Equilibrium Predictive control for the buildings automation left behind.

A commercial office building fitted with Equilibrium A detailed five-storey glass office building is shown in perspective with a rooftop HVAC unit, entrance, visible floor plates, wireless room sensors, an on-site Equilibrium optimiser and the building's existing HVAC panel.

Predictive HVAC control for buildings without a BMS

Keep the building. Change the decision.

Wireless room sensing and local predictive control for commercial buildings with ordinary split and packaged HVAC, fitted around the equipment already there.

See every room in context.

Wireless room modules observe temperature, humidity, CO₂ and occupancy where the building is actually used. Schedules, weather and past behaviour explain where conditions are heading.

Think ahead instead of catching up.

The local optimiser tests possible actions against comfort, air quality, energy cost and equipment constraints before choosing a bounded instruction.

Work with the system already there.

The instruction passes through the supported connection to the existing HVAC panel. Equipment protections and the final control path remain authoritative.

Change the operation, not the equipment.

The aim is less avoidable runtime, steadier occupied spaces and clearer room-level visibility, with local operation at the centre of the architecture.

Intelligence without the infrastructure project.

Room modules observe temperature, humidity, CO₂ and occupancy where the building is actually used. The local optimiser combines those conditions with schedules, weather and past behaviour.

It looks ahead, chooses a bounded action and passes that instruction through the supported connection to the existing HVAC panel. Equipment protections and manual control remain authoritative.

Retrofit the intelligence.
Keep everything that still works.

Equilibrium is designed to add context and foresight—not refrigerant work, compressor rewiring, safety bypasses or a disruptive controls replacement.

Better operation should be measured, not promised.

The opportunity depends on the equipment, operating pattern and baseline. It should be established building by building, then verified in operation.

target reduction in HVAC energy use where the building is suitable

Built for the buildings in between.

Equilibrium is most useful where rooms change throughout the day and ordinary controls cannot see the difference: offices, schools, clinics, gyms, hospitality and other variable-use spaces.

It starts as a local retrofit system without depending on the cloud for core control. Planned BACnet/IP support keeps the architecture ready for wider building integration later.
