Offices and mixed use

Find problems before your tenants find them.

Tenant complaints are the most expensive way to learn that a floor is overcooling, a fan has not proven or a conference room is under-ventilated. Smart Tenants watches every air handler, terminal unit and meter continuously, ranks what matters, and keeps unresolved conditions visible across shifts and contractors. Asset managers see reliable operations and energy per square foot; engineers get the likely cause before the site visit.

Who it helps

How do we identify building problems before tenants escalate them?

For the owner and asset manager

  • Fewer complaints and faster resolution, which is what renewals are made of.
  • Energy and cost per square foot, with potential waste flagged for investigation.
  • Carbon from metered energy for reporting to investors and lenders.
  • A consistent picture across the portfolio, whoever operates each building.

For the chief engineer and property team

  • A ranked morning list instead of a wall of alarms.
  • Overcooling, fans at maximum, static pressure off target and valves pinned open, each with the likely cause.
  • After-hours run time and schedule overrides made visible.
  • Diagnosis before the site visit, so the right person goes with the right part.

For tenants

  • Comfortable floors because faults are found before they are felt.
  • Ventilation checked against CO2 and occupancy in conference rooms and open plans.
  • Fewer disruptive emergency repairs during business hours.

A morning briefing

What the engineering team sees first.

Every condition is ranked by severity, how long it has been going on and whether it has happened before, with the first check written out. The team starts at the top.

What Smart Tenants watches

  • Air handlers and rooftop units by floor and zone
  • Terminal units: airflow against setpoint, damper and reheat behaviour, CO2 where instrumented
  • Economizers and outside air dampers
  • Central plant where present
  • Main and tenant meters, with cost per square foot

Morning briefing

Example office tower, 6:00 AM

Example
Building status: not normal. Two conditions need attention this morning.
  1. 1
    AHU-3 Floors 10 to 14critical

    Discharge air well below setpoint with the cooling valve pinned open. Overcooling the north side.

    Do firstCheck the valve actuator and the control loop before the floors fill.

    What the data shows

    • Discharge air 48.7 °F against a 55 °F setpoint.
    • Cooling valve at 100 for the last 6 hours.
    • Return air cooler than yesterday at the same hour.

    What is inferred

    The valve is driving the deviation rather than responding to it: a control-loop or actuator fault.

    What to check

    Check the valve actuator and the control loop before the floors fill.

  2. 2
    VAV 12-07high

    CO2 above the warning level while occupied yesterday. Damper at minimum.

    Do nextCheck the damper and the minimum airflow setpoint.

    What the data shows

    • CO2 above the warning level from 10:00 to 16:00 yesterday while the zone was occupied.
    • Damper at its minimum position throughout.

    What is inferred

    Occupied, under-ventilated: a damper or minimum airflow setting problem, not a sensor fault, because CO2 fell overnight.

    What to check

    Confirm the damper moves off minimum and review the minimum airflow setpoint for the room.

  3. 3
    RTU-2watch

    Outside air at minimum with cool outside air while the cooling coil works.

    Do nextInspect the economizer damper and its control.

    What the data shows

    • Outside air damper at minimum.
    • Outside air cooler than return air for the last 5 hours.
    • Cooling coil valve open.

    What is inferred

    Free cooling is available and not being used: the economizer is disabled or its damper is stuck.

    What to check

    Confirm the economizer is enabled and that the damper actually travels when commanded.

Comfort, energy and carbon

Office buildings waste energy quietly: heating and cooling at the same time, economizers that never open, and systems that start hours before anyone arrives.

  • Ventilation quality by zone against ASHRAE 62.1 guidance, correlated with occupancy so an empty room is not a complaint.
  • Economizer use: free cooling taken when outside air allows, and under-ventilation while occupied flagged as an air quality problem.
  • Optimal start and stop: the building’s thermal response learned, so pre-conditioning starts as late as it safely can and the building coasts at the end of the day. It runs in monitor mode first, writes only when you enable it, and never outside the limits you set.
  • Carbon from metered energy with grid factors by region.
  • Measurement and verification: whole-building savings tracked against a weather-normalised baseline, the standard way to show a lender or a board what an operational change was worth.
