The LSU AgCenter's "LaHouse" is designed to stand up to hurricane-force winds, swarming insects and harmful humidity. This family-type home is designed to showcase innovations in home construction for Louisiana’s sub-tropical climate.
This house, completed in May 2008, is one in a series of prototypes designed and built by Tulane University's URBANbuild. This house meets the new 3-feet advisory base flood elevation, and is built for 140 mph winds, which exceeds the wind-resistance requirements of the state uniform construction codes for this area.
LaHouse has a flood protection level 3 feet above Base Flood Elevation, using three elevated foundations on the house and dry-floodproofingon the non-residential building (garage/classroom). Wind and moisture protection are also addressed.
LaHouse showcases four types of construction: Standard 2 x 4 Framing, Advanced 2 x 6 Framing, Structural Insulated Panel Systems (SIPS) and Insulating Concrete Forms (ICF).
LaHouse has several features for flood and wind and water resistance that are not captured in the building component descriptions. These include a Safe Room, Dry Floodproofing, anchoring of the flat roof of the breezeway, porct protection and closets, ground sloping away from the foundation, back-flow protection and elevated utility systems.
The roofs at LaHouse are predominantly hip-style for greatest wind resistance. Both metal and simulated clay tile are demonstrated with high-wind installation.
Windows and doors at LaHouse are selected and sized to meet the cojde-specified design pressure rating for a 130 mph wind zone. Where windows and doors are not impact rated units, they are protected by shutter, panels or screens. Windows and doors are flashed so water drains to the outside, not into the wall cavity.
Walls at LaHouse are wind and water resistant. Sheathing and hardware contribute to shear, lateral and uplift resistance. Layering and taping of housewraps and flashings provide resistance to water and moisture penetration. Drainage planes exclude water that penerates exterior finishes.
