Good evening everyone!
We are currently about to submit the building notification in Bovenden, just north of the city boundary of Göttingen (Lower Saxony), and we just had our architectural meeting with the architect from our home builder FIBAV.
During the meeting, the topic of roller shutters briefly came up, and we said that we do not want any.
The response was that we should or must consider an alternative type of sun protection.
For us, the issue was settled: we currently live in a rental apartment owned by a Göttingen housing cooperative, first occupied in 10/2014, without roller shutters.
However, afterwards I felt somewhat concerned and asked by email.
The very quick reply was:
“Summer heat protection according to DIN 4108 Part 2 is mandatory and is calculated by [...].
This shows which rooms must be equipped with shading.
Provisions for possible later shading systems can be integrated into the façade either before or after construction.
Please discuss this with your construction manager. He can then coordinate it with the trades.”
It’s good to know that summer heat protection according to the standard is mandatory—also to prevent the majority of people from retrofitting energy-intensive air conditioning later, no question.
But is summer heat protection also a legal or otherwise mandatory requirement, or can we omit it without facing any sanctions—worst case, a forced retrofit?
If summer heat protection is somehow a sanctionable obligation: does it have to be an external shading system?
My wife cannot live without curtains, so we already have some form of interior sun protection—of course less effective than external shading, but present.
We will not install an air conditioning system later...
Regardless of whether it is mandatory: What are the most cost-effective options for reasonably effective heat protection?
Or is that already provided by curtains?
Best regards,
Christian

HilfeHilfe21 Jun 2019 21:32Plastic shutters... may I ask why you don't want them? Starting Monday, temperatures in the Rhine-Main area will reach up to 36°C (97°F). Without shutters, the kids would be struggling.
Curtains do not provide any thermal insulation.
Nowadays, houses are built according to energy-saving regulations to keep heat inside. This primarily targets the colder seasons, but the effect also applies in summer. When heat is retained, it is difficult for it to escape.
Therefore, you can safely set aside any considerations regarding internal thermal insulation.
Good thermal protection is offered by external venetian blinds; if you do not want roller shutters, this would be the best alternative. Otherwise, I see no other option than active cooling.

For me, it’s an absolute must for a new build. Without shading, the house quickly reaches 25-30°C (77-86°F) and, unlike an older building, you can’t get rid of the heat easily because of the good insulation. We have the shading automated through KNX. Before I finished programming it, I got a preview of what missing protection would mean...

In our case, thermal insulation was only required for the living room.
Still, we only have four windows without shading: two facing north and two under the carport.
