President’s Corner

National Capital Chapter Members,

Happy New Year to all of our membership! I hope that the holiday season was restful and enjoyable to all. As we wrap up with the month of January we have officially crossed the halfway point of the chapter year!

Reflecting upon on last meeting, it was a joy to engage on such diverse topics. For the virtual PES we had Tony Fuchs present on “Hybrid Ventilation Strategy in Early Design to Achieve Cost/Carbon Savings and Enhanced IAQ.” Coming out of the pandemic, enhanced IAQ is certainly at the forefront of most of our memberships minds, and it was great to hear the strategies on how to engage early, but also shown not only owner cost savings, but carbon reductions compared to other systems. We continued our in person dinner presentations with John Boggs presenting on Liquid Cooling in Data Centers. This topic is of particular interest in the chapter coverage area (especially Northern VA) and it was great to hear about the emerging use of liquid cooling systems and the impact it may have on existing and future data centers!

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!

February’s theme is Young Engineers in ASHRAE (YEA) and Membership Promotion. I have challenged our chairs of these committees to strive to continue to maintain our active memberships this up coming spring. The YEA group in particular is looking at a few fun events this spring – so stay tuned!

Membership Promotion is the backbone of ASHRAE involvement. We are a society steered and directed by our membership. Without members, we would not be able to continue to be on the forefront of all technological advances. Our overall membership has been in a slight decline these past few years, so its more important than ever to reach out to someone in your circle, firm, or project and encourage them to reap the benefits you see in ASHRAE membership!

I’m looking forward to some very entertaining and involved events this spring that our committee chairs are diligently working on for our chapter. One major event upcoming in February is the Winter Social to be held at Convene in Arlington. Not only does it give a great opportunity to network and reset on the new calendar year with your chapter members, but it has a great panoramic view of DC!

Wishing our members all the best!

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

Wednesday, February 7th, 2024

Theme: Membership Promotion / Young Engineers in ASHRAE (YEA)

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

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


Topic: New Construction to Existing Buildings: Roadmaps for Decarbonization

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.

Rock Ridolfi Bio:

Rock joined EEI as an Associate following the acquisition of Rivion in early 2023. He brings 14+ years’ experience working in the building performance analysis and commissioning industry. As an Associate, Rock is responsible for the daily operations of EEI's Wisconsin branch and the experienced team of building consultants, energy engineers, and commissioning agents.

Notably, Rock has been involved on projects around the globe, including those pursuing LEED, WELL, Fitwel certification, and PACE financing, totaling 200+ certifications and 60+ million square feet in both New Construction and Existing Buildings.

Beyond project work, Rock remains actively engaged within the industry, serving as the Chair of the USGBC Water Efficiency Technical Advisory Group 2022-2024 and as a committee member for ASHRAE 189.1 Standard for the Design of High-Performance Green Buildings.

Presentation Abstract:

The presentation will focus on key milestones of a building decarbonization roadmap whether beginning fresh in new construction or jumping in on an existing building. We will highlight key and supporting actions that can be taken to decarbonize your client's buildings or portfolios, emphasizing the use of low-carbon materials, electrification of fossil fuel-based end uses, and quite simply the importance of efficient design and construction. Thinking first efficiency, not just first cost. The roadmap will be presented as a useful framework for outlining the suite of policies and changes needed to achieve decarbonization goals and the national and local regulations driving EUI Target achievement and emissions reduction.

Topic: Building Decarbonization for Hydronic Systems

When: 5:30 PM – 8 PM EST

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

Scott Delo, PE, CEM, BEMP Bio:

Scott Delo is a member of the Applications Engineering team based out of Lacrosse, WI, but works remotely from his home in Pittsburgh, PA.  His areas of expertise are in chilled water systems, controls, and existing building applications.

Scott has been with Trane for over 14 years.  He started in the Customer Direct Services (C.D.S.) department in Lacrosse supporting TRACE 700 and worked on the development of TRACE 3D Plus. In 2015 Scott moved back to his hometown of Pittsburgh and joined the Mid-Atlantic region of Trane as a Project Developer and Energy Engineer.  There he developed energy turnkey and performance contracting projects for building owners.  Scott also worked as an Energy Engineer/Account Engineer on the Mid-Atlantic Digital Services Team.  In that role Scott used Trane’s building analytic software to identify building control issues and develop solutions for customers.  He is an Army Veteran having served as an engineering officer in the Wisconsin and Pennsylvania National Guard for a total of 8 years.

In Scott’s free time he enjoys working on fixing up his house, visiting national parks, hunting, and going on long hikes with his wife Audra and dog Lucy.

Presentation Abstract:

Many people are familiar with decarbonization and its goals. Scott will delve into how hydronic systems using heat recovery chillers, heat pumps, and chiller/heaters can be designed, piped, optimized, and controlled in order to provide heat efficiently. He will also cover the impacts of hot water and outdoor air temperatures, methods to simplify system design and operation, as well as the importance of ensuring building operators and facility managers can operate the systems as intended.

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.
