There is a demonstratable link between humidity and the infectivity and longevity of a variety of viruses, such as influenza and coronaviruses, according to a new whitepaper by Munters, a globally renowned company in energy-efficient and sustainable air treatment solutions. Titled ‘How Humidity Control Can Reduce Viral Infectivity and Longevity’, the scientific report addresses how it is possible to reduce the transmission and longevity of harmful viruses by controlling indoor Relative Humidity (RH) levels. ‘How Humidity Control Can Reduce Viral Infectivity’ The paper is based on gathered research, including studies on the efficiency of respiratory droplet transmission at humidity and temperature, virus survival and transmission at absolute humidity levels, and the effect of environmental parameters on the survival of airborne infectious agents. Among the most notable and timely findings, the research demonstrates that at RH levels between 40 and 50%, many types of common and harmful viruses such as influenza and coronaviruses are rendered inert much more quickly than at RH levels of less than 20%. “Viruses that cause respiratory illnesses are often transmitted by viral particles through coughing, sneezing, talking and breathing,” said Martin Ginty, Global Pharmaceutical Industry Manager for Munters. Controlling indoor Relative Humidity (RH) levels By effectively controlling indoor climates, it is possible to limit the transmission of harmful viruses" Martin adds, “Research referenced in our whitepaper suggests that maintaining an indoor RH% level between 40 and 50% yields the maximum protective effect from both aerosolized and settled virus particles and that by maintaining these levels, it is possible to contribute to a healthier, safer environment.” “This evidence is particularly relevant in locations where winter tends to consist of low outdoor temperatures and low indoor humidity, as these conditions offer a favorable environment for viral transmission,” added Ginty. Martin further said, “By effectively controlling indoor climates in these locations, it is possible to limit the transmission of harmful viruses.” Maintaining target RH levels Maintaining target RH levels can be accomplished using humidity control solutions which facilitate precise RH control for indoor environments. Furthermore, the whitepaper concludes that humidity control is always useful, but particularly during a typical ‘flu season,’ where outdoor temperatures and absolute humidity tend to be lower.

Thin Air Energy, a globally renowned provider of energy storage and LED lighting technology solutions, has announced two new breakthrough products in the COVID-19 era. The first product is TORCH UVc, a germicidal, anti-viral product that emits ultraviolet light in the UVc spectrum, where germs and viruses are killed. Germicidal and anti-viral products It has a novel feature, which is believed to substantially increase germ killing effectiveness. The second product is GEIGER UVc, which is a device used for measuring the instant intensity of UVc and accumulated dosing of UVc radiation. "Thin Air Energy is at the forefront of germicidal and anti-viral products for home and office use," said James Wiebe, CEO of Thin Air Energy, adding "These two new products provide an enormous benefit to the user, along with a simple way to measure the field strength and dose of UVc radiation." TORCH UVc TORCH UVc features a patent pending mode of operation, which modulates the UVc output TORCH UVc features a patent pending mode of operation, which modulates the UVc output in such a way that the efficacy may be substantially improved. This special enhanced kill feature of TORCH UVc may be enabled or disabled as desired by the user. If disabled, the product emits a conventional, continuous output of UVc. The product is designed with solid state LEDs and is not tube based. Consequently, the product will also last longer. TORCH UVc also includes another patent pending feature, a very bright white LED light, which flashes and alerts the user that the product is turned on and is potentially dangerous. This feature is more effective than the soft purple glow that many UVc devices emit. The flashing white LED light actively discourages users from looking into the UVc output. GEIGER UVc The GEIGER UVc allows users to easily measure the field strength of UVc radiation. GEIGER UVc measures the field strength of only UVc, ignoring UVa and UVb (which are commonly used in tanning salons and resin curing lights, and also potentially in fake UVc devices). GEIGER UVc also has great resistance to visible light as well. GEIGER UVc is the size of a key fob, and in addition to showing continuous UVc field strength (in milliwatts), it also measures the cumulative dosing, providing an LED alarm indication when 5,000 millijoules and then 30,000 millijoules of radiation have been detected. These dosing levels reflect dosing known to be effective for disinfection from published literature for certain germs and viruses. When the dosing level is achieved, a LED on GEIGER UVc turns on. Intensive R&D in product development Both products were designed with careful attention to a large number of published papers, including research and development that shows the improved germicidal efficacy of UVc when appropriately modulated. Our products are designed with science and are patent pending, state of the art, with improved safety and efficacy" "The internet is already filled with stories of fake UVc light sources that inadequately kill germs," James Wiebe said. He adds, "Social media is a plethora of cheap, featureless UVc devices of unknown strength and quality. Our products, in contrast, are designed with science and are patent pending, state of the art, with improved safety and efficacy." Products availability These products are available for pre-order on the official Thin Air Energy company website and through additional retailers in the coming months. The cost of raw UVc LEDS is rapidly rising in the current COVID-19 pandemic scenario, with prices being subject to change without notice.
HVAC systems are the most common home repair, representing 19 percent of service incidents facing homeowners. More than half of homeowners (53%) have faced a home repair emergency of some kind in the past 12 months. Furthermore, about a third of homeowners have US$ 500 or less set aside to pay for emergency home repairs, with some 17 percent having no money at all set aside for emergency home repair work. 10th Edition of the Biannual State of the Home Survey These are among the results of the 10th Edition of the Biannual State of the Home Survey conducted by The Harris Poll on behalf of HomeServe USA Corp., a provider of home repair solutions in the U.S. and Canada. The survey carried out covered 2,026 U.S. adults (of which 1,454 are US homeowners) was conducted during the early days of the COVID-19 pandemic lockdown. HomeServe’s real-time repair data shows that customers are continuing to require urgent repair help during the COVID-19 pandemic period. Greater strain on home infrastructure and HVAC systems More Americans are putting extra strain on their homes’ infrastructure and major systems More Americans are putting extra strain on their homes’ infrastructure and major systems. As parents are spending more time working from home, and the children are in home schools, the shortcomings of existing systems are becoming more obvious, especially as the summer temperatures rise. In the current uncertain times, comfort is more of a need than a luxury. Concerns about air quality in the wake of the COVID-19 pandemic, which is occurring at the height of the allergy season, are also driving new business for HVAC technicians. Technicians using personal protective gear at homes Service technicians are using proper social distancing protocols and personal protective gear (PPE) while performing maintenance and service tasks at consumers’ homes. Consumers want to know what companies are doing differently to protect their customers during the pandemic. At the very least, installers should keep contact to a minimum and meet Centers for Disease Control and Prevention (CDC) and state and local requirements to contain the spread of the coronavirus. Following social distancing protocols in repair works “We’re wearing gloves, washing our hands between calls, wearing masks, and we have sanitizers and soaps in our cars, making sure we are maintaining safety,” said Michael Concannon, Repair Technician for Bell Brothers, located in Sacramento, California, USA. There is also an opportunity for HVAC companies to provide expert advice on subjects that customers are asking about now, such as indoor air quality. In the midst of economic uncertainty, routine maintenance can provide greater peace of mind, as well as extend the life of equipment. Consumers to foot bill for home repair work According to the HomeServe survey, many homeowners do not know it is their responsibility to pay for home repairs According to the HomeServe survey, many homeowners, especially younger ones, do not understand that it is their responsibility to pay for home repairs. Many mistakenly believe repairs will be covered by a city/municipality, a water utility, or a homeowner’s insurance. “The findings of the latest survey clearly show that homeowners, especially younger ones, are unaware of their responsibility when it comes to common home repairs,” said John Kitzie, HomeServe USA Chief Executive Officer (CEO). Smart financial planning tools John adds, “HomeServe seeks to educate homeowners and to provide them with smart financial planning tools so they are prepared when an inevitable home emergency strikes.” HomeServe USA serves more than 4.4 million customers across the U.S. and Canada under the HomeServe, Home Emergency Insurance Solutions, Service Line Warranties of America (SLWA) and Service Line Warranties of Canada (SLWC).
Newer buildings tend to be designed to be ‘green’, but what about older existing buildings, which still represent the largest share of environmental impact? There is more work to be done in the retrofit sector; and improving environmental performance of older buildings often involves ‘deep retrofits’ that are costly and impact multiple factors inside a building. In the COVID-19 era, there is also growing concern about needs such as circulating outside air, increasing humidity, and improving filtration systems even as older buildings seek to become greener. The consistent theme is a need to work toward better-designed, more energy efficient and healthier buildings. Healthier Buildings for a Greener Future If you layer infrastructure issues with the new health challenges, it raises the issue to a higher level" “If you layer infrastructure issues with the new health challenges, it raises the issue to a higher level,” said Tony Cupido, Research Chair, Sustainability at Mohawk College, adding “You will see a greater need to provide health and wellness as we move forward.” Cupido was among the panelists at a ‘Healthier Buildings for a Greener Future’ Virtual Summit sponsored by Armstrong Fluid Technology. The discussion centered around the various aspects of “deep retrofits,” how to pay for such improvements and how to measure success. Balancing health features with energy-efficiency Achieving healthy and green buildings might involve working at cross purposes. “When we think about healthy buildings, we are seeing recommendations that tend to increase the energy needs of the buildings,” said Marta Schantz, Senior Vice President, Greenprint Center for Building Performance, Urban Land Institute, adding “For example, a better filtration system might require a more powerful motor to offset the added drag.” “In order to be both healthy and energy efficient, there are creative strategies,” said Schantz, adding “We should be thoughtful about how sensors and other technologies can address the challenge of balancing healthy features with energy-efficient features.” Deep retrofits “Deep retrofits are more complex from an engineering standpoint, especially when compared to other green issues such as LED lighting. Paving the way for more deep retrofits can include reining in that complexity by creating prefabricated or ‘canned’ solutions that are easier to implement,” said Peter Thomsen, Director/Global – Building System Solutions, Armstrong Fluid Technology. An obstacle to deep retrofits is lack of information about what technologies are available. “You don’t know what you don’t know,” said Schantz. The second obstacle is financing. One approach is to ‘bundle’ multiple projects to improve building performance, such as combining a fast-payback project (e.g., lighting) with a longer- (and larger-) payback project such as an air handling system. Another approach is to create pay-as-you-go models and/or ‘energy efficiency as a service’ plans that help to make the expenditures and budgeting more manageable. A step-by-step approach can achieve energy savings that will pay for each successive step. Efficiency of Building management systems Occupants of buildings today have a better understanding and are more informed through better technology" New metering, intelligence and transparency capabilities of building management systems can yield metrics and measurable results that can drive return-on-investment (ROI) considerations. Metrics also drive useful comparisons with other buildings in the same peer group, thus inspiring best practices to achieve better results compared to buildings of the same size and type. “Occupants of buildings today have a better understanding and are more informed through better technology,” said Cupido, adding “It will become even better over time as AI (artificial intelligence) looks at the pieces and fixes it themselves.” Widening scope of AI integration Better understanding equates to more buy-in by building occupants. “They are not only becoming more informed, but are more likely to buy into the technology,” said Schantz, adding “The long-term success depends on it. Everyone needs to be bought into the technologies to ensure long-term success, both on the health and wellness side, and the energy efficiency side.” A holistic approach is needed when planning deep retrofits, and care should be taken to ‘right-size’ the equipment by taking into account design changes that can lower system requirements. Advent of new building systems Designers should resist the temptation to ‘bulk up’ systems to exceed minimum requirements. For example, when specifying a rooftop unit, engineers should factor in any efficiency gains they have achieved by using tighter windows, LED lighting or other factors. Building owners face a learning curve in relation to new systems" “The idea is that you don’t replace it directly, but right-size it to the new requirements,” said Schantz, adding “Building owners face a learning curve in relation to new systems, and new building systems are “almost like a computer. It’s no longer a case of just turning building systems on and off. There is a risk that the building operations team does not know how to run the equipment.” Avoiding data overload Schantz further said, “Technology will not run as intended if it is not operated properly. It loses some of its value. The building operations staff needs to stay up to date and know how to operate the equipment. Peter Thomsen concludes, “One pitfall is to overwhelm building operators with too much data. “Data overload is too much and, as leaders, we need to avoid that.”
The American Innovation and Manufacturing (AIM) Act of 2019 would provide an orderly national framework to guide replacement of hydrofluorocarbons (HFCs) over the next several years in the United States, with newer refrigerants that have less negative impact on the environment. HFCs are potent greenhouse gases with very high global warming potential. The future of the HVAC industry is tied to the manufacture of next-generation refrigerants and their adoption. Versions of the AIM Act – Senate bill S.2754 and House bill H.R.5544 – are currently in the Senate Environment and Public Works and the House Energy and Commerce committees. The global market is moving away from the use of HFC refrigerants, given that the Kigali Amendment to the Montreal Protocol requires their phaseout; however, the United States has not ratified the Kigali Amendment. Over the next 15 years, the AIM Act would phase down HFC to a low of 15% of current production and consumption levels. In addition, aftermarket supplies from recovery, recycling and reclaiming would ensure adequate availability of the refrigerants for use in legacy systems and in applications for which substitutes are not available. Economic Stimulus For The U.S. HVACR Industry The Air-Conditioning, Heating and Refrigeration Institute (AHRI) contends passing the act would “serve as a potent form of economic stimulus for the U.S. HVACR industry,” in addition to providing clarity on the regulatory landscape. The AIM Act would create new manufacturing jobs in the United States, spur HVACR investment in the U.S. economy, and ensure the continued safety and training of licensed HVACR professionals, experts say. Over the next 15 years, the AIM Act would phase down HFC to a low of 15% of current production and consumption levels The Air Conditioning Contractors of America (ACCA) support the federal approach to an HFC phasedown as preferable to a state-by-state approach, urging Congress to include preemption language in the AIM Act that would require states to follow a federal HFC phasedown schedule for the residential HVACR market. Addressing Safety Concerns Safety concerns arise with the introduction of A2L mildly flammable refrigerants as part of the next phase down of HFCs. ACCA says a unified approach across the United States will ensure the introduction of A2L refrigerants is done safely. Commercial and industrial HVAC markets have been using flammable refrigerants for years; however, building codes and safety standards in the residential market do not currently allow their use. ACCA also urges inclusion of language in the AIM Act to strengthen EPA certification programs and restrict the sale of HVACR systems and refrigerants to only trained and certified individuals. “If Congress does not provide the EPA the authority to regulate and implement an HFC phasedown, then the EPA may not be able to implement training and certification programs or restrict the sale of dangerous products to unqualified people,” according to testimony the ACCA submitted to the U.S. Senate Environment and Public Works Committee. Ending "Dumping" The future of the HVAC industry is tied to the manufacture of next-generation refrigerants The AIM Act would also seek to end the practice of “dumping,” in which foreign manufacturers export inferior products to the United States that are priced below the cost of manufacture. The AIM Act would restrict the import of HFCs as part of the production and consumption phasedown. However, the non-profit Competitive Enterprise Institute (CSI) rejects the need for the AIM Act. “The free market provides the best policy answer,” writes Ben Lieberman, CEI Senior Fellow. “Let the new refrigerants and equipment compete with the current ones, rather than favoring one over the other [through legislation].”
As Albert Einstein once said, “We can't solve problems by using the same kind of thinking we used when we created them.” That wisdom has been put into practice in the form of a smarter approach in the way modular schools can be built and used. Pre-fabricated, modular classroom In 2006, the Montgomery County Public Schools in Maryland, in partnership with the Council for Educational Facility Planners (CEFPI), held a national design competition, The Portable Classroom Design Challenge, to create a pre-fabricated, modular classroom unit that was environmentally sustainable, or green. This competition led to eventual development and installation of one of the most uniquely created modular spaces ever conceived, indeed the award winner of the design competition. Triumph Modular of Littleton, Massachusetts, in partnership with ARC/Architectural Resources Cambridge and builder NRB Inc., won the design challenge because of their revolutionary, new modular classroom. Relocatable Green Modular Classroom Relocatable Green Modular Classroom comes designed with many LEED-focused design elements Aptly named the Relocatable Green Modular Classroom, it's also the first modular classroom to be designed with many LEED-focused design elements. “Our goal was to create a high-quality, portable classroom that was green, one with environmentally conscious materials used in its design and operation. The design was smart in the way that it used resources and provided heat, light, unsurpassed acoustics and air quality within the space,” said Cliff Cort, Founder of Triumph Modular. In fact, it’s estimated that the Relocatable Green Modular Classroom performs 56% better, in terms of overall energy costs, than similar, older style modular units that often use almost three times as much of energy as a permanent school building. Wall-mounted heating and cooling equipment Thirty years ago, Bard Manufacturing Co. Ltd began solving the comfort needs of schools across the country by providing wall-mounted heating and cooling equipment. Bard’s products offer a combination of quiet operation, patented ventilation packages, unsurpassed quality and dependability that make them the #1 choice of many school officials. With three, state-of-the-art manufacturing facilities and a global distribution network, Bard’s commitment to quality and product innovation begins with its commitment to research and development. Self-programming energy monitors and green refrigerants With features like self-programming energy monitors, unsurpassed energy efficiency, green refrigerants and the lowest acoustic profile on the market, Bard delivers products that provide tangible solutions for modern school facilities. Already impressed from their previous working experience with Bard, Triumph Modular wanted to incorporate the Quiet Climate 2 into their green modular design. “Building green is good for the environment, good for the wallet and good for the occupants of the building,” said Cliff Cort, adding, “And Bard’s HVAC unit is a big factor in why the Relocatable Green Modular Classroom performs as well as it does.” Green modular design Bard’s HVAC System in the Relocatable Green Modular Classroom Unit contributes to its high energy efficiency According to an independent third party analysis, the green modular design provides a 68% reduction in heating energy and a 49% reduction in cooling energy, most of which can be attributed to Bard Quiet Climate 2. An efficiently designed HVAC system is perhaps the single largest building component that can influence a building’s sustainability. Bard’s HVAC System in the Relocatable Green Modular Classroom Unit contributes significantly to its high energy efficiency and quiet, almost undetectable acoustic profile (37 bBHL) within the classroom. Quiet-Climate 2 heat pump Bard’s Quiet-Climate 2 heat pump is the most innovative wall-mount HVAC equipment ever made. Designed specifically to provide superior energy efficiency and quiet operation in classrooms, the Quiet Climate 2 uses green refrigerants and provides operating sound levels that are 20 to 35 times quieter than a standard wall-mounted heat pump. Bard’s Quiet Climate 2 can provide the following features: Higher energy efficiency and greater comfort through step-capacity technology Unmatched acoustical performance Sound levels vary with applications and construction techniques, but integrated operating sound levels as low as 35 dbA have been achieved when combined with Bard Quiet-Climate acoustical accessories Improved ventilation and Enhanced IAQ Continuous blower operation – without noise – keeping fresh air constantly in the classroom Optional UV lighting which keeps the coils free of bacteria and mold Enhanced filtration capabilities A one-piece factory unit designed for fast installation and easy servicing Additional sound curbing accessories including, an isolation curb and return air and supply air plenums The Carroll School Serving over 75 communities around Lincoln, Massachusetts, The Carroll School was founded in part by Dr. Edwin Cole who wanted to provide a special school for children with language-based learning challenges. The Carroll School supports nearly 300 students, in grades 1 – 8, with a 3.4 student to teacher ratio using multisensory and individualized teaching methods for specific learning needs. Progressive by nature, The Carroll School’s thriving community brings children together in an environment that values their differences and remediates their learning difficulties. “Cliff Cort, a Lincoln resident and friend of the school, approached us with the idea to replace one of our existing modular building with the green modular design,” said Margaret Gebhard, Director of Finance and Operations at The Carroll School, adding “Our existing modular space was not a popular one with either faculty or students due to its poor lighting, sound characteristics and overall appearance.” Occupancy sensors and vestibule The classroom incorporates many unique green components, such as formaldehyde-free, low VOC paints Things changed when teachers, students and administrative personnel moved into the Relocatable Green Modular Classroom for the first time. The classroom incorporates many unique green components, including formaldehyde-free, low VOC paints and coatings that reduce off-gassing, occupancy sensors that conserve energy by turning the lights off, when people come and go, a vestibule that safeguards the inside from inclement weather while buffering outside noise and helps retain heating and controlling levels for its green and virtually silent HVAC system – the Quiet Climate 2. Enhancing schools’ energy efficiency Margaret adds, “The Relocatable Green Modular Classroom is truly amazing and smart to incorporate into any schools modular planning, we’re quickly approaching our original 3 year leasing agreement with Triumph and I see us keeping the Relocatable Green Modular Classroom around for many more years to come.” She further stated, “It has the best lighting, best HVAC system, and is the most energy-efficient building on our campus, which is why it’s also the most coveted space on our campus. Now we can not only say our kids here are special but now they have a truly special and smart environment in which to learn.”

With news of the coronavirus' airborne droplets being able to be neutralized via advanced filtration, Abacus Plumbing, Air Conditioning & Electrical is responding by providing Houston homeowners with state-of-the-art HVAC testing and next-gen products to combat the COVID-19 pandemic surge. As the virus re-surges throughout Texas and parts of America, infectious disease experts are learning that COVID-19 can be contracted by inhaling tiny, invisible particles that hang in stagnant air for hours. HEPA filters and UV light A recent investigation by ABC's Good Morning America (GMA) revealed that a combination of HEPA (High-Efficiency Particulate Air) filters and UV light are homeowners' best defense against the virus droplets. New York Governor, Andrew Cuomo said recently that large malls should be required to install HEPA systems before re-opening. Delta Airlines is also equipping its fleet of aircraft with HEPA filters, while American Airlines said its planes have been using the systems since the 1990s. The licensed HVAC professionals at Abacus Plumbing can inspect current residential systems and suggest a solution from their extensive line of HEPA and UV products. Cleaning air to clear out COVID-19 particles HEPA systems, such as the REME HALO, can remove 99.7% of particles as small as 0.3 microns" "Obviously, cleaning surfaces is still important, but cleaning the air that recirculates through homes and buildings is now a huge focus," Industrial Hygiene Specialist, Nancy McClellan told GMA. “HEPA systems, such as the REME HALO, can remove 99.7% of particles as small as 0.3 microns,” said Dr. Rajat Mittal, a professor studying the dynamics of COVID-19 particles adding, "That is potentially good news, because almost all the droplets that are going to be carrying viruses are all within that range." REME HALO air purification system Abacus Plumbing so trusts the REME HALO that it's installed in the company's own HVAC systems. "To help keep our employees as healthy as possible, Abacus installed the same air filtration equipment in our offices that we install in our customer homes," said Abacus Plumbing Founder & Chief Executive Officer (CEO), Alan O'Neill, adding "In an essential business like ours, we have to do everything possible to help prevent our team members from allergies, germs and viruses. We owe it to our employees to invest in their health, and our customers who depend on us to be ready to serve 24 hours a day.” The HALO purifies the air in homes from the source, the HVAC system. Its patented technology is hospital tested and military approved to reduce allergies, fight odor and kill bacteria, mold and viruses. Ensuring health and safety of Houstonians "We haven't come across anything that it can't handle," said Rene Luna, whose company, The Partner Group, has been selling HALOs to Houston distributors, like Abacus Plumbing, since 2006, adding "It doesn't wait to clean the air in the equipment and it actually cleans your air and your living space. It's by far the leader in the industry." With COVID-19 finding new ways to harm Houstonians, Abacus is ready to help homeowners protect the health and safety of their family by installing the best defense available.

Hess Tower is a 29 story, 844,000 square foot mixed use building containing commercial office, retail and dining space with an adjacent parking garage. It’s located in Houston’s Inner Loop East area adjacent to Discovery Green park, a 12 acre urban green space for outdoor activities, concerts and other entertainment events. Originally named Discovery Tower, it was renamed in 2009 for the Hess Corporation, its current lessee. It was formally completed in 2010 and is Houston’s first downtown LEED Platinum office building. Great functional and architectural feature “Discovery Tower, now known as Hess Tower, was a very challenging project for NOW due to several obstacles. No access to the backside of the majority of the louvers as well as having to deal with multiple penetrations and architectural accent fins as an integral part of the louvers were the most notable.” “Ruskin did an outstanding job in engineering a blind attachment using interlocking aluminum zee clips as well as coordinating louver blade leave outs for both architectural fin attachment and blank off plates for current and future piping penetrations." "Overall the project was a success and the Ruskin louvers added a great functional and architectural feature to this monumental project.” Says Dan Ozuna, Co-owner of NOW Specialties. Protection against rain penetration Being a high-profile building in downtown Houston, the aesthetic design was a critical component to the success of the project. The architectural design incorporated a significant amount of architectural louvers in the lower elevations. The louvers needed to provide HVAC airflow in some areas with protection against rain penetration in storm conditions. Being in a hurricane-prone area, the louvers had to stand up to the high velocity winds that can occur in the area Other areas were to be inactive with blankoff panels on their interior. All louvers, whether active and inactive, needed to have the same exterior appearance with consistent transitions from one area to the next. The louvers required custom fabrication for various features such as pipe penetrations, mitered corners, door openings and decorative architectural fins. Being in a hurricane-prone area, the louvers had to stand up to the high velocity winds that can occur in the area. Providing vital information Additionally, many of the areas of louver installations were inaccessible from the rear which required those louvers to be installed and fastened entirely from the exterior. Ruskin and its sales representative, Steve Bryan of ADW Corporation, partnered with NOW Specialties to successfully complete this LEED ® Platinum Certified project. ADW and NOW provided vital information on field conditions and adjoining construction to Ruskin’s project management team. This enabled the engineers to precisely design the complex louver system and its custom installation details. The louver model selected for this prestigious project was the EME745. Its Wind Driven Rain (WDR) rating as well as its architectural continuous blade design was the perfect product for this demanding application. The two-piece louver construction includes an exterior 4” deep stationary louver with hidden mullions and a rear 3” deep vertical WDR louver that provides excellent weather protection for HVAC intakes. Custom fabrication and installation requirements The louver system is a key element in the building’s form and function The two louvers are factory combined prior to shipment to the jobsite. Integral to the model is a special design for inactive areas. To keep the clean lines of the exterior louver, the 3” louver is replaced with a solid blank-off panel to block weather & humidity. Ruskin’s Geneva, Alabama production facility fabricated the louvers & delivered to the jobsite in coordination with NOW’s installation schedule. Ruskin’s in-house painting facility is state-of-the-art that not only shortens the lead time to the job site, but includes a 20-year standard warranty for painted finishes. For Hess Tower, the louvers were coated with Ruskin’s Pearledize 70 finish (70% Floropolymer) in a custom Meteor Gray pearlescent color. Due to the extensive custom fabrication and installation requirements, a team effort was needed to successfully design, build and supply the louvers. Ruskin's louver system is a key element in the Hess Tower building’s form and function. With innovative products, comprehensive project design and management services and quality in fabrication, Ruskin is prepared to tackle any architectural challenge.
To improve access into the Four Queens Hotel and Casino in Las Vegas, Four Queens recently added a 48 foot air curtain. Built using Ruskin’s IAQ50 air flow measuring and control dampers, the new air curtain efficiently and economically maintains the pressure in the building. Designed to satisfy the needs of a variety of applications, the IAQ50 air flow measuring and control damper provides the perfect solution to difficult challenges. Downtown Las Vegas hasn’t been the same since the completion of the Fremont Street Experience revived this popular gambling and tourist destination. This four-block project has successfully turned a city street into a large canopy-covered walkway that has substantially increased the tourist and gambling business in the downtown area. Mist evaporation system The Fremont Street Experience which includes a mist evaporation system to protect the tourists from the sun and heat, and a laser light show presented several times nightly, created problems for the Four Queens Hotel and Casino. Business at the Four Queens Hotel and Casino, located on Fremont Street, was suffering because the two existing air curtains on each end of the casino were limiting access into the hotel and casino from the sidewalk where the crowds stroll and gather to watch the light shows. In order to share in the success of The Fremont Street Experience, the Four Queens Hotel and Casino contracted with Harris Consulting Engineers in Las Vegas to design an additional access opening. This new, 48 foot opening would be located between the existing entrances. The hotel wanted the new entrance to open without doors. This required the design and building of an air curtain to separate the casino from the outside elements. Precise control of the airflow Because of the hotel’s design, the air curtain would be obstructed by existing structural supports Here’s where the hotel encountered a problem. Because of the hotel’s design, the air curtain would be obstructed by existing structural supports. And, in order to maintain proper building pressure, the air curtain had to provide precise control of the airflow around the obstructions and down to the return air grate which is also the walkway into the casino. In addition to maintaining the pressure in the building to prevent the loss of conditioned air from the casino, energy consumption and comfort were significant design criteria. With the assistance of Long & Associates, Inc., Ruskin’s Las Vegas representative, the Harris team responded to the challenge by designing a custom air curtain that provides precision air flow around the existing structural supports. IAQ50 air flow measuring and control dampers Built using Ruskin’s IAQ50 air flow measuring and control dampers, the new air curtain successfully provides consistent airflow. The system includes two 65,000 cfm centrifugal fans installed in the space below the return air walkway grate. The air returns through the grate into the basement plenum and passes through two 144 square foot filter and coil banks. It is then ducted up from the fans into the plenum space above the air curtain supply opening. The air then passes through the IAQ50 air flow measuring/control dampers and is directed through an adjustable deflection type grille. The individual IAQ50 dampers measure and control the airflow between the existing structural supports The individual IAQ50 dampers measure and control the airflow between the existing structural supports. This helps guarantee the air curtain maintains the required velocity and prevents conditioned air from escaping through the opening. “Opening up the Four Queens to the Fremont Street Experience has been a tremendous success,” says Max Proctor, Four Queens Building Manager, adding “We are exceeding our revenue projections with this improved access to our casino.” Custom air curtain design “Ruskin’s IAQ50 air flow measuring and control dampers are the key to the design of this custom air curtain,” says Floyd Harris, Principal of Harris Consulting Engineers, adding “Without the precision control of the air velocity around the structural obstructions, it would result in uneven flow through the supply grille and loss of the air barrier." "That means conditioned air would have escaped into Fremont Street. The support given by Ruskin and Long & Associates throughout the design, installation and commissioning of this system was outstanding.” The IAQ50 air flow measuring control damper is designed to fit the needs of a variety of applications. It is this type of versatility that helped the project succeed. Harris Consulting Engineers demonstrated their commitment to providing engineered solutions for their customers by incorporating this unique product into their custom air curtain design. The Ruskin IAQ50 air flow measuring and control damper is one of many products available through Ruskin’s network of representatives.
