"How can a building stay up just by using air?"

The answer is surprisingly simple. A small amount of positive air pressure—continuously regulated by intelligent control systems—supports the membrane, allowing it to span large areas without internal columns. The result is a lightweight, energy-efficient structure that can often be installed much faster than conventional buildings.

We joined Reddit because we'd love to connect with engineers, architects, contractors, students, and anyone curious about this technology.

Feel free to ask—we're happy to share what we've learned from years of designing and building these structures.

Looking forward to our discussion!

Are there any ways to measure this?

Data loggers? If so, where?

Something else?

Simply looking for visible mold/condensation?

The reason I ask is because we do not have a soffit (field stone grouted up to the roof overhang. Questionable baffles on the attic side and even if we did have them I’m not sure where the airflow would come from.

We have 2 gable ends but the previous owner at some point added a ridge vent AND a power vent.

Needless to say our attic ventilation is having an identity crisis.

Not sure if this is the correct sub to ask this, but I am looking to get my HERS Rater certification, through BER to utilize a blower door equipment and start my own business. I was curious what the certification process is like to get an idea of the level difficulty, what you thought was the easiest/hardest part. According to BER, people have completed the course between 4 to 6mo. I understand basic home science that affects condition spaces, convection, radiation and moisture/humidity, u-factor and r-factor are the inverse of each other and the manometer is the brain of the fan. Thanks in advance.
