ERV or Central fan integrated ventilation best for hot humid climate?

I read an article by Martin Holladay who said ERV could actually make the situation worse in hot humid climate during those days when temp and humidity level are mild. That confused me. I would appreciate answers to questions about the best vent. system for a new build air tight house at approx. 2200 sq ft, in zone 3A below the red line. Heat pump HVAC system.
1. Why might an ERV make matters worse on mild days with low humidity?

Insulating under footings?

Hello, I'm building a house for my parents in northern British Columbia. We are shooting for a superinsulated and air tight building. It's will be a story and a half, on an ICF foundation crawl space.

Planning on doing the GWB, 2x6 (structural/utillity chase, with either dense-pack cellulose or rock wool batts),1/2" ply (taped to become the vapor/pressure boundary) with a 12" Larson truss on the outside of that (dense-pack cellulose), then WRB, rainscreen, Hardiplank.

Planning on beefing up the ICFs with 6" of EPS on the outside, with also 6" of EPS under the slab.

Hot water heater strategy

Been thinking about the best way to set up my hot water heater system and wanted to bounce my idea past the readers of GBA.

Zone 5A - Central Illinois. Water heaters will be located in basement. Family of 5 (3 young kids) with plans to accommodate elderly parents if necessary in the near future.

HVAC system is a 3-ton GSHP with desuperheater that can provide some water pre-heating but not enough to meet DHW demand by any means.

Best insulation for a mix of brick & wood?

There's a lot to be found about insulating brick, and about insulating wood...but what's the best solution for interior insulation for a combination of both? This is for a wall in a multi-wythe brick home, and this particular area has some wood framing in it (the wood frame goes to the roof of a portico). (See photo)

My instinct is to use rigid foam, pressed up as close as possible to close conductive loops. But clearly, there will still be lots of air in the wood-framed area.

What's your take on this?

Wood basement drainage?

My understanding is that very well executed drainage is vital to the success of a PWF basement.
The designs I've seen typically have a crushed rock or washed gravel layer under the basement's walls and floor, 4" or 6" thick. They also backfill at least 1/2 way up with the drain rock. My questions are: Would a 1" layer of Roxul " Drain Board be a proper replacement for the back fill rock? Is filter fabric on the outside of the wall's drainage medium needed?
