ᐅ Are external blinds necessary on the east side?

I would decide here based on budget, room usage, and exterior appearance, rather than heat protection.

On the ground floor, we have a 12m² (130 sq ft) corner room used as an office with windows facing south and east, both fitted with Venetian blinds because we didn’t want curtains and preferred not to mix roller blinds and Venetian blinds in the same room. We have some trees to the east, and the sun is low in the morning.

I noticed that this summer, until just now, I forgot to include that east-facing window in the automatic timer for heat protection. It makes no significant difference whether the window is shaded or not. Our front door, which has a lot of glass and also faces east, hardly causes the hallway behind it to heat up. The house is built with solid construction and has a lot of thermal mass inside.

On the upper floor, we have roller blinds on the east side for the bathroom and bedroom, and I wouldn’t want to do without them.

External shading always helps, but if the windows aren’t large, you can also do without it on the east side.

Like others, we chose a mix. We installed external venetian blinds only in the open-plan living, dining, and kitchen area. The rest of the house has roller shutters. We would do it the same way again. This way, you get both shade and natural light in the main living areas where you spend a lot of time, while the bedrooms remain dark. Of course, everyone has to decide for themselves what they prefer.

We also have venetian blinds in the sunroom (south and west) and in the office (south). All other windows have electric roller shutters.

Or is it "not done," and should you install external venetian blinds everywhere if you already put them on the south and west sides?

I often get the impression that people just follow trends without considering whether it makes sense. My reasoning is:

First)
The east side gets morning sun, which usually isn't very intense;

Second)
Summer enjoyment is significantly reduced if you can’t appreciate the view of the blooming landscape because you keep the blinds down all day long throughout the season just to prevent the living room from turning into a sauna.

Therefore, I would mainly opt for reasonably sized windows and assign each window its optimal shading solution.

Ultimately, it should be demonstrated by the thermal insulation certificate for summer heat protection, possibly according to DIN 4108-2. Often, a mix is used for cost reasons; I prefer a consistent architectural approach here.

I agree, but the optimum solution is often not affordable. For south-facing windows, for example, an adequate roof overhang that provides sufficient shading would be best. However, this often becomes very expensive (for example, with a concrete flat roof using insulation baskets, etc.)...
