Thanks for sharing this! It's interesting how security systems are now being integrated into window and door technologies — especially in energy-efficient buildings like Passive Houses.
When talking about modern features like bar code entry, it's also important to consider the type of doors being used. For example, a
tilt and turn door is a great addition to any Passive House setup. It combines airtight sealing (perfect for energy efficiency) with practical ventilation and security. You can tilt it open for airflow without fully unlocking the door — which adds another layer of protection, especially when combined with smart access systems like the one you mentioned.
I think integrating both energy-saving features and modern security (like card access) into doors like the tilt and turn design makes Passive House projects even more future-ready.
