Hello everyone,
I just wanted to briefly introduce myself and say thank you.
For about a year and a half, I have been a silent reader here to gather inspiration and especially to gain more knowledge about construction technology.
Now a bit about me:
After more than a year of searching for a plot of land, I was able to purchase one from a developer who couldn’t move forward quickly with his plans.
So we found our dream plot (good location, 2500 m² (0.62 acres), slight slope, underground private spring that we have to preserve and are allowed to use).
There was an old house on the property, which we have since demolished.
There is no zoning plan, so §34 applies. During an initial informal inquiry at the building authority, almost everything we planned was rejected.
So we submitted an official preliminary building inquiry, involved the right people, and had lengthy discussions. In the end, we received a positive decision.
Therefore, there is nothing standing in the way of the building permit. The building permit should be granted within the next few weeks as there are no changes from the preliminary inquiry.
My wife (37) and I (36) want to build a Bauhaus-style villa in southern Baden-Württemberg.
It will be constructed from concrete (with core insulation) or in combination with insulated precast elements.
A lot of glass (full-glass system), textile shading, KNX, fast network both wired and wireless, strong mechanical ventilation with additional cooling coils, stainless steel pool, large cistern, and more.
The electrical planning must be 100% spot on since it’s almost impossible to make changes afterward.
Since I am friends with an architect from a larger firm, it was clear which route we would take. Such a house can basically only be realized with an architect.
I also personally know the electrician and KNX system integrator, as well as the owners and work approach of the heating, plumbing, and ventilation companies involved.
Some trades have already been contracted, and part of the equipment has already been ordered.
I’m really looking forward to getting started and to the final result. The goal is to move in by the end of 2019.
Once again, many thanks for the information I have received from you so far.
If you have any questions, just let me know.
Attached is the design, though not the final version. There have been a few minor changes.
Greetings from Swabia

@sichtbeton82 Thanks for the compliments, but it won’t be that grand or special. I’ve seen other houses like that.
I also hope it won’t be shown anywhere. We are building it for ourselves, not for others.
Here I’m only sharing parts because I have benefited from this forum as well.
I have no ambition for my house to appear in magazines like Schöner Wohnen or similar.
I just visited the architect and finalized the facade design.
It will be matte concrete-look Alubond panels. Now, only the facade layout needs to be adjusted to the panel size.

Can you adjust the airflow rate using software, or is it set manually with valves and then only controlled via fan speed levels?In some areas, we can influence the airflow rate through electrically controlled valves in the ducts.
Manually at the inlet and outlet valves.
The fan speed levels change the overall volume flow but not the ratio between the individual areas.
Otherwise, the balance between supply and exhaust air will no longer be correct, especially in areas with airflow between rooms.
For example, if I have 3 supply and 3 exhaust vents in the equipment room, I can close 2 of each, and the ratio will still be correct because it doesn’t need to be balanced with other areas.
In practice, you will spend some time testing to find the right setting, program different scenarios, and then only retrieve the settings as needed. The valves in the ducts should be sufficient to achieve the desired variations in air volume.

Because of the significantly larger ventilation unit, additional ductwork, valves, and the cooling system, the costs are likely to be in the six-figure range even for smaller houses. The control system does not require much extra effort since a BUS system with a logic controller is already in place.
