🛑 STOP DOING THESE 3 PREVALENT MISTAKES IN GROW ROOM HVAC SYSTEM DESIGN | We sell and support commercial indoor agriculture HVAC equipment and controls in grow rooms nationwide and are seeing trends. In this video, Tony Mormino shares the three most common mistakes regarding equipment sizing and grow room HVAC equipment selection. Grow room HVAC calculations require specific attention to: 🔢 the plant quantity, 💧 water rates, 💡 lighting schedule, 🌱 lighting types, 👉 and many other factors unique to indoor growth. The most common mistakes are missing the required dehumidification load, not understanding the room sensible heat ratio, and selecting off-the-shelf air conditioning equipment vs. commercial grow room air conditions, aka grow room dehumidifiers. Plants are not people; load calculations for #Cannabis grow rooms differ from typical commercial applications. 💴 Mistakes are common and costly; this video will offer insight into some issues to be aware of. Find a link to the full Grow Room HVAC Basics Video in the chat. 👇 If you are building a new grow facility or have an existing one needing help maintaining temperature and humidity, let's have a chat. #hvac #hvacdesign #buildingperformance #hvacsystems #IndoorAirQuality #FacilityManagement #energy #HVACcontrols #hvacmaintenance #EfficientComfort #HVACExpertise #commercialhvac #airconditioning  #energysolutions #energyefficiency #heatingandcooling #BuildingOperations #HVACequipment #growroom #cannabiscultivation #cannabiscommunity #humidity #cannabisgrowers #cannabisbusiness #cannabisindustry #cannabisgrow #cannabisgrows #indooragriculture

Join me for a deep dive into energy management with Lee Raspberry, CTSBO, BEAP, AEM, the Director of Construction and Planning for Bastrop Independent School District. In this episode, Lee shares his insights on integrating AI and machine learning into building automation systems. We discuss how it's advancing energy efficiency and creating optimal learning environments for students in the K-12 space. Some key takeaways from our discussion: -Strategic conservation and sustainability initiatives create substantial cost savings for districts. -Artificial intelligence and machine learning will significantly enhance HVAC controls, energy efficiency, and overall building operations, paving the way for smarter, more adaptive facilities management. -Certifications and professional development programs are critical for those in the FM sector to implement successful initiatives in their districts.

Before the internet we, or at least I, relied on my good ole' Modern Refrigeration textbook, notes, and instructor handouts to provide insite in areas or topics that were not covered, or not retained. Well, a lot has changed since those days. From Means and Methods to Technology, and a thing called the internet, don't even bring up the topic of refrigerants. Yet, the areas that have not changed are Thermodynamics and Electrical Fundamentals. These are the core concepts one must have a high proficiency in to be highly successful. I tell all of my students to save and archive the information I provide. You cannot remember every detail. It doesn't matter if it is electronic or hard copy. If it's a hard copy, scan it, retain it. I incorporate about an hour into the program on organizing files, creating folders and subfolders. I provide a file with all the manufacturers listed in folders, then a series of organized sub-folders by equipment types within the manufacturer. I take it further by providing recommendations on how to rename the files within the subfolder to facilitate better organization. This has a positive impact on search results when you are looking for the files. As I start to age out towards retirement (what that looks like, I don't know. My father was still teaching unitl two years ago), I realize I have amassed a huge amount of books, technical manuals and other resources. While I never want to trash a book, some are just simply outdated, but it is interesting to read through some of these older publications. Today I just look at a manual for a 1962 Tonrac. As I downsize and a pass the knowledge on, I am also searching for someone to mentor that has the same level of passion and love of the trade, and has the desire to teach and impart that knowledge to others. Here is page 1 of a MIMEOGRAPH (Heck, when was the last time you heard that term, most are clueless) AC/R Handout from 1978 that was provided by Gene Manco. HVAC Instructor at Delaware County Intermediate Unit . Mr. Manco was there from the early days of the Vo-Tech programs and Delaware County Intermediate Unit, a Skilled Trades Program Model that this country needs to return to, not what they currently operate.

ICYMI 💡 Our first series broke down the “Uberization of HVAC." "HVAC contractors know how to deliver home solutions that make a massive difference in the lives of their customers. But the bars for connectivity, convenience, cost, and perhaps most critically — transparency — keep getting raised higher and higher from the outside in. If given the option to install a heat pump with Airbnb-level choice at Uber-level speed for an Amazon-level price, who among us could hold out for long?" Read here🔸↓🔸 https://lnkd.in/djHQJV5f

In my experience, one of the most under-utilized data points in Soft FM strategy is occupant feedback specifically linked to cleaning effectiveness. While traditional metrics like cleaning times and square footage cleaned are valuable, they don't necessarily tell the whole story about the quality of cleaning. Here's why occupant feedback on cleaning effectiveness is crucial: 1.Targeted Cleaning: It can highlight areas where occupants perceive cleaning as inadequate, allowing for targeted adjustments and improved resource allocation. 2.Data Validation: It can validate (or challenge) data collected through other means, providing a more holistic view of cleaning efficacy. 3.Improved Satisfaction: Addressing occupant concerns directly fosters a sense of responsiveness and enhances overall satisfaction with the facility. Here's how we could improve access to this data point: A.Regular Satisfaction Surveys: Implementing short, targeted surveys that ask occupants about their satisfaction with cleaning in different areas. B.Interactive Feedback Systems: Exploring mobile app solutions or online portals where occupants can easily provide feedback on cleaning quality. C.Focus Groups: Organizing facilitated discussions with occupant representatives to gather detailed insights and suggestions. By incorporating occupant feedback on cleaning effectiveness into our data analysis, we can develop a more comprehensive picture of cleaning performance and optimize practices to truly deliver a clean and comfortable environment for occupants. What are your thoughts on this, and are there other under-utilized data points you find valuable? Share your insights in the comments! #SoftFM #Facilitymanagement #FMstrategy #FMconsulting

PSYCHROMETRIC CHART FOR HVAC ANALYSIS | Why are "Psychrometric Charts" important? CHOOSING THE RIGHT SIZE: The chart helps us figure out how much cooling or heating is needed to make the air inside a building feel just right. It's like picking the right size of jacket for the weather outside. UNDERSTANDING AIR CHANGES: The chart shows us what happens to the air when we cool it down, warm it up, add moisture (like a humidifier), or remove moisture (like a dehumidifier). It's like a map that shows us how the air changes. SAVING ENERGY: By looking at the chart, engineers can find ways to make the air conditioning and heating systems work more efficiently. This means using less energy, which is good for the environment and saves money. KEY FORMULAS & CONVERSION FACTORS TO REMEMBER: Atmospheric pressure = 29.921" Hg. at sea level 1 BTU = Amount of heat required to raise (or lower) the temperature of one pound of water 1°F 1 ton of refrigeration = 12,000 Btu/hr = 200 Btu/min 1 watt = 3.414 Btu/hr 1 horsepower = 2545.6 Btu/hr 1 ft (head) = 0.433 psi (at 62°F) 1 boiler horsepower = 33,475 Btu/hr Air changes per hour (N) in a space N = (60 x CFM) / space ft 3 CFM = airfow rate (ft 3 /min) Water quantity (GPM) required for heating and cooling GPM = q / (500 x Δt) q = load in Btu/hr t = water temperature Chiller capacity (Tons) Tons = (GPM x Δt) / 24 GPM = gallons per minute of chilled water t = water temperature Psychrometric charts are like a special tool that helps HVAC engineers understand and control the air around us. They make sure we stay cool in the summer, warm in the winter, and always comfortable inside our homes, schools, and almost every other type of building. 💡 PRO-TIP: Download and then print this off on 11x17 paper for maximum benefits, oh, and don't forget to share by reposting, please.
