Heating halls in compliance with GEG from 2024 - but how?
How will Germany heat from 2024 according to Federal Minister Habeck? First things first: the final answer is not yet available. This is because the draft for a new Building Energy Act (GEG) has only just made it through the cabinet. The next step will be to ask the Bundestag and Bundesrat. Nevertheless, the announced "end" for gas and oil heating systems has been making waves for months. And caused so much uncertainty that last winter, instead of investing in the energy-efficient refurbishment of their hall heating systems, industry often preferred to reactivate old oil and coal heating systems...
In the new GEG ("65 % renewables for every new heating system from 2024"), the special features of "non-storey buildings" such as industrial and commercial buildings with their typically high ceilings are given due consideration
Compliance with the new legal requirements (GEG from 2024) is ensured with FUTURA both in the renovation sector and in new builds. This is demonstrated by excerpts from the draft bill
- IR heaters operated directly by electricity with complete coverage of the heat demand automatically fulfill the requirements of the GEG in the hall area without additionally falling below the minimum requirements for structural thermal insulation (§71d (4)).
- The installation of a gas heating system that is capable of, to burn both natural gas and 100 % hydrogen ("H2-ready") also meets the requirements. Natural gas can initially be used for this, subject to compliance with a binding transformation path to be submitted by the gas distribution network operator in accordance with Section 71k. The conversion to hydrogen operation may only require limited structural changes to the heating system (currently proposed here are "a maximum of 20-25 % of the original investment costs").
- Any combination of the two previous points - such as the FUTURA multi-energy infrared heating system - is also a fulfillment option within the meaning of the new GEG (§71).
For the renovation of hall buildings, the great energy-saving potential of efficient decentralized heating is also further taken into account by the new GEG
- The installation of a highly efficient decentralized hall heating system is also possible here (in addition to the options mentioned above) without feeding in renewable energy: If 2 years after the installation of the decentralized heating system in halls (> 4 m) a saving of at least 40 % over the period of one year is proven, the basic requirement for the use of renewable energies according to §71 does not apply. The background to this is that the requirement for renewable energies is assessed here on a par with the saving of useful energy and is equivalent. Multi-energy systems such as FUTURA therefore meet the planned GEG requirements in several respects. And this is achieved through greater comfort and effective heat transfer via infrared with precise temporal and spatial allocation (e.g. zone heating). Another advantage for operators of industrial and commercial buildings is that the investment costs saved can be used to invest in a PV system. This increases the energy self-sufficiency of companies and at the same time leads to a reduction in energy costs. This is also an advantage in terms of decarbonization: the innovative Infaro heaters accompany their users into the future with investment security - beyond the year 2045. And all this with optimum comfort, perfect usability and unique multi-energy capability.

"No energy transition without energy efficiency" is the title of dena's "Topics and projects" section on its homepage "The best kilowatt hour is the one saved," says Thomas Kübler, Managing Partner of KÜBLER GmbH. Both mean the same thing: It's about curbing energy consumption in general and especially in companies. Because this is an enormous lever for achieving climate targets. And that's not all: energy efficiency also pays off economically if it is approached in the right technological way. Modern infrared heating technology plays an important role here, especially when it is intelligently combined with Bennwert technology.

The horrendous rise in energy prices, the fear of Putin stopping supplies, the demand for renewable energies to combat climate change - all of this is currently causing a great deal of uncertainty. Is it still worth investing in gas-powered industrial heating systems? The answer to this question is important. Because it determines how quickly trade and industry will make their contribution to the energy transition. And how well it will be possible to meet the future requirement of climate protection in an economically viable way.

"Heating with the windows open" in private households is like "heating with the doors open" in production halls and warehouses. It's great if you can afford this in industry and commerce because production and business are obviously running - unfortunately, this is not a matter of course for many companies in times of coronavirus.
