Been trying to find a mechanical engineer who is capable to design an HVAC system for a super air tight and super insulated home:

R-30 walls
R-60 ceiling
Triple Pane Windows

The problem I am encountering is that most HVAC designers don't know how to properly design for an air tight and super insulated home. The home will require and ERV/HRV.

I've been thinking of just doing ductless mini splits in order to avoid the complication of ducts.
