Not so long ago, if we wanted to compare the energy efficiency of different wall build-ups, ceiling build-ups, roof build-ups and materials, we had to build several homes and measure outcomes over time - using mechanical tools. Not any more. This "Virtual" building science exercise takes a modern farm house floorplan as its template, and applies computer wizardry.
Our friends at Dietrich's 3D-CAD/CAM Software used their sophisticated digital tools to simulate how various envelope build-ups would change the overall energy performance of this home. In this article, you'll find some intriguing insight into the pros and cons of various wall systems.
