Charlie Luxton's selfbuild involves a clever MVHR system, the Airflow Adroit - in this video Charlie discusses how it works and how it's been installed.
The Brine to Air Energy Collector is an interesting idea, with the extraordinary record breaking temperatures we had in the UK this year - how well did this technology work in cooling down the incoming air into the building via the Airflow MVHR system?
exactly my first thought - I was looking at heating a greenhouse passively and found corrugated piping was a real problem with moving over extended lengths....
Really interesting stuff... one of the things that strikes me when looking at a passivhaus is the increase in the volume of materials required to achieve it. This naturally has a carry-over in terms of the environmental impact and co2 footprint of that required extra material; I wonder what the trade-off is in real terms of additional co2 footprint from additional resources vs. reduction in co2 footprint of the house after the build... Also, because of the additional materials and increase in complexity of the build in order to achieve passivhaus, how much consideration has been given to the increase in toxity and VOCs from those additional materials/ chemicals used which will naturally have an effect on the inhabitants?
As most of the envronmental impact comes from from when the building is in use there is an overall benefit in the measures. The consideration to the materials used depends on the individual project/occupier. It would be my guess that MHRV is reducing the levels of toxity in a typical house. The same might not be true of a straw bale house with natural untreated furnishings etc.
It does - the MVHR removes stale air and moisture from the home, and replaces it with fresh air from outside. It pumps the old air outside through vents. It means the atmosphere inside is dry, warm and fresh.
what’s wrong with the air outside and making a huge window to open when you’re cooking? a 300 year-old house has survived, the occupiers reached a hundred y/o.. 🤷🏻
Would be interesting to know what his thoughts are now after running it for a bit.

Great system. Sounds expensive though.
Not sure those ducts are energy efficient. Corrugated flexible duct work of the length he’s using will have very high resistance due to friction.
It has a smooth antibacterial interior surface

@@CosmicSeeker69 corrugated pipe might be but this stuff has a smooth liner

Well what do you know, I have the same device. Only in here it's called Vallox, not Adroit. Specs and looks are the identical.
Does it extract moisture from the house and if so where does it go ?

@@HomebuildingMagazine How does it deal with moist outside air coming in? Is there a dehumidifier used on incoming air?

I think you may have missed the point somewhat. It's primarily about saving energy on heating and/or cooling.
