Montpellier University Hospital: a radiant ceiling for the new geriatrics center
Summary for decision-makers
Reversible hydraulic ceiling: an innovative HVAC solution for healthcare facilities
The Montpellier University Hospital (CHU) has chosen the Acosi+ reversible hydraulic ceiling system for its new geriatrics and palliative care building. This system, which operates without forced air, improves air quality, reduces dust dispersion, and ensures quiet thermal comfort. Adapted to hospital constraints, it facilitates equipment installation, optimizes space, accelerates implementation, and allows for precise regulation to control energy consumption and prevent condensation.

The future geriatrics and palliative care center at Montpellier University Hospital will be equipped with Thermacome's Acosi+ reversible hydronic ceiling system. Selected to heat and cool 137 rooms, this fan-free solution meets the thermal comfort, indoor air quality, and integration requirements specific to healthcare facilities.
An alternative to forced-air air conditioning in hospitals
At the Colombière site, Montpellier University Hospital is constructing a new building dedicated to geriatrics and palliative care. To provide heating and cooling for the rooms, the engineering firm WSP 31 selected the Acosi+ reversible hydraulic ceiling system from Thermacome.
The choice of this technology is based in particular on the absence of air blowing. In a hospital environment, this characteristic helps to limit the dispersion of dust, allergens and microorganisms, while ensuring the comfort of patients and healthcare teams.
A radiant ceiling adapted to the constraints of healthcare facilities
The system operates at over 80% radiant heat , providing gentle warmth in winter and consistent coolness in summer, without generating any noise. Its integration into the ceiling frees up wall and floor space, facilitating the installation of medical equipment and movement within patient rooms.
According to Thermacome, Acosi+ is the only reversible ceiling on the market with a Technical Approval (ATEC) compatible with establishments open to the public (ERP), a criterion which also weighed in the choice of the solution.
An installation adapted to the constraints of the construction site
The project involves the installation of 1,980 m² of reversible hydraulic ceiling spread over three levels , supplied by 59 manifolds . The installation was carried out taking into account the numerous suspended equipment, including the patient lift rails present in the rooms.
Ultimately, the building will house 137 rooms , a reinforced accommodation unit as well as spaces for aging disabled people.
Accelerated implementation and continuous regulation
Thermacome states that the new generation of Acosi+ allows for installation twice as fast as previous versions. The system integrates without reducing ceiling height and requires no drying time, which can simplify project scheduling.
During operation, the water temperature can drop as low as 16°C for cooling. Continuous dew point monitoring adjusts operating conditions to prevent condensation and ensure occupant comfort year-round.
The choice of the Acosi+ reversible hydraulic ceiling by Montpellier University Hospital illustrates the growing interest in radiant heating solutions for healthcare facilities. Beyond thermal comfort, these systems address challenges related to indoor air quality, the integration of technical installations, and energy consumption control, while adapting to the specific constraints of hospital buildings.
