An outdoor heat pump unit and a ventilation housing on a flat roof

IT company

Heating and cooling 1,500 m² of offices

Client: IT company
Services: Study, installation, commissioning
Key figure: 1,500 m² heated and cooled

The problem

An IT company gives off a lot of heat. In summer the space had to be cooled, and in winter 1,500 m² had to be heated. Two needs, one building, no room for error.

What we did

Floor cooling in summer and heating in winter, where the equipment gives off the most heat
Hydronic radiators in the offices, releasing heat at high temperature
A brand chosen for its resistance to outdoor conditions and a high-power system: Mitsubishi
A study, then installation, then commissioning

The project in detail

How the job went

The context

An IT company is a building that never really cools down on its own. Servers, workstations and screens give off heat all day, so in summer the first job was to take that heat out of the space, and in winter the same 1,500 m² had to be heated properly. Two opposite needs in one building left no room for a compromise: a system that only heats would leave the team too hot in July, and one that only cools would leave them cold in January. Before drawing anything, we went to the site and looked at where the equipment sits, because that is where the heat is released and where cooling matters most.

Our work

The answer we studied was a floor that does both. Water runs through the slab: cooler in summer to absorb the heat of the room, warmer in winter to give heat back. A floor works at gentle temperatures, so it is quiet, invisible and even, with no draught and no unit hanging on a wall. In the offices we added hydronic radiators, which release their heat at a higher temperature where people actually work. The heat source had to be powerful and had to withstand outdoor conditions all year round, so we chose Mitsubishi for this site. Then we followed the sequence we follow everywhere: first the study, then the installation, then the commissioning, with every setting checked before handing over.

The result

What the client gained is simple to describe: one system, 1,500 m², comfortable all year, cool in summer and warm in winter. Nobody has to switch between two installations or look after two sets of equipment, and the people who work there can forget about the temperature, which is what a good system should allow. The lesson is the one we repeat on every job: size the system for the real building, choose the brand for the real conditions and test everything before leaving. If you have a space where equipment gives off a lot of heat, we will start the same way, with a visit and an honest study.

What changed

A single system now keeps 1,500 m² comfortable all year round: cool in summer, warm in winter.
