    There are measurable benefits associated with insulated heating, ventilating, and air conditioning (HVAC) ducts: conditioned air delivery becomes more efficient, occupant comfort is improved, energy is conserved, and the ducts operate more cost-effectively with less noise. The best way to assure that the HVAC system will provide these benefits on a continual basis is by employing a regular system maintenance schedule. This, along with a high-efficiency filtration system, assures protection of both HVAC system components and the building occupants. Click here to read more!

    In typical HVAC system construction, engineers and contractors will work together to produce quality systems, but sometimes, the messages between the two can become muddled in translation. This generally comes down to issues with the specifications and how they are interpreted. The results can impact the short-term and long-term cost, efficiency, accuracy, and productivity. To learn more about some of the more common specification pitfalls, we recently sat down for an interview with Steve Dockery, Vice President of Spiral Pipe of Texas.

    Do my ducts leak? Most likely.  ASHRAE says that 75% of all ducts in commercial buildings leak 10-25% That’s 200-700% higher than ASHRAE’s recommended standard of 3%! This short duct leakage assessment consists of 14 questions and is a helpful tool that allows you to estimate fractional duct leakage within a system.

    For years, Americans who would never put up with leaky plumbing pipes have been willing to accept leaky ducts. While water damage is hard to ignore, the damage caused by leaky ducts is more subtle. Yet leaky ducts not only waste huge amounts of energy — they can also lead to comfort complaints, moisture problems, mold, and rot.

    St. Luke’s Cataract & Laser Institute, which says it has performed more cataract surgeries than any other eye care clinic in the world, uses ultraviolet germicidal irradiation light systems for disinfecting its surgery rooms and promoting clean HVAC construction system coils for better indoor air quality.

    Properly specifying insulation for duct systems is not a one-size-fits-all endeavor. In order to effectively optimize system performance, ensure indoor air quality (IAQ), and meet code requirements, there are a number of critical variables specifiers should consider prior to selecting an insulating material. These include things like coatings, facings, installation methods, duct system components, code requirements, and the specific performance needs of the application itself.

    Understanding where we can gain and lose energy in an HVAC system isn’t always a straight-forward endeavor. Energy loss can stem from any number of reasons, like leaking duct systems or neglecting to lower the system demands during hours where the building is unoccupied. Considering this, the number of variables that go into maximizing energy efficiency can be daunting to say the least. That’s why the National Renewable Energy Laboratory has created a comprehensive checklist of the myriad of aspects of a building where we can look to save energy.

    Installing buried ducts in attics, if done properly, has the potential to save dramatically more energy than the typical vented attic setup, but there are definitely some questions about how it’s done and where to use the method properly. Insulation Institute partnered with Home Innovation Research Labs to look into the details of using buried ducts in attics, and how to do so while ensuring that you’re still meeting the 2018 IECC standards. Read, "A New Guide on Vented Attics with Buried Ducts."

    Many businesses are looking for new ways to boost productivity and enhance worker wellbeing, and more and more studies are showing that one of the best ways to do that is by improving indoor air quality (IAQ). Some studies have shown that improving IAQ can actually increase productivity and worker satisfaction by 0.5 – 5% - or if we look at the dollar signs, that equates to $20 to $200 billion in estimated annual savings. But where do we start and what do we need to be looking for?

    Every month, we receive several requests to respond to outdated duct liner specifications, and one question we often see specifically pertains to liner density. In today’s world of improved manufacturing technologies, a material’s physical density is far less relevant to selecting a duct liner product because density has little correlation to thermal and acoustical performance. In fact, density as product selection criteria for duct liner was written out of the specification over 30 years ago!
