ᐅ Proper Ventilation After Completing the Structural Shell, Windows/Doors, and Roof

Hello everyone,
By now, our shell construction including the basement (Schlagmann Poroton T8 filled) with windows, construction door, roof insulation (Pavatex), and roof covering has been in place for two weeks. The pull-down attic ladder is not installed yet, so the opening is still there.
The screed/plaster will be applied after the frost period ends in March/April. We are in no hurry and wanted to give the shell construction some time to dry over the winter.
What is the most effective way to do this? According to our general contractor, it is best to keep the windows slightly open on tilt all the time, only closing the side facing the weather (west). However, if no rain is forecast, this side is also tilted open overnight.
Currently, we open the windows in the morning and close them in the evening, including the roof hatch. If there is a higher chance of rain, the windows remain tilted open, and the west side stays fully closed.
Is this approach okay, or are there more effective methods?
Thank you for your opinions.

Hi,
leaving all windows tilted open to create ventilation initially sounds reasonable to me.
But just out of curiosity: why are you pausing construction now? The bricks already have a very low moisture content, so there isn’t much drying needed. The main sources of moisture come from the screed and plaster. Compared to that, the adhesive mortar between the bricks is negligible. In other words, drying and pausing would make much more sense after applying plaster and screed.
Best regards,
Andreas

Hello!
Yes, we are aware that the major moisture only appears once the plaster and screed are applied.
This was actually planned from the beginning since we only started construction at the beginning of October and there is no heating or electricity yet to warm the screed.
Before Christmas, the rough installation of the plumbing and drainage on the property will be done, then the electrician will come in January, and from March onwards plastering, screed, and so on will follow. At that point, we would also like to run the drying program twice, as there is no rush. Move-in is planned for September/October 2017.

wanted to give the shell structure some time to dry over the winter. With our winters, I would be more concerned about the rain soaking the bricks. But in Bavaria, it probably gets nicely cold . Still, what exactly is supposed to dry there? I wouldn’t worry too much before applying plaster and screed.
