Tenergis optimises the existing heat supply of large buildings with more than 4,000 m² of heated floor area – using intelligent control, dynamic heating curves and continuous monitoring. No complete heating-system replacement is required.
Many buildings are operated using rigid heating curves. Outdoor temperature, building inertia, actual heat demand and the time of day are often only taken into account to a limited extent.
Tenergis adds intelligent, internet-connected control to the existing system. It regulates temperature and flow according to demand, makes better use of heat already present in the building and reduces unnecessary peaks.
The system combines building behaviour, system hydraulics and weather data to continuously optimise the heat supplied.
The system determines how quickly the building cools at different outdoor temperatures. This allows the heat supply to be modulated for short periods without changing thermal comfort.
Flow velocity, recirculation and heating curves are dynamically controlled according to outdoor temperature, time of day and day of the week.
In addition to its own outdoor sensor, the system takes data from the nearest weather station and the forecast temperature trend for the next few hours into account.
The infrastructure uses equipment from renowned manufacturers including GRUNDFOS and Tech Sterowniki. Internet connectivity provides continuous access to operating parameters and enables ongoing remote adjustments.
Continuous monitoring
Direct visibility of operating parameters and efficiency.
Real-time optimisation
Settings can be adjusted continuously.
Easy to maintain
Clear infrastructure and defined warranty conditions.
The following illustrations come directly from the supplied technical system description and show the hydraulic principle as well as the pump and control technology used.
The guaranteed minimum saving is specified in the contract. The key condition is that the building’s essential usage and heat-consumption conditions remain unchanged compared with the time the offer was prepared.
Discuss the guarantee for your projectAccording to the system description: removal of the installed infrastructure, restoration of the pre-modernisation condition and reimbursement of the installation costs incurred.
Consumption is weather-adjusted and normalised using degree days. In Germany, meteorological data from the German Weather Service (DWD) are used for this purpose.
Transparent, collaborative and measurable – with a clearly defined project process.

Our focus is on companies and institutions with buildings of more than 4,000 m² of heated floor area, where high heating costs create correspondingly high savings potential.
Tenergis and the SAE team have completed numerous energy-efficiency and heat-management projects in Poland. Below are selected references from current Tenergis materials and published case studies.
Gdańsk Airport is explicitly listed in the current SAE materials as a reference in the public-infrastructure sector – a particularly strong example of the system being used in large, technically demanding buildings.
For this 4,220 m² multi-family building, the SAE materials report a 28.7% year-on-year reduction in energy consumption. Degree days are used to ensure an objective comparison.
A selection of locations and customers named in the current SAE materials.
* Project results depend on the individual property. Specific savings figures for individual references are published only when they are documented and approved for publication.
Savings are assessed using actual, weather-adjusted heat consumption and evaluated after 12 months.
Clear baseline, transparent evaluation and a contractual minimum guarantee.
Typical payback of up to three years for buildings over 4,000 m².
The control system responds to the building’s actual behaviour and monitors critical rooms.
The system is continuously monitored and adjusted for the best possible efficiency.
Questions about your building? In an initial savings-potential discussion, we clarify the starting point and the data we need.
No. The SAE system is designed to optimise the existing heat supply. It supplements the current infrastructure with control, pump, measurement and automation technology.
At least 11% of the heat energy consumed per year, provided the usage and comparison conditions defined in the contract are met.
Heat consumption before and after the modernisation is compared on a weather-adjusted basis, using degree days and official meteorological data, among other factors.
After the contract is signed and the down payment has been made, installation is planned within up to 8 weeks. Calibration of the building behaviour then typically takes 2–3 weeks.
24 months. According to the system description, maintaining the warranty requires a paid annual warranty inspection by the end of the 13th month after installation; the cost is specified for each property in the offer.
For an initial assessment we need only a few details: building area, a current heat or fuel bill, photos of the heating system and some information about how the building is used.
