Florida International University researchers and their collaborators are, quite literally, trying to blow the house down. A full-scale manufactured home has been bolted in front of FIU’s Wall of Wind and hit with hurricane-strength gusts so scientists can watch exactly how it starts to fail. The month-long testing campaign is aimed at tracking how common anchoring and installation methods perform as wind speeds climb and at generating hard data engineers can use to push for safer installation practices. Teams say the results could eventually shape long-term changes to the federal rules that govern factory-built housing.
Testing the home with Category 5 gusts
For the first controlled run, officials started at about 110 mph, with plans to step up to 130 mph and then 150 mph in later rounds, according to NBC 6 South Florida. Cameras surround the test bed, capturing the moment skirting, siding and anchors begin to give way as pressure builds. Researchers are especially interested in sequences of failure that are almost impossible to spot in small-scale or low-speed lab work.
The research effort and what they’ll measure
The campaign is part of the multi-institution WE WiSH project, led by the University of Kansas and scheduled to run into early June. The KU-led group has 18 wind tests planned across three different manufactured-home specimens. As outlined by the University of Kansas, the team will change variables such as anchorage level, crawlspace skirting, elevation and wind approach angle to document how the homes fail, validate engineering models and put numbers on how installation choices affect survivability. Project leaders stress that full-scale, outdoor testing lets crews install anchors in real soil, which they say is critical for capturing how the systems actually behave under extreme wind loads.
Meet the Wall of Wind
FIU’s Wall of Wind is a 12-fan, full-scale hurricane simulator that can generate Category 5 wind speeds, roughly 157 mph at maximum power, as detailed by FIU News. The setup can pair those winds with driven rain and has been used for years to test roofs, windows and other building systems. Researchers say that scale is what lets them set manufactured homes on realistic supports and then watch in real time how anchors, piers and the rest of the system handle the punishment. Recent federal funding has expanded the lab’s testing capacity and its ability to probe extreme scenarios that can eventually drive changes to building codes and products.
Why manufactured homes are a focus
Project organizers point out that millions of Americans live in HUD-coded manufactured homes and that those residents are often among the first asked to evacuate when a hurricane watch or warning is issued, according to NBC 6 South Florida. A project release cited in local coverage noted that manufactured homes "still make up more than eight percent of the nation’s housing stock," while federal research groups and housing analysts put the share of occupied units in the single digits and offer more detailed breakdowns of shipments and overall stock. The Urban Institute provides a recent review of manufactured housing’s role in the broader national supply. Because manufactured homes disproportionately serve lower-income households, researchers argue that stronger installation rules could play a major role in cutting storm-driven displacement.
Next steps and how to follow the tests
The WE WiSH team plans to release interim findings and use the experimental data to validate finite-element models, then translate those insights into recommendations for HUD and other code-setting bodies, per the University of Kansas. KU’s project page also offers background resources and a signup for livestreamed test updates for interested members of the public and industry stakeholders. Researchers caution that any formal change to HUD’s federal standards would still require years of committee review and rulemaking, but they describe these full-scale wind tests as a necessary early move toward tougher, more resilient installation practices for manufactured homes.
