U-Anchor in 150 MPH Wind Zone
ANNA MARIA ISLAND, Florida – The U-Anchor, U2000™ was recently installed on the rooftop of the newly completed LEED registered building within the sustainably designed and built Anna Maria Historic Green Village.
The U2000 supports a solar racking system holding 42 Photovoltaic panels anticipated to produce 11 KW of electricity. The mixed-use Net-Zero Energy Anna Maria Island project resides along one of Florida’s hurricane-prone tourist destinations at the Gulf of Mexico beach, where local codes require building materials to pass 150 mph wind load testing before they can be installed.
Third-party independent testing found the U2000 to have approximately 1,800 lbs of ultimate load capacity, and the rooftop attachment product can perform in conditions that exceed hurricane force winds due to its high tensile strength and shear strength. The test was conducted according to the ASCE 7-10 ASTM E330-02 (2010) TAS 1178 standards. The U2000 rooftop attachments were installed in Anna Maria Island with a hot air welder on the building’s 1,000 square foot fully-adhere low-slope white membrane roof without requiring any penetrations of the TPO membrane and without the need for any ballast on the solar racking system.
The U2000 can save time and money compared to traditional solar mounting attachment methods and can be quickly installed at a rate of 12 per man hour. Solar integrator, Region Solar of Sarasota and New England, oversaw the installation of the U2000, which was also utilized to mount a rooftop copper-glass panel for solar thermal hot water heating.
“The benefit to the U2000 is you are not penetrating the roof,” said solar integrator Andrew Tanner of Region Solar. A roof pre-design meeting early in the project was held between the roofing contractor and Tanner to design the support structure for the flex needed in a high wind area with a TPO roof membrane. This enabled Tanner to utilize the U2000. The U2000 consists of an encapsulated weatherized steel plate with a 3/8 inch by 1.5 inch tall stainless steel stud, which has been heat fused to a 15.75 inch by 15.75 inch (40 cm by 40 cm) thermoplastic (PVC or TPO roofing membrane) target. A second 11 ¼ inch cover is welded to the bottom target to cover the steel plate. The U2000 attachment is designed to be installed without fasteners.
The newly constructed building at 507 Pine Avenue will be used for residential units on the second-story and a bakery in the storefront at street level. The project is anticipated to gain LEED Platinum certification from the U.S. Green Building Council (USGBC). The other buildings in the historic village were designed and built to be Net-Zero Energy and they have received USGBC’s LEED Platinum certification.
The Anna Maria Historic Green Village is a development of Mike and Lizzie Thrasher, who have spent the past eight years restoring several historic island cottages, moving and grouping them together, and then modernizing them with renewable and green energy systems. The Thrashers also worked with local entrepreneurs to create and locate their businesses in the cottages and other commercial buildings – all while preserving the Old Florida charm of the 100-year-old Gulf Coast island city.
