ᐅ Bedroom on the south side too warm?

Hello everyone,

We are expecting child number 2 and 3 next month. That’s why our current home will become too small, and we need to build. We plan to start construction when the children begin kindergarten. Nevertheless, I want to start thinking about it roughly now. We live in a rural area, and a plot of 1800 sqm (approximately 0.45 acres) with a slight south-facing slope is available (of which we want to build on about 900 sqm (approximately 0.22 acres)).

For a start, it’s important for me to know which rooms to orient towards the south. My idea is a bedroom facing south with a view over the valley (floor-to-ceiling windows). Waking up with the sunshine. That’s the theory; my concern is that later I might end up sleeping in something like a sauna. Do you have any experience with this?

PS: We were thinking of a KFW55-70 bungalow with Poroton 42.5 (brick thickness), but nothing is decided yet. Possibly a brine heat pump that might also provide cooling, and a canopy on the south side.

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

Our bedroom currently faces directly south. It has a standard-sized window, not floor-to-ceiling, with double glazing. It gets unbearably hot in the summer. The blinds are down all day, but that doesn't help much either.

I’m not sure how it is nowadays with well-insulated houses and triple glazing. You should install full shading options and possibly an air conditioning system. Having a view over the valley from the bed sounds fantastic—I would definitely go for it!

@BeHaElJa Silly mistake. With twins arriving in the next few months, you probably won’t be sleeping in for a while.

@Panama17 I’d prefer to avoid using an air conditioner.

Climate control using a ground source heat pump is an elegant solution.
Otherwise, large roof overhangs can also be very effective.

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