Design:

up living spaces especially at kitchens.
Is this a bearing wall?If so, it will be a
little more work.
Remove?

Working Backwards:Normally we would first
calculate our Heat Load and then ask, “What is our best choice for
heating and cooling?”
Tonight we are impressed with the 25 SEER , 12,000 btu
Heating and Cooling unit from Fujitsu. We know it’s output.
Can we modify the building envelope to get the load down to where our preferred unit
will do the job?

Back Up Plans?What do we have for a backup plan for the few
hours it’s 10 below zero?
Or when the electricity goes out?
How will we get air to the bedrooms?
