From refrigeration system optimization and HVAC analysis to predictive control, CFD simulation, and GEG compliance.
Industrial refrigeration systems often lose 10–30% efficiency over the years—typically due to improper control settings, fouling, unsuitable setpoints, or suboptimal part-load operation.
Analysis and optimization of HVAC systems in accordance with ASR A3.6, with a focus on air quality, energy efficiency, and stable operation.
Predictive control of HVAC systems using weather data, operating profiles, and intelligent delta-T strategies.
Computational Fluid Dynamics for analyzing airflow, temperature distribution, and flow uniformity.
GEG §71a-compliant energy and system monitoring for non-residential buildings over 290 kW: capturing data, analyzing it, identifying efficiency losses, and implementing cost-effective retrofits.
GEG §71a: Building automation, energy monitoring & system performance — implemented cost-effectively
Many buildings have a BMS or “monitoring” system. However, §71a GEG does not refer to just any visualization, but to a clearly defined minimum functionality: continuous monitoring, logging, and analysis, identifying efficiency losses, and actively informing responsible parties — including a standard, freely configurable interface for manufacturer-independent evaluation.
Who does §71a apply to?
§71a applies to non-residential buildings where the rated output of the heating system (or combined heating and ventilation system) exceeds 290 kW — as well as to air conditioning systems or combined air conditioning and ventilation systems exceeding 290 kW.
What does §71a require from a technical perspective?
Important: §71a is more than “traditional BMS”
In existing buildings, the focus is functionally on digital energy monitoring technology. Existing BACS/BMS systems can meet the requirements if main energy carriers are recorded automatically and continuously.

Typical savings levers
A compact overview of our services in the areas of GEG compliance, refrigeration, HVAC, smart building, BMS, and CFD.
GEG & compliance
Refrigeration systems (industry & commercial)
HVAC / MEP / air quality
Smart Building / BMS / data
CFD simulation
Results-oriented
In projects, significant savings have been achieved through operational analysis, control optimization, and targeted measures — reaching up to several hundred thousand euros per year.
Hospitals and data centers are among the most technically demanding building types: high operating hours, critical comfort and hygiene requirements, redundancy concepts, and a significant impact of HVAC and refrigeration systems on energy consumption and availability.
We support operators and facility teams holistically — from technical assessment and optimization to monitoring and operational stabilization:
Hospitals & healthcare (hygienically safe & operationally reliable)
Data centers (availability + energy performance)
Office, commercial, retail & residential (comfort-oriented & cost-effective)
Optional: CFD simulation (when air distribution is critical)
CFD-based analyses to prevent hot/cold spots, short-circuit airflow, and drafts — especially relevant in sensitive zones (hospitals, labs, high-occupancy areas)
In addition to consulting and optimization, we also provide service, repair, and maintenance for refrigeration systems — with a focus on operational reliability, efficiency, and rapid fault resolution.
Our approach goes beyond simply “replacing parts” — we identify root causes and restore systems to stable and efficient operation.
Our areas of application
Scope of services
An effective ISO 50001 energy management system is more than documentation: it combines metering concepts, data quality, energy performance indicators (EnPIs), and technical measures into a continuous improvement process (PDCA). We support companies in developing and optimizing ISO 50001-compliant structures while directly integrating energy management with the technical reality of building systems such as HVAC, cooling, heating, and BMS/GLT infrastructure. This enables measurable, transparent, and audit-ready optimization processes.
