President’s Corner

National Capital Chapter Members,

We have officially kicked off the chapter year and I want to again thank our presenters for a very successful and well attended September event. Our first Virtual PES on the “Use of Natural Refrigerants in our Industry” from Kurt Liebendorfer was very educational, especially for those of us who have not had the opportunity to incorporate natural refrigerants into our everyday design practices yet. Coupled with the dinner presentation on the “Refrigerant Transition” from Alex Albrecht, our attendees can now say they are up to speed on the future of refrigerants and alternative technologies in our industry as well.

As a reminder, a major benefit to being a member of the National Capital Chapter this year is that we offer the virtual PES for FREE, meaning no-cost continuing education credits for our licensed professionals!

October’s theme is Membership Promotion and Young Engineers in ASHRAE (YEA). Without an active membership, ASHRAE would not exist or function. We truly are a Society governed by its membership, providing input for the future direction of our industry through updates to standards, work of our technical committees, and development of new guidelines. For those of you with questions about the benefits of being a member in ASHRAE, I encourage you to reach out to our Membership Promotion Chair, Stephanie Gonzalez, at membership@nccashrae.org for assistance.

We cannot have good Membership without having a strong YEA base. Our Chapter and organization grow with continued involvement from engineers, particularly in the under 35 years old. YEA is one of the easiest ways to get involved in our Chapter with fun social events, as well as technical tours or presentations geared toward up-and-coming engineers in our industry. I will reiterate my thoughts from September, that the more active we can be in the committees like YEA, the better our Chapter’s future will be in terms of new ideas, new volunteers, and leadership. If you have any specific YEA questions, I encourage you to reach out to our YEA Chair, Ryan Cleary, at yea@nccashrae.org for more information.

We have an exciting meeting planned this month with topics surrounding decarbonization, as we align our October program theme with the ASHRAE Decarbonization Conference scheduled to take place in Washington DC later this month. I personally would like to invite you to attend and learn more about this topic, as well as how our chapter’s Membership and YEA committees plan to engage with the chapter this year.

Wishing our members all the best!

Please join us for the second meeting of National Capital Chapter ASHRAE's 2023/2024 season:

Wednesday, October 18th, 2023

Theme: Research Promotion / Government Affairs

PES from 12:00 PM - 1:00 PM EST (Virtual)

Dinner from 5:30 PM - 8:00 PM EST (In Person)


Topic: CO2 Emission Reduction in the Building Industry

When: 12 PM – 1 PM EST

Where: Link will be provided when registered for this event. PDHs will be provided to all attendees as in past.

Rachel Coyle Bio:

Rachel Coyle, EIT began her full-time career with Southland Industries as a Mechanical Design Engineer in July 2020. Before starting her career, she received her Bachelor's and Master's Degrees in Architectural Engineering from The Pennsylvania State University. During the first years of her career at Southland Industries, Ms. Coyle has worked on projects in the government, mission-critical, and commercial market sectors. In addition to her design projects, Ms. Coyle studied materials and resources pertaining to CO2 emission reduction in the building industry to prepare for client requests and industry changes relating to this subject. Additionally, she has formed the Carbon Emission Reduction Team within Southland Industries that brings together representatives from across all divisions to analyze and stay ahead of market trends.

An abstract will be provided as part of the registration email.




Topic: Decarbonizing the Built Environment - Reducing Embodied and Operational Carbon from Net Zero Design

When: 5:30 PM – 8 PM EST

Where: Rhodeside Grille (1836 Wilson Blvd, Arlington, VA)

Sean Casey Bio:

Sean Casey CEM, LEED AP is AECOM’s Decarbonization Technical Lead. His experience includes sustainable energy master planning, high performance building design, building energy simulation, and federal sustainability programs. He lives in Vienna, Virginia with his wife and three sons, is a graduate of the University of Colorado Boulder (Go Buffs!), and a proud AmeriCorps alum.

Sean Casey Presentation Abstract:

To prevent global temperatures from exceeding 1.5°C, global net anthropogenic CO2 emissions must decline by about 45% from 2010 levels by 2030 and reach net zero by 2050. The building industry generates about 40% of annual CO2 emissions, so a rapid shift to high-performance building design is necessary to reach the goal. Sean will discuss how the following topics relate to ANSI/ASHRAE Standard 228, Standard Method of Evaluating Zero Net Energy and Zero Net Carbon Building Performance and what challenges and opportunities exist for future work:

  • Reduction pathways for reducing both embodied and operational carbon of the built environment.
  • High-performance building modeling and whole building life cycle assessment (LCA)
  • ANSI/ASHRAE Standard 228
  • Key concepts: embodied carbon, operational carbon, high-performance building modeling, building lifecycle assessment, ANSI/ASHRAE Standard 228

Your comments after each presentation help us to improve educational offerings in the future.


ASHRAE on a national level will be sponsoring a YEA Happy Hour and Tour during the Decarbonization Conference here in DC.

Wednesday, October 25th, 2023


Time: 5:00 PM EST

Location: Lubber Run Community Center 

Description: Featuring net-zero energy design and a landscape-focused approach to the surrounding park, Lubber Run Community Center offers a holistic response to an urban challenge - ultimately creating puble space that is greater and greener for residents.

Happy Hour:

Time: 6:00 PM - 8:00 PM EST

Location: Courthaus Social (2300 Clarendon Blvd, Arlington, VA 22201)

The Research Promotion Committee manages and supports both the Society‐level fundraising and Chapter‐level fundraising of the RP Campaign. Traditionally supporting just research, the RP Campaign was expanded 10 years ago to include support of Education & ALI, Endowed Research through ASHRAE Foundation, YEA programs, ASHRAE Scholarships, and the General/ Unrestricted fund. Research, the backbone of ASHRAE, remains the primary fund of the program with over $2 million raised for this program annually.
