Cooling energy intelligence
A solution for determining cooling energy consumption
SOLTS enables detailed cooling-energy measurement in existing hydronic cooling systems with minimal physical intervention.

The problem
Cooling systems are complex. Energy data shouldn't be.
In many multi-tenant commercial buildings, detailed cooling-energy accounting is difficult. The traditional approach often means:
Traditional approach
SOLTS approach
SOLTS does not always fully replace traditional meters. Suitability depends on the hydraulic configuration of the specific building.
The solution
Measure more. Install less.
SOLTS combines externally mounted measurements, existing building data and its own calculation methodology into a single environment.
Flow
Non-invasive, clamp-on flow measurement on existing pipework.
Temperature
Surface temperature data on supply and return lines.
Existing data
Integration of BMS, SCADA, meter and sensor data already on site.
SOLTS Engine
A calculation and segmentation model adapted to the building's hydraulics.
How it works
Five steps from pipework to insight
- 01
Map
SOLTS assesses the hydraulic structure of the building's cooling system.
- 02
Connect
Available BMS/SCADA and other data sources are identified.
- 03
Measure
The required non-invasive temperature and flow sensors are installed.
- 04
Calculate
The SOLTS methodology combines measurements and available data in one calculation model.
- 05
Analyse
The client receives detailed cooling-energy data by tenant, zone or other segment.

Segmented measurement
One flow measurement. Multiple insights.
In certain hydraulic configurations, a single flow data source can be used to calculate several consecutive consumption segments, where the flow is physically attributable to those segments.

Innovation
The innovation is in the system — not in a single sensor.
SOLTS is not the invention of one new sensor. The novelty is created by the combination of methodology, data and software.
- Physical system
- Measurements
- Data integration
- Hydraulic model
- Segmentation
- Calculation engine
- Energy insights
The technological core of SOLTS is the ability to build a measurement and calculation model matched to a specific building's hydraulics, with minimal additional measurement infrastructure.
Technology readiness
From prototype to validated technology
SOLTS is currently at TRL 5. Technology elements have been tested in a real operating environment, including surface temperature sensors on cooling supply and return pipes.

TRL 7
Target
At this development stage, full validation of the cooling-energy calculation is not yet complete, because flow measurements are not yet integrated. Next stage: flow integration → segmented calculation → real-world validation.
Real-world pilot
From development to real buildings
Installation and testing of the SOLTS solution is planned at Zunda Towers in Riga.

Market context
Why cooling energy measurement matters
EU energy-efficiency regulation is evolving toward more detailed cooling-energy measurement requirements where technically feasible and economically justified.
Sustainability
Better data. Better cooling efficiency.
No specific CO₂ or energy-saving figures are claimed — validated data is not yet available.
