HESA Hybrid ceiling islands

Every building uses climate-control systems. The air in which you are, everything you breathe in and out, the entire indoor climate determines your comfort, your health and your performance. The low-energy hybrid climate ceiling creates and produces this wonderful climate comfort.

Hybrid ceiling islands can be used during new-build and renovation projects for:

  • Offices
  • Hotels
  • Hospitals
  • Schools
  • Modular buildings
  • Renovation projects

The design principle is the wish for a specific building layout with separate rooms; how large are the units where an island can be fitted and what are the requirements for ventilation, cooling and heating.

Depending on the use of the room, a hybrid ceiling island design is determined by the level of fresh air supply, the control system and the physical dimensions.

Operation of HESA

HESA has an air intake for supplying ventilation air. This air intake has a number of nozzles to achieve a decentralised supply of ventilation air. Near the air intake, an intake opening has been created for the recirculation air. Air from the room is drawn in via the intake opening, because a local underpressure is created by the ventilation air from the nozzles. This mixed air is cooled or heated at the upper side of the panel. In case of a concrete ceiling or floor, the heat or cold can be stored in the concrete and then withdrawn depending on the need.

Recirculation produces a significant capacity increase for the hybrid climate ceiling, without jeopardising the benefits associated with the radiation and convection of a traditional climate ceiling.

The term hybrid refers to a combination of technologies that together produce a better result. By activating the upper part of the ceiling island heat or cold is transferred to the building structure. The purpose of this is to store energy in the building structure. Energy transfer by radiation during climate control continues to be the operating principle of the hybrid ceiling island.

Overnight, when the air supply has stopped, the energy is only charged into the building structure and during daily use this energy becomes available. This means the total climate-control system can be approximately 10% smaller.

By supplying fresh air, air from the room is put into motion, which ensures that the hybrid climate ceilings generate additional heat output, in other words heat transfer by means of air flowing past.

The hybrid ceiling island of Solid Air, HESA:

  • Best-performing hybrid ceiling island in the Dutch market.
  • Has 30% more capacity than traditional ceiling islands.
  • The solution for renovation projects that deal with a relatively small build-in height.
  • Fully integrated components, such as lighting, audio and presence sensors.
  • Highest comfort class.
  • Ventilate, cool and heat in one.
  • Completely unburdened from specs to completion.

Versions of our hybrid ceiling island: HESA

HESA can be supplied and fitted in many different models and versions at the project. Depending on the needs and requirements of our client, HESA provides room for components such as lighting, audio, presence sensors and sprinklers.

We like to consider your needs and act as your partner when the islands are designed, including with respect to the manner in which they integrated into the building's systems.
A capacity and comfort test is carried out on request. This test is performed by independent firms and in accordance with applicable European standards, such as EN 7730.

Room control

HESA is very convenient to control with standard control systems. The air quality (CO2/VOC*) and the room temperature can be controlled in combination with optimum energy savings.

HESA stands for:

H climate ceiling
E island shape
S self-supporting
A standard perforation 16%

Insulation blanket

Insulation thickness: variable
Insulation pressing: variable
material: mineral wool with black PE film
fire-safe: CE marked


The HESA activation pipes are made of copper (Cu) with dimensions of 8 x 0.6 mm, clipped into aluminium profiles. Often based on the usual basic colours, such as RAL 9016 and RAL 9010. Other RAL colours available on request
