Energy inspection in accordance with GEG: optimizing air-conditioning & ventilation systems for efficiency
Recognizing potential and sustainably reducing energy costs
Reducing costs with the Building Energy Act
Rising energy costs, statutory operator obligations and growing sustainability requirements pose major challenges for the operators of air-conditioning and ventilation systems.
The energy inspection in accordance with the Building Energy Act (GEG § 74) is more than just an obligation: if implemented correctly, it becomes an effective lever for efficiency, cost reduction and the future-proofing of your system.
With the energy inspection from Weiss Klimatechnik Service, you can turn this requirement into real added value – technically sound, practical and with clear recommendations for action.
Meeting statutory requirements:
Operators of ventilation and air-conditioning systems are obliged to have their systems regularly inspected for energy:
- an inspection obligation under GEG §74 has been in place since 01.01.2024 for systems in operation for ten years or more
- Obligations to provide evidence to the authorities and owners
- Increasing requirements in energy efficiency and CO₂ reduction
High energy and operating costs
- Air-conditioning and ventilation systems are among the largest consumers of energy in buildings
- Outdated components, inefficient operating modes or insufficient control cause unnecessary costs
- Much potential for savings remains untapped during ongoing operation
Creating investment security
- Uncertainty about the profitability of modernization measures
- Lack of transparency regarding payback periods
- Lack of clarity regarding possible funding programs
Comparison of operating and investment costs
Experience shows: Small investments – huge impact. Over the lifetime of a system, the investment costs usually account for a mere fraction of the overall operating costs.
Often, it is not necessary to renew the entire system. The overhaul of individual components for energy efficiency already leads to considerable savings.
Typical savings potential from the field:
Cleanroom production
- Renewal of fans
- Retrofitting for energy-efficient operating modes
- Annual cost savings: approx. €35,000
Medical ventilation systems
- Renewal of fans
- Optimization of heat recovery
- Annual cost savings: approx. € 20,000
Server room cooling / data centers
- Replacement of fans
- Load-dependent control
- Annual cost savings: approx. € 15,000
