Our Trias Energetica: 3 guiding principles for your renovation projects

Reduce energy needs through active heat and cold recovery and smart ventilation systems.

Use natural resources by passively cooling rooms without any unwanted heat exchange.

Minimise energy consumption by adaptively using available sources of energy through heating and cooling in the home.

Long-term solutions instead of quick fixes.

In many cases, indoor air is five times as contaminated as it is outside. Unless of course you make the right decisions.

Less moisture. Healthier home.

Moisture is difficult to avoid — and with it comes the risk of mould. Yet in many renovation projects, this issue is often overlooked. Learn more about the impact of mould spores on indoor air quality and explore solutions to support a healthier, more resilient home.

How you can prevent mould

No energy loss. 
No problem.

If your renovation is not energy-efficient, you are wasting valuable resources, money and time. With Zehnder, you will have already factored in at the planning stage how your renovation measures will allow you to reduce energy costs, use natural sources and integrate heaters and other devices elegantly in your home.

Stay cool. 
When the heat is on.

Rooms heat up very quickly, especially in the summer months. To avoid this, we have developed ventilation systems that keep your home cool, comfortable and the indoor climate pleasant – without expensive, energy-intensive air conditioning.

Real renovation stories. Real results.

Renovation is never a one-size-fits-all solution. That’s why professionals across the world trust Zehnder for expert advice, reliable technology, first-class quality and real partnership. These international case studies show how real challenges can lead to holistic solutions for maximum energy efficiency, health and comfort.

Comfort, health and energy efficiency
in anewly built family house

Since 2021, the Henninger-Dorer family have been living in a dapper one-family house in the idyllic surroundings of Weisweil, near the French border. To keep pollen, insects and spores out of their house while still ensuring a plentiful supply of fresh country air, they opted for a central ventilation system from indoor climate specialists Zehnder.

Historic renovation: customised radiators
for the city museum

When the listed building was renovated completely, the architects and planners integrated state-of-the-art heating technology. A total of 43 Zehnder radiators were installed in the new city museum, where tiled stoves and earthenware were once made. Zehnder radiators now grace the museum building.
