    Corporate office space is undergoing a rapid transformation. Traditionally, these spaces included a ring of private offices around the perimeter of the space, with cubical farms occupying the center. Today, companies are moving to more of an open office plan, which requires different considerations for HVAC system design.

    Companies looking for insulation replacement solutions for commercial buildings should keep in mind that there are many wrong ways to implement these projects. Mistakes made in getting commercial installation in place can destroy energy efficiency initiatives and cost businesses a lot of money. They can lead to non-compliance with industry standards, and raise risks.

    Here are some of the things that a professional HVAC company takes care to avoid during commercial insulation repair projects for a business client.

    The 2018 edition of the International Energy Conservation Code (IECC) has been published, and it includes new provisions regarding HVAC ducts buried in vented attic insulation. The code changes, proposed by Craig Drumheller from the National Association of Home Builders (NAHB), allow ducts to be buried in attic insulation, and when using the performance path, provides credit for the improved duct efficiency.    

    We sat down with Craig to dive into some of the details of his proposed code change, and how it can influence duct system design and energy savings.

    Johns Manville is proud to announce its release of the first ever flexible fiberglass duct liner with an R-12 thermal resistivity rating. This innovative insulation is designed specifically to meet the new code requirements set forth by the IECC in 2015 that mandate the use of R-12 insulation on ducts in unconditioned spaces in climate zones 5-8.

    Rooftop ducts pose a unique set of variables that can influence insulation material selection. The simple fact that they are outdoors sets a different bar for performance requirements than typical indoor HVAC applications. As a result, installers and specifiers frequently look for specific material features and performance benefits when they select a material for rooftop ducts.

    Several research studies have taken a close and practical look at duct systems in homes. The results are astounding. They show duct leakage and location of supply and return outlets have a much greater impact on overall home energy usage than previously thought.

    The magnitude of the observed leakage from an uninsulated system when the air handling unit is turned on may double or triple the home infiltration rate and increase space conditioning costs by an estimated 10% to 12%.

    This report assesses 182 different heating, ventilation, and air-conditioning (HVAC) technologies for U.S. commercial buildings to identify and provide analysis on 17 priority technology options in various stages of development. The analyses include an estimation of technical energy-savings potential, description of technical maturity, description of non-energy benefits, description of current barriers for market adoption, and description of the technology’s applicability to different building or HVAC equipment types.
