Welcome to the "dungeon" known as the data center. I remember my first day reporting to the data center operations team three years ago. Even though I was a 10-year veteran of construction and commissioning who had seen it all, I have to confess... I was intimidated. (Laughs) "Is this the same HVAC I used to know?" "If I make a mistake here, will it make the national news?" That feeling of your heart racing with half-excitement and half-anxiety—you’re probably feeling it right now, aren't you? Once I actually got into it, I realized the skills I learned while breathing in dust at plant sites didn't just disappear. However, this thing called a "data center" definitely has a different personality than a typical building; it is much more prickly and sensitive. Working as a Lead Engineer, whenever I saw juniors falling into a state of "mental breakdown" with the exact same expression I once had, I would see my own reflection from three years ago. "Man, I had to learn the hard way by banging my head against the wall, but I want to teach these guys so it hurts a little less for them." This lecture was created with that single thought in mind. I’ve already gone ahead, experienced the trial and error you'll face, and even put together a complete "incorrect answer note" for you. I have packed in all the know-how from my 17-year engineering career—mixed with my blood, sweat, and refrigerant. So, please feel free to dig in, tear it apart, and savor every bit of it. If you ever think, "What on earth does this mean?" while studying, don't hesitate to ask on the bulletin board or via email. I will come to answer you faster than a UPS (Uninterruptible Power Supply) and with more energy than an emergency generator. Now, shall we get started?

🛠️ [Course Introduction] "Real" HVAC Scheduling from an 18-Year Veteran Do you know what task takes up the most time and causes the most stress when working at a construction site? It is **'schedule revision.'** In the past, I also spent countless nights drafting HVAC construction and commissioning schedules. Construction sites are prone to delays due to unexpected variables, so wrestling with schedules every month—or even every week—was my daily routine. Looking back, the real reason I struggled so much was that **'no one ever properly taught me.'** There was no basic training on how HVAC relates to other trades or how to actually calculate the time required for construction or commissioning. Consequently, the schedules I spent so much time creating often lacked the accuracy needed to be useful on-site. Then, I had a great opportunity to receive intensive training on scheduling. Once I understood the principles, I honestly felt a bit frustrated. I realized that it’s quite simple once you know the core concepts, and I had wasted so much time during projects simply because I didn't know the method. Ultimately, a construction project is a battle of 'resource management.' The three most important resources to manage on-site are materials, manpower, and equipment. Schedules are created to manage these resources efficiently and are immediately revised when changes occur to prevent delays in the overall construction period. In other words, the schedule is a critical document that serves as the standard for overall project management. While large construction companies may have dedicated scheduling teams, practitioners in each trade must fundamentally be able to draft their own schedules. This is because the schedules of each part come together to form the massive framework of the entire project schedule. That is why I have prepared this course, packed with the practical insights I've gained from 18 years in the field. • Scheduling Basics: What types of schedules exist on-site, and what/how a practitioner should draft them. • HVAC-Specific Practice: Scheduling examples and exercises tailored to actual HVAC work, from representative duct installation to commissioning. • Know-how to Avoid Trial and Error: Tips to stop wasting precious time on meaningless schedule revisions like I did. If my explanation is insufficient or if you get stuck while studying, please do not hesitate to ask questions at any time. Just like an HVAC system that must run 24/7, I will be standing by to provide reliable answers to your questions!

🚨 "Automatic control? Oh, that headache-inducing stuff?" If that was your reaction, come on in! Does the mere mention of "automatic control" give you a throbbing headache? Don't worry, that's perfectly normal! LOL. To be honest, I was the same way. Casting my mind back 17 years to my rookie days when I didn't know the first thing about automatic control... I suddenly landed a job at a foreign company dealing with factory automation systems. My naive fantasy that "the company isn't a school, so seniors will kindly spoon-feed me everything" was shattered into pieces. Expecting a 'kind mentor' from seniors whose souls were being drained by a daily deluge of work was a luxury. In the end, I had to learn the hard way by digging into thick manuals on my own, grasping concepts one by one through blood, sweat, and tears. The result of enduring and grinding through it all? I grew into a seasoned 18-year veteran engineer, leading HVAC construction and commissioning for major overseas projects like Kuwait Oil Company, Abu Dhabi National Oil Company, and Saudi Aramco. ✌️ 💡 Take the shortcut with the know-how I gained from my struggles! I poured everything into this course for juniors and seniors who, like me, are full of passion to grow but feel lost on where and how to start. I'll be honest. I won't lie and say, "Take this one course and you'll be an automatic control master tomorrow!" However, I am confident that once you finish this course, you will have a more solid and clear foundation than anyone else regarding "Ah, so this is what automatic control is!" and "This is how all the gears mesh together!" 🌐 Regardless of your major, automatic control is now a 'must-have survival item'! AI, IoT, autonomous driving, smart factories... the world is changing so fast these days, right? We've reached an era where it's hard to work properly without an understanding of automatic control. For electrical engineers, monitoring systems like EPMS and SCADA are basic setups! Mechanical engineers have also become inseparable from control systems like BMS and FMS. Data center engineers? They have to handle systems with dizzying names like EPMS, BMS, DCIM, and DCOS. While we can't perfectly dissect these complex-looking systems from 1 to 100, I will use my 18 years of experience to explain the **'core functions' and 'basic structures'** they must possess in a way that is far more intuitive and easy to grasp than anyone else. ⚡️ On standby 24/7! Questions are always welcome. If you find yourself tilting your head in confusion or thinking, "What on earth does this mean?" while taking the course, don't suffer alone! Feel free to knock on my door anytime via the bulletin board or my email. Just like an Uninterruptible Power Supply (UPS) that provides power without stopping for a single second, I'll always be waiting here to support you. 🔋 I hope my fierce survival story becomes a powerful weapon in your level-up journey. Now, shall we go smash through the headache of automatic control together? Let's go! 💖
