Does it make sense to centrally supply a new development area with heat?
This question was recently asked by the local council in Peiting (we reported).
At the most recent meeting there was an answer from an energy expert.
It read: It depends.
Peiting - As is well known, the municipality of Peiting is currently promoting new construction areas in several places.
The type of heating that future builders will choose is up to now up to them.
But does that still make sense in view of the required energy turnaround in the future, or shouldn't the municipality better specify a central energy concept when designating building land in the future?
It is a question that has come up more and more recently, said Andreas Scharli in the most recent local council meeting.
The Oberland energy transition expert accepted the market administration's invitation after the committee had decided in July to consult an expert on the complex topic (we reported).
Modern houses only need little energy
The question of whether a local heating network makes sense for a new development area always depends on the local conditions, said Scharli.
It is only economically advisable if there are large consumers in the vicinity.
“The crux of the matter is that modern houses require little energy.
This is not of interest purely for single-family houses. ”The energy expert referred to the example of Valley in the Miesbach district, where a kindergarten, elementary school and Valley Castle were available as buyers near a new development area.
"It's worth it."
So-called cold heating networks, in which energy is generated centrally, for example via geothermal probes, would be more likely.
However, the organizational effort is high here too, after all, the network has to be operated by someone.
“Municipalities do not normally have the capacity for this,” the energy manager knows from experience.
Easier to provide land with heat probe
It is easier to equip every plot of land with a heat probe when it is developed.
The costs for the drilling could then be accounted for in the same way as water and sewage via the development costs.
“It is up to the builder to make use of the offer.” Groundwater heat pumps are another option that can be used jointly, says Scharli.
Regardless of the heating system, the easiest way for municipalities to implement it is, of course, to make specifications regarding the efficiency standard of the houses in new building areas.
The better it turns out, the lower the energy consumption.
Habach, for example, has already successfully chosen this path, the expert pointed out.
Use waste heat from companies in the industrial park?
Scharlie's lecture met with great interest in the committee, but it also raised some questions.
Thomas Elste (Greens) wanted to know whether it would pay off in the case of the planned construction area between Zugspitzstrasse and Bergwerkstrasse to use the waste heat from companies in the nearby industrial park.
To do this, one would have to take a closer look at the companies, replied the energy manager.
Is there production there every day or only from Monday to Friday, which would mean that no heat would be available on the weekend?
“It's definitely worth a try,” said Scharli.
As the Oberland energy transition, they are happy to provide advice and assistance.
In general, there are certainly some areas in Peiting where a heating network makes sense.
"That would have to be examined more closely," said the expert, who pointed out the possibility of an energy use plan.
This gives an overview of the current and future energy demand and energy supply situation of a community.
The creation is funded with 65 percent, said Scharli when asked by Christian Lory (Independent).
Criticism of insulation material: at some point "the garbage will fly around our ears"
Andreas Barnsteiner took the discussion as an opportunity to get upset about what, in his opinion, is an unpleasant result of saving energy in building.
At some point, all the insulation material has to be disposed of.
“The rubbish then flies around our ears.” Of course, Scharli didn't want to leave that.
In many cases, ecological insulation materials are already being used.
"With the energy transition you always have to justify yourself for everything that doesn't matter elsewhere."
Mayor Peter Ostenrieder (CSU) thanked Scharli for the "exciting approaches" at the end.
The committee did not make a decision.
