President’s Corner

National Capital Chapter Members,

I am honored and excited that our membership has elected me to help guide our chapter over the next year. I know the past few years have been challenging to transition back to in person events, but I have faith that engagement will continue to climb back to a peak of prior years.

We have certainly seen a change coming out of the events of the past few years, and a shift in our membership’s order of priorities – people are more engaged than ever with various industrial societies and social groups and our strong youthful leadership of past years has developed to the point of having more responsibilities at work and in their personal lives. I, myself, fall into this category, and because of that I’m happy to announce a significant change to our approach this year for monthly chapter meetings. We have taken lessons from the COVID years, and all PES sessions this year will be scheduled during lunch hours and run virtually to encourage member participation. Happy hours and Dinner sessions will still be held in person the evening following the PES, but at a new venue – Rhodeside Grill in Arlington, VA. As another added benefit we will be issuing CEU/PDH’s for attendees at BOTH PES and Dinner presentations.

I would like to remind everyone of the importance that we, as membership in one of the most well known and influential HVAC societies, hold in the future of our industry. The technical guidance ASHRAE provides in form of Standards and guidelines is referenced every day in our careers and continues to be the “standard of care” in the industry. Diversity, equity and how to continue to support, grow and develop leaders in HVAC has become a focus of our membership and society. Most recently, ASHRAE is taking on climate change with our Society President Ginger Scroggins’ theme and bringing Decarbonization to the forefront with a National Conference being held in our backyard of Washington, D.C. this October.

Without members like you, ASHRAE Society cannot evolve with our industry’s rapid developments. We are very lucky to have such a large membership base locally, and within that base, a large amount of diverse and youthful members. My focus as your President this year will be to engage with these members and help show the benefits of involvement in our Chapter – whether it be attending a social event with YEA or a panel discussion with WiA. I really believe our Chapter will thrive with engaged members and dynamic programming, as it has in years past.

I hope you are as encouraged and excited as I am to get this year kicked off!

Over the last few years, he has devoted his time serving on several committees with the Global Cold Chain Alliance, Controlled Environmental Building Association, and the International Institute of Ammonia Refrigeration. Kurt is currently serving on the Board of Directors of both CEBA and IIAR.

Kurt Liebendorfer Presentation Abstract:

The pending release of EPA’s new regulation mandating the phasedown of HFC refrigerants, which is scheduled to be issued October 1st, is a major factor supporting the expanded use of “Natural Refrigerants” in several refrigeration markets. The use of Ammonia, CO2 and Hydrocarbons is showing up in supermarkets, refrigerators, industrial air-conditioning systems, and are also greatly expanding in many industrial refrigeration applications such as cold storage, food processing, dairies, wineries and ice rinks. The presentation will highlight these natural refrigeration trends and the new technologies that are making it happen.




Topic: Refrigerant Transition

When: 5:30 PM – 8 PM EST

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

Alex Albrecht Bio:

Alex Albrecht has been with Daikin Applied for 6 years, supporting chiller sales markets, including export and domestic Applications, and Product Management. He holds a Bachelor in Mechanical Engineering from Virginia Tech, and an MBA from the College of William and Mary. Since joining Daikin Applied, he has travelled extensively throughout the US and Canada, presenting on the dynamic and complex changing policies and trends related to refrigerants.

Alex Albrecht Presentation Abstract:

The discussion of this presentation will focus on the historical & current policies related to refrigerants in the HVAC industry, followed by an overview of some of the most popular alternatives being proposed to replace currently used refrigerants.


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


Young Engineers in ASHRAE (YEA) took a tour of Amazon HQ2 Met Park in Arlington! We had a wonderful turnout and excellent engagement. Thank you to all the attendees who came out and made it a success. Special thanks to Brad McNiff and Megan Lubina from GHT Limited for their insight about the cutting-edge mechanical systems in the building.

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.
