Thread: Potential Manual J error
03-09-2005, 05:30 PM #1
I checked the builder's Manual J and I'm concerned about it having no heat gain from the exposed basement walls. The wall is 53 ft, faces the west, is brick and has four windows and a french door. Also they have no heat gain for two 30 feet north and south walls where they start above ground and end below ground.
They do have 3,100 gain for the basement and added latent gain of 4,500 for 7,600 total basement heat gain for our walkout basement. Also they have no loss for ductwork.
Does this sound correct?
