Good looks different.
The heating systems in many of the municipal buildings in Bad Bayersoien are getting on in years.
It is now planned to improve the heat supply.
Bad Bayersoien - A few unpleasant things could be said about the heating system in the Bayersoier Dorfstadl. Andreas Scharli, for example, compares it to “the last shirt”. He doesn't treat the system in the neighboring building yard much nicer, he calls it “adventurous”. Since all the citizens' representatives only suggested approval with their looks, it was also clear to the audience that something had to be done in terms of heat supply in the municipal buildings. Maybe not immediately, because other things need to be clarified first. But soon. The ovens, explained Mayor Gisela Kieweg (FBB), are getting on in years. Time to think about how the buildings should be heated in the future.
The town hall chief has brought Scharli to the village for initial ideas. He used to be a heating engineer and has been advising the Oberland energy transition for eleven years, a community foundation that supports four districts, 92 municipalities and an estimated 440,000 citizens on their way to renewable energies. By 2035, the community has set itself the goal of cutting off fossil fuels in the southern Oberland. And they already know how difficult this undertaking is if you really want to use renewable or sustainable raw materials in all three areas - mobility, electricity, heat. In Valley near Holzkirchen, said Scharli, he recently helped set up a local heating network to which a castle, a kindergarten and 13 households were connected. His lecture began with this indirect indication of what is possible.
Two scenarios are outlined
The expert had looked at the three municipal buildings, Dorfstadl, Bauhof and Feuerwehrhaus, and sketched two scenarios: In the first case, the Bayersoier would only renew the existing systems individually, which are currently running on liquid gas and crude oil. Together they consume around 84 megawatt hours a year. The second solution would be a central energy source that the three public houses and possibly neighbors tap into. Scharli brought a wood chip heater into play and threw a diagram with the prices of the raw materials on the canvas. While the curves for gas, oil and pellets jump up and down, the line that shows the price of wood chips runs straight ahead at a constantly low level. As long as the conversion from spruce to mixed forest continues, “it will stay that way”, believes Scharli.In addition, the CO2 tax for fossil fuels is likely to rise considerably in the next few years.
He estimates the lifespan of a wood chip plant to be 30 to 40 years.
There is hardly any difference in price between the two variants.
Scharli reckons 70,000 euros for the individual retrofitting, 110,000 euros for the overall solution, with around 35,000 euros in funding in prospect.
It should be noted that he included a high proportion of his own work for these first sums and left out an external planner.
"A heating engineer with a brain can do it."
There is still a long way to go, but you have to start with something.
Mayor Gisela Kieweg
All of the local councils who answered believed the central system to be the better alternative, but pointed out a number of unanswered questions. Maximilian Drexler (GUD) recalled the event hall that both lists want to realize and that should be tackled first with a view to the heating. Andreas Baar (FBB) asked whether a new building is needed or whether the system is to be housed in the existing building, which is possible - albeit with greater effort. Rupert Haseidl (GUD) would like to “definitely include the private sector”. In this case, the expert noted, the administrative work involved in construction would be “quite a number”, but one that has to be handled - see Valley. Tobias Maier (GUD) recently brought the fire station into play, which is being redesigned. The wood chips could possibly be stored there.Despite the specific inquiries, Kieweg made it clear: Scharli's lecture should only be a first impetus. "There is still a long way to go, but you have to start with something."
