ASHRAE Resources Provide Proactive Guidance in Addressing the Spread of COVID-19 in Buildings
Atlanta — ASHRAE, a global society advancing human well-being through sustainable technology for the built environment, has developed proactive guidance to help address coronavirus disease 2019 (COVID-19) concerns with respect to the operation and maintenance of heating, ventilating and air-conditioning systems.
The ASHRAE COVID-19 Preparedness Resources webpage, ashrae.org/COVID19, provides easily accessible resources from ASHRAE to building industry professionals.
“The recent escalation in the spread of coronavirus disease 2019 is alarming on a global scale,” said 2019-20 ASHRAE President Darryl K. Boyce, P.Eng. “While ASHRAE supports expanded research to fully understand how coronavirus is transmitted, we know that healthy buildings are a part of the solution. ASHRAE’s COVID-19 Preparedness Resources are available as guidance to building owners, operators and engineers on how to best protect occupants from exposure to the virus, in particular in relation to airborne particles that might be circulated by HVAC systems.”
Available on the webpage is ASHRAE’s recently approved position document on Airborne Infectious Diseases. The Society’s position is that facilities of all types should follow, as a minimum, the latest practical standards and guidelines.
The following publications are referenced in the position document and on the resources webpage:
- ANSI/ASHRAE Standard 62.1-2019, Ventilation for Acceptable Indoor Air Quality – Outlines minimum ventilation rates and other measures intended to provide IAQ that is acceptable to human occupants and that minimize adverse health effects.
- ANSI/ASHRAE Standard 62.2-2019, Ventilation for Acceptable Indoor Air Quality in Residential Buildings – Defines the roles of and minimum requirements for mechanical and natural ventilation systems and the building envelope intended to provide acceptable indoor air quality in low-rise residential buildings.
- ANSI/ASHRAE/ASHE Standard 170-2017, Ventilation of Health Care Facilities – Ventilation guidance, regulation, and mandates to designers of health care facilities. It addresses hospital spaces, outpatient spaces, and nursing home spaces.
- ANSI/ASHRAE Standard 52.2-2017, Method of Testing General Ventilation Air-Cleaning Devices for Removal Efficiency by Particle Size – Establishes a method of laboratory testing to measure the performance of general ventilation air-cleaning devices in removing particles of specific diameters.
- ANSI/ASHRAE Standard 55-2017, Thermal Environmental Conditions for Human Occupancy – Specifies conditions for acceptable thermal environments and is intended for use in design, operation, and commissioning of buildings and other occupied spaces.
- ANSI/ASHRAE Standard 185.2-2014, Method of Testing Ultraviolet Lamps for Use in HVAC&R Units or Air Ducts to Inactivate Microorganisms on Irradiated Surfaces– Establishes a test method for measuring the intensity of ultraviolet lamps on irradiated surfaces under typical HVAC&R operating conditions.
- ANSI/ASHRAE Standard 161-2018, Air Quality within Commercial Aircraft – Defines the requirements for air quality in air-carrier aircraft and specifies methods for measurement and testing in order to establish compliance with the standard.
- ASHRAE Guideline 28-2016, Air Quality within Commercial Aircraft – Serves as a companion to ANSI/ASHRAE Standard 161, Air Quality within Commercial Aircraft. Includes additional research and supporting information for guidance in assessing and assuring good air quality within the aircraft cabin.
The position document also advises that new and existing healthcare intake and waiting areas, crowded shelters, and similar facilities should go beyond the minimum requirements of these documents, using techniques covered in ASHRAE’s Indoor Air Quality Guide to be even better prepared to control airborne infectious disease (including a future pandemic caused by a new infectious agent).
Because small particles remain airborne for some period of time, the design and operation of HVAC systems that move air can affect disease transmission in several ways, such as by the following:
- Supplying clean air to susceptible occupants
- Containing contaminated air and/or exhausting it to the outdoors
- Diluting the air in a space with cleaner air from outdoors and/or by filtering the air
- Cleaning the air within the room
ASHRAE recommends the following strategies of interest to address disease transmission: dilution ventilation, laminar and other in-room flow regimes, differential room pressurization, personalized ventilation, source capture ventilation, filtration (central or unitary), and UVGI (upper room, in-room, and in the airstream).
Owners, operators, and engineers are encouraged to collaborate with infection prevention specialists knowledgeable about transmission of infection in the community and the workplace and about strategies for prevention and risk mitigation.

Industry advancement was on display from exhibitor booths to new Show features including the first-ever Podcast Pavilion and trend discussions led by AHR Expo Expert Council members.
Westport, Conn. — Professionals from across HVACR descended upon the Orange County Convention Center in Orlando, Florida, February 3-5 for the 2020 AHR Expo. Attendees and exhibitors engaged in three full days of innovation and learning and took an exciting look into the future of HVACR. Spread across 506,090 sq. ft., exhibitors on the Show floor delivered new and never-before- seen products and tech, live demonstrations, networking opportunities and a revitalized energy for the future of the industry. In every education session, council talk, podcast broadcast, exhibitor event and long walk across the Show floor, one thing was abundantly clear —the HVACR revolution has arrived in full force.
“The energy on the Show floor this year was hard to miss. From corner to corner, in every booth, education session, event program, everywhere, it’s clear that this industry is alive and thriving,” said Mark Stevens, Show Manager. “Leading in to this Show we knew there were some big changes happening across the industry and we saw that reflected in Orlando. It is truly an exciting time to be a part of the HVACR community and, if 2020 is any indication, it is just getting started.”
The 2020 Show welcomed over 50,000 attendees, 1,900+ exhibiting companies —577 of which were international as well as 295 who were first time exhibitors.
Victor Grasso (@apprenticegrasso19 on Instagram), an HVAC Service Technician from New Jersey says of his first AHR Expo, “The videos of this Show online don’t do it justice. When you’re here you get to pick up the tool and feel how it actually works. It really assures me that if I purchase the tool in the future, I’ll know that I’m getting the right tool for the job. For a young person like me who is new to the trade, the Show introduced me to a whole other aspect of the industry. I found so many products and companies I would have never known existed. This definitely won’t be my last Show— I’ll be here for Chicago, Vegas, I’ll be here for life.”
“We have received incredible traffic at the Show this year. We’re excited to be here!” said Joe Oberle, Vice President of Corporate Development for Delta Electronics. “Our booth this year included fully integrated and automated products from our subsidiaries Delta Controls, LOYTEC, VIVOTEK and
Amerlux, as well as Delta Electronics’ Industrial Automation and Fan business groups, under the theme ‘Smarter Buildings, Smarter Cities.’”
The 2020 Education Program
The 2020 Show featured more than 200 sessions in the Education Program. This year featured new sessions inspired by trends happening currently across HVACR, as well as those forecasted for the near future. Below is a summary of some of the topics discussed throughout the Show:
Private Equity 101: What HVACR Founders Need to Know
This session provided insight into private equity at a basic level understanding. Private equity is currently investing millions into small-to-medium sized founder-led HVAC companies. A panel of investors discussed the varying types of investor opportunities, how a company is valued and how the partnership process typically works. Attendees were left with an understanding of the options available through partnership in order to make decisions that best fit their business.
Skilled Labor! Overcome the Shortage to Protect Your Business
This session discussed the current state of the industry and the skilled labor shortage. Eighty-two percent (82%) of CEOs report that the skilled labor shortage is a significant business issue. Melissa Boutwell, President at Automation Strategy and Performance, presented attendees with a discussion of why this is happening, how we can prepare as an industry and what some organizations are currently doing to secure current and future market positions.
Building for a Climate Emergency
Ken Sinclair of AutomationBuildings.com led a discussion titled Building for a Climate Emergency. In it, he discussed the declaration of a “Climate Emergency” by over 400 global cities and how it relates to an enormous opportunity for the automation industry as local governments gear up to tackle this challenge. With recent legislation from municipal governments targeting residential and commercial buildings, both new and existing, with aggressive greenhouse gas (GHG) emissions targets, the widespread deployment of state-of-the-art controls systems will be essential to achieving these targets.
“This is my first time attending the show and I’ve found the educational sessions to be extremely beneficial for my professional growth,” said Aaron Byers, Product Engineer. “As a young engineer just starting out in the industry, it’s an outstanding place for me to build my professional network, gain input on what’s going on in the industry, and learn from specialists in my field. I’ll definitely be attending Chicago in 2021!”
2020 was the first year the Show hosted education sessions led by members of the AHR Expo Expert Council. The Council is a collaboration of HVACR experts and thought leaders launched by the AHR Expo in 2019 to educate and stimulate discussion concerning the biggest issues impacting the industry. Their
sessions covered a wide range of industry topics addressing what’s next for HVACR professionals in the coming year. Highlights included:
Obstacles and Opportunities for HVACR in the Next Decade
Panel speakers in this session took an in-depth look at what obstacles and opportunities lie ahead for the next decade of HVACR. Speakers shared different perspectives on speeding up time to value creation, increased focus on well-being and productivity, and the skill-shortage gap in the industry. Panel moderator Nicolas Waern, the Nordic “Building Whisperer,” also provided insight on HVACR in Europe, specifically the Nordics and Sweden.
2020 – Pivoting Towards a Post Carbon World and Impacts to the HVAC Industry
This session covered the pivotal effects mitigating climate change has made to the industry and how the 2020 roadmap will look going forward. As more progressive cities and outspoken younger generations across the world continue to focus on climate change, HVACR is adapting for a 2050 carbon neutral world that’s 1.5 degrees Celsius warmer than pre-industrial times, and outlined how 2020 marks a significant year in this adaptation. This session was led by Luke Leung, PE, LEED Fellow and Director of Sustainable Engineering at Skidmore, Owings and Merrill LLP.
Update on Refrigerants: Past, Present and Future
This session, led by Eckhard Groll, William E. and Florence E. Perry Head of Mechanical Engineering and Reilly Professor of Mechanical Engineering at Purdue College of Engineering, provided a detailed review of current and past refrigeration technology and how it can inform refrigerant technologies of the future. Due to the phase-out of ozone-depleting CFC and HCFC refrigerants, refrigeration and air conditioning sciences have been in a state of flux, and environmental concerns have sparked industry- wide interest in using substances that are naturally occurring in the biosphere as refrigerants. Many of these natural working fluids were commonly used in refrigeration technology in the late 1800’s, and this session emphasized that when looking at the refrigerants of the future, it is essential to understand which substances have been used in the past.
Applying Emotional Intelligence (EQ) to Strengthen Your Business Model and Customer Relationships
Karine Leblanc led a discussion of emotional intelligence and how it has emerged as a key aspect of business management and employee relations. This session explained the importance of EQ, covering key concepts such as connecting with others by discovering common ground, using simple communication, capturing interests, inspiring others and staying authentic in relationships. Attendees left this session with an understanding of how EQ can affect relationships across company, distribution and sales channels.
“It’s all about connection and being in the room. If you don’t show up, you will not meet people, you will not learn and you cannot exchange expertise with people that are working in either the same or different role as you,” said Karine Leblanc, Sales Engineer with US Air Conditioning Distributors and founding member of the AHR Expo Expert Council.
The 2020 Product of the Year honor went to Danfoss for the Danfoss CO2 Adaptive Liquid Management Solution. Danfoss was also recognized as an Innovation Awards winner for the Cooling, Green Building and Refrigeration categories. Winners were selected in a total of 10 industry categories along with an overall Product of the Year winner and honored in a ceremony hosted during the AHR Expo.
“It was an honor to win Product of the Year for our Danfoss CO2 Adaptive Liquid Management (CALM) at the AHR Expo in Orlando considering all of the other category winners,” said Peter Dee, Sales Director Food Retail, North America at Danfoss. “It exemplifies the Danfoss culture, people, and commitment to innovation. We continue to strive through innovation to help our customers and the industry meet their sustainability requirements and it is an honor to be recognized by the industry for these achievements.”
The Innovation Awards received the most entries ever this year since the program began 17 years ago. What’s more, the innovation featured by the winners, finalists and entrants is a true indication that the industry is in a season of change.
“The Innovation Awards is always an exciting time for us at the Show because we get to pause and give recognition to those in the industry who are challenging themselves to make HVACR better,” said Stevens. “This year really delivered, not only in the awards ceremony but also out on the Show floor. We congratulate all our winners —and Danfoss for developing a phenomenal Product of the Year with the CO2 Adaptive Liquid Management Solution— and challenge everyone in the industry to keep innovating, taking risks and working to better the industry.”
“Additionally, the Innovation Awards gives us the opportunity to leave a mark on the communities we visit through the donation of entry fees,” continued Stevens. “This year we were fortunate to give back the largest donation ever —$26,300 — to the Orange County Police Athletic League (P.A.L.) serving the Orlando/Apopka area. We are delighted to be able to support the strong youth program they have developed.”

Updated International Plumbing Code and International Mechanical Code enhance safety, and save time and resources
Washington, D.C. – The International Code Council announced the release of its 2021 International Plumbing Code (IPC) and International Mechanical Code (IMC). Building codes play a significant role in maintaining safe and healthy communities – permitting more resilient, sustainable and livable structures for generations to come.
The IPC and IMC are revised on a three-year cycle through the Code Council’s highly respected consensus code development process that draws upon the expertise of hundreds of plumbing, mechanical, building and safety experts from across North America. With updates every three years, building codes allow for ongoing consideration of new technologies and scientific understandings.
“It’s critical for our codes to adapt to new building practices, technologies and societal needs. Our 2021 IPC and IMC take these needs into consideration and aim to promote safety above all else,” said Code Council Chief Executive Officer Dominic Sims, CBO. “Construction is ever-evolving, and how we prepare trades professionals matters more now than ever.”
The IPC is a pragmatic, apolitical, and technology-based look at the code that gives me a much bigger toolbox to choose from,” says All Area Plumbing senior project executive Damon Premer, a featured guest on the ICC Pulse Podcast. “Instead of being restricted to one way of doing things, with the IPC I have options and I can customize to the best quality for that project. The IPC gives me code proven ways to accomplish things that other codes lack.”
International Plumbing Code
The IPC establishes safety standards for health, safety, property protection and public welfare by prescriptive and performance provisions for the design, construction, installation, quality of materials, location, operation and maintenance or use of plumbing equipment and systems. 2021 additions/updates include:
- Multiple-user toilet facilities to serve all genders are now permitted.
- Two new methods for relining/rehabilitation of existing sewers have been added.
- Accommodations for mounted rooftop solar panels over vent terminals have been added.
- CSA B805/ICC 805 Rainwater Harvesting Systems is now allowed as an alternative design method.
In 2019, the Code Council commissioned a comprehensive independent analysis of the costs and savings associated with building under the IPC. The study found that over a 12-year period, counties that used the IPC saved $38 billion in construction costs and emitted one million fewer tons of carbon dioxide. The savings that resulted from use of the IPC contributed to national efforts to improve housing affordability.
International Mechanical Code
The IMC establishes minimum requirements for mechanical systems using prescriptive and performance-related provisions. It is founded on broad-based principles that make possible the use of new materials and new mechanical designs. 2021 additions/updates include:
- Clothes dryer exhaust terminals are now required to be at least three (3) feet from any opening into a building.
- Polyurethane spray-applied foam on the exterior of ducts in attics and crawl spaces is now required to meet specific smoke and flame index limits.
- Fire and smoke dampers must now be provided with approved access for inspection and maintenance.
- Refrigerant tables now include new refrigerants.
The 2021 IPC and IMC are currently available for pre-order and will be widely available in print and digitally in March. Related provisions of the ICC A117.1-2017 Standard for Accessible and Usable Buildings and Facilities will be included as a resource in the 2021 IPC. To pre-order the 2021 IPC and IMC, visit:
