We are finalizing specs for a new build on a south-facing lot and the HVAC zoning is stressing me out.

I want to make sure the kids' bedrooms upstairs don't turn into a 40-degree sauna during January. We looked at some energy-efficient display layouts from a company(I think it was called 101 Residential) that use smart zoning for the ducting, but I am still on the fence about lightweight cladding vs double brick for the upper floor. The draftsperson says the R4.0 insulation batts are enough to stop the heat transfer.

Planning for a 14kW ducted system with 4 separate zones, but if the thermal mass upstairs is garbage, the power bill will destroy us. Are you guys running double glazing or extra cavity insulation in the western walls to counteract this?

Landing in Porto on Tuesday for 4 days. Staying near the Ribeira area but I'm planning to do a lot of walking up those hills so I'll need maps working 24/7. Roaming with my current plan is $12 a day which is ridiculous for a short trip. Any cheap esim recs for Portugal? 3gb should be plenty.

Edit: thanks for the help guys. i went with eSIMX. found a plan for $3.50 and the best part was buying one for my wife in the same checkout. saves me the 20 mins of troubleshooting her phone when we land. got 10% back too.
