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.
A typical working day
Working hours 08:00–20:00
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
- Survey and metering point list1 week
- Gateway installation and device connection2–3 weeks
- System mapping and baseline2 weeks
- First anomalies and report1 week
Total6–7 weeks

Two shifts from 07:00 to 21:00. At night emergency lighting, dock heating and forklift charging stay on, so night-time load is higher than in an office.
A typical working day
Working hours 07:00–21:00
Non-working hours: this is where waste usually hides
Where energy is usually lost
Lights in empty aisles
Lighting is on in every racking zone, including those where no shift is working.
Air curtains at closed doors
Curtains run all day although dock doors open only a few times an hour.
Charging at peak hours
Forklifts go on charge right after the shift, together with the demand peak.
Ventilation on the weekday schedule
Extract fans run at weekends exactly as on working days.
What we connect
- Incomer meters and zone lighting panels
- Forklift charging stations
- Air curtains and warm-air heating
- Heat meter of the substation or boiler house
How long implementation takes
- Survey and metering point list1 week
- Gateway installation and device connection1–2 weeks
- Zone mapping and baseline2 weeks

Estimate savings for this kind of buildingShops and retail premises
Demand rises 1–2 hours before opening and holds until closing. Refrigeration runs around the clock and sets a high night-time minimum.
A typical working day
Working hours 09:00–22:00
Non-working hours: this is where waste usually hides
Where energy is usually lost
Climate starts too early
Air conditioners start at 6 a.m. although the shop opens at 9.
Signs and windows at night
Outdoor signage and window lighting stay on until morning.
Doors and air curtains
Entrances stand open while air curtains run at full power.
Unmonitored refrigeration
Display cases without night blinds use more than they need, and failures show up only as written-off stock.
What we connect
- Incomer meter and sales floor panel
- Refrigeration units and racks
- Air conditioners and air curtains
- Outdoor signage and window lighting
How long implementation takes
- Survey of the first shop1 week
- Connection and a template for the chain2–3 weeks
- Baseline and first anomalies2 weeks
- Each further shop from the template1–2 weeks
