Bauhaus concrete villa with core insulation - experiences

The garage is only intended as a parking space for the vehicles. Of course also bicycles, some tools, etc., but no hobby workshop or anything like that. It is within the thermal envelope and receives warm air through the generously sized controlled residential ventilation. But no radiators or underfloor heating. Do you have a link to your project? I would like to take a look at it too.

We installed heating in the garage. I would do it again anytime. Controlled residential ventilation is never enough to get any significant heat into your garage. Otherwise, the drafts would be way too strong. With controlled residential ventilation, you can neither heat nor cool... that's at most sales talk.

How fitting. We are on our way to the architect and hope that we will then be ready for the building application. Therefore, thanks again for the garage dimensions. That is also on our agenda today. Edit: the plan is a double garage with an interior dimension of 6x6. That should be enough, right? Bicycles will have their own shed. Heating/ventilation probably not, I still lack the appropriate equipment for that.

of course you can heat or cool with air. The air exchange rate just has to be above 4. It is also insulated. With a normal exchange rate of 0.3 I agree with you that it is sales talk. We don't have a "normal" controlled residential ventilation but additionally a large air conditioning unit in the supply air. As soon as you put a warm car with a big engine inside, the temperature rises anyway. We also only want to warm it a little and not the same temperature as in the house. It's enough for me if I still have 10 degrees in winter to comfortably wash a car with rinseless.

6x6 as a double garage is comfortably spacious. Of course, with more width you could open the doors even more comfortably. I would at least plan a duct ventilator with heat recovery. (Electricity). This way you get some of the moisture out. Do you want drains in the garage? Hot and cold water connections? Have fun with the architect.

If you run the controlled residential ventilation with an air exchange rate of 4... then have fun in the drafty hut. It seems to me... you were very badly advised here! When our controlled residential ventilation runs at 200 m³/h (with a 1200 m³ house volume) I already feel the draft near the doors at my feet. Rate 4 would then be 4800 m³/h for us. That’s technically certainly feasible but absolute nonsense and no one does that.

If you feel the draft at the doors, they are overflowing. Most areas in our facility have separate supply and exhaust air. I have the right people on board: a renowned HVAC company (500 employees) + a specialized company for air conditioning systems. And Helios doesn't know anything either. I also know the bosses. Have you ever been in the cleanroom of a chip manufacturer? The air exchange rates there are totally different, and you don't get drafts. It always depends on where and at how many points you introduce and extract air... As I said, a normal controlled residential ventilation system is not meant for cooling or heating. Large exchange rates also cause problems (draught and noise). Properly planned and executed, air for cooling or heating is proven. A split air conditioning unit also blows air into the room. We just have a large central split unit.
