President’s Corner

National Capital Chapter Members,

We have officially reached the last stretch of winter and the beginning of spring. Spring is a time of renewal not only in the environment around us, but also with our chapter. The nominating committee for next years board has been selected and actively working on identifying the key leaders which will continue the success of our chapter for years to come. Stay tuned to the monthly meetings and notifications for more information!

Last month continued the theme for this year of Decarbonization with two great speakers. Our PES featured Rock Ridolfi providing us with a “roadmap to decarbonization.” He focused his discussion on many things, but what stuck out to me was how to address efficiency first and first cost second. In a world of tighter budgets its becoming harder to push the limits of efficiency while maintaining reasonable budgets for owners. For our dinner presenter, one of our chapter sponsors (Boland Trane) assisted by having one of their experts speak on specifically hydronic systems and decarbonization. Scott Delo energized the crowd with a technical overview of a variety of hydronic components and how they help feed into the growing decarbonization trend.

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!

March’s meeting is a special one every year. It’s Past President’s night in our chapter. This is a meeting in which we recognize, in front of all chapter membership, the commitment and value that all the past presidents of our chapter have given not only locally, but to ASHRAE Society. I know the valuable mentorship provided year after year allows our chapter to continue to be successful, and I look forward to personally thanking them all for their past years of service. I really hope you can join us!

Wishing our members continued health and wellness!

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

Wednesday, March 13th, 2024

Theme: Past President's

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

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


Topic: Clearing the Air: A Comprehensive Exploration of What’s New in the World of ASHRAE and the Landscape of Filtration, Indoor Air Quality, and 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.

Josh Howell Bio:

Joshua Howell is a Certified Air Filtration Specialist (CAFS) with Dynamic Air Quality Solutions where he collaborates with owners, architects, engineers and design teams on matters involving IAQ, energy savings, maintenance, sustainability and facilities management solutions. In this role Josh has provided analysis for particulate and contaminant control on a wide variety of projects within key market segment that include healthcare, government, higher education and museums. Josh is a graduate of the U.S Naval Academy and has completed post graduate studies at the Project Management Institute and Syracuse University.

Caitlin Naske Bio:

Caitlin Naske is the Lead Chemical Engineer at Dynamic Air Quality Solutions.  With over 12 years of experience in air quality, activated carbon and adsorption, Caitlin provides expertise in gas phase and particulate contaminants and methods for improving indoor air quality.

Prior to working for Dynamic, Caitlin worked for Ingevity (formally known as MeadWestVaco, MWV), an activated carbon manufacturer, where she worked in product development for air purification and corrosion prevention.  During her tenure she was involved in reformulating activated carbon products and extensive application testing including designing accelerated and long term product validation testing.  Caitlin then brought her expertise to Dynamic applying it to improving indoor air quality through applications design and testing and product development and validation.

Caitlin is the committee Chair of the new ASHRAE standard 145.4P “Method of Test for Assessing the Gas-Phase Performance of Air Cleaning Devices and Systems in a Duct-Chamber Apparatus”.  She is also actively involved in ASHRAE committees including SSPC 145, TC 2.3, and TR4-IAQP.

Presentation Abstract:

This presentation aims to provide a high-level examination of ASHRAE standards and guidelines and the latest revisions, releases, and developments. Key ASHRAE advancements will be spotlighted, providing insights into how these standards and guidelines will contribute to shaping advanced strategies for filtration, indoor air quality and decarbonization.

This presentation will delve into topics including:

The approval and release of ASHRAE Standard 241 “Control of Infectious Aerosols” and the introduction of new concepts such as Equivalent Clean Airflow Rate, a novel approach that considers the cumulative impact of outdoor airflow, indoor air filtration, and air disinfection technologies.

Background and key aspects of ASHRAE Guideline 44P “Protecting Building Occupants from Smoke During Wildfire and Prescribed Burn Events” covering proposed recommendations for building measures related to the design, installation, commissioning, operation, and maintenance of building envelope, ventilation, and air cleaning systems.

Notable changes to ASHRAE Standard 170 “Ventilation of Health Care Facilities” highlighting ventilation system design and updated language to filtration placement and MERV rating requirements.

Notable changes to ASHRAE Standard 62.1-2022 “Ventilation and Acceptable Indoor Air Quality” including the addition of defined design contaminants for use in the mass balance equations for easier application of the Indoor Air Quality Procedure.

The development of new test method standards such as Standard 185.5P “Method of Testing HVAC-duct mounted Devices and Systems and In-Room devices for Particle and Microorganism Removal or Inactivation in a Chamber with a Recirculating Duct System” Standard 145.4P “Method of Test for Assessing the Gas-Phase Performance of Air Cleaning Devices and Systems in a Duct-Chamber Apparatus” and their anticipated use in ASHRAE standards to promote proper use and implementation of air cleaning technologies.

Topic: Sustainability Considerations in a Data Center

When: 5:30 PM – 8 PM EST

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

Mukul Anand Bio:

Mukul Anand has 27 years of HVAC industry experience, 15 years specifically in data center infrastructure design. He is currently the global director of business development at Johnson Controls. Mukul has also served as the global director of Application Engineering and the General Manager of the Modular Datacenter business. Mukul leverages his expertise in datacenter cooling, sustainability, product management, energy management, and applied HVAC to collaborate with customers, provide strategic guidance and launch specialized products for evolving datacenter infrastructure. Mukul has an MS Degree in Thermal & Fluid Sciences and an MBA, both from University of Maryland, College Park.

Presentation Abstract:

Data Centers are mission critical facilities where uptime & risk management are the primary focus. Sustainability, including a detailed analysis of efficiency, design power consumption, embedded carbon, GWP, WUE, Noise & future-proof designs, is also critical. The swift expansion of multi-story data centers and dense rack configurations intensify the heat island phenomenon. When these trends intersect with prominent markets and their associated high ambient temperatures, they present reliability issues for data centers. Having a dynamic chilled water setpoint and a variable cold aisle temperature optimizes energy use and enables right-sizing of HVAC equipment. A detailed review of thermal design considerations and limited excursions outside of recommended / allowable ranges can guide optimal design and sequence of operations for the most sustainable data centers.
