Duralis Energy is your partner to address your questions from the pre-project phase to optimization during the operational phase.
Thermal performance is engineered, not estimated.
We develop high-resolution heat balance models that define the exact energy demand of a building under real climatic and operational conditions. This analysis forms the regulatory backbone of the building permit process and the strategic foundation of long-term asset performance.
All assessments are executed in strict alignment with federal and cantonal legislation and SIA standards, including SIA 180 and SIA 380/1. Compliance is integrated into the model architecture, not appended afterward.
Our simulations incorporate envelope physics, thermal bridges, orientation, climatic datasets, solar radiation profiles, ventilation dynamics, and system efficiencies. The outcome is a fully quantified thermal behavior profile.
The result: reduced uncertainty, optimized capital allocation, and engineered performance with institutional-grade reliability.
Where architectural vision meets thermodynamic rigor. We engineer the internal environment to achieve peak efficiency and uncompromising climate control through high-fidelity physical modeling.
Our building physics services include:
As a State of Vaud-accredited Assistant Project Manager, Duralis Energy provides the institutional oversight necessary for complex building renovations. We lead the coordination of all technical and administrative stakeholders, ensuring project compliance from inception to delivery.
Our accreditation facilitates access to State of Vaud financial incentives, optimizing the project’s capital efficiency.
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.
Building permit application files are difficult and complex to put together. They have to comply with different points depending on the municipality or canton in which you are planning to build.
That is why we offer the possibility to take care of the energy dossier in order to save you time and energy, and to ensure you have a better chance of obtaining the building permit in the shortest possible time.
Learn MoreIn the same way as for the construction of the enquiry file, we offer the communes the service of checking the conformity of the investigation files with the laws and standards in force.
Learn MoreThere is no better way than a simulation to see how much you can save by improving your building. Our calculations will show you the effective loss of your buildings, the weaknesses, and on the contrary, the financial and energy gain that you can benefit from when changing your building.
Whether it is for solar panels, thermal energy or building optimisation, we are able to simulate the different scenarios in a consistent and reliable way.

A diagnostic tool that allows the detection of disorders invisible to the naked eye.
It allows, with an image taken as close as possible, to detect local thermal variations, and thus to visualise and highlight insulation defects not previously suspected. Conversely, it can demonstrate the presence of defects that are suspected.
In existing buildings, it can highlight the major defects to be treated as a priority. In new buildings, it can be a powerful tool for measuring the quality of a project.
As authorized experts, we guide you through Switzerland's energy certification landscape
Minergie is a Swiss construction label for new or renovated buildings. The label is supported by the business community, the cantons and the federal government. It is also protected against abuse.
Our office as a Minergie specialist partner supports its clients throughout the certification process. From the preparation of the application for the label to obtaining the final certificate.
Start Certification Process
We are qualified CECB experts and are authorised to issue energy certificates for buildings. We have extensive know-how in the field of energy audits of buildings and related optimisation measures.
The cantonal energy certificate indicates energy consumption for heating, hot water, lighting and electrical consumers in standard use.
Get CECB CertificateEnergy planning, which is compulsory in some Swiss cantons, aims to facilitate the integration of renewable energy and the creation of the necessary infrastructure for its use and distribution.
Carried out at the level of a district, a municipality, a canton or an entire region, "territorial energy planning" aims to reduce energy requirements through optimized spatial planning.
Municipalities can benefit from significant subsidies for territorial energy planning studies.
The subsidised amounts can reach 50% of the study costs, making comprehensive energy planning accessible to municipalities of all sizes.
