@Peter Sieben, ask questions, that is our purpose if we don’t understand. But, further research is a must, because that leaves open to more questions. Until, you find a person who is capable of answering your questions fairly. What I can tell you, how this video blog breaks it down, the end result, as the dwelling ages in time, the walls harden. The walls resist catching on fire, and is great for resisting mold, which concrete cannot or drywall on steel or wood studs. As mentioned in vblog, it draws carbon dioxide into the walls, so environmentally reducing the carbon footprint.

Actually, no pity at all - this is a realllllly good thing about hemp/hempcrete. If we don't reduce the CO2 soon, humans may not survive...and, according to Wikipedia, "The global average atmospheric carbon dioxide in 2019 was 409.8 parts per million (ppm for short), with a range of uncertainty of plus or minus 0.1 ppm. Carbon dioxide levels today are higher than at any point in at least the past 800,000 years.Aug 14, 2020" which is the real pity.

yeah they need to tap the mic input directly and not have another mic recording the presentation

A year late... These types of homes are built to be very airtight so they don't rely on poor construction for air exchange. They have powered ventilators that bring filtered fresh air in and out in a very controlled way. The incoming air is distributed into all the living areas and the outgoing air is taken from moist, smelly, or hot rooms like kitchens, bathrooms, and laundry rooms. You can temporarily set these ventilators to a boost mode to directly help mitigate a short-term heat or moisture increase. I should also mention that the incoming and outgoing airstreams travel through a heat exchanger. These ventilators usually run at a low speed 24/7. They can also have co2 sensor to increase ventilation if you have a lot of people over. In regards to additional cooling... If you are using multiple efficient mini-splits to cool your home you would only be cooling the zone that got warm and not the entire building. It's really not any different from what happens if you were to bake in the summer in a traditional building. The mini-splits and ventilators are all variable speed and you don't normally operate them at maximum. You can have a very targeted response to a heat spike without changing the climate in unaffected rooms.

So, how many times are you going to repeat your comment? I read it once and that’s enough. By the way I still think you’re right with your comment

Sure would of been nice if there was decent audio... Besides not being able to hear the questions... The guy in the middle, majority of time was very difficult to hear...
