Is the bedroom on the south side too warm?

Hello everyone,

We are expecting child 2 and 3 next month. That’s why it’s going to get tight for us and we have to build. We plan to start building when the children go to kindergarten. Nevertheless, I would like to roughly deal with it already. We live in the countryside and have a plot of land of 1800 sqm with a slight south slope in prospect (of which we want to build on 900 sqm).

For a start, it would be important for me to know which rooms I should orient to the south. My idea: a bedroom with a view into the valley to the south (floor-to-ceiling windows). Waking up with the sunshine. That’s the theory: my fear now is, of course, that later I’ll be sleeping in a sauna. Do you have any experiences on your side?

PS: We were thinking of a KFW55-70 bungalow with Poroton 42.5, but that is not yet decided. Possibly a brine heat pump that might also bring in cooling and an overhang on the south side

The sun rises in the east Unless you sleep very long...

Our bedroom currently faces directly south. Regular-sized window, not floor-to-ceiling, double-glazed. It gets unbearably hot in summer. The shutters are down all day, but that doesn't help much either.

I don't know how it is today with well-insulated houses and triple glazing. You should install complete shading options and possibly an air conditioner. A view into the valley from the bed sounds dreamy, I would do it!!

Stupid mistake. With twins in the coming months, there probably won't be any long sleeping.

I would like to avoid an air conditioner.

Air conditioning via geothermal heat pump is a charming solution
Otherwise, much can already be done with large roof overhangs.

We have exactly that case and without air conditioning it just doesn’t work, at least during the few really hot days in summer... otherwise it’s great...
