A new identity for a strong vision

Since December 2024, QLIMATE has borne a name that symbolizes its transformation. The company, which originated from Zehnder Climate Ceiling Solutions, thus affirms its independence and its ambition: to become a major player in radiant thermal comfort in France and Europe.

Based in Évry (Essonne) , QLIMATE relies on around twenty employees and industrial expertise shared between France and Germany. Its production and research and development center are located in the Black Forest, near Strasbourg. This dual presence illustrates a balance between European industrial mastery and operational proximity to the French market.

“With QLIMATE, we have a clear vision: to combine comfort, energy efficiency and technical excellence in all commercial buildings,” explains the company’s management.

A visual identity that carries meaning

The QLIMATE logo — clean capital letters surmounted by a horizontal bar — evokes the harmonious duality between hot and cold . Its cobalt blue and champagne palette illustrates the brand's mastery of all thermal needs: efficiency, stability, and elegance.

Climate ceilings for sustainable comfort

The principle of thermal radiation

QLIMATE climate ceilings operate on the principle of natural radiation , similar to that of the sun. Unlike forced-air systems, heat or coolness is diffused evenly without movement, noise, or drafts. The result: consistent, silent comfort that respects the health of the occupants.

This technology offers up to 40% energy savings compared to traditional solutions, while guaranteeing a stable and pleasant thermal sensation.

The two major technological families

The hydraulic heated ceiling

This is the flagship technology of QLIMATE installations. It relies on a network of pipes concealed within the false ceiling , through which hot or cold water circulates depending on the season. The system is controlled by a reversible heat pump or a condensing boiler . The very low operating temperature (32–35 °C for heating, 16–18 °C for cooling) allows for maximum performance and excellent compatibility with renewable energy sources.

This radiant diffusion method eliminates stratification and air displacement. It promotes stable comfort in all areas of a space, whether it is an open plan office, a classroom, or an operating room.

“The QLIMATE climate ceiling creates a natural comfort experience, close to solar heat, without the nuisance of blown air systems,” emphasizes a partner thermal engineer.

Electric ceiling heating

Easier to install, it relies on heating films or cables integrated into panels. Ideal for buildings without central heating, it only provides heating, not cooling. However, this system retains the advantages of radiant heating: even heat distribution and quiet operation.

A discreet architectural integration

QLIMATE climate ceilings integrate seamlessly into contemporary architecture . Invisible, they offer architects complete design freedom: no grids, no visible elements, no aesthetic constraints. Their slim profile makes them suitable for both new construction and renovation projects.

A comprehensive offer designed for prescribers

QLIMATE stands out for its integrated approach that meets the demands of the commercial building market : performance, comfort, and ease of implementation. The company goes beyond simply supplying equipment; it supports specifiers and project owners at every stage of the project.

Integrated design office

The in-house design office conducts customized thermal studies, sizing calculations, and simulations . This expertise ensures that the performance of the climate ceiling is perfectly aligned with the building's architectural constraints. Specifiers benefit from a single point of contact to validate technical solutions and anticipate installation challenges.

“Our technical support from the design phase ensures consistency between architectural ambitions and energy objectives,” explains the QLIMATE team.

Complete control of the value chain

Manufacturing, logistics, and installation are entirely managed by QLIMATE and its qualified partners. Ceilings are custom-made in the company's workshops, delivered on a just-in-time basis, and installed according to a precise protocol that guarantees quality and conformity of the installation. This turnkey approach ensures on-time delivery and optimizes the overall project budget.

Support, training and documentation

QLIMATE also supports installation companies and engineers with technical training and specification materials : product sheets, case studies, demonstrations, and simulation tools. These resources facilitate the integration of climate ceilings into complex projects, while promoting the professional development of industry professionals.

QLIMATE technologies: performance and durability

QLIMATE hydronic ceilings utilize ultra-low temperature technology and intelligent control to guarantee consistent thermal comfort throughout the year. This system reduces energy consumption while providing a healthy and quiet environment.

Technology suitable for all types of buildings

QLIMATE solutions are deployed in:

• the office buildings and coworking spaces;
• the educational institutions and university campuses;
• the hospitals and nursing homes ;
• the administrative buildings ;
• certains hotels and cultural facilities.

A sustainable alternative to traditional systems

QLIMATE climate ceilings address the challenges of sustainable construction : reducing carbon footprint, integrating into positive energy buildings (BEPOS), and compatibility with low-carbon energy sources (heat pumps, solar thermal). The absence of mechanical ventilation also limits particulate emissions and maintenance requirements.

Demanding prescribers, a tailor-made response

Architects and design offices

Architects are looking for aesthetically pleasing, quiet, and flexible solutions . QLIMATE meets this need by offering modular, discreet climate ceilings adapted to every type of space. Engineering firms appreciate the rigorous thermal performance data and the compatibility with environmental standards (RE2020, HQE, BREEAM).

Public and private project owners

Building owners prioritize robust, economical, and sustainable systems. QLIMATE solutions guarantee reduced maintenance and long-term energy efficiency , contributing to the building's value.

Construction companies and installers

These professionals benefit from continuous operational support : technical assistance, site monitoring, and installation training. The goal is to guarantee optimal execution quality and lasting performance.

Thermal engineers and energy experts

These specifiers are looking for solutions capable of stabilizing the temperature without perceptible variations . QLIMATE ceilings meet these requirements thanks to their precise regulation and predictable thermal behavior, validated by numerous simulations.

A digital showcase for partners

QLIMATE will reach a new milestone with the launch of its website in March 2025. A true reference platform for prescribers, this site will offer:

• another clear presentation of the ranges ;
• direct access to data sheets et case studies ;
• some prescription support tools and sizing;
• a highlighting of iconic achievements.

This site will reflect the company's commitment to providing a seamless digital experience , mirroring the quality of its technical solutions.

QLIMATE, a key player in French climate engineering

By combining independence, innovation, and expertise , QLIMATE embodies a new generation of French industrial companies. Its approach blends technical excellence with environmental responsibility: two essential pillars for the buildings of the future.

Its expertise in hydraulic climate ceilings makes it a preferred partner for project owners and architects who wish to combine comfort, energy performance and sustainability.

“QLIMATE is the alliance of natural radiance and technological mastery in the service of collective well-being.”

With its solid roots and forward-looking vision, QLIMATE has established itself as a strategic player in climate engineering in France , with a clear ambition: to make sustainable comfort accessible to all commercial buildings.
