Making Energy Efficiency Attractive
In chapter 4 of the 2009 to 2018 International Energy Conservation Code states that there is 3 ways to achieve code approval of the building envelope. First is the prescriptive R-value for in the IRC codes. Second is a trade-off method which is where the REScheck program used to be used. In 2009, the DOE took most of the trade-offs out of the program and most just resort to the prescriptive approach,
Third is the performance method which states that if you can provide an energy modeling report that shows that the home will be at least 30% more efficient than traditional building method then it's approved.
Here is an example of a home in Alabama and it exceed that performance standard by 15.6% (meaning that it is actually 45.6% more efficient)
In this example: It shows that Spray Foam Insulation will out-perform traditional fibrous insulation at a greatly reduced R-value.
Spray Foam Insulation has a Diminishing Rates of Return on its efficiency. Generally speaking, an R-20 of Spray Polyurethane Foam will provide a 96% heat flow reduction. If that thickness is doubled to achieve an R-40.... we only jump to a heat flow reduction of 97.5%
This increase of 1.5% will double your cost of the insulation and only save you a couple dollars in energy per month.... That equates to a ROI in the hundred+ year range.
Now you can see why More does NOT equate to More Savings!
You know how well your products work and you do your best to relay that message to your customers but they may not completely understand or believe you. Now you can use an EMA comparison report to prove the future performance of that new home. We recommend that you get this report done before you go and meet the builder or homeowner and use it as a sales tool. We have many insulators with a closing ratio of over 80%... just by showing the customer why they need to invest in Spray Foam Insulation. See the attached video to learn how to make this work for you too!

High performance insulation like Spray Foam works by Air Sealing a building. A tight house requires fresh air make-up. In fact, the 2012 IECC codes require an ERV or HRV system to be installed for buildings with an Air Infiltration Rate of less than 0.30 ACH/Hr at 50 Pascals.
It is very important to work with the HVAC contractor to right-size the system using a version of the Manual J software. If the HVAC contractor does not have this software, please encourage them to visit this website and choose the HVAC button. We can help with that too.
With a tight house, right-sizing usually means downsizing by at least a third. An A/C system has 2 duties. It's naturally meant to cool but it also pulls moisture out of the air. If it is oversized, it will short cycles (reduces the lifespan of the system) and not run long enough to pull the moisture out... causing cold clammy areas and a potential for excess moisture buildup.
How can I show the efficiency of my high-performance insulating products?
How can I compete with the cheap cost of fibrous insulation?
I know it doesn't pay to install high-performance insulation to the prescriptive building code requirements.... How can I show code compliance while installing a lesser R-value?
