hvac building Systems

< HAVC Engg what are things to be consider in Building a Pre engg building>

You must be in a tearing hurry!

Maybe you asked:

• what is HAVC Engg ?( You began -- hvac building system)
• what are things to be consider in Building a Pre engg ( engineered?)building?

If my guess is right- you asked for : H eating V entilating and A ir C onditioning.

Second part is puzzling . But let's guess just 2 :

• Must not allow too much heat to store in roof/wall to radiate in--later. (in theTropics)
• Must have tight sealing doors/windows to frames(in Cold countries)
