Building types

Every building has its own load curve

An office empties in the evening, a warehouse works two shifts, a shop turns the lights on an hour before opening. So the waste, the equipment to connect and the implementation time differ.

Office buildings and business centres

Demand is flat during the day and should fall to 30–40% of peak at night. If the building draws more than half of its daytime maximum at night, ventilation or lighting is not switching off somewhere.

Non-working hours: this is where waste usually hides

Where energy is usually lost

  • Climate on an old schedule

    Air conditioning starts at 5 a.m. and runs until 11 p.m., while tenants arrive by 9.

  • Weekends like weekdays

    Supply air units run on the weekday schedule on Saturday and Sunday.

  • Heating and cooling at once

    In shoulder seasons fan coils cool air that radiators are heating.

  • Unmonitored server room

    Precision air conditioners hold 18 °C where the equipment is fine at 24 °C.

What we connect

  • Main switchboard incomer meters
  • Floor panels: lighting and sockets
  • Chiller, supply air units, heat substation
  • HVAC controllers over BACnet/IP or Modbus
  • Server room: UPS and air conditioning

How long implementation takes

  1. Survey and metering point list1 week
  2. Gateway installation and device connection2–3 weeks
  3. System mapping and baseline2 weeks
  4. First anomalies and report1 week
