I'd love to see a video about the differences in performance and cost (material and labor) between rigid exterior insulation outside the WRB + a single stud wall vs interior thermally broken double stud wall, with all insulation inside the WRB. I think this kind of comparison would be very helpful to a lot of viewers.

The clip product is called Crossfix by EJOT - a German company. The clips are stainless steel and are part larger system used to mount cladding on buildings. Typical use is commercial, but this looks like a great use on residential building. I have a crappy early 90s house that I am considering coccooning in rockwool outsulation, covering the exisiting brick and everything. These clips might be a good choice.

That is a really well designed and built house! Steve didn't specifically mention the drainage membrane rapped around the foundations, but you can guarantee there is a french drain around the entire property; the membrane is there to ensure that any water that approaches the house will be drained away from it quickly.

There are a bunch of different manufacturers making similar clips. In Canada, we also have ACS A-CLIPS (made up of two pieces, so it's adjustable in depth) made by Soprema (same people who do waterproof membranes. I can't remember the name of the manufacturer, but there is one up here who makes thermally broken, adjustable type. One part is made from glass fibre, and attaches to the wall, and the other type is steel (I think) which is used to attach the exterior cladding.

Can't the furring strips be place flush up against the insulation? The mineral wool could still drain reasonably well, and it's got plenty of ventilation in the adjacent cavities. What about pressure equalization and wind driven rain? An excessive gap could also lead to more rapid movement of air during a cladding fire.

It's got a water-proof coating, so, in theory, it doesn't need it. For buildings where you want a very long life (100 year+), you might want to add a breathable weather barrier over rockwool, but you'll always have penetrations for the brackets going through that barrier, so doing it properly would require a weather seal for each bracket.

I've tried hiring folks over and over here in the states, and they're only interested in slapping crap together they way they've always done it, or they will take (all) your money to do what you want and either screw it up royally, or cut every corner they can the second nobody is looking!

No wonder houses in Vancouver are among the most expensive in the world. The builder who did my house is a certified R2000 builder but only uses the things that make sense. I’m a very long way north of the house you featured and I’m pretty sure the added costs of that kind of building would be more than a lifetime of savings in heat costs. Vancouver is a pretty temperate climate so I doubt it’ll ever pay out unless our idiotic leaders raise the taxes on heating to the point where they artificially force it to happen. But that’s the kind of thing they just love to do while bragging about how environmentally wonderful they are. That coil around the drain is an inefficient water/water heater exchanger. It’ll work when using hot water only. I think a horizontal run would be a better place for it although an actual heat exchanger would be more efficient but more expensive and prone to blockage. The coil is simple which is usually good.
