Efficiency codes, standards drive green ductwork trend _ 2016-09-19 _ achrnews

While the term lacks a conclusive definition, it’s certainly emerged as an industry buzzword. Electricity prices over time Depending on who you’re talking with, the phrase can mean different things, though most agree it typically encompasses recycled materials, various IAQ elements, duct-sealing products, and more. Electricity outage san antonio GREEN MATERIALS

“First of all, ductwork can be made out of recycled content,” Kaufmann said. Electricity and circuits class 6 ppt “DuctSox has fabric ductwork available that is 55 percent recycled polyester, which is a desirable option when seeking LEED [Leadership in Energy and Environmental Design] points.

“Fabric ductwork is lightweight. Electricity lessons 4th grade It’s typically about 90 percent lighter than metal ductwork of the same size and diameter,” continued Kaufmann. Oil n gas prices “The larger the facility, the more structure is needed to support the ductwork. Gastroenterologia o que trata By using fabric ductwork, there is less need for roof support and tether supports to hang it, so you’re really using fewer materials and resources overall. Gas 4 less redding ca There is less solid waste.”

A study conducted at Iowa State University confirmed that linear dispersion, which is used in DuctSox, can bring an area up to temperature very quickly. Gas pain left side Additionally, fabric duct is easy to install, which saves contractors in labor and shortens downtime for end users. Gaston y daniela These are big factors in mission-critical applications, such as data centers.

When it comes to a contractor trying to sell a concept to an owner, time is money, Kaufmann noted. P gasol “Data center managers are concerned with energy usage, and DataSox effectively increases energy efficiency.”

DataSox distributes large amounts of air down data center cold aisles, but with low 400-feet-per-minute (FPM) velocities that do not upset critical equipment intake and exhaust or room return air-containment balances. Gas 99 cents a litre It also offers the flexibility of directional spot-cooling capabilities with adjustable nozzles for high-wattage servers. Astrid y gaston lima reservations The nozzles, combined with specialized porosity and interior air adjustment, allow for on-site testing and air balancing for optimum performance. Gas x dosage chewable DataSox features factory-engineered, energy-efficient ¼- to ½-inch water gauge of static pressure and a 3°-5°F lower temperature delivery due to low entrainment from the surrounding aisles. Bp gas prices akron ohio When utilized with variable frequency drive (VFD) equipment, DataSox features low computer room air conditioning (CRAC) flow rates and helps data centers achieve lower power usage effectiveness (PUE) levels.

Another important LEED aspect is acoustical performance. Austin electricity outage DuctSox can deliver air quietly, and the material is fabric, so it does not reflect sound in a space like traditional metal does. Electricity merit badge pamphlet The SkeleCore frame stops any inflation noise and now has a DuctSox fabric sound attenuator available. Gaz 67 for sale CLEAN AIR

When it comes to explaining green ductwork, Tim Ledden, technical manager, insulation, Armacell LLC, defines it as simply supplying the cleanest air to the building occupant.

“It’s generally people trying to remove contaminants from the airstream and live healthier,” Ledden said. Gas delivery “Many of the chemicals in some of these insulation products and in the ducts themselves are making people sick. Electricity khan academy Some can be linked to illnesses, and, with others, we don’t really know if there is a link yet. A level physics electricity notes People are definitely concerned. Electricity vocabulary There is a growing consumer awareness of all the VOCs [volatile organic compounds] involved in different products.

“Insulation plays a large role because many ducts are lined with it — especially for noise reduction,” he continued. Gas engine tom “So, insulation is in direct contact with the airstream that is going into buildings. Gas giants If there are any contaminants, off-gassing, or VOCs within the insulation itself, they’re directly put into the building because there’s no filter between these items and the air coming into the actual building.”

Armacell’s AP Armaflex duct liner is fiber-free and Greenguard Gold-certified, Ledden noted. Gas national average 2013 “It limits VOCs far below any existing IAQ requirements. Nyc electricity consumption It also protects against condensation and reduces the possibility of mold or any other bacteria or microbial growth on the insulation. Gas engineer salary It’s also easy to clean, which eliminates dust and other contaminants.” REDUCING LEAKAGE

“When people talk about green ductwork, they’re really talking about making it tighter and more efficient, so it has less leakage,” said Steve Ulm, director of marketing, Semco LLC. Electricity billy elliot “If you have less leakage, you’re using less power, which means you’re creating a greener environment because you’re putting out fewer emissions. Gas number density That’s where the green aspect comes from.”

“They’re looking to become as efficient as possible to reduce costs and, ultimately, reduce energy consumption,” he said. E payment electricity bill bangalore “When you look at duct, traditionally, there have been two kinds, round or spiral round, which is what we do, and rectangular. Electricity worksheets high school And, in the past, rectangular duct could potentially leak anywhere from 30-40 percent. Wd gaster theory Newer rectangular duct construction has gotten much better, but there is often still leakage. Gas 93 You still have to take the time to seal it to make it more efficient. Gas variables pogil key Meanwhile spiral round, in and of itself, meets specification because it goes in as one individual piece with less than 1 percent leakage. Gasco abu dhabi Because it’s a mechanical closure, you don’t have to use sealants. Arkansas gas prices But, when you look at the whole system, if you didn’t seal the connections, you could be at 10-20 percent leakage or inefficiency of the system — even with round duct. Gas 10 ethanol In order to meet energy codes and standards, people are either using gasketed fittings or contractors go back and literally have to seal it with a commercial-grade sealant.

“When it comes to HVAC contractors, they’re looking for the quickest, most cost-effective way to assemble ductwork in the system and seal it to reduce their total costs,” he continued. 1 unit electricity cost in kerala “We offer a product called Velocity™ gasketed duct, which is a self-sealing, gasketed joint system. Electricity transmission When you put it together, it creates an airtight seal that meets leakage standards and codes so there is no need to use a secondary product to seal the connection. Electricity grid code It’s probably the most effective method of doing so.”

Bryan Barnes, senior director, business development, Aeroseal LLC, agrees that green ductwork means sealing ducts to increase energy efficiency.

“Leaky ducts don’t just come from connections, they are often created when subsequent work is done to the home through seasonal changes, structural shifting, and a variety of other influences,” he said. Electricity magnetism and electromagnetism “The good news is everybody is talking about the importance of sealing ductwork.

“Sealing ductwork has two major benefits: It saves efficiency from an energy standpoint, and it ensures the equipment you’re putting in the house operates at its intended specifications,” continued Barnes. Gas works park address “So, if you install a 20-SEER air conditioner but you don’t seal the ductwork, you’re going to have about a 25 percent degrade in the potential of that system. Electricity vancouver wa That’s why I would consider it green. Extra strength gas x while pregnant Sealing ductwork means you’re using less energy and minimizing emissions, which is better from an environmental and comfort standpoint in the home.”

According to Barnes, consumers are becoming more educated and aware of the potential for energy savings in addition to comfort and IAQ in homes. 9game “Ten years ago, people didn’t realize there was a comfort solution without tearing out walls and starting all over again. J gastrointest oncol impact factor Duct sealing is a pretty simple solution to make you more comfortable and improve the health and safety of your home without having to destroy it. Electricity and magnetism lecture notes Additionally, duct sealing opens up potential market opportunities for contractors. Electricity labs high school Traditionally, HVAC contractors have been interested in box exchange and replacement. Electricity in indian villages In most areas, about 8 percent of homes offer replacement sales. Gasco abu dhabi location If you have 100,000 homes in a market, 8,000 of them will need replacement equipment during that year. Gas quality The biggest benefit to duct sealing is every one of those homes are potential targets for HVAC contractors. Gas tax oregon It opens up the ability to increase lead generation, sales, and profits. Frictional electricity examples It also sets them apart from the competition. Electricity will not generally cause As consumers become more educated and energy codes stricter, I believe contractors will have to look at these other avenues, like duct sealing, in order to be successful.”

Barnes noted that Aeroseal technology exceeds all existing code enforcements and is prepared to exceed all projected codes, as well. Gas efficient cars under 5000 “We guarantee our product, measure it, and verify it through pre- and post-testing. Electricity storage handbook From a consumer standpoint, it truly is a profit-generating technology that will continue to become more important as we move forward with all of the energy and code enforcement. Electricity deregulation choices and challenges By sealing 95 percent of duct leaks, Aeroseal turns existing ductwork into high-efficiency green ducts.”

According to Mark Smith, business development manager, GreenSeam Industries, a DMI company, reducing duct leakage, improving energy efficiency, and reducing material and waste are the primary components of sustainable duct systems or green ductwork.

“We saw the trend take off in the early 2000s, when energy costs started to rise significantly,” Smith said. Electricity use estimator “Payback on energy-improvement technologies or construction techniques started to make a lot more sense. Arkansas gas and oil commission That’s when we saw the shift to engineers, architects, and the HVAC industry really focus on sustainable construction and energy savings. Electricity projects for grade 6 As energy codes have increased, they’ve pushed companies to work more and more toward energy management and reducing duct system leakage.”

Additionally, energy-efficient duct systems and sustainable construction have become more mainstream in the industry, Smith noted. V lab electricity “There’s been a market shift at this point. Us electricity hertz People have become accustomed to asking for these types of products and construction techniques. Gas in chest They’re just starting to become a requirement instead of something used only on LEED projects.”

“Green ductwork mostly has to do with the efficiency of a system,” he said. Electricity word search printable “It doesn’t only have to do with recycled materials — it also has to do with being more efficient energy-wise. Electricity merit badge worksheet answers It’s green because you’re saving energy.

In addition to that, another point in the ductwork system that’s been a problem and carefully looked at now is the natural leakage of a duct system,” continued Hinden. Electricity billy elliot chords “We offer a number of different insulation adhesives that adhere the fiberglass liner to the sheet metal. Electricity towers in japan But that, in itself, is not sufficient and doesn’t meet SMACNA [Sheet Metal and Air Conditioning Contractors’ National Association] regulations. Gas in back and stomach So, we also sell welded insulation fasteners as well as our Insulflex insulated flexible duct connector.”

“Ultimately, these products are going to be used more and more now because of the industry and how the standards are changing,” said Ulm. Electricity prices per kwh 2013 “It usually starts in the commercial market and then works its way down to the residential level, and it’s working its way down very quickly.”
