My garage attic and garage stay 72 to 74 degrees all day. Costs about 10k to get it like mine and for us well worth the expense, because of the needed attic storage space....so maybe not worth it for villa attics??? I can't say because I've never been in a villa attic. I can say that the cool garage buffer space keeps the whole house cooler and my main ac will work less. Our house faces west and after noon the garage doors will fry your hand and or a ribeye. Before enacting my upgrades our garage was easily 120 degrees in the afternoon. Cool garages are achievable and less than what my Boss spent on custom closets
