Renovations, heritage and volumes

For your renovation projects in Pully, RegBL figures provide essential benchmarks. With 6 buildings identified as protected heritage out of 126 known properties, contacting the municipality early is vital to secure your permits. The median house volume is 1165 m3 according to SIA 416, which is crucial for scaling your insulation works or heating system upgrades. Please note that data coverage is partial, as the volume is only measured for 126 houses out of 612 recorded in the municipality. These metrics help you assess the scale of your construction work and accurately estimate renovation costs for your home.

The local context: climate and specifics of Pully

6 °C.2 °C. These conditions require special attention regarding thermal insulation and the performance of heating systems to maintain optimal interior comfort during the cold season.

The real estate stock of Pully, with its 18,000 inhabitants, presents a diversity of typologies requiring tailored approaches. The global sunshine, estimated at 1,363 kWh/m²/year, offers interesting potential for the energy transition.

Building management must adapt to these climatic realities to ensure the sustainability of structures and limit energy losses, while leveraging local solar resources.

Energy renovation priorities

Energy renovation in Pully is in line with the City's Energy Concept, adopted in 2015. The primary objective is to reduce consumption by intervening primarily on the building's thermal envelope.

Facade insulation and window replacement are the pillars of this strategy. A high-performance envelope not only lowers heating needs but also increases property value in the long term.

Insulation work is supported through the Building Program, which offers contributions per square meter of insulation. It is essential to include a global reflection: changing only the windows without insulating the walls can create thermal imbalances.

Owners are invited to assess the current state of their insulation to target the most energy-efficient interventions.

By improving building efficiency, dependence on fossil energy sources is reduced, aligning with municipal and federal sustainability standards.

Heating and district heating

The heating system is a major aspect of renovation. Pully prioritizes the development of renewable energies and encourages connection to district heating.

This network, operated by the City of Lausanne, uses renewable resources, heat from the lake, treated water from the future Pully treatment plant, thermal energy from the TRIDEL waste plant, wood, and geothermal energy.

The south of the municipality is the priority zone for this connection.

For areas not served, installing a heat pump is a promoted alternative. Subsidies for replacing fossil fuel heating with a heat pump are available through the Building Program.

Procedures for installing air-to-water or air-to-air heat pumps are simplified, although checks on noise nuisance are carried out.

This transition to low-carbon systems is crucial to achieving the goals of the 2050 Energy Strategy and aligns with the pragmatic policy led by the City of Pully for 25 years.

Permits and heritage

This guide does not establish a permit exemption. If your building or area is protected, check the constraints specific to your project.

Financial aid and taxation

The Building Program, coordinated at the cantonal level, offers subsidies for replacing fossil fuel heating with a heat pump, thermal insulation, and the installation of solar thermal systems.

Furthermore, a federal one-off remuneration is available for photovoltaic installations, complementing cantonal aid. It is crucial to submit the application before starting work to hope to receive this aid.

On the tax front, the canton of Vaud offers advantageous flexibility. Owners can choose, each year and per building, between the deduction of actual maintenance costs and a flat-rate deduction.

Investments aimed at saving energy or using renewable energies are 100% tax-deductible. If these costs exceed net income, the balance can be carried forward to the following two tax periods.

This measure allows for optimizing the financial planning of work over several years, thus promoting ambitious renovation projects while managing the tax burden.

Planning and selecting companies

Successful renovation in Pully requires a rigorous methodology. The first step is to establish an energy audit to identify the weaknesses of your property., facade insulation coupled with window replacement).

This global approach optimizes labor costs and limits repeated nuisances. It is advisable to request several quotes from qualified local companies to compare the services and guarantees offered.

The selection of companies must take into account their experience in the type of renovation envisioned, particularly for work related to energy performance. Check references and ensure that the contractors master current cantonal and federal standards.

Structured planning including material delivery times and artisan availability allows for meeting the schedule.

By collaborating with knowledgeable professionals, you ensure not only quality execution consistent with local expectations, but also the proper management of administrative procedures and associated grant applications.
