Hurricane Restoration and Planning for the Next One

Condominum complex damaged in hurricane argues for resilient design solutions to mitigate damage from storm winds.

Hurricane force winds are relentless and, as we’ve learned, they do not differentiate or discriminate. Any structure in the storm’s path may be at risk, and while no building is entirely safe, some are more resistant to damage than others due to resilient design and construction. So, in the aftermath of a devastating storm, it behooves property owners to carefully assess damaged structures and consider restoration and repairs that will mitigate future storm damage. Whether the plan is to repair, restore or rebuild a storm-ravaged building, there are many solutions today that can help withstand high winds and water damage in the future. In many cases, a relatively small up-front investment can result in big future savings based on losses avoided. The weather’s not getting better, but builders are getting smarter Hurricane protection used to be limited to building on pillars to elevate a structure above the flood zones, using wind-resistant concrete block construction and putting up hurricane shutters. Well, we’re a long way from Kansas Toto, and the art of hurricane protection for the built environment has come a long way since then. New high-performance materials and components and improved construction methods offer much greater resistance to the forces of nature that cause damage. Builders who adopt the best technology for resilient construction and restoration — before and after a hurricane — can help ensure that commercial structures better withstand nature’s fury Today’s state-of-the-art building materials can help fortify structures against hurricane hazards: winds, flying debris, and flooding from rain or storm surges. Cost-effective, hurricane-resistant building materials and technology do exist and can help the built environment withstand these extreme weather events. When windows burst from high winds, buildings can pressurize as wind rushes in, popping off the roof. New roof attachment methods can add strength, and spray-foam adhesives (which are applied on the inside of the house’s roof and double as insulation) are rated for higher wind speeds. To deal with flooding, hydrostatic vents can allow water into the home but stop floodwaters from accumulating, potentially degrading its walls and foundation. A few basic structural upgrades can make for improved performance and help keep coastal structures safe including: properly designed footings, pilings and flow-through designs, a continuous load path to resist wind uplift; strong lateral bracing (or engineered shear walls) to resist the sideways pressure of wind; hardened or protected windows and doors to resist penetration by wind-borne debris. There are also exterior cladding options to protect against storm winds, water intrusion, and wind-borne debris — the leading causes of building envelope failure in hurricanes. Most of these systems can be installed economically on a variety of construction types, including metal frame with gypsum sheathing, wood or steel […]


Restoration of Iconic Buildings Means Big Business and Big Energy Savings

The Transamerica Pyramid in San Francisco is one of many older, iconic buildings that are benefiting from retrofitting and restoration.

As reported by National Geographic this month, iconic buildings are often celebrated for their architecture that has withstood the test of time, but what lies beneath those favorite, enduring facades – the cladding and infrastructure — does not usually hold up so well. The majority of the world’s most famous structures were built long before sustainability, climate change, recycling and energy efficiency were key trends and mainstream buzz words. Enter the age of retrofit and restoration, which has (thankfully!) become the prevailing practice in preserving vintage structures worldwide. Aging buildings of note are being updated with new windows and claddings, lighting, heating and cooling systems, all of which are preserving the historic nature of the buildings, saving owners and operators money while also conserving energy. Some iconic structures that have set an example for others to follow include the Empire State Building in New York, the Eiffel Tower in Paris, the Sydney Opera House in Australia, the Reichstag in Berlin and the Transamerica Pyramid in San Francisco. The Depression-era Empire State Building completed a $13 million energy-efficient retrofit in 2013 that cut energy consumption by almost 40%, saving over $4 million annually. The upgrades are expected to eliminate105,000 metric tons of CO2 emissions over 15 years. In keeping with its original raison d’etre as a symbol of engineering prowess, the Eiffel Tower undertook a 4-year, $37 million renovation, completed in 2015. It included everything from installing solar panels to LED lighting, and adding enhanced glazing on glass. In addition to saving energy, the structure now generates much of its own electricity with wind-powered turbines in the building. The 853-foot Transamerica Pyramid, built in 1972, was the tallest building in San Francisco until it was eclipsed last year by the 1,070-foot Salesforce Tower. But it’s keeping up with the newer structure thanks to a sustainability retrofit and a gas-fueled cogeneration plant in its garage that generates 70% of the building’s electricity. In 2011, the Pyramid was certified LEED Platinum, the country’s highest rating for green buildings. Revitalizing iconic buildings is only a small part of the huge commercial market for restoration and energy efficient retrofitting. New York, for instance, is also tackling the improvement of energy efficiency in less prominent landmarks, investing nearly $500 million to improve its million-plus buildings. Buildings consume 73 percent of the electricity in the U.S., and indirectly create 38 percent of carbon dioxide emissions—more than industry or transportation. Experts estimate that only 10% of the 5.6 million commercial buildings in the U.S. are now “high performance” thanks to upgrades. The remaining 90% represent a huge market opportunity. Leaders in the building material and restoration industry such as Sto Corp. have been on the forefront of commercial […]


Sto Helps Transform Affordable Housing Complex

Sto was instrumental in helping to restore the Georgia King Village residential towers in Newark, New Jersey.

Built in 1976, Georgia King Village in Newark, New Jersey, was in need of a makeover.  L+M Development Partners who acquired the two 18-story, affordable housing towers in 2016, were taking on a distressed structure, but were confident they could restore the complex. One rehab priority was installing a new exterior to replace the uninsulated precast concrete façade; the envelope was so porous that Georgia King residents were consistently unable to maintain a comfortable temperature in their apartments. Over the next few years, L+M Development added a fresh new design and structural improvements transforming the Georgia King Village into a more efficient, more comfortable, and more attractive complex, while preserving its affordability. Working with Sto Corp. products and experts, L&M upgraded the towers’ building envelope, using StoTherm® ci Essence, a system that combines the quality of StoTherm® technology with a StoGuard® waterproof air barrier incorporating air, water, and vapor control layers and protection against moisture intrusion. Sto TurboStick®, a relatively new product, was also used to improve the speed and efficiency of installation.  The product is a ready-to-use, single component polyurethane foam adhesive for securing Sto Insulation boards in StoTherm exterior wall claddings. It helps workers install the boards faster and easier than traditional adhesives. “We wanted to bring high-end products like the StoTherm system to this project so we could make a positive difference for the people who live there by improving their comfort as well as enhancing the appearance of the towers,” said Elli Himelstein, Project Manager with L+M Development With eight facades, multiple drops and a difficult design pattern to follow, it was a challenging, project. Nonetheless, Georgia King Village residents were able to remain in their apartments for the duration of all these improvements. Their lives were not disrupted to accomplish the upgrade. In addition to the high-caliber products provided, Sto also worked with the property management team to mitigate any resident concerns. A technical representative from Sto Corp. was actually dispatched onsite to explain the re-cladding system and construction process. By walking residents through the installment timeline, which included a vision of the final result, they explained that ultimately the system would be more energy efficient, and their homes would be more comfortable and attractive. The makeover marks the official re-emergence of the residential complex as a symbolic cornerstone in Newark’s West Ward. Today, the positive changes continue, and the adjacent community has a new vitality.  In fact, the McDonald’s restaurant adjacent to Georgia King Village recently renewed its façade and landscaping, and when choosing the exterior wall color, asked L+M for the shade they had used for their renewal project.  The multi-national restaurant chain liked it so much that they matched the Georgia King façade’s gray for their […]
