QLIMATE: Heating, Ventilation & Air Conditioning - HVAC

A new identity for a strong vision

Since December 2024, QLIMATE has had a name that symbolizes its transformation. The company, which emerged from Zehnder Climate Ceiling Solutions, thus asserts its independence and its ambition: to become a major player in the thermal comfort by radiation in France and in Europe.

Based at Evry (Essonne), QLIMATE relies on around twenty employees and industrial know-how shared between France and Germany. Its production and research and development center are located in the Black Forest, near Strasbourg. This dual location illustrates a balance between European industrial expertise 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 — sleek capital letters topped with a horizontal bar — evokes the harmonious duality between hot and coldIts 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 are based on the principle of natural radiation, similar to that of the sun. Unlike forced-air systems, heat or coolness diffuses evenly without stirring, noise, or drafts. The result: consistent, quiet comfort that respects the health of 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 is based on a network of tubes hidden in the false ceiling, where hot or cold water circulates depending on the season. The system is controlled by a reversible heat pump or an condensing boilerThe very low operating temperature (32–35°C for heating, 16–18°C for cooling) allows maximum performance and high compatibility with renewable energies.

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 is based on integrated heating films or cables in panels. Ideal for buildings without central heating, it only provides heating, not cooling. This system nevertheless retains the advantages of radiation: homogeneity and silence.

A discreet architectural integration

QLIMATE climate ceilings integrate perfectly into contemporary architectureInvisible, they give architects complete freedom of design: no grid, no visible elements, no aesthetic constraints. The installation, with its low thickness, is suitable for both new construction and renovation.

A comprehensive offer designed for prescribers

QLIMATE stands out for its integrated approach that meets the requirements of tertiary market : performance, comfort and ease of implementation. The company does not limit itself to supplying equipment: it supports specifiers and project owners at every stage of the project.

Integrated design office

Le internal design office carries out thermal studies, sizing and simulations personalized. This expertise guarantees the match between the performance of the climate ceiling and the architectural constraints of the building. Specifiers benefit from a single point of contact to validate technical solutions and anticipate installation constraints.

“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. The ceilings are custom-made in the company's workshops, delivered on a just-in-time basis and installed according to a precise protocol guaranteeing the quality and compliance of the assembly. This “turnkey” control secures deadlines and optimizes the overall budget of the project.

Support, training and documentation

QLIMATE also supports installation companies and engineers with technical training and Team prescription supports : product sheets, case studies, demonstrations, and simulation tools. These resources facilitate the integration of climate ceilings into complex projects, while promoting the development of skills among professionals in the sector.

QLIMATE technologies: performance and durability

QLIMATE hydraulic ceilings are based on technology very low temperature and intelligent regulation to ensure constant 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 meet the challenges of sustainable construction : reduction of the carbon footprint, integration into positive energy buildings (BEPOS) and compatibility with low-carbon generators (PAC, solar thermal). The absence of mechanical ventilation also limits particle emissions and the need for maintenance.

Demanding prescribers, a tailor-made response

Architects and design offices

Architects are looking for solutions aesthetic, silent and flexible. QLIMATE meets this expectation by offering modular, discreet climate ceilings adapted to each type of space. Technical design offices appreciate the rigor of the thermal performance data and the compatibility with environmental standards (RE2020, HQE, BREEAM).

Public and private project owners

Project owners favor robust, economical and durable systems. QLIMATE solutions guarantee them reduced maintenance and total sustainable energy efficiency, contributing to the heritage enhancement of the building.

Construction companies and installers

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

Thermal engineers and energy experts

These prescribers are looking for solutions capable of stabilize the temperature without perceptible variationsQLIMATE ceilings meet these requirements thanks to their fine regulation and predictable thermal behavior, validated by numerous simulations.

A digital showcase for partners

QLIMATE will take a new step 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 ;
• des prescription support tools and sizing;
• a highlighting of iconic achievements.

This site will mark the company's desire to offer a seamless digital experience, reflecting the quality of its technical solutions.

QLIMATE, a key player in French climate engineering

By conjugating independence, innovation and know-how, QLIMATE embodies a new generation of French industrial companies. Its approach combines technical requirements and environmental responsibility: two essential pillars for the buildings of the future.

His expertise in hydraulic climate ceiling makes it a privileged partner for project owners and architects who wish to reconcile comfort, energy performance and sustainability.

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

With its strong roots and forward-looking vision, QLIMATE is now establishing itself as a strategic player in climate engineering in France, with a clear ambition: to make sustainable comfort accessible to all tertiary buildings.
