Situated at an altitude of 685 meters, the municipality of Brig-Glis presents specific climatic challenges for property owners.4 °C, thermal comfort and building envelope performance are crucial.

The 62 days of frost per year require rigorous insulation to maintain a stable indoor temperature while limiting heating needs, estimated at 3019 Kj/year (20/12 °C).

The building stock in Brig-Glis requires upgrades to meet modern standards. The alpine climate demands increased vigilance regarding moisture management and the quality of exterior materials.

The city, which has been awarded the Gold Energy City label, actively encourages residents to improve the energy efficiency of their buildings.

By anticipating local climate effects during your renovation work, you ensure not only the long-term durability of your structure but also a significant reduction in your operating costs over time.

Energy renovation in Brig-Glis focuses primarily on improving the building envelope. Façade insulation and window replacement are the first line of defense against heat loss.

By optimizing these elements, you drastically reduce heating demand and improve living comfort. Given the 62 annual days of frost, a high-performance envelope is essential to minimize energy consumption.

Additionally, the installation of solar systems is encouraged. With an annual global irradiation of 1477 kWh/m²/year, the photovoltaic potential is high. A well-dimensioned installation on a south-facing roof can reach an estimated yield of 1300 kWh/kWp/year.

It is recommended to prioritize a holistic approach : insulate first to reduce demand, then install renewable energy production equipment to meet residual demand.

This strategy increases the value of your property in line with the goals of the 2050 energy strategy, which aims for 100% coverage by renewable heat and cold in the region by 2050.

This network, which utilizes groundwater, offers a sustainable heating solution. It is imperative to inquire about the service area and technical connection conditions to determine if your property can benefit.

For buildings outside the connection area, the installation of heat pumps is a preferred alternative. Valais actively supports this energy transition through the Building Program, which offers flat-rate contributions for the installation of renewable systems.

These subsidies aim to assist owners in replacing obsolete boilers. Although the targets of 75% renewable heat by 2035 and 100% by 2050 are not binding obligations for each individual, they strongly influence technological choices during renovation.

Always check the compatibility of your project with local regulations concerning the use of groundwater resources.

Whether it concerns work on the envelope, changes affecting the exterior appearance (such as window replacement), or the installation of solar panels, adherence to local procedures is essential.

The municipal public works department is your primary point of contact for understanding current urban planning requirements.

The built heritage of Brig-Glis is valuable, and some areas may be subject to strict heritage protection guidelines. When planning renovations, particularly for façades or roofs, it is recommended to check if your property is registered.

Cantonal and municipal authorities ensure that interventions respect architectural harmony. Anticipate these steps before signing work contracts.

Preliminary consultation often helps to avoid rejections or costly modifications after construction begins, thus ensuring the success of your project while durably maintaining the aesthetic and historical value of your property.

These aids aim to make energy investments more accessible. It is recommended to consult the official website before starting any work to understand current rates and eligibility conditions.

Regarding renewable energy, the federal one-off remuneration via Pronovo encourages the installation of photovoltaic systems. Some Valais municipalities also offer additional premiums that complement this base.

Finally, do not forget the tax aspect : renovation work aimed at energy efficiency is generally deductible from your income tax. Keep all your invoices carefully, as they are essential for justifying these deductions.

This financial planning, combining direct subsidies and tax advantages, helps to optimize the overall cost of your work while increasing the value of your real estate in Brig-Glis.

A successful renovation begins with rigorous planning. Before contacting companies, carry out an energy audit to identify the weak points of your home.

In Brig-Glis, prioritize local contractors who are familiar with the climatic specifics and regulations in force in the region. Their experience is an asset for meeting deadlines and ensuring the quality of services.

For each work package, request several detailed quotes and compare them. Ensure that companies have the necessary certifications to access cantonal aid, particularly for thermal or photovoltaic installations.

A good choice of company is based not only on price but also on references, proposed guarantees, and a comprehensive understanding of your project.

Establish a coherent work schedule, taking into account the weather conditions in Brig-Glis, especially for exterior interventions.

Clear communication with your contractors throughout the project helps to anticipate unforeseen issues and ensure compliance with standards, thus ensuring the long-term success of your real estate renovations.
