ᐅ Windows & Window Sizes: What to Choose? Double-Hung or Casement Windows?

Hello,
for our bungalow, we have partially planned three windows measuring 138.5cm by 126cm (55 inches by 50 inches) in height, and one window 138.5cm by 76cm (55 inches by 30 inches) in height. Given this width, would it make sense to use double casement windows? Do such windows even exist?
Since we have not planned for a mechanical ventilation system, we will be ventilating frequently. With ventilation, relatively wide single casement windows will open fully into the room, which I find disruptive. Over time, this could also cause sagging due to the weight and long lever action. Additionally, if there is a flower vase or other items on the windowsill, they must be completely cleared away when ventilating. With double casement windows, on the other hand, you can simply slide one side open to the side.
Thanks for your advice

For 2 years and 3 months without a ventilation system… just ventilating once in the morning for 10-15 minutes. No mold or anything similar…
The blower door test back then was 0.3…Bautraum2015 schrieb:
Here, two years without a mechanical ventilation system with heat recovery, all good!!
And very good air quality thanks to many natural building materials (oiled wood on floors and furniture, lime plaster, and mineral paint).One question: (actually belongs to another category in the forum but fits well with this discussion)
@Basti2709, @Bautraum2015, you didn’t install a ventilation system. Do you have exhaust fans in the bathroom, toilet, and utility room?
Our contact from the builder, who worked for many years as an energy consultant himself, told us that without a mechanical ventilation system, proper window ventilation will prevent mold issues (which I also believe). He also said that in the bathroom, guest toilet, and utility room (with washing machine, condenser dryer, and sink, no window but with a secondary entrance door), an exhaust fan is really not necessary.
(Our bathroom will only have 4 corners, so no recess or shower enclosure, just a curtain.)
Do you or maybe anyone else have experience with this?
We have been living here since the end of December, without a controlled residential ventilation system. There are fans in the bathroom and the utility room, but we also hang quite a lot of laundry to dry in those rooms. In the bathroom, we would probably manage just by ventilating through the window, but the fan in the utility room does run more frequently.
I’m not sure if it’s absolutely necessary, but having a fan there definitely contributes to my peace of mind.

Do you or maybe someone else have experience with this?No... nothing like that installed... all ventilation is only through the windows.
We also dry our laundry in the utility room (about 11m² (118 ft²))... but I make sure to ventilate there frequently.
Even there, no signs of mold or mildew.
As long as everything in new buildings is constructed properly, mold is rarely an issue. It mainly occurs in cold spots where the dew point is undershot.
The main factor is air quality. In most cases, a mechanical ventilation system with heat recovery achieves close to zero energy loss. It is also considered a significant comfort improvement. Everyone I know would never go back to living without one.
By the way, all buildings with exhaust fans also have active ventilation—just without any control.

Hi, another question about the window size.
We also want to install double casement windows now.
What size works well?
Has anyone here found their double casement window
to be too large in hindsight?
We are planning rather large double casement windows and aren’t sure if they might look too big.
Attached are our planned windows as an example
(the window is not centered yet and will be adjusted, the faucet issue will also be solved later, for now it’s just about the window size in relation to the room)
