Climate protection and the sustainable use of resources are the major challenges of our time. In order to achieve the socially-anchored climate goals, it is above all necessary to increase energy efficiency on the consumer side in addition to increasing the use of renewable energies. There is enormous potential for saving energy, especially in the industrial and commercial environment. Increasingly complex legal requirements to improve energy efficiency in companies as well as continuously rising energy prices motivate to optimize energy efficiency.

The specialist area of energy technology / efficiency offers client-oriented engineering services ranging from measurement-supported inventory analysis to the planning of optimized overall energy technology solutions, as well as consulting and support services relating to the topic of “climate neutrality”.

What is an energy management system?

Energy management systems are sets of rules that help companies plan their energy use in the daily production process and achieve continuous improvements in energy-related performance. This not only saves energy, but also reduces the CO2 footprint and ultimately significantly lowers energy costs. Further benefits: the efficient use of energy increases competitiveness and creates a positive image when it comes to sustainability.

GICON® develops management systems and integrates them into your existing company processes. In selected industrial sectors, our proprietary software solution CoCheck can be integrated for this purpose.

The introduction of an EnMS is recommended for all energy-intensive companies in the production sector. If electricity consumption exceeds 5 GWh and a certain electricity cost intensity is exceeded, it is even required by law. The latest standard is the energy management standard DIN ISO 50001:2018.

Is it worth integrating renewable energies into existing and new buildings?

Yes, the "Act on Energy Conservation and the Use of Renewable Energies for Heating and Cooling in Buildings" (Building Energy Act - GEG), which came into force on November 1, 2020, contains clear new regulations in this regard:

  • With immediate effect, an operating ban applies to old boilers that have been in operation for at least 30 years and are fed with liquid or gaseous fuels
  • The installation of new oil and coal boilers will be prohibited from 2026 or only permitted under defined conditions; oil hybrid solutions will also be possible in most federal states in the future
  • Retrofitting obligation: a central heating system must be equipped with automatic devices for reducing and switching off the heat supply and for switching electrical drives on and off by September 30, 2021. Room-by-room control of the room temperature must be retrofitted
  • Prohibition of deterioration in energy quality: decommissioning of solar thermal systems, for example, is not permitted unless compensatory measures are implemented at the same time

Irrespective of the existing buildings, the following new regulations will apply in future:

  • Renewable energies must be used in new buildings or compensatory measures must be taken
  • The GEG provides greater support for sector coupling than before:
    - In order to promote the use of renewable energies, electricity from renewable energies (e.g. photovoltaics) can be counted proportionately (cross-sectoral use of renewable electricity is permitted)
    - To determine the annual primary energy requirement, renewable electricity can also be taken into account
  • The so-called neighborhood approach is new: in the case of changes to existing buildings that form a spatial unit, compliance with the requirements can be demonstrated through joint fulfillment in the neighborhood (joint heat supply and balancing, for example). The entirety of the buildings in question is always considered
What benefits do our customers gain from the close cooperation between the construction planning and energy efficiency departments?

GICON® also supports its customers in the planning of new buildings according to the latest criteria. A separate department with more than a dozen employees takes care of all aspects of construction planning (civil engineering, structural engineering, technical building equipment) from a single source. In combination with the "energy technology/efficiency" department, we deliver a complete package that is always geared to the customer's requirements.
