Hello, we have received information from the structural engineer through our general contractor for our new house construction, for which the building application is currently with the district authority, that the summer heat protection in the living room unfortunately cannot be met. Too much window area in relation to the room size. With the note that the summer heat protection is regulated in the heat protection certificate according to the Building Energy Act 2020. This is a legal requirement and must be complied with. The recommendation is the installation of sun protection glass, which I find very unfavorable, as this would make the room darker all year round. The absurd thing 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 most of the day. Another alternative would be roller shutters, another 3000€, for something we will never need for the above-mentioned reason. The sun protection glass would be about 1000€ cheaper but would significantly reduce the quality of living. Is there any cheaper option to fulfill the heat protection certificate? Due to the shady property, the risk of room overheating is absolutely not to be expected...

I'll throw early summer into the mix. Still few leaves on the trees, but the sun is strong and it will get warm. Take the blinds, you'll be glad to have shading.

I agree with my predecessor. Never underestimate a new building. We lived in a KFW55 house for 2 years and you can't imagine beforehand how much rooms heat up just from the sunlight coming through the windows. Even in April/May already. We had a sunny spring one year and wondered why we constantly had 28 degrees in the living room while it was only 20 outside. That one oak probably won't save you there.

Shutters on the windows where you can nicely look outside? I find that bad. If then, venetian blinds.

Maybe it is enough if you make a window a little smaller?
Otherwise, I would take roller shutters; at least you can use them at night if you don't need them during the day.

The office certainly assumes that such a tree could also be cut down at some point. Of course, I do not wish that for the tree, but I would arrange my house to at least provide the option of shading. Perhaps a roof over the "supposed" terrace, which would then only be built "later," is sufficient.
