Conductive Heat Loss/Gain

• Downstairs walls upgraded to 6 inch thickness to allow more insulation
• Fiberglass batts used in thick vertical walls, floors, dead spaces and attic
• Sprayed-in Icynene used for tight areas, remaining 4" walls and cathedral ceiling in family room
• Fireplace chimney butt insulated
• Windows and Doors upgraded to be thicker, use thicker panes.

 Radiant Heat Loss/Gain

• Dominant form of heat gain through roof (summer), dominant form of heat loss down through floors (heating), significant in sun-facing walls (summer).
• CBF Ultra Foil bubble radiant barrier installed under radiant floors and walls, under heated slabs. Foil barrier in attic.

Convective Heat Loss/Gain

• Outside air heat exchangers introduce fresh air, without significant heat loss
•
