SPX Advanced Steel Panel Wall Technology
The Economics.
Objective information on Thermally Efficient Technologies

Some of us can remember buying our first desktop computer, where we likely paid over $3000 with all the bells and whistles, thinking we would not be replacing that computer for a long time.  Fast forward 20 years, and we soon realize technology advances so fast that computers today cost less than $500 and old computers quickly go out of date.

The same logic applies with new technologies designed to save you money on your energy bill.  The difficult decision in investing in these technologies is that you are essentially locking-in the technology at a higher up-front cost, on the "promise" of monthly energy savings over the next 15-20 years.  When you factor in the financing costs of the extra up-front investment, rarely will you see any real economic savings.  What's worse, you've take on more technical and obsolensence risk in the locked-in technology and forever forego any advancements in technology. 

You have essentially prepaid for all of your presumed energy savings - without any guarantee those savings will be realized.  The same analysis should be applied to your foundation wall. 

SPX costs less than traditional construcution (i.e. poured concrete with 2x4 interior framed walls) or ICF walls, yet delivers improved thermal performance, and adds more value from the increased living space.

Canada Housing & Mortgage Corp Study Shows that ICF isn't worth the added costs.

CMHC commissioned this study to update the economic assessment of residential basement insulation options to more accurately reflect the rising costs of basement construction and space-heating energy.  An ICF basement adds over 35% extra cost to the installation, but only delivers a mere $10 per year savings on heat.  ICF will cost you over $7500 additional lifecycle cost.
