It's an unfortunate by-product of airtight energy-efficient buildings that researchers at the Fraunhofer Institute want to fix.


There's something about secret doors that makes my spine tingle. The excitement! The mystery! But most secret doors are on the inside of a house — pull that book to reveal a hidden chamber! push that wall through! — this one, amazingly, is on the outside. It's so good you don't even see it.
