Comparing Building Type Energy Efficiencies:
1. Post Frame building
As noted, a Post Frame building has larger wall cavities, which allows for ample amounts of continuous insulation. Furthermore, the wood framing parts have some R-value and provide very low heat conductivity.
2. Steel-frame building
This type of building would require insulation to be sandwiched between the outside steel and the framing. This causes the insulation to get crimped in “waves” around the building. Compressed insulation has very little R-value. In addition, the steel columns act as power bridges, transferring heat to the outside during the winter. In fact, steel conducts heat 310x faster than wood.
3. Concrete block building
Block by itself provides very little insulative value. The blocks’ cores can be filled with insulation. However, that provides uneven R-value because the cores constitute only a portion of the block. Typically, to get a block building warm and sealed tight, additional work must be done. Furring strips can be attached to the block and then insulation applied between, or stud walls can be built and insulated.
Bottom line is that Post Frame buildings provide the best type of energy efficiency for your building.
