AFE 6 - Greater Philadelphia


Chapter 6 slider



Reactivated on May 18, 2010, Chapter 6 has been going strong since! As one of the oldest chapters of AFE (nee AIPE), it was one of the most prestigious and active chapters for years; but it became inactive for a few years in the 1990's. We meet nine months out of the year, skipping July, August and December, and offer educational presentations as well as tours of local industry or places of interest. The technical presentations earn CEU credit for the attendees.


Throughout the years since AFE incorporated (1954) as the American Institute of Plant Engineers, Chapter 6 has been prominent within the organizations by taking a national presence with many of its members holding several national offices

Why Do We Exist?

The Greater Philadelphia Chapter (6) of the Association for Facilities Engineering believes in and supports the mission of the Global organization which is to provide resources, education, leadership and networking opportunities for our members. On the national level, AFE offers certifications, Journal, webinars, our Annual Business Meeting & Leadership Conference, and other resources such as AFE Connections. At the local level, Chapter 6 has nine meetings per year with most being educational/networking meetings with some occasional tours of local facilities of interest scheduled. Obviously with the COVID pandemic, we have been meeting virtually with much success with attendance and educational presentations. Be sure to go to the EVENTS calendar to view all the upcoming events for Chapter 6. Some of our recent events are pictured on the slider at the top of this page.

Greater Philadelphia Chapter 6’s March meeting was a virtual meeting held on the Zoom platform. Seven people logged into the meeting. David Hossfeld and Carol Shenk of SageWater were the featured presenters. Highlights of their presentation included:

  • Discussion about the four main piping systems: supply piping; drain, waste and vent piping; hydronic piping; sprinkler piping.
  • How engineers and/or building managers can estimate the useful life of piping systems. According to Fannie Mae and HUD, domestic piping systems have an estimated useful life of 30 to 50 years, and drain, waste, & vent piping has an estimated useful life of 50 years.
  • Supply piping materials and their age-related issues
  • Preventive maintenance procedures, including exercising valves regularly; setting up schedules for cleaning lines; training building occupants in shut-off procedures in case of an emergency.
  • Documenting leaks and piping issues. Keeping a Leak Log

Greater Philadelphia Chapter 6’s April meeting was a virtual meeting held on the Zoom platform. Ten people logged into the meeting. Jim Clark of Clark Energy, Inc was the featured presenter. Highlights of his presentation included:

  • Building owners have shut down on-site operations due to COVID-19 and many employees are working from home. Strategies to reduce energy usage during this period were presented that could reduce energy usage by more than half.
  • Building staff should carefully record all changes so they can easily be reversed when people move back into the building.
  • Discussion of ASHRAE recommendations for ventilation of buildings
  • Surface contact is now considered to transmit COVID-19 less than originally thought. The research is leaning more towards transmission through aerosols (small airborne droplets), which can travel over twenty feet and linger in the air for hours.
  • Too much outside air can cause increased sickness due to very low and very high humidity levels, which allow viruses and bacteria to grow much faster and mold to form. The optimum range of relative humidity is 40 – 60%.

  • Filters with a rating of MERV 13 or higher are recommended where possible.
  • The CDC has stated that being in the room with a person with COVID-19 for more than 30 minutes per day greatly increases the risk of contracting the disease.
  • Mitigation measures such as UV lighting, bipolar ionization, and other technologies were discussed. Proper application and location are important. Certifications for safe Ozone levels are recommended. Many of these measures have potential side effects that should be considered.
Chapter 6 wishes to thank Jim Clark very much for his loyal support to our chapter over the years. We appreciate the knowledge and expertise that he has in his field of business.
