Pacific Northwest National Laboratory (PNNL) has completed a study on the effect that various wall systems have on the annual energy usage in one- and two-story residential homes.
The study’s objective was to obtain a direct comparison of the actual energy and dollars expended using different types of walls in a typical residential home while keeping all other aspects of the house EXACTLY the same. This research was done using EnergyPlus™, a simulation software developed by the Department of Energy and acknowledged as one of the most accurate and powerful energy simulation tools available today.
The results are groundbreaking in the breadth and scope of the walls compared - 607 different combinations of CMU, wood and ICF. Almost every conceivable arrangement of standard building products compared “apples to apples” across every climate zone in Florida and the US. A total of 21,852 separate wall system analyses were made. Of these, 3,642 wall system analyses were made specifically for Florida.

Huge for our industry, especially in North Florida. Definitely not what the wood frame home builders have been saying and a huge tool for talking to the end user, the decision maker and home buyer. As I remember, things did not work out so well for the pig in the wood house, and now we have energy data to make it an even better issue.
