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...

Summer heat protection is really not necessary for the plot, as the large oak tree and other surrounding trees provide ample shade.
We were also advised against installing a photovoltaic system due to its lack of economic viability.
The suggestion of the planned canopy is great, thank you very much! Maybe a sunshade awning would even be enough?
Or perhaps covering the affected windows with sun protection film to satisfy everyone?

Summer heat protection is really not necessary on this plot, as in addition to the large sessile oak, other trees provide shade on the property.

The tip about the planned roofed area is great, thanks a lot! Maybe a retractable awning would already be enough?
Or covering the affected windows with solar control film to keep everyone happy? Well then. Just stick on the film, you can remove it later and everyone will be happy.
If a photovoltaic system is discouraged because of heavy shading, then it’s unlikely that 6 m (20 feet) lower down the living space will heat up to 120°C (248°F) from the sun. Usually, a roof, awning, or something similar will be installed on the terrace later on.
