Building automation
Building automation ensures that energy consumption in buildings is controlled in a targeted and efficient manner. This allows energy wastage to be recognised and avoided more quickly. Energy flows can be tracked using measuring devices. Control elements ensure that the energy technology functions automatically and proactively. The digital networking of energy systems enables perfectly harmonised and efficient control of installations.
The Building Energy Act (GEG) 2024 places these concepts for increasing energy efficiency more firmly in the focus of property owners. It obliges them to take measures in building automation in accordance with §71a. These measures can not only reduce energy consumption, but also increase the value of the property and make it even more attractive to tenants.
ecoGAAD
Efficient building automation for sustainable success
ecoGAAD supports you in sustainably reducing energy consumption in buildings by optimising building automation and reliably meeting legal requirements – in particular in accordance with GEG 2024 §71a. Our service applies to both new buildings and existing properties.
We use proven and established methods to check and document compliance with the applicable regulations. We also analyse your existing or planned building automation system and identify potential for optimisation. We carefully assess each proposed measure in terms of investment costs, energy-saving potential and profitability.
Our focus is on individualised and collaborative cooperation that is perfectly tailored to your requirements. Together, we create the basis for an energy-efficient and future-proof property.

Regulatory framework
With regard to building automation, the GEG 2024 requires building automation level B in accordance with DIN V 18599-11 for new non-residential buildings and the installation of digital energy monitoring technology for monitoring, logging and analysing energy efficiency in existing buildings. The obligation applies from 01.01.2025.
There are currently no legal requirements for residential buildings, but it is generally expected that these will follow in the next few years.

Our procedure
Initialisation
- Target definition
- Selection of the assessment methodology
- Determination of the cost groups to be assessed
Inventory analysis
- Evaluation of existing as-built documentation
- On-site inventory(s)
Research into unclear survey results - Evaluation of the results
Potential analysis
- Determination of optimisation measures and evaluation of costs, energy saving potential and amortisation
- Determination of costs through supplier enquiries if necessary
Modernisation variants
Presentation, evaluation and categorisation of individual measures in terms of costs, efficiency and increased comfort in three scenarios:
- statutory minimum standard
- cost-benefit orientation
- new-build orientated
Evaluation and definition of measures
- Comparison of the proposed measures
- Product suggestions if necessary
- Customer results workshop
Joint evaluation - Drawing up a catalogue of measures
- action plan
- final report
Catalogue of measures
We offer you customised solutions to optimise your building automation. Our aim is to meet legal requirements, increase energy efficiency and achieve an optimised payback period.
Here are some examples of our recommended measures:
Multi-stage pump control
|
|
|---|
|
Classification of measures:
Increasing energy efficiency |
|
Current status:
The heating circuit pumps work in two-point operation, which means that they only recognise the ‘On’ and ‘Off’ states. |
|
Proposed measure:
Conversion to multi-stage operation in which a partial load stage ‘Min’ is available in addition to ‘On’ and ‘Off’. This enables dynamic adjustment based on outdoor temperature thresholds or differential pressure. |
|
Advantages:
Energy savings by reducing heat consumption and electricity consumption, especially in the transitional periods; increased comfort thanks to demand-orientated heat supply without manual heating throttling. |
|
Estimated energy savings:
3 to 5 % per year (heat side) |
|
Amortisation period:
1 to 2 years |
Hydraulic balancing of the heat distribution
|
|
|---|
|
Classification of measures:
Normative obligation (GEG §60c) and energy efficiency improvement |
|
Current status:
No static or dynamic adjustment available. |
|
Proposed measure:
Introduction of dynamic (automatically continuous) equalisation between individual heat exchangers (method B or comparable) |
|
Advantages:
Energy saving through even heat distribution and reduction of heat consumption. Increased comfort thanks to automatic equalisation, which ensures even heat distribution without manual intervention. |
|
Estimated energy savings:
8 to 15 % per year (heat side) |
|
Amortisation period:
2 to 4 years |
|
Optimisation of the degree of building automation (according to GEG):
A |
