About 80% of the building costs are incurred during the utilisation phase

A building generates costs: With approximately 80% of all building costs incurred, the utilisation phase represents the largest share. In this connection, why is this the case and why are we talking about the importance of maintaining building automation systems and installations?

It is a fact that the main objectives in the operation of a building are the availability of the plants, economic profitability, efficient system operation, longevity, value retention and optimum energy efficiency. At this point, it is essential that we look at the role of a comprehensive service portfolio.

Viewing the costs in the life cycle of a building

In order to classify the topic, we take a look at the building life cycle. It serves to divide a building into different phases, which it “experiences " - from the development, planning and realisation to the utilisation phase and the deconstruction phase.

Let us take a closer look at the operation (utilisation phase). This phase covers the areas of facility management, maintenance, repair, refurbishment / modernisation and reutilisation.

Maintenance measures ensure the availability of the plants and predictable costs

GFR provides professional maintenance and support for the building automation systems of your premises in accordance with applicable laws, standards and guidelines as well as working group recommendations such as AMEV and VDMA 24186 - for rapid and competent solutions throughout the entire life cycle.

„Why should I have my plants serviced? It does run..."

Components and entire systems react more sensitively to signs of wear and tear and defects as a result of rapid technical development. Design and technology have developed enormously and are today, in times of digitalisation, changing more than ever.

Regular maintenance ensures safety, longevity and efficiency of your plants

Proper maintenance of building automation systems / measurement and control technology not only comprises checking the functionality of the system(s), it also prevents early wear and tear and enables an early detection of damages. Regular maintenance activities therefore reduce the susceptibility to faults and prevent failures or complications. Furthermore, maintenance is a matter of common sense and should also be carried out in regular intervals for the sake of the environment.

Benefit from the advantages of a professional maintenance:

  • Increased plant availability (reduction of downtimes and malfunctions)
  • Calculable costs
  • Promotion of the longevity of the plants
  • Maximum performance of automation systems
  • Value retention of the properties
  • Transparent documentation of service activities (traceability for the plant operator)
  • Maximum operational safety
  • Risk reduction
  • Adjustment of building functions and parameters to the needs of the operator
  • Improved profitability compared to systems that are not serviced
  • Professional workmanship by trained GFR service staff
  • Best availability due to on-site operation or remote access

Maintenance and Service – what is the difference?

Maintenance is the term used to describe all measures taken to preserve, identify, restore and improve machinery and equipment. These measures ensure that technical systems remain functional and safe. This is to prevent possible failures. According to DIN standard 31051, four basic maintenance measures are included: service, inspection, repair and improvement.

Service, on the other hand, is one of the preventive maintenance measures to delay the wear and tear of machines and plants as well as possible. Servicing guarantees trouble-free plant operation over a longer period of time.

GFR is your partner for comprehensive, competent plant support and maintenance

GFR - Gesellschaft für Regelungstechnik und Energieeinsparung mbH is a leading provider in the fields of building automation and building management and has been in international business for its customers since 1978. As a result of our extensive experience and know-how, we are in a position to take a comprehensive look at your plants and provide support from planning and installation to optimum assistance during operation.

We are there for you whenever you need us. Our experienced and trained service staff work with great diligence in accordance with AMEV and VDMA 24186 specifications for an optimum plant operation.

What areas does the maintenance of building automation systems cover?

The following list in accordance with AMEV and VDMA gives an initial overview of the measures and areas (VDMA 24186 describes the “Range of services for the maintenance of technical installations and equipment in buildings for measuring and control plants and building automation systems" in part 4).


  • Control cabinets (centralised and decentralised): clean, set, adjust and checking the functions,
  • Field level: Check, clean, measure, log or readjust sensors (e.g. measured value sensors/generators, measured value transducers, monitors, limiters). This also includes actuators, meters, decentral bus-capable modules and local override devices.
  • Room automation level: check, clean, measure and log room operating units, room controllers, room sensors, room actuators, check communication with superordinate system
  • Automation level: check, clean, replace, calibrate, adjust, secure and document controllers
  • Management level: check, clean, replace, read out and document operating station/operating unit (e.g. tablet PC, laptop, smart devices), input and output devices, displays and storage devices, internal and external programming unit and data interface units and data processing equipment/server station
  • Network: Check communication, test and clean network structure components (e.g. switches, routers, access points) and establish connections
  • Software: check, archive and save access rights, ensure IT security in accordance with VDMA 24774 and carry out backup of data and software
  • Check operating mode
  • Documentation and marking: Check maintenance-relevant documents (e.g. diagrams, manufacturer's specifications) and existing plant marking.

Remote maintenance and technical monitoring according to VDI 6041

We offer access via remote maintenance in addition to on-site service appointments to ensure the optimum performance of your plants. The so-called technical monitoring according to VDI 6041 plays a central role here: Monitoring serves to record, visualise and analyse plant states and operating data. The collected data can be used to benefit in several ways. Monitoring reduces capital-bound, demand-bound, operation-bound and other costs in accordance with VDI 2067 Part 1.

Your advantages are obvious: You benefit from the expertise of our specialists, shorter response times and can fully focus on your day-to-day business.
