(4:50) Kevin outlines LEAN and its two critical principles: throughput and waste. Throughput is the time it takes for a process or operation to complete. From administrative to payroll, to inventory, and production - all sources of build-up. Identifying waste throughout an operation is what LEAN aims to do to reduce waste. Kevin gives an example of throughput at a factory with visuals. There are three Japanese terms for waste; Muda is the first term and encompasses overproduction, waiting, transporting, overprocessing, motion, inventory, and defects. The second term is Mura and encompasses unevenness, meaning ups and downs of scheduling for orders and what is produced. The third term is Muri, which encompasses overburden and is difficult to see as waste because it is visible in equipment or machine downtime and overburdening workers.

[12:10] Kevin discusses how waste build-up can lead to chaos, instability, time mismanagement, and the failure to address problems as soon as possible. Overall, no value to add.

[13:44] Kevin describes the tiers in detail and gives an example of how he utilized the four tiers: standard work, visual management, accountability meetings, and discipline.

[22:17] Accountability meeting: an opportunity to set a timeline, track metrics, and an opportunity to give or ask for help and resources. How often they occur depends on the actions and their frequency. Kevin stresses the importance of ensuring action will take place after goals are set during a meeting.

[25:23] Discipline—what are our roles as managers/leaders? If we set up our process correctly, we should run it correctly, and the metrics will come in. A second-level layered process audit helps manage a process by nipping an issue in the bud, whether it's an employee hesitant to do something due to lack of training or being overburdened.

[27:30] What does a tiered management structure look like? Kevin goes into detail about each tier and its designated role in problem-solving. Overall, the tier system ensures a standardized way of managing escalations and helps bring them down.

[3:52] Will describes what being a Certified Air Filtration Specialist (CAFS) means to NAFA and why air filtration professionals should consider receiving the certification. The benefits are numerous, including the credibility needed to stand out in today's market, the ability to remain up to date and evolve with the industry and its technology, and the potential for increased sales numbers as well-informed problem solvers and certified guides for customers in air filtration products. Wills’ pro tip for companies is to attach the earning potential of their sales team to becoming certified, further incentivizing the process.

[11:25] Will and Sharon discuss the two levels of NAFA certification, the Certified Air Filter Specialist (CAFS) and the NCTII. They explain the rapid implementation of techniques and best practices that these certifications offer. The program and guide only forces companies or professionals to specialize in something other than something. Installation knowledge is essential - air filtration is only as good as how it was installed.

[17:17] The Clean Air Awards are based on a comprehensive points system that evaluates various aspects of a company's commitment to clean air. This system encourages companies to participate as an internal incentive for professionals. Winning this award is an excellent opportunity for companies to solidify partnerships with the customer and their facility. The mentality among manufacturers holds them back from utilizing NAFA certification opportunities to help them stand out as credible professionals.

[25:04] Statistics show that the Clean Air Awards are not as widely examined as they could be, and the number of active Certified Air Filter Specialists (CAFS) per company is relatively low. This presents a significant opportunity for companies to stand out and demonstrate their commitment to clean air. Planning for the future should involve inclusive efforts to network with customers who value a clean air award.

Growing crops indoors allows farmers to control many production variables, including water, nutrients, lighting, and climate. Keeping the air free and clear of contaminants also improves crop quality and yield and helps to ensure consumer and food safety. Many indoor farmers use a combination of air filters, air purification systems, and good sanitation practices to avoid and eliminate mold spores, bacteria, VOCs, chemicals, and other potential sources of contamination in their facilities. In this presentation, Dr. Sabeh will review the efficacy and necessity of using various technologies that are commonly used and sometimes misused in indoor plant environments, including cannabis.

For detailed show notes, read below and use the timestamps to navigate the episode:

[6:03] Dr Nadia begins with an introduction to the indoor farm and what defines it; she describes the many types that exist to date and the many names it goes by. She showcases the array of crops possible with indoor farms, including but not limited to leafy greens, herbs, microgreens, and even certain fruits and vegetables.

[9:43] Indoor farming has numerous benefits. It allows for a high crop density, conserves water, reduces waste, and enables eco-friendly pest management. Evolving technology maintains an ideal indoor space, maximizing profitability while minimizing risk and ensuring consumer safety. This has sparked a new era of sustainable and efficient farming.

[11:41] Dr. Nadia defines a controlled environment as variables such as pests, climate, and irrigation that can be controlled.

[12:09] Dr. Nadia explores the critical role of HVAC (Heating, Ventilation, and Air Conditioning) systems in indoor farming. Firstly, these systems maintain optimal temperature, humidity, and air movement, which is crucial for plant growth. Secondly, HVAC systems play a vital role in controlling air quality. Plants require specific levels of carbon dioxide and other gases to grow, and some gases like ethylene and formaldehyde can be harmful to plants in particular doses and at different times of the year. Additionally, plant-emitted gases such as Cannabis odor can be challenging to measure, but they can be filtered out at low concentrations to improve air quality. Particulates such as dust and smoke can also harm crops, mainly if neighboring facilities do not filter their air. Finally, Dr. Nadia describes how insect pests and plant pathogens can threaten crops and how they can be transmitted.

[25:26] Dr. Nadia breaks down the technologies and techniques for providing clean air to crops based on the plants' needs. The top priorities are managing CO2 levels to provide for crops and sustain worker health exposure to CO2. Dilute infected air is essential. Particle filtration is possible due to variances in screen sizes and MERV filters. HEPA is only useful for people because plant viruses are transmitted by contact, not air. Dr. Nadia discusses irradiation, ozonation, odor control, and room pressurization. She highlights the importance of sanitation and maintaining a clean environment for good air quality.

[39:02] Q & A session with Dr. Nadia.

[1:50]
Mr. McGrath begins the overview of recent 52.2 upgrades in the last five years with the MERV Table for better progressions and shedding data for testing filters. He then moves on to updates for relative humidity and narrowing down the range of percentages. For the optical particle counter, updates were more terminology-related.

 

[5:11]
Mr. McGrath explains the goal of repeatability and reproducibility with graphs outlining how filters are tested for efficiency across different labs. Improvement should revolve around the grouping of data points for the particle diameter.

 

[5:43]
Mr. McGrath introduces the most recent project, Research Project 1784, in which samples were filtered across multiple labs to determine whether lab testing standards vary. These results will assess changes in ASHRAE standard 52.2.

 

[7:37] Mr. McGrath examines the removal of MERV 17 and what led to that reference removal, as well as MERV 18, 19 and 20 references.

 

[10:04] Recent Upgrades to 52.2 in the last year or two, including the addition of PM 52.2 filter efficiency based on a flat distribution curve and using E-values.

 

[13:31] The recent COVID-19 pandemic led to
changes in ASHRAE 52.2 Addendum C, which helps collect filter efficiency data for viruses and bacteria. Calculations were created to determine the presence
of the organism and its ability to grow. Variety in organisms detected is still needed due to organism resistance.

 

[17:00] Mr. McGrath concludes with current
52.2 pursuits that revolve around unifying terminology for testing and parameters for checking devices. Research project 1784 is ongoing, and its results will lead to new upgrading projects.
