Lerta Energy Intelligence is a hardware and IT platform that integrates all the measuring and control equipment in buildings, factories, warehouses, etc. It allows for accurate measurements of energy consumption, intelligent control of devices, and thus reducing the expenditure on electricity and heating by up to 40%. Additionally, it minimises the carbon footprint by reducing CO2 emissions. And all this without any investment.
More than an energy management system.
• Consumption measurement
A system of remote measuring devices in combination with intelligent sensors monitors energy consumption and sends data to the cloud or to a dedicated server.
• Learning system
Algorithms using artificial intelligence predict and optimise consumption taking into account many factors, such as weather forecast, prices, thermal profile of rooms and the number of people currently using them.
• Intelligent control
The control application allows you to control devices such as air conditioners, heaters, production machines, etc. from your browser or smartphone.

Polsonic - energy management in an office building - case study
The Lerta Energy Intelligence system automatically controls the heating in the office building, reducing heat demand and optimizing heat consumption, and reads data from electricity meters that allows each tenant to be billed according to actual consumption and to catch anomalies in electricity management.
The biggest challenge for us was the high energy consumption of the existing solution, rigid heating hours of the building causing penalties for exceeding the contracted capacity in the morning and time-consuming, "manual" control of meters.
We have been cooperating with Lerta since February 2019, when it implemented the Lerta Energy Intelligence system in the Polsonic office building. As part of the project, measurement and control devices were installed, connected to the application for data management and analysis. Total heat energy savings are 22. 5% compared to the period before the system was implemented.

Cheap electricity from a virtual power plant
The connection with our virtual power plant provides, among other things, the possibility of concluding PPAs, under which you can contract cheap green electricity, independent of price increases, for many years.
• Investment model:
- the customer pay the costs of devices, installation and configuration and pays a low subscription fee
- no long-term commitments,
- quick return on investment,
- potentially high ROI.
• Subscription model:
- You DO NOT pay the equipment and maintenance costs,
- You pay a slightly higher subscription fee,
- no need to involve your own resources,
- positive investment balance from the very first day,
- contract for 5 years.
• Support instruments:
- obtaining a grant from the National Fund for Environmental Protection and Water Management,
- getting Jessica loans,
- obtaining commercial financing (loans, leasing),
- applying for, obtaining and selling white certificates.

A new day is coming up
Preparation for the first guests
The first people start work at 6. 00 a.m. The system issues an order to increase the temperature in production and storage halls to 20oC. Gradual heating of the rooms saves energy and flatten the peak of energy demand. This avoids possible penalties for exceeding the contracted capacity.
Preparing the office
At 8. 00 a. m. office and customer service employees start their working day. The system increases the temperature to 22oC in the marketing and accounting department and to 21oC in the customer service department. The management likes the heat, so the temperature here is increased to 23oC.
6:00 a.m. - 4:00 p.m.
A working day
The system maintains the desired temperature in each room by controlling radiators and air conditioners fully automatically. Door and window opening sensors prevent energy losses while ventilating rooms by cutting off the heating during this time.
The system knows that after the work is finished, the cleaning of the rooms takes place, which lasts until 18. 00. Only now it disconnects all energy-intensive devices such as air conditioners and lowers the room temperature in such a way that the energy consumption to maintain heating and to regulate the temperature on the next day is as low as possible.
6:00 p.m. - 8:00 p.m.
Motion sensors detected that the main accountant's room was not finished yet. The temperature in this room is maintained at all times when people are in it.
9:00 p.m. - 4:00 a.m.
The building is empty, the last offices are closing. AI lowers the temperature in the building to minimize the energy demand while nobody is there and to prepare for the morning heating.
9:00 p.m. - 4:00 a.m.
