Why it is necessary to measure energy consumption?
Lack of information – in order to reduce unnecessary consumption, it should first be determined which consumers will consume resources when they should not.
Storage of information – in order to have a more in-depth analysis of energy consumption, at least hourly consumption information is needed, preferably even more accurate.
Excessive consumption – if only monthly data on energy consumption are available, which do not arrive until the beginning of the following month, the detection of leaks and over-consumption is a retrospective stating of the facts.
Alarms – the system can be configured to send alarms in case of emergency events.
Data collection – manual data collection is troublesome and insufficiently detailed for in-depth analysis.
Invoicing – the measurement system allows the staff managing the building to deal with substantive issues instead of picking up exhibitions and rewriting them into a table.
As a rule of thumb, one meter should be installed for a minimum of € 10,000 per annual energy cost step (for example, at least 10 meters per € 100,000 annual electricity consumption should be installed), preferably for every € 5,000 cost step.
In this way, it is possible to separate consumption for analysis and identify the causes of anomalies.
The solution is a remotely readable metering system, through which data from meters is collected, transmitted encrypted to the cloud server and stored.
The basic functionality of the remote reading service includes a monthly tabular report with readings and consumption and access to a remote reading system where the sample can be monitored and retrieved in real time.
Average investments and payback periods of solutions

Example detected shortages
Improper operation of ventilation and cooling equipment detected, resulting in an annual cost of several thousand euros. The controller had to be replaced because the device did not follow the set control logic.
Metal processing company
A relatively underused part of the building, which was continuously electrically heated, was identified, generating an annual cost ofseveral thousand euros, which could be reduced several times with optimal management.
A design error was detected that prevented the required indoor climate parameters from being achieved indoors. Without a measurement system, diagnosing the error would have proved very difficult
Numerous anomalies were identified in the management and operation of technical systems, 27% savings in annual heat consumption and 10% savings in annual electricity consumption were achieved.
Numerous anomalies were identified in the management and operation of technical systems, 3% savings in annual heat consumption and 14% savings in annual electricity consumption were achieved.
Numerous anomalies were identified in the management and operation of technical systems, 3% savings in annual heat consumption and 8% savings in annual electricity consumption were achieved..
A leak was identified in the water supply system, costing almost € 2,000 a year.
The consumption of a large complex was separated, it turned out that the logic previously used for input pricing of products (based on square meters) was very unfair in terms of energy consumption (resource use based on square meters differed several times).
European Union directive for remote reading
According to Article 9c of European Union Directive (EU) 2018/2002, meters and heat cost allocators to be installed in apartment buildings or multi-purpose buildings after 25 October 2020 must be remotely readable and by 1 January 2027, previously installed meters must also be switched to remote reading or replaced with a remote reading meter.
