Business hotel, 88 rooms
Central room management, an arrival scene triggered on first badge, addressable fire detection and energy supervision by zone.

- 88 rooms and public areas
The brief
What the building demands
- 01A building that never closes: no intervention may interrupt operation
- 02Ending the habit of cooling 88 rooms when half are empty
- 03Fire safety beyond reproach, since it is the condition of operating at all
- 04Front desk staff able to act without an engineering background
The architecture
The response, layer by layer
The same order of dependency as on every project we run: energy first, supervision last. Each layer links to the discipline that handles it.
- 01ENERGYEnergy
Metering by zone and by use, with photovoltaic generation covering the daytime base load of the public areas. Discipline
- 02ELECTRICALElectrical
Redundancy on vital circuits — lifts, security, IT — with changeover the guest never notices. Discipline
- 03NETWORKNetworks
Guest and operations networks strictly separated, with coverage validated room by room by measurement. Discipline
- 04SECURITYSecurity
Video protection of circulation and entrances, retention calibrated on the legal period and no longer. Discipline
- 05ACCESSAccess control
Online locks, rights expiring at checkout, staff access traced by service zone. Discipline
- 06FIREFire
Addressable detection to EN 54 and ISO 7240, compartmentation interlocks, reporting to reception and to security. Discipline
- 07AUTOMATIONAutomation
Arrival scene on first badge, energy isolation when the guest leaves, setpoints bounded by the operator. Discipline
- 08MONITORINGSupervision
Energy supervision by zone, drift alerts and monthly operating reports.
Technologies
What we bring to bear
- KNX
- DALI-2
- EN 54
- ISO 7240
- IEEE 802.11ax
- Modbus TCP
Open, documented standards rather than closed systems: an installation must remain serviceable and extendable by another integrator.
In use
What this architecture produces
- An empty room stops consuming: energy follows real occupancy.
- The guest walks into a room already at temperature and already lit.
- Reception can see the building's technical status without calling maintenance.
This record describes a reference architecture. Measured performance figures are published only for completed sites, with the client's agreement.
Describe the building. We will describe the infrastructure.
A study, a detailed cost breakdown discipline by discipline, and one point of contact from the first survey through to maintenance. We reply within two working days.
