Energy bills in a commercial facility are the sum of hundreds of processes, devices and zones — from HVAC and cold stores, through lighting, to compressors and production lines. A reading from the main meter shows the amount. It does not show where the loss occurs.
Percee® is an Energy Management and Optimization System (EMOS): a SaaS platform whose capabilities include continuous monitoring of electricity, heat, cooling, gas and compressed air. It collects measurement data at 15-minute resolution or finer, normalizes it and presents it in a single dashboard — whether you manage one building or a network of 1000+ sites.
One caveat up front: monitoring alone does not lower the bill. Measurement is a diagnostic layer — it shows where money is leaking, but changes nothing. It delivers real value only when treated as the first step toward control: the collected data becomes the basis for automated optimization and load control. That is exactly what separates a full EMOS from plain metering that stops at a chart. So read monitoring as an excellent foundation — not as the goal in itself.
Home energy monitors answer the question "how much do I use per month". In a commercial facility that question is useless. A facility manager needs to know why night-time consumption in hall B rose 18% versus the previous week — and which device is responsible.
Scale. A typical industrial facility has dozens of measurement circuits, several energy media and many billing zones. So Percee aggregates data from hundreds or thousands of measurement points at once.
Multi-utility. Electricity is only part of the cost. In office and retail buildings, district heat or natural gas can be significant. In production plants, process cooling and compressed air matter. So monitoring of energy and water media must cover all utilities — otherwise the cost analysis makes no sense.
Reaction time. The bill arrives a month later. Meanwhile an anomaly — a compressor running at full load over the weekend — generates cost for 48 hours before anyone notices. Real-time monitoring with alerts cuts that to minutes.
The platform collects data from meters at the main switchboard, sub-distribution boards and individual loads. Each measurement point can be assigned to a zone (hall, office, car park), a cost center or a technological process.
Recorded parameters include active and reactive power, power factor and the load profile at 15-minute intervals. This format aligns with utility requirements and allows precise allocation of demand and capacity charges.
Percee reads heat meters and cooling meters through any automation protocol, e.g. M-Bus or Modbus. Data on district heat, process steam or cooling from chillers flows into the same dashboard as electrical data.
In practice this means costs of HVAC can be set against outdoor temperature and the facility's operating schedule. The result: fast identification of periods when the heating or cooling installation runs without justification.
Gas meters (pulse or digital output) and flow sensors for technological media integrate with the platform without extra software and reach the same dashboard as electrical data. As a result, the cost analysis covers all utilities at once, not just electricity.
Each site reports data to the Percee cloud over an encrypted connection. An on-premise installation is of course also possible — useful, for instance, in regulated industries (for example defense or financial institutions). The central dashboard aggregates consumption, costs and energy KPIs across all sites. Filters let you compare buildings by region, facility type or production volume.
Access permissions are configured per site. A local facility manager sees their own site. The energy manager at headquarters sees them all.
In multi-tenant facilities — malls, logistics parks, office buildings — Percee assigns consumption to tenants or cost centers based on physical and virtual meters. Instead of splitting the bill by floor area, the owner issues a re-invoice based on real consumption: transparent and hard to dispute. The same data feeds the cost input to ERP, with no manual re-keying.
A consumption chart alone is not enough. The platform analyzes data in context — comparing the current load profile against the pattern for the day of week, season and the facility's operating schedule.
A sudden rise in power draw after hours, an unexpected chiller start at night, a base load persistently higher than usual — each of these triggers an alert. Notifications can reach designated people by SMS or email: the shift supervisor, the maintenance technician, the energy manager.
If two stores of similar area and opening hours differ in consumption by 35%, the platform shows it. Without a benchmark that difference is invisible — both sites sit within budget. But one of them may have a fault in the refrigeration installation or a poorly configured BMS. Benchmarking works on normalized indicators (kWh/m², kWh per production unit), so comparing facilities of different sizes immediately reveals which ones deviate from the rest of the portfolio.
Automatic summaries — daily, weekly and monthly — reach recipients' inboxes without logging in. They contain trends, deviations from the baseline profile and a ranking of sites by kWh/m² or kWh per production unit.
Monitoring data also meets the documentation requirements of ISO 50001 — the energy review, EnPI indicators and verification of improvement targets.
Percee does not require replacing meters, controllers or cabling. It connects to what is already installed in the facility.
In facilities without measurement infrastructure — e.g. older warehouses with a single main meter — we help with the selection and installation of sub-meters.
The platform architecture is the same for a single office building and for a restaurant chain. The scale of the rollout differs, not the functionality.
A retail chain with hundreds of points of sale. Each store has 3–8 measurement points (lighting, refrigeration, HVAC, back-of-house). The central dashboard shows a ranking of stores by consumption per square meter, deviations from the seasonal norm and sites with a suspected fault. The regional facility manager gets a weekly report listing sites that need intervention.
Five class-A warehouses, each with a refrigeration system, a sorting area and offices. Percee compares energy KPIs (kWh per pallet, kWh per m² of cold store) between warehouses and identifies which site deviates from the average. Monitoring data flows into the client's ERP via REST API — energy costs are allocated automatically to cost centers.
A plant with a dozen-plus production lines and its own transformer station. Monitoring covers consumption per line, electricity, gas, compressed air, steam and process cooling. The 15-minute data lets you align the production schedule with tariffs — no guessing, based on real load profiles.
After monitoring is up and running, the next step is energy reduction — automated control, setpoint correction and the elimination of waste based on the collected data.
