Get stuck in – Michael Bourgeois, CWT How do standards get written in ways that working water treaters can actually meet? In this conversation, AWT Past President, current Related Trade Organization (RTO) Committee Chair, and Chemco Products Company Operations Manager, Michael Bourgeois CWT, explains how AWT's liaisons collaborate with peer organizations, so guidance reflects field reality—operations, risk, and achievable compliance. From Field Bags to Board Rooms: Why RTOs Matter Bourgeois outlines the purpose of AWT's RTO structure: volunteer liaisons track and influence work at groups whose missions overlap with industrial water—CTI, ABMA, ASHRAE, AWWA, ASHE, and others. The aim is simple and practical: make sure member voices are heard so guidance advances health outcomes (e.g., Legionella control) and day-to-day feasibility for service providers and suppliers. Turning Reaction into Proaction Historically, the industry learned about new rules after they landed. Bourgeois details how AWT is shifting to co-authoring cooling-water guidelines with CTI and re-engaging ABMA, so boiler-water limits and methods reflect current technologies and operations. The model: clarify shared goals, contribute content expertise, and formalize collaboration so members get usable documents at member pricing. Concrete Moves: Boiler Water, Healthcare, and More Examples include AWT's role on ABMA's Boiler Expo steering committee (with a focused water-treatment training block) and early conversations with ASHE on pathogen control in building and healthcare water systems. He describes how liaisons feed updates into a formal committee cadence, so the AWT Board and members see progress—not just headlines. When working professionals help write the playbook, outcomes improve clients, operators, and public health—and members stop "reacting" to standards they had no hand in shaping.

With those words, Jemma Tennant highlights one of the most profound differences between Legionella management in Europe and the United States. In this episode of Scaling UP! H2O, host Trace Blackmore welcomes Jemma Tennant, Chair of the Water Management Society (WMSoc), to explore how legislation, enforcement, and professional training shape the fight against Legionella. Proactive Regulation and Duty of Care The UK treats Legionella as a foreseeable and preventable risk. Jemma explains how laws like the Health and Safety at Work Act and COSHH Regulations require mandatory Legionella risk assessments, temperature monitoring, and written control schemes—even when no cases have occurred. This contrasts with the U.S., where ASHRAE 188 serves as guidance rather than enforceable law, often triggering enforcement only after outbreaks. Jemma shares a case study where a housing association was fined £1.2 million despite no recorded illness, underscoring the UK's proactive stance on protecting public health. Hospitals, Design, and Emerging Challenges From hospital plumbing layouts to new “waterless” intensive care units, Jemma details how design choices can either mitigate or magnify waterborne risk. Scotland's model of involving water safety groups at the design stage provides a proactive example for healthcare worldwide. She also outlines how climate change, net-zero initiatives, and rising ambient temperatures are complicating control strategies across Europe. Raising Standards Through Collaboration As Chair of WMSoc, Jemma is leading efforts to raise industry standards and reverse what she calls a “race to the bottom.” She describes partnerships with AWT in the U.S. and LMAG in Australia to share expertise across borders. The episode also explores her pursuit of the Certified Water Technologist (CWT) credential and her vision for adapting the certification for UK professionals. Conclusion This conversation is a call to action for water treatment professionals everywhere: regulations, standards, and collaboration matter. Whether in cooling towers, hospitals, or housing estates, Legionella management requires vigilance, shared knowledge, and a commitment to raising the bar.

“Rules written in a panic rarely stand the test of time.” In this encore episode, Trace Blackmore welcomes back Patsy Root, Senior Manager of Government Affairs at IDEXX Water and active member of the AWT Legislative and Regulatory Committee. Patsy brings global data, case studies, and clear recommendations for smarter Legionella regulation — and why a targeted focus on Legionella pneumophila can save both lives and resources. From Outbreaks to Proactive Policies Patsy unpacks a central truth: most regulations emerge reactively, often after a high-profile outbreak. Drawing on her research from the U.S., Canada, and Europe, she compares different jurisdictions' approaches — from Quebec's targeted testing mandate to New York City's broader species-based rule — and reveals why some frameworks reduce cases far more effectively than others. The Case for Targeted Testing Legionella encompasses around 60 species, but not all carry equal risk. Patsy explains why L. pneumophila — the species most responsible for Legionnaires' disease — demands priority in monitoring and control. Through examples from France, Germany, the UK, and beyond, she demonstrates how focusing on the pathogen itself, rather than all species, leads to measurable public health gains and cost savings. Educating Lawmakers and Industry Beyond technical data, Patsy emphasizes the importance of water professionals engaging with legislators. She outlines how clear communication, evidence-based recommendations, and standards like ASHRAE 188 can guide practical, enforceable rules. Her advice balances science with real-world feasibility, helping both regulators and facility managers protect health without unnecessary expense. This conversation is more than a policy discussion — it's a blueprint for better public health protection through smart, focused water management. Whether you work in compliance, operations, or advocacy, Patsy's insights will equip you to engage in the legislative process with clarity and authority.

"Just because you have a water management plan doesn't mean it's working." That's the hard truth Matt Freije, founder and CEO of HC Info, delivers in this episode of Scaling UP! H2O. As the architect behind LAMPS — a leading cloud-based platform for water management programs — Matt joins Trace Blackmore to explore the critical evolution of water safety, compliance standards, and real-world implementation challenges facing facilities in 2025. Beyond the Binder: Water Management Plans That Actually Work In an era of heightened awareness and shifting regulations, simply checking the compliance box is no longer enough. Matt walks us through the CDC data and ASHRAE findings that make a strong case for active, ongoing water management — not just documentation. Drawing from recent outbreak investigations, he explains why implementation, not content, is often the root failure. Trace and Matt discuss the widespread misconception that water management plans guarantee zero Legionella. They also address the real barriers preventing facilities from taking action — from budget limitations to internal roadblocks — and what water professionals can do to influence smarter, risk-based decisions. Regulatory Pressure, AI Integration, and What's Coming Next With ASHRAE 514, AAMI ST108, and ASSE 12080 gaining ground, the water industry is seeing increased scrutiny, especially in healthcare and hospitality facilities. Matt outlines how these evolving standards are transforming expectations and forcing a shift in accountability. The conversation takes a forward-looking turn as they explore the power of AI and aggregated analytics to optimize pathogen control. With 10,000 buildings in the LAMPS system, HC Info is preparing to offer data that could shape public health outcomes nationwide — a move that could redefine how we benchmark performance and interpret Legionella test data at scale. Culture, Purpose, and Long-Term Vision As a mechanical engineer with an epidemiology background, Matt also reflects on the human side of leadership — from building a values-driven team to embracing his faith as a cornerstone of decision-making. His message for water treaters is clear: “Either do it well or don't do it.” For facilities leaders, his advice is to stop fearing complexity and start leveraging the tools available — because water management done right can improve not just compliance, but health outcomes, asset longevity, and operational resilience. Conclusion This episode is a masterclass in how to future-proof your water safety strategy. With actionable insights, emerging technologies, and a clear call to accountability, Matt Freije reminds us that smart water management is both a technical responsibility and a moral imperative. Listen to the full conversation to understand how new standards, digital tools, and intentional leadership are shaping the future of water safety.

Building HVAC Science - Building Performance, Science, Health & Comfort
“IAQ is no longer just a maintenance issue—it's a strategic lever for improving patient outcomes and financial performance in healthcare.” “Saving a single dollar in energy for a hospital is like generating twenty dollars in patient revenue.” “The big message: it's not as big a lift as it used to be. Smart IAQ solutions are now turnkey and data-driven.” In this episode of the Building HVAC Science Podcast, host Bill Spohn is joined by Renée Jacobs, a seasoned expert in healthcare construction and building automation. Renée shares her career journey from hands-on construction to leading the healthcare vertical at Distech Controls. Her passion for improving patient outcomes through smarter building systems shines as she explains how indoor air quality (IAQ) has become a pivotal factor in modern healthcare environments. Renée draws a compelling analogy between early skepticism of handwashing and today's evolving recognition of IAQ's role in patient health. She highlights how advanced sensors and smart building automation are transforming reactive facility management into a proactive, data-driven practice. One standout example she discusses is a hospital system that drastically improved both IAQ and energy management through Distech's Atrius platform, earning them a Better Buildings Award from the Department of Energy. The conversation also dives into key industry standards like ASHRAE 170, the hidden costs of inaction, and the importance of leveraging AI and IoT in HVAC systems to enhance both care and cost-efficiency. Renée wraps up by emphasizing that implementing smart IAQ solutions is no longer a daunting task—it's a strategic investment that is more accessible and turnkey than ever before.

Are You Ready to Talk About Legionella? Every August, we dedicate an entire month to a topic that touches public health, liability, and the core of what water treaters do — yet it's still misunderstood by many: Legionella. In this episode, Trace Blackmore kicks off Legionella Awareness Month by returning to the basics. Where did Legionella get its name? What makes it dangerous? And why is there still confusion between a water treatment program and a water management plan? Tracing It Back: History, Misconceptions, and Missed Conversations Trace opens with the 1976 American Legion outbreak in Philadelphia — the moment the medical and water treatment worlds collided. He explains how the bacteria was identified, how the term Legionella pneumophila came to be, and how Pontiac Fever and Legionnaires' Disease represent two ends of the same pathogenic spectrum. But more importantly, he challenges us to think critically about the language we use. Saying “Legionella” casually — without understanding whether we're referring to the bacteria, the illness, or the implications of a test result — can lead to major breakdowns in communication between service providers and facility managers. A Water Treatment Program Is Not a Legionella Plan Many professionals know how to deliver great chemical treatment. But too often, when a Legionella test comes back positive, the customer assumes the water treater is responsible. This episode explains how that misunderstanding happens—and how to prevent it through proactive, well-framed conversations. Trace walks through why seasonal testing is the bare minimum, what makes a good water management team, and why documentation and pre-approved action plans are essential for clarity and peace of mind when results come in. He also introduces tools like the CDC Legionella Toolkit, ASHRAE 188, and ASSE 12080—resources every industrial water professional should know and use. The Systems at Risk — And Why It's Not Just Cooling Towers Trace breaks down the environments where Legionella thrives cooling towers, stagnant pipes, dead legs, hot water systems with low temperatures, decorative fountains, humidifiers, and spas. He highlights why biofilm protection matters, why heat isn't always enough, and how mixing valves and plumbing design can support both safety and scald prevention. You'll hear how real-world scenarios unfold—and how one positive test, without the right planning, can lead to panic, blame, and liability risk for everyone involved.

Efrie Escott is the Decarbonization Technical Program Leader for Digital Energy at Schneider Electric. As a licensed architect and life cycle assessment practitioner, Efrie's previous experience in reducing carbon in the built environment was as an environmental researcher within the KieranTimberlake Research Group, where she was a core member of the development team for Tally, an award-winning BIM-integrated life cycle assessment tool.We had a lively conversation with Efrie about research in the built environment field, Tally, her leap to Schneider Electric, and what kind of impact she is having in that context (including a recently launched internal tool). We also got a little nerdy about ASHRAE standards and others and how they are addressing (and tabulating) whole life carbon. She celebrated the immense gains on technology and knowledge, but she also acknowledged her disappointment that we have not yet hit peak emissions. And she voiced a concern that seemed poignant this season, about how we need to bring more people along in the movement and the industry. “We are doing a great job accelerating the front end, but we need to work on the middle more," she said. "We need to spend more time talking to other people -- not just each other. This pains me, because I love spending time with people in this community. But if we are serious about really scaling the progress, we need to do a much better job bringing in others. The science tells us that we need to sprint the distance of a marathon. This means we need to carry each other, and we need to be intentional about who we are bringing into the work.”

In this short Q&A podcast, Bryan answers a listener-submitted question about apps for doing proper loads. Fred specifically asks about apps or charts that can help an HVAC contractor determine the insulation value of a home without assuming numbers or drilling into walls during load calculations. Load calculations account for all the ways that BTUs can enter or leave a home: conduction, convection, and radiation. Insulation prevents heat transfer via conduction, so it's important to the load calculation process. High-end HVAC design software like Wrightsoft and Kwik Model 3D will have these features built into them (based on the age and location of the home). ASHRAE's handbook also has tables and data with R-values and U-factors to help you out with Manual J load calculations. RED Calc is an app that allows you to calculate a wall's R-value with measurements, including surface and air temperatures indoors and outdoors. This RED Calc software is available through the U.S. Department of Energy, as is REScheck. The DOE insulation fact sheet is also quite valuable, as are The Engineering Toolbox and materials straight from the insulation manufacturers. The best way to get a comprehensive load calculation is to have a lot of tribal knowledge about how houses are built in your area, analyze energy bills, and combine tools like RED Calc with building performance tests. RED Calc is available through the U.S. DOE at https://basc.pnnl.gov/redcalc. REScheck is available at https://www.energycodes.gov/rescheck.

“It is a team effort to protect public health from Legionella.” - Alberto Comazzi, Ph.D. We are excited to welcome back Alberto Comazzi, Ph.D. of Sanipur US, for his third appearance on the Scaling UP! H2O Podcast. As an expert in waterborne pathogens, Alberto shares his invaluable insights and experiences about Legionella to help our audience stay informed and proactive in managing water systems. In this episode, we cover a wide range of topics from handling positive Legionella tests to the effectiveness of monochloramine in disinfection. Let's dive into the key points of our discussion. How do you handle a call from a client panicking about their first positive Legionella test? Alberto advises us to stay calm and follow the pre-established plan outlined in the Water Management Plan (WMP). First, review the WMP to understand the specific steps to take for this scenario. Consider the positivity rates and the location where Legionella was found. By following the agreed-upon plan, you can address the client's concerns effectively and ensure proper action is taken. Why have we seen Legionella increase by nearly ten times over the past few years? “5-6 years ago there wasn't much information about Legionella, and today so many people are interested in this field which protects public health.” - Alberto Comazzi, PhD Dr. Comazzi highlights two key factors behind the significant rise in Legionella cases: 1. Enhanced Water Testing and Awareness: The past few years have seen a substantial increase in both awareness and testing for Legionella. Healthcare professionals are now more informed about the risks of Legionella and are conducting more tests. Since 2017, the requirement for Water Management Plans (WMPs) in healthcare facilities has led to more comprehensive water testing, contributing to the rise in detected cases. 2. Increased Water Age in Buildings: Efforts to conserve water, which have important environmental benefits such as saving energy and reducing costs, have inadvertently led to higher water age in building systems. When water remains in systems for longer periods, it can lead to reduced disinfectant levels and higher water temperatures—conditions that promote Legionella growth. While water conservation is crucial, balancing it with effective Legionella control measures is essential for maintaining public health. By understanding these factors, we can better address and mitigate Legionella risks, ensuring a safer environment for everyone. What advice do you have for those putting together a WMP but who doesn't have the ASSE 1280 Certification? Get Certified or Seek Expert Help: Creating a comprehensive Water Management Plan (WMP) can be complex. While obtaining ASSE 1280 certification is highly recommended, you can also consider hiring a consultant to help you draft your plan. However, it's crucial to ensure that you execute and document the plan effectively. Proper training for facility operators on temperature control, flushing procedures, disinfectant management, and documentation is essential. “A Water Management Plan that's just sitting on the shelf isn't doing anyone any good. If no one implements the plan, it is useless.” Dr. Alberto Comazzi emphasizes, “Proactive measures are better and more cost-effective than reactive ones.” With upcoming due diligence plans addressing various waterborne pathogens, being prepared is key. Who has responsibility when it comes to municipal water? Alberto reminds us that there is a division between the municipality and the building. Municipal Water Responsibility: Municipal water suppliers are responsible for providing water that meets regulatory standards up to the distribution system. They conduct primary disinfection to inactivate most microorganisms and secondary disinfection to maintain a residual disinfectant. However, there are no enforceable limits for Legionella in the municipal water supply, and testing for Legionella is not required. Building-Level Responsibility: Once water leaves the municipal system and enters a building, the responsibility for water safety, including Legionella control, falls to the building owner or manager. Building environments, with their complex plumbing systems, cooling towers, and hot water systems, can foster Legionella growth. Therefore, effective management and control measures at the building level are crucial for ensuring water safety. Monochloramine vs. Chlorine: Which is better Disinfection and Legionella Control in Building Water Systems? Alberto highlights the advantages of monochloramine over chlorine: Case Study Results: A case study in San Francisco showed that switching from chlorine to monochloramine in the municipal water supply significantly reduced Legionella positivity rates in buildings—from 60% to 3-4%. This demonstrates the effectiveness of monochloramine in providing better overall disinfection due to its stability and ability to maintain higher disinfectant levels in building plumbing systems. Comparison with Chlorine: Monochloramine, unlike chlorine, is less reactive with organic materials in water and thus produces fewer regulated disinfection byproducts. It is a more stable disinfectant, which makes it less likely to form harmful byproducts while still providing effective disinfection. Effectiveness in Building Systems: In building water systems, especially those with low water usage or higher temperatures, monochloramine's stability is advantageous. It provides a more consistent and longer-lasting disinfectant presence throughout the system, reaching all areas effectively, which is crucial for preventing Legionella growth. What long-term effects on sustainability and equipment should we consider when balancing water conservation with the use of additional disinfectants in buildings? Alberto outlines key considerations: Corrosion Impact: When installing additional disinfectants, consider their potential to corrode plumbing systems. High levels of corrosive disinfectants can damage plumbing, so it's crucial to balance disinfection effectiveness with the preservation of the building's infrastructure. Water Quality Effects: Assess whether the chosen disinfectant might increase other harmful molecules in the water. Evaluate disinfection efficacy not only in the lab but also in real-world building settings to ensure it does not negatively impact overall water quality. Review Published Data: Refer to peer-reviewed literature and research from credible sources like the EPA to verify the long-term effects of disinfectants on water systems. Reliable data helps ensure that the disinfectant does not introduce unintended consequences and maintains water quality over time. How did monochloramine perform in controlling Pseudomonas compared to traditional methods? In a case study, monochloramine was implemented in facilities with Pseudomonas issues and proved effective in reducing colonization. "Unlike short-term solutions like flushing and hyperchlorination, monochloramine's stability allowed it to reach all parts of the distribution system, providing long-term control" shares Alberto.

We have the privilege of welcoming back Janet E. Stout, Ph.D., President of Special Pathogens Technology and the founder of Special Pathogens Laboratory, A Pace Laboratory. Dr. Stout has academic affiliations with the School of Public Health and Swanson School of Engineering at the University of Pittsburgh. A self-described "Legionellologist", Dr. Stout's more than 30 years of research has defined the epidemiology, microbiology and prevention approaches for controlling Legionella growth in building water systems. In our most recent interview, Dr. Janet Stout shared what was new with Legionella standards, what state health departments are doing to combat Legionella, and she answers your burning question of “Are Legionella cases truly on the rise” with data and statistics. This is a Legionella episode you cannot afford to miss, so let's scale up our Legionella knowledge with Dr. Stout. Also, don't forget to check out our free Legionella Resources page where we have listed all of the articles, standards, and tools mentioned in this interview. What Is New with Legionella Standards? How Does It Impact the Water Treatment Industry? Dr. Stout highlights several key updates: Association for the Advancement of Medical Instrumentation (AAMI) TIR34:2023 Published in Fall 2023, TIR34 focuses on water quality for reprocessing medical devices. Dr. Stout emphasizes, "The problem is infection. The solution is the quality of the water." "There are clear chemical and microbial parameters, and these healthcare facilities need your assistance, water professionals," Dr. Stout encourages. ANSI/AAMI ST108:2023 This new standard, “Water for the processing of medical devices,” emphasizes the critical role of monitoring water quality to prevent microbial proliferation. ST108 is a significant step forward for patient safety. “I see so many positive indications of progress and prevention, and that's good for everyone,” shares Dr. Stout. General Services Administration (GSA) Order PBS 1000.7A Effective in 2024, this order mandates comprehensive water testing across federal buildings to ensure health and safety. It includes stringent testing protocols for contaminants like Legionella. Compliance requires professionals to hold certifications such as ASSE 12080 or be certified industrial hygienists (CIH). Dr. Stout remarks, "It's such a big deal that you have to be ASSE 12080 certified to service government buildings now, I'm really impressed by GSA." American Water Works Association (AWWA) Guidance Set to be updated in 2024 or 2025, the new standard will replace AWWA C651-C652 and will likely be titled “Disinfecting Potable Water.” This new guidance will provide updated protocols for disinfecting water-storage facilities, so be on the lookout for this new one. ANSI/ASHRAE Standard 514:2023 This standard focuses on risk management for building water systems, covering physical, chemical, and microbial hazards. It provides comprehensive guidelines for designing, building, maintaining, and operating water systems to protect building occupants. Challenge to the Listener: Educate Yourself: Familiarize yourself with the latest standards, including TIR34, ST108, GSA Order PBS 1000.7A, and ANSI/ASHRAE Standard 514. Engage with Clients: Reach out to healthcare facilities and federal buildings to offer your expertise in water management and help them navigate the new requirements. Stay Informed: Keep an eye on updates from organizations like AAMI, ASHRAE, GSA, and AWWA to stay ahead of industry changes. What's Going on in Ohio? Will Other States Follow Ohio? Ohio's Proactive Approach Dr. Janet Stout praises Ohio's innovative approach to managing Legionella risks. Unlike most areas where Legionella water management is voluntary, Ohio has taken a significant step by mandating it through hospital licensure codes. This mandate requires hospitals to have a water management plan and to test for Legionella, making compliance a condition for maintaining their licenses. The new regulation, scheduled to take effect in October 2024, aims to enhance infection control and manage the risk of waterborne pathogens, particularly Legionella. High Incidence of Legionnaires Disease Ohio's proactive stance is partly driven by its high incidence of Legionnaires disease. The state, along with Maryland, Pennsylvania, and New York, consistently reports high numbers of cases. Ohio's health department has noted a significant increase in cases from 2022 to 2023. This alarming trend highlights the urgent need for effective water management and testing protocols. The Ohio Regulation Specifies Detailed Requirements for Hospitals: Each hospital must conduct Legionella testing within the first twelve months. Two validation tests must be performed, no fewer than four months apart and no more than six months apart. The regulation includes explicit language to ensure rigorous water management and Legionella testing. The Future for Other States Dr. Stout is hopeful that other states will follow Ohio's example. She mentions ongoing legislative efforts in states like New Jersey and Pennsylvania, although the process is slow. Ohio's innovative and mandatory approach to Legionella water management sets a precedent that could influence other states. Dr. Stout's optimism reflects a broader movement towards more stringent and proactive water management practices across the country. As more states recognize the importance of these measures, we can expect a gradual but significant shift towards better management of Legionella and other waterborne pathogens. Are Legionella Cases Truly on the Rise? "Legionella is on the rise," Dr. Stout shares. "It's not increasing just because we are doing more testing." She also points to changing weather patterns as a contributing factor. "There's a global shift with Legionnaires' disease cases extending from summer into fall. The season is getting longer, and things are staying warmer longer." This observation highlights the need for a deeper understanding of how environmental factors and public health practices influence Legionella prevalence. We hope you found these insights from Dr. Janet Stout valuable. Legionella management is a critical aspect of industrial water treatment, and staying informed and proactive is key to ensuring the safety and health of building occupants. As always, we encourage you to continue learning, sharing, and growing within our community. Thank you for being a dedicated member of the Scaling UP! H2O community and for celebrating Legionella Awareness Month with us. Together, we can make a significant impact in the fight against Legionnaires' disease.

Hello Scaling UP! Nation, August is Legionella Awareness Month, and we're excited to bring you in-depth insights on this crucial topic. Usually, we bring you four episodes every August, but this year, you're in luck! With five Fridays this month, we have five episodes packed with valuable information for you. Today, podcast host Trace Blackmore, CWT, is here to answer your pressing questions about Legionella. As industrial water treaters, you are the heroes in the fight against Legionella, protecting your communities and clients against this dangerous bacteria. Scaling up your Legionella knowledge is a great way to celebrate Legionella Awareness Month, and to support you, we've created a free Legionella resources page at www.ScalingUpH2o.com/Legionella Understanding Legionella: Common Questions Answered What is the difference between Legionella and Legionnaires' disease? Legionella is a bacteria responsible for Legionnaires' disease, a type of pneumonia that comes from getting ill after being exposed to Legionella. It thrives in water and poses significant health risks. Legionnaires' disease was discovered in the mid 1970's after several attendees of the American Legion convention got sick after attending the convention. How does a person get Legionnaires' disease? Inhaling water contaminated with Legionella bacteria can lead to infection. What are the symptoms of Pontiac Fever or Legionnaires' disease? Early symptoms mimic the flu, but more severe pneumonia-like symptoms can develop. Look out for high fever, cough, difficulty breathing, chills, and diarrhea. How common is Legionnaires' disease? Per the CDC, in 2015 there were approximately 6,000 cases reported in the United States. Who is at higher risk for developing Legionnaires' disease? While most people have resistance, fewer than 5 in 100 exposed individuals may develop the disease. High-risk groups include older adults, smokers, and those with weakened immune systems. How does Legionella enter buildings? Legionella enters through a building's makeup water. This is why we need to test the water coming into a building's system and also set up a program to test within the system so we know what to do and respond appropriately if a test comes back positive for Legionella bacteria. What promotes Legionella growth? Biofilm, temperature fluctuations, inadequate disinfectant levels, and water stagnation within building water systems can promote Legionella growth What are Water Management Programs (WMPs)? WMPs are designed to identify hazardous conditions and minimize the growth and spread of waterborne pathogens, including Legionella, in building water systems. How Should I Discuss Legionella Testing Frequency with a Client Who Only Wants to Test Once a Year? When discussing Legionella testing with a client who only wants to test once a year, emphasize the importance of more frequent testing for safety and compliance. Here's how to approach the conversation: Encourage Regular Testing: I always encourage people to test for Legionella at least every season or quarter. Regular testing helps identify potential issues early, ensuring the safety of your water system. Refer to the Water Management Plan (WMP): It's crucial to refer back to your Water Management Plan (WMP) to understand the necessary steps if a test comes back positive for Legionella bacteria. Develop a Comprehensive Plan: Let's come up with a plan outlining what we are going to test, how often we will test, and how we will use the data. We should also decide how to handle positive results, particularly for different Legionella species. Taking some time to plan upfront will streamline the process when collecting water samples. By emphasizing the benefits of regular testing and a proactive approach, you can help clients understand the importance of more frequent Legionella testing and the value of a detailed WMP.

"Be curious, maintain an open mind, and maintain your high standards." - Lee Bainbrigge Our water treatment community is a close-knit brotherhood and sisterhood, regardless of where we live. We face similar challenges and share a common goal: to grow and learn from each other. Our latest podcast episode features a conversation that delves into the differences and similarities in Legionella control practices and regulations between the United States and the United Kingdom. This insightful episode features Lee Bainbrigge, Chief Sales and Marketing Officer of SMS Environmental Ltd as our charming lab partner. Key Insights from Lee Bainbrigge on Legionella Control: Differences in Legionella Management and Documentation In both countries, the primary Legionella control methods are keeping water moving and using temperature control. However, the UK places a stronger emphasis on documentation and compliance systems to record control measures. "The types of control you are using, you need to record it, you need to write it down in a compliance system," Lee explained. If a system tests positive for Legionella, it is crucial to effectively and clearly communicate to the client, "There's Legionella in the system. Let's look at doing something about it." In the UK, these communications are meticulously documented and kept as digital records for future reference. Crafting Effective Legionella Legislation When discussing what lawmakers should consider when writing Legionella legislation, Lee advised caution and balance. He noted that the guidance in the USA is relatively proportionate and effective when in the right hands. "Effectively, the guidance you've got in the USA is relatively proportionate... In the right hands, you're going to do a good job with the guidance that you've got," he noted. In contrast, the UK's approach can sometimes be overly prescriptive. Lee suggests a middle ground, advocating for guidance that is neither too relaxed nor too stringent, ensuring efforts and resources truly reduce risk. "I think the most reasonable guidance you could come up with is somewhere in between the two. There are pros and cons on both sides," Lee mentioned. ASHRAE 188 and Its Direction in the USA Lee affirmed that the USA is on the right track with ASHRAE 188 for Legionella control. "Yes, absolutely!" he responded when asked if the US is heading in the right direction. He highlighted the importance of competent professionals conducting Legionella risk assessments to ensure effective control measures. "Make sure that the people that are carrying out your Legionella risk assessment are competent and you're actually getting good advice at the beginning of your control scheme," he advised. Challenges and Technology Opportunities in the UK In the UK, current challenges include maintaining competency and training within the industry, adapting to novel systems like heat pumps, and dealing with reduced water flow in buildings. Lee mentioned the potential of new technologies, such as the Internet of Things (IoT) and remote monitoring, which could revolutionize Legionella control, although current guidance has yet to fully incorporate these advancements. "We have got challenges with... new novel systems coming into our domestic hot and cold water systems. The use of heat pumps and different ways of sourcing energy and reducing water flow are all having an impact on Legionella control," Lee explained. Building a Global Culture of Learning Lee is a strong advocate for collaboration within the industry. He believes in learning from each other and sharing best practices, which can greatly benefit organizations and improve public health protection. "I'm a big believer of us being collaborative in this industry," Lee shared. "When we see what somebody else is doing and establish what's working for organizations, that is just so great to see." Professional Standards and Certifications Lee discussed the significance of the Certified Water Technologist (CWT) certification. SMS Environmental Ltd. values high standards and depth of knowledge within its team, which is why they are strong proponents of the CWT certification. "We don't have in the UK an equivalent qualification specific to water treatment," Lee explained. "We've certainly looked at the CWT and gone, 'this does really what people that have been involved in the organization in the industry far longer than me tell me was very much the way the sector was born.'"

Shelby Breger, co-founder of Conduit Tech, joins Bryan Orr on the HVAC School Podcast to discuss her company's innovative lidar-enabled design and sales software tool for HVAC contractors. Conduit Tech's software utilizes lidar sensors in iPads and iPhones to scan homes and create 3D models and 2D floor plans. It overlays load calculations factoring in property data, orientation, cooling/heating degree days, and building materials. This allows contractors to perform detailed load calculations on-site in just 15 minutes or less while engaging homeowners visually. Breger explains that the core goal is to empower contractors to deliver better-designed systems more efficiently while enhancing the customer experience. Homeowners get to see the level of work and customization involved, building appreciation for the contractor's services. The visuals help communicate potential comfort issues and how the proposed solution uniquely addresses their home's needs. Breger emphasizes that Conduit Tech is focused on solving fundamental industry pain points identified through continuous feedback from their contractor user base. The software has evolved to provide more flexibility to adapt to the realities of home visits. New features like augmented reality equipment visualization further enhance the customer engagement capabilities. Topics covered include: How Conduit Tech's lidar scanning and modeling works Using the software for room-by-room or whole home load calculations Integrating data sources like property records, ASHRAE design conditions, etc. Aligning with ACCA Manual J methodologies and certifications Improving load calculation accuracy through real-world monitoring Leveraging technology to streamline processes across sales, design, and installation The value proposition for contractors and homeowners Roadmap for adding features based on user feedback How contractors can get started with Conduit Tech's software Contractors interested in trying out Conduit Tech can visit https://www.getconduit.com/, or they can email shelby@getconduit.com or info@getconduit.com to learn more and schedule a demo.

In this short podcast episode, Bryan talks about the four different combustion venting categories for gas appliances as set by ASHRAE and where you'll see them. He also shares some notes about pressurization. These categories deal with the pressurization and temperature ranges of the vents. Category 1 venting is used for old-school open-combustion gas furnaces; they have high flue gas temperatures and are considered low or mid-efficiency furnaces. This venting category is not positively pressurized, and it has a single-wall flue and operates more like chimneys, as the appliance is usually under negative pressure; a draft is created and draws the flue gas out. It's non-condensing, negative-pressure venting. Category 2 venting is not common anymore; they operate with negative pressure in the vent, and condensation is still likely. Category 3 venting is non-condensing positive-pressure venting. These are more common in older through-the-wall appliances. Category 4 venting is condensing, positive-pressure venting for high-efficiency or condensing gas appliances with lower-temperature flues and sealed combustion. PVC is the most common venting material for these furnaces. We can recover some energy from the condensation process.

In this podcast, Bryan Orr interviews Jesse Stewart from NAVAC about A2L refrigerants and compatible tools and safety procedures. They discuss how NAVAC has a full line of A2L-compatible tools for evacuation and recovery, including the new NR7 and upgraded models of the NRDDF and NRDD. Jesse explains key features that make tools A2L compatible, like DC motors, sparkless designs, insulated electrical terminations, soft power switches, and fans. He notes that NAVAC has been designing tools this way in preparation for wider A2L adoption. The conversation covers some evolving questions around A2L systems, like requirements for strike plates to protect line sets and whether existing line sets can still be used. They agree that ongoing questions need to be directed to organizations like ASHRAE to get definitive guidance. Overall, Jesse emphasizes that best practices are now required, not just recommended, when working with A2Ls. He details several examples, like nitrogen purging while brazing, the "10-foot rule" for checking potential ignition sources, and proper confined space protocols. Topics covered: NAVAC's line of A2L-compatible tools Key safety features for A2L tools Evolving regulations and best practices around A2L systems Using nitrogen while brazing The "10 foot rule" before A2L installations Working in confined spaces with A2Ls Adapting outdated practices to meet new safety needs Explore NAVAC's A2L-compatible tools at https://navacglobal.com/a2l-compatible-tools/ or general products at https://navacglobal.com/.
