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.
For homeowners in Renens, RegBL figures provide essential benchmarks for planning your renovations. While the status of heritage protection is known for 114 buildings, with one officially protected, contacting the municipality early is vital to navigate permit requirements. The median building volume of 800 m3, derived from 123 houses measured under the SIA 416 standard, helps estimate the scale of necessary heating or insulation upgrades. Please be aware that data coverage is partial, as 599 buildings utilize other or unknown standards, which is a key factor to consider when evaluating the scope and budget of your renovation project.

5 °C and about 48 frost days per year at an altitude of 420 meters, the climate in Renens places significant demands on heating systems. The local building stock faces growing requirements for decarbonization.
Installing a heat pump not only helps to move away from fossil fuels but also meets the objectives of the local Climate Plan, which strongly encourages the reduction of fossil energy consumption.
The ideal time to replace your heating system is generally before your current boiler breaks down completely or during a comprehensive building renovation. By anticipating these works, you avoid making decisions under pressure.
Furthermore, the municipality aims for a significant increase in the share of local renewable energy, making the installation of a heat pump a step consistent with the energy vision for 2035 and 2050 for the entire territory of Renens.
The choice of heat pump system depends on several crucial technical factors. For air-water installations, it is mandatory to respect the noise limits imposed by legislation to protect the neighborhood.
Since the required power is determined by the local design outside temperature, a rigorous calculation is essential to ensure equipment efficiency.
There are various options, from high-performance models to hybrid systems. It is essential to check if your home is compatible with low-temperature heating, which maximizes the heat pump's performance coefficient.
Materials and product ranges vary based on specific domestic hot water needs and the building configuration.
A preliminary study by a professional allows for adjusting the technical choice, thus ensuring that the installation will perform well even during the coldest periods of the year in Renens.
The building stock in Renens presents varied profiles, ranging from older constructions to more recent buildings. For structures built before 1990, it is common to encounter insufficient insulation or distribution networks that require an update.
These elements can impact the heat pump sizing. An energy audit is often recommended to assess whether insulation work on attics or window replacement is necessary before installation.
It is also necessary to remain vigilant regarding potentially hazardous materials in old structures. Furthermore, the configuration of existing distribution networks, if they were designed for high temperatures, may need to be optimized.
Each type of construction imposes different constraints in terms of space for the outdoor unit, especially in dense urban areas.
By precisely assessing the thermal performance of your current housing, you will be able to better adapt the system to the realities of your structure.
This guide does not establish a permit exemption. If your building or area is protected, check the constraints specific to your project.
It is crucial to note that the grant application must be submitted before the start of the work to be eligible.
Regarding taxation, the taxpayer can deduct 100% of energy investment costs in the tax return. In case of negative net income, these costs can be carried forward over the next two tax periods.
However, note that if the work is subsidized, only the portion remaining at the owner's expense is deductible.
The taxpayer has the choice between deducting actual costs or a flat-rate deduction for maintenance, but claiming actual costs is often more advantageous for major energy renovation projects.
The schedule for a heat pump installation begins with a diagnostic and planning phase. It is advisable to check the connection to the priority district heating network, if applicable, as this can be a relevant alternative in Renens.
Once the technical choice is validated, administrative procedures for authorizations are initiated.
The project itself includes the dismantling of the old system, the installation of the new unit, and the connection to the hydraulic and electrical networks.
The optimal period to carry out these works is outside of extreme cold periods, ideally in spring or summer. This allows for commissioning and necessary adjustments without stress for the occupants, anticipating needs for the following winter.
A final test phase ensures the sizing is correct in relation to the local design temperature.
Do not neglect the acoustic study of your installation, as noise is a frequent source of dispute. Ensure you have checked if your neighborhood can be connected to district heating, as this solution may be prioritized according to local strategy.
It is also risky to underestimate the required power by ignoring the local design temperature. Do not sign any quote before submitting your grant application to the Buildings Program.
Finally, systematically check the constraints of your heritage area or any potential protections related to your building.
Checklist before requesting quotes : 1. Check the availability of the district heating network. 2. Have a thermal audit of your home carried out. 3. Identify the noise level allowed in your neighborhood. 4.
