ASHRAE wraps up first hybrid Winter Conference

ATLANTA, Georgia, 4 February 2022: More than 2,800 HVACR industry professionals, building systems engineers, architects, contractors and students gathered in Las Vegas and virtually from January 29 to February 2 for the 2022 ASHRAE Winter Conference, ASHRAE said through a Press release. Registered conference attendees received entry to the co-sponsored AHR Expo, held from January 31 to February 2 at the Las Vegas Convention Center, ASHRAE added.

“This year’s Conference and Expo marked the first time that the Society has been together for our Winter Conference in two years and the return to the AHR Expo after last year’s cancellation,” said Mick Schwedler, 2021-22 ASHRAE President. “While the numbers are expectedly lower than past conferences, in-person attendance still exceeded our expectations, and our virtual attendees added a welcomed dynamic to our sessions. We are grateful to everyone involved in establishing a comprehensive health and safety plan for our attendees, which included guidance provided by the ASHRAE Epidemic Task Force.”

According to ASHRAE, the Winter Conference featured over 50 technical sessions, updates from Society leaders, tours, social events and livestreamed sessions for virtual attendees. Top sessions included Introduction of Building Decarbonization, HVAC Design, Control and Operation of Hospitals After COVID-19 Fiasco and CPS 21: Refining ASHRAE COVID Guidelines and Standard 100, ASHRAE said.

According to ASHRAE, the AHR Expo offered a total of 1,573 exhibitors, with 281 international exhibitors, occupying 443,769 square feet of exhibit space in the Las Vegas Convention Center. More than 43,000 people pre-registered to attend the show, including 130 media representatives, ASHRAE said.

At the Winter Conference, Schwedler provided updates related to the Society’s current theme, “Personal Growth. Global Impact. Feed the Roots”, ASHRAE said. He focused on personal development and how the Society’s extraordinary global growth and impact to the built environment has nourished the roots of the global HVACR industry, ASHRAE added.

“When we concentrate on our mission and vision and talk about our impacts – we make the world more sustainable and resilient to future changes,” Schwedler said. “We reduce both energy utilization intensity and environmental emissions. We helped mitigate a global pandemic by keeping vaccines cold – and their efficacy high – 40% of the world’s food spoils between the field and consumption. We reduce that. And most importantly, we keep students and staff in schools, and occupants of the built environment safe and healthy.”

During the plenary session of the Conference, Jeff Littleton, Executive Vice President and Secretary, ASHRAE, reported on the Society’s current initiatives, as well as the dedication of ASHRAE volunteers during the pandemic. “A Diversity, Equity and Inclusion Board subcommittee is focused on proactively driving diversity, equity and inclusion at all levels of the Society,” Littleton said. “Task groups have been formed to drive Society strategies on decarbonization and on international standards. We’ve released 14 new and 24 revised publications and standards.

Examples of new publications include the ASHRAE Design Guide for Natural Ventilation and the ASHRAE Guide for HVAC in Hazardous Spaces. We’ve even released the children’s book, Lucy’s Engineering Adventure. The commitment of ASHRAE’s entire global membership to the Society’s work has never wavered during the pandemic. I find that truly remarkable. When so much of our professional and personal lives has been disrupted, some 7,000 ASHRAE volunteers at the society, regional and chapter levels continue to drive ASHRAE forward.”

ASHRAE said an honors and awards ceremony, tied to the Conference, was an occasion for recognizing experienced and emerging leaders in the industry. Record-breaking polar explorer, Ann Daniels, closed the plenary session with an inspiring presentation on good leadership, teamwork and self-belief.

The ASHRAE Learning Institute (ALI) offered 17 courses. According to ASHRAE, new courses were as follows: Advanced High-Performance Building Designs: Key Concepts for Lifelong Building Sustainability; V in HVAC – What, Why, Where, How, and How Much (includes Basic Requirements of Standard 62.1-2019); Best Practices for Installing DDC Systems; Save 40% by Complying with Standard 90.1-2019; Principles of Building Commissioning: ASHRAE Guideline 0 and Standard 202; Guideline 36: Best in Class HVAC Control Sequences; Changing Environments and Loads for Data Centers (High Density, Liquid Cooling, Edge Computing); and Health Impacts of Indoor Air Extraction, Ventilation, and Filtration – Same or Different.

ASHRAE said all registered attendees, both in-person and virtual, would have access to the virtual conference environment for 12 months, post-conference. Registration, the Society said, is still open for access to the virtual conference until January 2023 at ashrae.org/2022winter.

ASHRAE said the 2022 ASHRAE Annual Conference will take place from June 25 to June 29 in Toronto, Ontario, Canada. The 2023 Winter Conference will take place from February 4 to 8, and the AHR Expo, from February 6 to 8, in Atlanta, Georgia.  

AABC, ACG and EMA to conduct workshop on commissioning at AHR Expo

LAS VEGAS, Nevada, 30 January 2022: The Associated Air Balance Council (AABC), the AABC Commissioning Group (ACG) and the Energy Management Association (EMA) said they are exhibiting and presenting at AHR Expo 2022, the world’s largest HVACR marketplace. The engagement includes a CxA Workshop on February 1 and 2 at the Expo AHR Expo.

The two-day, 12-hour-long workshop includes discussion of the commissioning process, as described in ACG’s Commissioning Guideline, as well as practical insight on skills, strategies, and communication and documentation protocols essential to applying the process on “real world” projects. This highly interactive training includes many small-group breakout activities, where attendees will use project case studies to develop and discuss samples of key commissioning deliverables, the three entities said. After the workshop and on the final day, a CxA certification exam is administered to approved candidates.

The instructional portion of the CxA Workshop is open for all to attend. The ACG is at Booth C4915 in the Central Hall.

According to ACG, those interested in attending can register at https://www.commissioning.org/register-for-cxa-workshop-exam-at-ahr-expo-2022/ 

ASHRAE To host Tech Hour on building commissioning

ATLANTA, Georgia, 1 April 2021: ASHRAE premiered ‘Tech Hour #3: Commissioning’. It is presented by Jay Enck, Co-Founder and Chief Technical Officer of Commissioning, Green Building Solutions, Inc. and Reinhard Seidl, Principal, Taylor Engineering LLP, ASHRAE said.

The Tech Hour series, ASHRAE said, provides relevant technical content in the form of one-hour videos to members and interested individuals through the ASHRAE 365 app.

The third in the series will analyze the impact of climate change and evolving technology on commissioning of new and existing buildings, ASHRAE said. Viewers will learn about evaluating building characteristics and usage patterns that affect building energy footprint and occupant productivity, in addition to data presentation and communications to facility managers and O&M staff, it added.

According to ASHRAE, viewer learning points include:

  • Understanding why commissioning existing building stock is so important.
  • Important steps to reducing energy consumption.
  • How new technologies help in implementing higher systems efficiency and ongoing Cx with cloud-based documentation methods and energy monitoring.

According to ASHRAE, one PDH will be available to viewers upon completion of a survey link in ASHRAE 365. Due to the cancellation of many in-person ASHRAE Chapter meetings and the DL program, the PDH period for Tech Hours has been extended through June 30, 2021, ASHRAE added.

To view ASHRAE Tech Hour videos, ASHRAE suggested downloading ASHRAE 365 on the App Store or Google Play.

ASHRAE Epidemic Task Force releases updated Building Readiness Guide

ATLANTA, Georgia, 02 February 2021: With the performance of many HVAC systems in buildings still being evaluated, the ASHRAE Epidemic Task Force has updated its reopening guidance for HVAC systems to help mitigate the transmission of SARS-CoV-2, ASHRAE said through a Press release.

“The Building Readiness Guide includes additional information and clarifications to assist designers and commissioning providers in performing pre- or post-occupancy flush calculations to reduce the time and energy to clear spaces of contaminants between occupancy periods,” said Wade Conlan, Lead, ASHRAE Epidemic Task Force Building Readiness team. “New information includes the theory behind the use of equivalent outdoor air supply, method for calculating the performance of filters and air cleaners in series, and filter droplet nuclei efficiency that help evaluate the systems’ ability to flush the building.”

According to ASHRAE, major updates to the building readiness guidance include the following:

  • Pre- or post-flushing strategy methodology: The strategy has been updated to include the use of filter droplet nuclei efficiency, which is the overall efficiency of filter, based on viable virus particle sizes in the air, to assist in determining the impact of the filter on the recirculated air on the equivalent outdoor air. This allows the filter efficiency as a function of particle size, using ASHRAE Standard 52.2 test results, to be estimated based on the expected size distribution of virus-containing particles in the air. This calculation is currently based on Influenza A data and will be updated as peer-reviewed research becomes available for the distribution of particle sizes that contain a viable SARS-CoV-2 virus. Additionally, a chart has been added to help determine the time to achieve 90%, 95% or 99% contaminant reduction, if the equivalent outdoor air changes per hour is known.
  • Flushing time calculator: There is now a link to a view-only Google Sheet that can be downloaded for use, to help determine the available equivalent outdoor air changes and time to perform the flush. This sheet is based on a typical mixed AHU with filters, cooling coil, with potential for in-AHU air cleaner (UVC is noted in the example), and in-room air cleaning devices. Provided efficiencies of MERV-rated filters are based on the performance of over 200 actual filters from MERV 4 through 16, but the tool also allows users to enter custom characteristics for specific filters.
  • The sheet also calculates the filter droplet nuclei efficiency, based on the cited research but allows a user to adjust the anticipated distribution of virus, as desired. It also allows specification of the zone (room) air distribution effectiveness from ASHRAE Standard 62.1 to account for the impact of the HVAC system air delivery method on the degree of mixing. Default calculations assume perfect mixing. Finally, the tool allows for the target air changes to be adjusted if an owner wants to achieve a different per cent removal in lieu of the recommended 95%. 
  • Heating season guidance: The guide now includes data to consider for heating of outdoor air and the potential impact on pre-heat coils in systems.
  • Adjustments to align with Core Recommendations: The Core Recommendations were released in January 2021, and this guidance document needed to be updated to ensure that the information provided aligned with the intent of those recommendations. This included minimum outdoor air supply and filter efficiency requirements and their role in an equivalent outdoor air supply-based risk mitigation strategy.

According to ASHRAE, the guidance still addresses the tactical commissioning and systems analysis needed to develop a Building Readiness Plan, increased filtration, air cleaning strategies, domestic and plumbing water systems, and overall improvements to a system’s ability to mitigate virus transmission.
