Duralis Energy is your partner to address your questions from the pre-project phase to optimization during the operational phase.
A thermal assessment determines the heating requirements for a building and provides an overall energy profile. It is required when applying for planning permission.
A building's thermal assessment must comply with the requirements set out in federal and cantonal energy laws and ordinances, as well as SIA standards, primarily: SIA Standard 180 'Thermal insulation and moisture protection in buildings', and SIA Standard 380/1 'Thermal energy in buildings'. As well as other laws specific to the cantons.
The calculation takes into account numerous factors such as exposure, insulation, wall surface area, geographical location, solar radiation, air exchange, and heating method, amongst others.
The thermal assessment will help you make the right choices, improve your building's energy performance and achieve energy savings.
The requirements that buildings must meet are constantly increasing. Sustainable construction and renovation involve a comprehensive planning process designed to optimise energy efficiency, indoor climate (temperature, air quality, lighting and acoustics), resource consumption and sustainability.
To address these challenges, the principles of building physics must be understood and applied, both inside and around the building, often by working with approximate solutions.
Compliance with regulations and energy optimisation of buildings
Application of SIA standards
Thermal comfort simulation
Specific issues: thermal bridges, mould, condensation

We are a Project Management Assistant (AMO) accredited by the Canton of Vaud. We will advise and support the client (MO) throughout the energy renovation of their building, from start to finish.
We support the client in defining the renovation project, selecting and coordinating contractors, planning, and handling the administrative procedures related to energy efficiency measures.
Our services as an accredited AMO are subsidised by the Canton of Vaud.
Navigating the multi-jurisdictional complexities of Swiss energy law with surgical precision. We ensure every project phase adheres to rigorous cantonal and federal standards to secure seamless authorization.
Planning application dossiers for building permits are difficult and complex to put together. They must comply with different requirements depending on the municipality or canton in which you plan to build.
That is why we offer to take charge of compiling the energy dossier to save you time and energy, and to ensure you have the best chance of obtaining your building permit as quickly as possible.
Learn MoreThere is no better way than a simulation to assess the actual savings generated by building improvements. The calculations we carry out highlight actual energy losses, weak points, and the expected energy and financial gains resulting from the proposed measures.
Whether it involves the installation of solar panels, thermal energy generation solutions or the overall optimisation of the building, we are able to simulate various scenarios in a consistent, reliable and accurate manner.

Infrared thermography is a powerful diagnostic tool for detecting defects invisible to the naked eye.
It highlights heat loss, insulation defects and building anomalies by analysing surface temperature variations.
Used in both existing and new buildings, it enables us to identify weak points in the building envelope, detect air or moisture infiltration, locate leaks or insulation defects, check the quality of work carried out, and identify electrical faults or issues with the wiring.
Result: a precise and rapid assessment to identify priority actions and improve the building's energy performance.
As authorized experts, we guide you through Switzerland's energy certification landscape
MINERGIE® is a Swiss quality label for new buildings and renovations, guaranteeing a high level of comfort, excellent energy efficiency and increased use of renewable energy.
As a specialist MINERGIE® partner, our firm supports clients and architects through every stage of the certification process, from project planning and preparation of the application dossier to obtaining the MINERGIE® certificate.
We ensure that the label's requirements are incorporated from the design phase onwards to optimise the building's energy performance and comfort.
Start Certification Process
We are qualified CECB experts authorised to issue energy certificates for buildings. Drawing on our expertise, we analyse the energy performance of buildings and identify measures to improve their energy efficiency.
The CECB assesses a building's energy consumption for heating, domestic hot water, lighting and other electrical uses. It allows the energy performance of a building to be compared with that of other similar buildings.
In many cases, particularly for energy-efficient renovation projects or when applying for grants under the Buildings Programme, a CECB Plus assessment is required. This assessment sets out several renovation scenarios and identifies the most effective energy-saving improvements.
We support property owners, architects and project owners with energy audits of buildings and the planning of optimisation measures.
Get CECB CertificateRegional energy planning aims to optimise energy use across a region and promote the integration of renewable energy. In some Swiss cantons, this approach has become an essential tool for guiding the energy development of municipalities.
Coordinates production, recovery and distribution networks for a coherent, future-proof energy infrastructure.
Optimises building orientation, urban densification and proximity to renewable sources and waste heat recovery.
Applied from neighbourhood to regional level — reducing demand and building a sustainable, resilient energy supply.
Municipalities may be eligible for grants to carry out these studies, with funding covering up to 50% of the study costs.
Reduce your energy costs and optimise your site's performance in a sustainable way.
In Switzerland, energy audits are mandatory for sites with an annual consumption exceeding approximately 0.5 GWh of electricity or 5 GWh of thermal energy.
This audit enables you to quickly identify sources of energy loss, quantify potential savings and define concrete, high-impact actions.
Fewer losses, greater efficiency and decisions based on reliable data.
