Hello,
for our new house construction, for which the building permit / planning permission is currently being processed by the district authority, we received information from the structural engineer via our general contractor that the summer thermal protection in the living room unfortunately cannot be met due to too much window area in relation to the room size.
They pointed out that summer thermal protection is regulated in the thermal protection certificate according to the Building Energy Act 2020. This is a legal requirement and must be complied with. The recommendation is to install solar control glazing, which I find very unfavorable because it would make the room darker year-round.
The absurd part is that there is a huge oak tree on the south side of the property, so the living room windows will be in the shade for most of the day.
Another alternative would be roller shutters, costing around 3000€, for something we will never need for the reasons mentioned above.
The solar control glazing would be about 1000€ cheaper but would significantly reduce the living quality.
Is there any affordable way to meet the thermal protection certificate requirement? Due to the shady property, the risk of overheating the room is absolutely not expected...

When the sun is high in the summer, the tree would have to be very close to the house in order to cast shade. Also, such a tree only has a limited canopy width. So there could be several hours when the tree does not provide any shade.
I would choose venetian blinds (also called external blinds or louvered blinds) instead of roller shutters for the living area.

Maybe a roof over the "assumed" terrace would be enough, which would only be built "later."This would also have the advantage of providing rain protection, a question that definitely comes up after the first soaked gathering.

And with well-designed floor plans, you can definitely shade the sunny side without ending up sitting in the dark.

Of course, having plenty of sunlight in the house during the transitional seasons is great. And in summer, you’re outside anyway.
