Hi guys. *My wife and I are in the late planning stages of building
our new home. *I want it to be as energy efficient as possible. *We
are having a slight disagreement.

I want foam insualtion in walls and attic. *She is ok with that.. *What
we disagree about is how to do the attic.

Her ex-husband is a HVAC contractor. *He says we should use the " foam
the underside of the roof, seal the attic and semi condition it"
method. *Our builder agrees.

My problem with that is, why would I want to semi condition an area
the same size as my house if I am never going to use it for anything?
I want to foam the attic floor, and make sure the attic is well
venitaled. *Why is allowing my warm and cold air (that I am paying *to
heat and cool) to migrate up into my attic a good idea? *Isn't it more
efficient to keep that expensive air in the house by well insulating
the attic floor?

Can anyone give me advice on why my thoughts are wrong?

You are right you will be heating the attic from migrating heat loss
up, the builder will be happy to agree since it will take more foam,
more foam means a bigger job, more money. If you are foaming
everything you are including a heat recovery ventilator for that tight
house.- Hide quoted text -

I hadn't explored the heat recovery ventilator. *I'll need to research

Then You AC pro aint no pro because a fomed house is like living in a
foam cooler, its doent breathe or have enough air exchanges per hour
to keep you healthy, google overtight houses that dont breathe, sick
house syndrome, do research now and maybe hire an architech because
several ideas you plan dont make sense, maybe alot more dont.- Hide quoted text -

not a detailed planning session, he wont be the HVAC contractor. *i'n

WTF, you allow her EX to put in his 2 cents! Thats your problem, ban
him. Even worse, he is an AC contractor not contracting.
