GEG Verification for Industrial and Non-Residential Buildings

Zoning, DIN V 18599 calculation, user profiles and energy performance certificates for industrial building projects

INOPCO prepares energy performance verifications for industrial buildings, production buildings and non-residential buildings. The focus is on realistic zoning, robust building data, building services coordination and traceable calculation according to DIN V 18599.

Especially for industrial buildings, early integration into design and approval planning determines effort, verification reliability and structural feasibility. Production-related use, technical rooms, office areas, laboratories and utility areas must be clearly separated in the energy model.

Zoning of an industrial building for GEG verification

Direct Answer

GEG/GModG verification shows whether a non-residential building meets German building energy requirements. For industrial buildings, calculation is typically based on DIN V 18599 with zoning.

For whom?

For clients, operators, architects, building services planners and project teams working on new buildings, extensions or approval-relevant planning of industrial and non-residential buildings.

Result

Zoning model, building data, user profiles, building services boundary conditions, DIN V 18599 calculation, verification documentation and basis for energy performance certificate or approval documents.

Legal Basis and Verification Logic

current legal structure and non-residential building requirements combined

The former German Building Energy Act is now listed in current federal law as the German Building Modernization Act. For clients and search queries, the term GEG verification remains highly relevant. In substance, the verification concerns energy requirements for the building envelope, technical systems and annual primary energy demand.

For new non-residential buildings, annual primary energy demand must be limited in relation to a reference building. Non-residential buildings are calculated according to DIN V 18599. If areas differ significantly in use, technical equipment, internal loads or daylight supply, the building must be divided into zones.

  • Section 2: scope for heated or cooled buildings and technical systems
  • Section 18: total energy demand for new non-residential buildings
  • Section 21: calculation of annual primary energy demand according to DIN V 18599
  • Section 30: zone-based consideration of energy demand shares

Scope of GEG Verification

from planning coordination to verification documentation

Check Applicability

Classification of building type, use, conditioning, operating conditions, production relevance and approval-related verification requirements.

Zoning

Division into meaningful energy zones according to use, technical systems, internal loads, lighting, ventilation, temperature requirements and daylight.

Building Data

Recording of geometry, envelope areas, components, U-values, floor area references, window ratios, shading and energy-related properties.

User Profiles

Selection and technical adaptation of suitable user profiles for production-related ancillary areas, technical rooms, laboratories, offices, social rooms and circulation areas.

Building Services Coordination

Coordination of heating, cooling, ventilation, lighting, hot water, building automation, energy sources and project-specific primary energy factors.

Verification & Documentation

Calculation, plausibility check, result documentation and preparation for building permit application, energy performance certificate or project file.

Industrial Buildings Are Rarely Standard Cases

use, building services, process environment and building envelope must be assessed together

In industrial buildings, technical challenges often arise from combinations of production, technical rooms, storage, laboratories, offices, social areas and circulation spaces. Each of these uses may have different temperatures, operating hours, internal loads, ventilation requirements and lighting conditions.

GEG verification should therefore not be created only at the end of planning. It must be coordinated early with design, building services, building physics, fire protection, plant design and approval planning. This keeps the design controllable and avoids later corrections to the building envelope or technical systems.

GEG Verification Process

clear process for design planning, building permit and energy documentation

1. Clarify basis

Building type, use, planning status, approval objective, building services concept and existing documents are classified.

2. Build zoning model

The building is divided into suitable zones according to use, building services, internal loads, lighting and daylight supply.

3. Record building data

Geometry, envelope areas, components, window ratios, U-values, thermal bridges and energy-related properties are recorded.

4. Coordinate building services

Heating, cooling, ventilation, lighting, hot water, energy sources and building automation are coordinated with specialist planning.

5. Perform calculation

Real building and reference building are calculated according to DIN V 18599 and results are checked for plausibility.

6. Document verification

The results are prepared in a traceable way for approval documents, energy performance certificate or project documentation.

What You Receive

Frequently Asked Questions on GEG Verification

answers for clients, operators, architects and building services planners
Does GEG verification also apply to industrial buildings?
Yes, if the building is heated or cooled according to its intended purpose and no exemption applies. Energy use for production processes itself is not subject to the law; however, energy requirements for buildings and building-related technical systems remain relevant.
Why should verification start early?
Because zoning, building envelope, building services concept and user profiles directly influence the result. If these points are checked too late, necessary changes to design, façade or technical systems can become costly.
What is the difference between GEG verification and an energy performance certificate?
GEG/GModG verification serves planning and legal verification. The energy performance certificate documents the energy quality of a building according to legal requirements. For new buildings, the demand certificate is usually derived from the calculation.
Can INOPCO coordinate with building services and building design?
Yes. INOPCO supports energy-related coordination with architecture, building services, building physics, approval planning and operator requirements. This is especially important for industrial buildings with complex uses and plant environments.
