Air that takes care of itself

PIERRE turns ventilation into part of the house, not a forgotten switch on the wall. Fresh air when CO₂ climbs, quiet when the room is empty, coordinated with heating and cooling so the comfort stays even and the bill stays low.

The problem

Ventilation that nobody actually thinks about

Ventilation is one of those things you only notice when it is wrong. Stale rooms, loud fans at the wrong moment, recuperators fighting the AC. Most homes accept it because nothing else is on offer.

Stale air in the rooms that need it most

CO₂ climbs through the evening, the bedroom feels heavy by midnight, but the ventilation runs at a flat speed all day. Nobody gets up at 2 AM to adjust it.

Fan coils running blind

The unit runs at one speed because that is how it was set during install. Too loud for a quiet evening, too weak when the room is full. No middle ground.

Recuperator and AC fighting each other

The recuperator brings in cold air, the AC tries to warm it. Twice the energy for the same temperature.

A separate controller for each room

Every fan coil has its own knob on the wall. Every recuperator has its own panel. None of them read what the room actually needs.

How PIERRE solves it

Air managed by what the room actually needs

PIERRE reads the room and runs the air accordingly. CO₂, humidity, temperature, occupancy. Every fan coil, every recuperator, every duct moves together, not separately.

Demand-controlled ventilation

CO₂, humidity, and temperature sensors in every room. Fan coil and recuperator speeds adjust automatically to what the room is doing. Quiet when empty, stronger when it fills up.

Fan coil speeds, automatic

Low, medium, and high adjusted in real time. Low for a quiet bedroom evening, high after dinner with eight people in the dining room. Same set temperature, lower noise, lower energy.

Coordinated with heating and cooling

Recuperator, fan coil, AC, and heat pump all on one schedule. They stop fighting each other and start working as one system.

Per-room schedules

Bedroom drops to minimum during sleeping hours so it stays silent. Living room ramps up before guests arrive. Office stays neutral when nobody is in.

Scenes that include air

"Movie night" lowers fan speed in the living room for silence. "Cooking" pushes the kitchen ventilation up. "Sleeping" sets bedrooms to quiet and steady. One tap, the air follows.

Standard protocols, broad support

PIERRE talks to fan coils and recuperators through Modbus, 0-10V, and other open protocols. Most modern HVAC units integrate without proprietary boxes.

Ventilation scenarios

Each room, breathing on its own schedule

The bedroom, the kitchen, the living room, the office. Each one needs something different from the air. PIERRE follows the rhythm of each room without anyone having to think about it.

Bedroom at night

Bedroom at night

Steady, quiet, low speed. The CO₂ sensor watches the room. If it climbs, the fan steps up gently before anyone wakes up uncomfortable. Wake-up window opens ten minutes before the alarm.

Living room and dinner

Living room and dinner

Guests arrive, room fills up, CO₂ climbs, humidity rises. PIERRE bumps up the fan coil and the recuperator without anyone noticing. After everyone leaves, the system returns to idle.

Kitchen while cooking

Stove on, humidity and temperature rise. Kitchen ventilation pulls hard while the stove is active, then drops back ten minutes after cooking stops.

Office or studio

Office or studio

One person at the desk, low draw. Three people in a meeting, ramps up so heads stay clear. Returns to standby after the room empties.

Behind the scenes

The pieces that move the air

Fan coils per room, a recuperator in the utility room, sensors that read every corner of the house, and the PIERRE brain that decides what runs at what speed.
