need help sizing a/c

steve_28

I am in the process of building a new home. The style is geodesic dome. I am trying to figure out how to size the a/c for it. I am wondering if anyone can point me to a formula or program that might work on that type of house? Or if anyone would like to try I can give you the construction/climate details.

Thanks,
Steve

PS: I have attached a couple of pictures of my house

interesting

Looking at your new house, the lower level seems easy as in total area, plus windows, exposure average deg. day etc... Do you know the area or total volume of the dome? I'm sure there had to be measurements when in the building process. I personally haven't sized a house like this, but I am interested in the final results.

dome

the total volume of the dome it self is 21,845 cu.ft. plus it sits on a 2 ft. riser wall , the dome is 45 ft. in dia. it is a fairly open floor plan, I was planning on using a 3 or 4 zone mini split ac system.

The accurate way

is a thorough Manual J. You can get a homeowner's registration of HVAC-Calc for $49. It's a very easy program plus you can give Don a call for any questions. Considering how much you are going to spend on minis, this is a cheap investment.
