Sub-metering and fair cost allocation for three apartment buildings

The manager of a residential portfolio split energy costs at a flat rate, regardless of each building’s actual consumption. There was no central overview and no basis for fair cost allocation. The solution had to be installed in occupied apartment buildings without restricting residents, and it has to grow with the manager.

Starting point

We understand the segment's challenges

Where costs and risks really arise in this environment, and why you cannot see them without metering.

01

Flat-rate allocation without metering

Without sub-metering, costs are split evenly, regardless of the actual consumption of each building or unit.

02

No central overview

The manager runs several buildings with no way to compare their consumption or track trends over time.

03

Installation without disrupting operation

In apartment buildings, metering has to be installed without restricting residents and in line with standards.

04

Room to grow

The system has to be scalable: electricity today, heat, water or another building tomorrow.

Project scope

What we deployed on the project

  • 7 metering points in 3 separate apartment buildings
  • 12 devices installed
  • Electricity meters with Modbus RTU communication, digital reading
  • Integration into the existing sub-distribution boards without major changes
  • Delivered in line with STN 33 2000, with inspection and functional testing
From the project: fitting electricity meters into sub-distribution boards

Real-time data

For the first time, the manager has a real overview of consumption by building

Metering installed without disrupting the buildings’ operation

A scalable system, easily extended to further buildings or utilities

The platform enables forecasting and comparing consumption over time

Concrete benefits · real findings

What the system delivered in practice

01

Fair cost allocation instead of a flat rate

Sub-metering gave the manager real consumption values by building, the basis for allocating costs according to actual use, not at a flat rate.

02

No disruption to the apartment buildings

We integrated the metering into the existing sub-distribution boards without restricting residents. The platform is ready to scale to further buildings and utilities: heat, water, gas.

Your challenges · our answers

What it means for an apartment building manager

Flat-rate allocation with no data on actual consumption

Sub-metering → fair cost allocation based on real values

No central overview across the buildings

A central dashboard, the consumption of all buildings in one place

The installation must not restrict residents

Integration into existing switchboards, no disruption to operation

The system has to grow with the manager

A scalable platform, further buildings and utilities at any time

Why Nidex Technology

Three reasons, each proven in practice

01

End-to-end responsibility

From design, hardware supply and installation to data integration, inspections and support. One supplier, one point of responsibility.

02

Technical precision and standards

We design in line with the Slovak standards STN 33 2000 and STN EN 61439. We issue statutory inspection and test reports (OPOS) with our own staff.

03

Based in Central Europe

We are based in Nitra, Slovakia, about two hours from Vienna and Budapest, and know the local legislation. Fast response, one team from design to service.

Proposed next steps

Three steps from a meeting to the first results

  1. 01

    Technical meeting

    A visit to the selected building. We define the scope, priority locations and constraints.

  2. 02

    Indicative quote

    An indicative price based on the agreed scope. Presentation of the technical design.

  3. 03

    Pilot project

    Deployment in one building. Verifying functionality, integration and training the operators.

Conclusion

Why it makes sense

The project gave the manager of a residential portfolio a real, central overview of each building’s consumption for the first time, the basis for fair cost allocation instead of a flat rate. The solution was installed without disrupting the apartment buildings and is ready to scale to further buildings and utilities. Metering is the first step; the platform makes it possible to build further on it.
