Intro to Commercial Building HVAC Systems and Energy Code Requirements

Overview of common commercial building heating, ventilating, and air conditioning (HVAC) systems as they relate to energy code requirements. Learn about the most common HVAC systems and equipment, along with energy-related components and controls. Several important energy code requirements will be reviewed, including what to look for in the field or on plans. Learning Objectives: Identify common HVAC system types Identify important HVAC controls, including economizers Name high impact energy code items related to HVAC equipment and controls List the steps in verifying fan power calculations Click here to watch this presentation. https://news.jm.com/blog/hvac-insulation/intro-commercial-building-hvac-systems-and-energy-code-requirements

Johns Manville Releases the First Flexible R-12 Fiberglass Duct Liner

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.

Long-Term Corrosion Testing: What Happened Next?

In 2017 and 2018, Johns Manville built upon the long-term, third-party corrosion testing we started in 2016, and the new results are in. The research sought to explore how corrosion under insulation (CUI) impacts a completely insulated pipe system (pipe, insulation, and jacketing) under conditions designed to accelerate corrosion. The test program started in 2016 with two hydrophobic high-temperature blanket insulations (InsulThin™ HT microporous blanket and a silica aerogel blanket) and in 2017 was expanded to include testing on calcium silicate and expanded perlite insulation. While traditional research and testing isolate variables to strictly explore the interaction of insulation on…

Corrosion Testing: Methods, Results & Interpretation

It is often necessary to predict the performance of a specific material in a particular environment to determine the inherent corrosivity of the system. Such tests are often substantially different from those used for corrosion inhibitor qualification, particularly in the case of the corrosion testing of corrosion resistant alloys. Predicting corrosivity is especially important when designing subsea equipment, most of which is extremely challenging to repair or replace once it is installed. Corrosion testing is a widely used method of evaluating a material’s ability to withstand specific environmental conditions. Corrosion in field conditions can be extremely slow, thus accelerated test…
