Measure at an actionable level
Define whole-site, submeter, tenant, room-group or equipment points without double counting and with a documented hierarchy.
KEYPLUS · Systems
Energy
Connect trustworthy utility measurement and selected controls to the spaces, schedules and operating decisions they support. KEYPLUS plans meters, collection, interfaces and energy intelligence as one verifiable chain rather than a dashboard without engineering context.
System at a glance
- Application: Whole-building, tenant, room-group, utility and major-equipment energy visibility and selected control.
- Components: Electricity, water or gas meters, current transformers, collectors, gateways and approved control interfaces.
- Integrated capability: Relate readings to spaces, equipment and available operating context, then route exceptions or approved actions.
- Operational value: Identify deviations earlier, prioritize investigation and evaluate operating changes against measured results.
Designed around a real operating responsibility
The metering hierarchy should follow the decisions the team needs to make. Measurement points, units, intervals and equipment relationships determine whether data can explain an issue. Revenue billing, engineering monitoring and optimization have different accuracy and governance requirements.
Core system capabilities
Collect and normalize trustworthy readings
Confirm units, scaling, timestamps, gaps, quality flags and source ownership before using values for reporting or analysis.
Detect and investigate operating deviations
Apply suitable thresholds and analytics to highlight changes, then consider schedules, weather, occupancy proxies and equipment conditions before assigning a cause.
Close approved control loops
Where control is in scope, send bounded settings through compatible interfaces, confirm device response and compare subsequent measurements while preserving local safety limits.
Components, interfaces and system boundary
Components may include electrical meters, water and gas meters, current transformers, multi-circuit monitors, collectors and gateways. Selected controls may include compatible HVAC interfaces, thermostats, relays, smart breakers or valves. Protection, essential services and specialist plant controls remain authoritative.
Where intelligence adds value
Energy intelligence can progress from descriptive reporting to anomaly detection, diagnostic assistance, forecasting and evaluated optimization recommendations. Advanced claims require suitable baselines and validation; an anomaly is not automatically a fault, and no fixed saving should be promised without evidence.
Follow one event through the system
A meter reports a persistent deviation
data quality and the metering relationship are checked
available schedule and space context are reviewed
the responsible engineer investigates
an approved operating change is applied where suitable
later readings are compared with the baseline and constraints.
Engineer and accept the system properly
Confirm electrical and mechanical installation, meter accuracy, CT ratios, units, time synchronization, intervals, network coverage and data gaps. Acceptance should verify representative readings against a trusted source, alarm behavior, command boundaries and measurement after change.
Where this system can be applied
Hotels, apartments, campuses, offices, retail portfolios, hospitals and mixed-use properties require different baselines and operating constraints. Billing or regulated measurement needs separate review.
System planning questions
Is a smart meter enough for automatic control?
No. Measurement and control require different hardware, interfaces and safeguards.
Can several utilities be included?
Compatible electricity, water and gas sources can be evaluated within a defined hierarchy.
Can the system guarantee savings?
No. Results depend on baseline, equipment, operations and verified changes.
Define the system around the required outcome
Share the site type, operating responsibility, approximate scale, existing equipment, required interfaces and the event or action the system must handle.
