Daily meter pattern
Show high, low and abnormal days against expected opening hours, such as Monday to Friday 08:00–18:00.
Baseline reporting
Energy optimisation should be measured against building use, weather and BMS operation.
For offices, campuses and multi-tenant buildings, the strongest reports combine meter readings, degree-day/weather context, occupancy hours and BMS evidence such as schedules, setpoints, valve positions, fan status and alarms.
Degree-day context
Compare heating or cooling demand with weather so a high-use day can be separated from a poor-control day.
Time-clock evidence
Highlight plant enabled two hours too early, late shutdowns or holiday schedules that do not match the building.
Comfort and calibration
Record rooms reported too hot or cold, then check sensors, setpoints and control outputs before changing the strategy.
Savings should be treated as opportunities until verified with reliable meter, trend and site evidence.
Need more than an energy report?
Bridge the gap between the energy consultant and the BMS maintainer.
Where a report identifies high usage but no one is instructed to change the controls, The BEMS Guy can review the BMS, monitor a test area, prepare evidence and coordinate the software changes that should be discussed with the existing BMS provider.
Energy & alarm optimisation
Energy‑focused control changes, alarm clean‑up and metering reviews to cut waste, reduce noise and surface the right data.
The goal is to turn your existing building automation into the most energy‑efficient version it can be – using sensible strategies, sustainability‑led setpoints and clear reporting. I work across monitoring, metering and controls side by side so you can see where energy is going, where comfort is at risk and which changes will give you the best return.
What's included
- Review of existing control strategies and schedules.
- Adjustments to setpoints, deadbands and schedules.
- Rationalisation of alarm lists and priorities.
- Clear before/after notes for your records.
Evidence-led optimisation
- Use trends, meter data, schedules and occupancy information where available.
- Check comfort, safety limits and plant capability before tightening setpoints or run times.
- Separate quick wins from longer-term projects so budgets can be planned sensibly.
Energy improvements should be verified over time. Savings cannot be guaranteed without reliable baseline data and agreement on how performance will be measured.
LoRaWAN wireless energy and occupancy evidence
Where the existing BMS does not have enough data, LoRaWAN sensors can add lower-disruption monitoring for temperature, humidity, CO₂, occupancy, plant status and metering inputs. This can help prove which areas are wasting energy and which changes should be made first.
- Less new wiring compared with hardwired survey sensors.
- Better evidence for room-by-room comfort and plant runtime checks.
- Useful for monthly reports and a 12-month yearly improvement roadmap.
Useful evidence to collect
- Meter readings or half-hourly data where available.
- Occupancy times, comfort complaints and known problem zones.
- Trend logs for temperatures, valve positions, dampers, fans and plant enables.
