    Fiber glass is one of the most studied man-made substances on the planet, and there are dozens of studies specifically designed to determine whether fiber glass poses any health hazard to humans. These third-party studies have produced a robust body of scientific evidence supporting the safety of fiber glass in air handling applications.  However, despite the evidence supporting both its safety and performance, there are still some lingering fears about the safety of fiber glass. Primarily:

    The Health and Safety Partnership Program is a voluntary workplace safety program for workers involved in the manufacture, fabrication, installation, and removal of glass wool and mineral wool products. This article describes one element of this Partnership Program, the development of an occupational exposure database that characterizes exposures by fiber type, industry sector, product type, and job description.

    One of the most important components in any building is the HVAC system. The air handling duct system is one component of the HVAC system. Since fiber glass insulation products are used in the majority of duct systems installed in the United States, the North American Insulation Manufacturers Association (NAIMA) has prepared this booklet to give you a quick overview of how insulation fits into the overall indoor environmental picture.

    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.
