Already Have an Energy Audit, BMS or Energy Monitoring?
That's not a problem — SWP is designed to complement them.
An energy audit or energy survey can identify opportunities and recommend improvements.
A Building Management System (BMS) controls and manages building services.
Half-hourly data, smart metering and cloud-based energy monitoring can show how electricity consumption changes over time.
SWP asks a different question:
Why is that electricity being consumed?
We use temporary high-resolution electrical load profiling, onsite engineering investigation and overnight observation to examine how individual areas and systems are actually behaving.
So if your hotel already has an energy audit, energy survey, BMS, smart metering or permanent energy monitoring, SWP doesn't necessarily duplicate it. We investigate the electrical behaviour behind the data.

Why Measuring Actual Operation Matters
Efficient equipment and sophisticated controls are valuable — but the important question is how the building is actually operating today.
Maximum demand isn't normal demand.
Pumps, fans and other building-services plant are commonly selected to meet maximum expected demand, with an additional design margin to ensure adequate capacity under the most demanding conditions.
That's sensible engineering. But a hotel does not operate at maximum demand all of the time.
Variable-speed drives (VSDs), Building Management Systems (BMS) and other controls can allow plant output to respond as demand changes. The question is not simply whether those systems are installed — it is whether the plant is actually responding to demand as intended.
Working doesn't necessarily mean optimised.
Plant can continue doing its job while consuming more electricity than necessary. Controls can be overridden, equipment may remain in manual operation, operating schedules can change, or a VSD may no longer be varying speed as intended.
None of this necessarily creates an obvious fault. Guests may still have hot water, rooms remain comfortable and the hotel continues to operate normally. The difference may only become apparent when actual electrical behaviour is measured.
What if monitoring inherits an inefficient baseline?
Half-hourly data and cloud-based energy monitoring can provide valuable visibility into how a hotel consumes electricity and how that consumption changes over time.
But was the starting baseline efficient in the first place?
If unnecessary consumption already exists when monitoring begins, it can form part of the building's established operating profile.
SWP therefore combines measurement with onsite engineering investigation. We don't simply ask whether consumption is unusual compared with the past. We investigate whether the electricity being consumed is actually necessary for the work the building needs to do.
LOOK → MEASURE → INVESTIGATE → RECOMMEND
LOOK — What equipment, controls and systems are actually installed?
MEASURE — How much electricity are individual areas and systems actually consuming through real operating cycles?
INVESTIGATE — Why are unexpected or suspicious loads behaving as they are?
RECOMMEND — What, if anything, is worth changing?
No assumptions. No predetermined solution. The evidence comes first.
We don't ask whether your hotel is using a normal amount of electricity.
We ask whether the electricity it is using is necessary.
