Olympic House — supervision and BMS for the IOC headquarters

HTML5 supervision and KNX automation for the headquarters of the International Olympic Committee in Lausanne — a building certified Minergie-P, LEED Platinum and SNBS Platinum.

The context

Olympic House, in Lausanne, is the headquarters of the International Olympic Committee. One of the most sustainable buildings in the world, it holds Minergie-P, LEED Platinum and SNBS Platinum certifications.

Such a building demands fine, reliable supervision of lighting, blinds and heating, zone by zone — with an interface usable by facility teams and an architecture able to carry the load without saturating the field buses.

HTML5 supervision & automation

Weble developed an HTML5 supervision interface (iPad / Android) driving the blinds, lighting and heating of every zone:

per-scene light dimming and occupancy-based constant-light regulation;
DALI fault reporting across nearly 7,000 luminaires;
calculation of the per-zone average heat demand, forwarded to the MCR supervision;
logging of every state change.

Distributed architecture & “Remote” driver

To keep the buses from overloading, the zones are partitioned and report to the central supervision through our “Remote” driver. The installation runs on 15 WBox S103 gateways and 2 redundant servers, ensuring continuity of service for the headquarters.

The benefit

Unified supervision: blinds, lighting and heating driven from a single HTML5 interface.
Comfort and savings: constant-light control and per-zone heat demand.
Proactive maintenance: nearly 7,000 DALI luminaires monitored, faults reported in real time.
High availability: two redundant servers for a strategic headquarters.

Modules & gateways used

WBox S103 — 15 gateways + 2 redundant servers.
KNX driver — lighting, blinds, heating.
Logic module — scenes, regulation, per-zone calculations.
Redundancy module — continuity of service.
Remote driver / remote access — uplink of partitioned zones and remote maintenance.
