ᐅ Shading of Roof Windows in the Living Room – Experiences and Tips?

Hello everyone,
we are currently in the middle of building. We have planned a bay window in the living room with two large roof windows measuring 220cm by 100cm (87 inches by 39 inches), really a special feature. Now we are looking for suitable shading options. Our concern is that the south-facing windows will cause the entire ground floor to overheat in summer (open floor plan).
One option would be roller shutters for each window, but that would completely block out the roof windows. A nicer solution might be an external awning, allowing some soft light to come in from above, ideally with a wind sensor to automatically retract it during storms. The downside is that on windy, sunny days we might still end up feeling like we’re in a greenhouse.
Does anyone have experience with this? Roof windows aren’t uncommon after all...
Thanks in advance!

Did the architect just design what the client wanted...? Given the low likelihood that anyone followed my advice to have a private semi-detached house planned by a shared architect, I assume this is a development project.

Anyway, external shading is necessary. In my view, the situation is comparable to a sunroom. With the difference that the exterior wall and roof are more solid and have a higher thermal mass. And that it is not a sunroom (which can be ignored if it gets too warm) but actually a main living room.

It doesn’t matter whether it’s an architect or a developer – the client must be informed according to the thermal insulation regulations.
Because of 6sqm (65 sq ft) of south-facing windows on the ground floor, installed vertically and not in the roof, we would have had to sign something if we hadn’t chosen roller shutters.
Unfortunately, the original poster does not answer my questions, so it might still be possible to backtrack a bit.
He is probably in a kind of shock 🙁

There are exterior blinds available from the two major roof window manufacturers (Roto and Velux), either as proper roller blinds or as semi-transparent sun protection elements. These should be easy to retrofit, as they are installed on the outside. Only an electrical connection directly at the window is required.

as a semi-permeable sun protection elementThese are exactly the ones I was talking about. But trust me, they’re good to have, although they really don’t help here! Even with a standard roof window, it’s still advisable to close the shutter during the day. Otherwise, it feels like a sauna in the evening. From my estimate, it reduces about 60% of the heat radiation.
Looking at the surface area, it does mitigate somewhat, but it still won’t create a comfortable climate.

According to the brochure, there are three options offering 75% and 90% sun protection and roller shutters. I also have a Roto window (southeast-facing) measuring 1400mm x 900mm (55 inches x 35 inches) in the stairwell. Even there, it heats up incredibly, so I need to retrofit something. Luckily, I can still run power from the attic.
