogeneous, and renovation challenges vary considerably depending on the construction period.
For buildings erected before the 1990s, special attention must be paid to the potential presence of dangerous substances such as asbestos, often used in old insulation or roofing materials.
A preliminary expert assessment is essential before any heavy intervention on the frame or roofing elements.
Buildings constructed before the era of modern energy standards frequently suffer from insufficient insulation, which results in significant heat loss.
During a renovation in Écublens, upgrading these infrastructures allows for meeting current standards while sustainably increasing the value of your property.
If the building is more recent, it may have technical networks integrated under the roof that will need to be protected during work.
Regardless of the period, always check the condition of the frame elements, as old leaks may have insidiously weakened the wood.
A detailed analysis by a local professional familiar with the Vaudois building stock is your best guarantee to identify risks related to the age of your home.
This guide does not establish a permit exemption. If your building or area is protected, check the constraints specific to your project.
It is imperative to submit your grant application before starting the work, as no funding is granted retroactively. In parallel, your taxation can be optimized.
The taxpayer can choose to deduct actual maintenance or energy investment costs, or opt for a flat-rate deduction. Investments intended to save energy are 100% deductible from your taxable income.
If your work exceeds the net income for a given year, you have the possibility to carry forward the balance of costs to the following two tax periods. This measure allows for spreading the tax burden related to large-scale projects.
Note, however, that it is not possible to combine the flat-rate deduction and the carry-forward of expenses.
Systematically check with the Vaudois tax administration before validating your financial strategy to ensure you maximize your deductions for insulation and renewable energies.
A roof renovation project in Écublens follows several key steps to ensure quality and safety. Everything starts with the planning phase, including authorization requests and grant applications.
Once permits are obtained, the construction schedule is established with craftsmen. The best season to start work is generally outside the frost period, although the local climate with 48 frost days per year requires rigorous organization.
The construction site often starts with the installation of safety measures and scaffolding. Then comes the removal of the old coverage, followed by the inspection of the structure. If necessary, repairs to the frame are carried out.
The crucial insulation step is carried out as a priority to benefit from grants. The installation of new coverage follows, then finishes and rainwater drainage systems are installed. Finally, the acceptance of the work allows for validating conformity.
Plan a close coordination phase with your contractors to anticipate weather issues, which are frequent in the region, to protect your home during the open roof phase.
To ensure the success of your renovation in Écublens, avoid some common errors. Never neglect thermal insulation in favor of mere aesthetics of the roofing.
Forgetting to check for the presence of asbestos in old materials is a serious error that can lead to significant additional costs during the construction process. Before requesting quotes, make sure you have a precise list of your needs.
Check if your roof is suitable for installing photovoltaic panels if you are considering this option. Always ask your companies to detail the costs for removing and reinstalling any technical equipment.
Verify that the companies consulted have the necessary certifications for insulation work. Ensure you have understood the aid you can claim by consulting the Building Program. Compare quotes that include the same services to avoid distorting the analysis.
Finally, never agree to start the work without having received written confirmation regarding the necessary municipal authorizations. This checklist will protect you against bad administrative and technical surprises.
