The question should be can you afford not to with the rising cost of energy. This step-by-step Energy Savings Analysis allows you to fully evaluate how BuildBlock saves you money. We encourage you to print out this page and do the math! You’ll discover you can afford to build with BuildBlock. In fact, you can’t afford not to build with ICFs!

1. Determine Your Utility Costs Savings

With BuildBlock, your savings begin with your utility bills:

Average Utility Cost Per Sq. Ft.
Concrete Block Home	.10¢ to .13¢ per month
Wood Frame Home*	.08¢ to .12¢ per month
BuildBlock ICF Home	.03¢ to .04¢ per month

NOTE: The utility costs will vary depending on your climate zone. The utility cost quoted above is for Florida. If you live elsewhere, call your local utility company and ask them for the average utility cost per square foot for your area. Then substitute that figure for the 8-12¢ figure above. The utility cost quoted for an ICF home will be the same regardless of where you live.

2. Follow these instructions for the chart below.

Line A: Input the size of home you plan to build. Multiply it by 0.08 (8¢) which is the lowest concrete block utility cost per sq. ft. This gives you the average monthly utility costs for a concrete block home that size.

Line B: Input the size of home you plan to build. Multiply it by 0.04 (4¢) which is the highest ICF utility cost per sq. ft. This gives you the average monthly utility costs for a BuildBlock home that size.

Line C: The difference between Figure A and Figure B is the amount of money you’ll save every month in utility costs for as long as you own your BuildBlock home!

Line D: Simply multiply that figure by 12 to see how much you’ll save each year.

Here’s an example chart, based on building a 2,600 sq. ft. home in Florida:

A.	#Sq. Ft. 2,600	x 0.08 =	$208 Concrete Block
B.	#Sq. Ft. 2,600	x 0.04 =	$104 ICF's
C.	Savings Per Month (A minus B)		$104
D.	Savings Per Year (C x 12 mos)		$1,248

A.	#Sq. Ft.	x 0.08 =	Concrete Block
B.	#Sq. Ft.	x 0.04 =	ICF's
C.	Savings Per Month (A minus B)
D.	Savings Per Year (C x 12 mos)

Your Savings Don’t Stop There!

Now that you’ve established your monthly and annual utility savings, let’s look at how you can use these savings to eliminate literally thousands of dollars in interest on your home mortgage.

Notice that your utility savings (Line C above) is $104 per month.

Apply your $1,248 annual utility savings to the cost of your walls and you will see on our Concrete Block to ICF Price Comparison after approximately 7 3/4 years, the wall construction cost is “paid off”.
If you continue to apply your monthly utility savings to your house payment you will trim years of payments and thousands of dollars in interest off your mortgage!
