Author name:  Peter Yost Blog Category:  BuildingGreen's Top Stories WUFI doesn’t kill buildings. Poor design, specification, and workmanship kill buildings. Last year, BuildingGreen made a modeling software program one of our Top-10 Green Building Products for the first time—the WUFI hygrothermal modeling software from Fraunhofer IBP and Oak Ridge National Laboratory (see “ Using WUFI to Prevent Moisture Problems ,” an EBN building science primer). We did this because managing moisture as intensely as we manage energy is key to building durability and indoor air quality ( IAQ ). But after taking the two-day WUFI training and working with WUFI PRO 5.2 for a while, I began worrying about just how much I might be misusing or abusing this powerful and complex modeling tool. I thought it made sense to reduce that worry by taking Building Science Corporation’s Advanced WUFI one-day workshop. I would like to tell you that today I am less worried about myself and other dilettante users of WUFI—but frankly, I am now more worried than ever. That’s because, as with any modeling software, getting something wrong in WUFI can lead to wasted materials and money. It’s one thing to use more energy than you expected, though, and quite another to have your building quietly rotting from the inside out. Getting something wrong hygrothermally can be devastating in terms of overall building durability. read more
