SBA 569: Digital Twins for Buildings - Separating Practical Use from Hype
The Smart Buildings Academy Podcast | Teaching You Building Automation, Systems Integration, and Information Technology
Digital twins promise to transform building operations, but how much of that promise translates into measurable results? If you work in building automation, you've likely seen impressive digital twin demonstrations featuring interactive 3D models, real-time equipment data, and advanced analytics. But what does it actually take to turn those capabilities into tools that building operators can trust and use? In Episode 569 of the Smart Buildings Academy Podcast, David McDowell explores the gap between digital twin marketing and real-world implementation, drawing on firsthand experience...

SBA 568: Estimating Owner Direct BAS Work for Sales
The Smart Buildings Academy Podcast | Teaching You Building Automation, Systems Integration, and Information Technology
Estimating owner-direct BAS projects comes with a unique challenge: What happens when there are no drawings, no specifications, and no clearly defined scope of work? Unlike plan-and-spec projects, owner-direct work requires you to uncover the project's requirements before you can accurately estimate the cost. Missing information, uncertain equipment conditions, and unexpected labor demands can quickly turn a promising opportunity into a project that eats away at your margins. In Episode 568 of the Smart Buildings Academy Podcast, you'll explore what it takes to estimate owner-direct BAS...

SBA 567: Tuning a PID Loop
The Smart Buildings Academy Podcast | Teaching You Building Automation, Systems Integration, and Information Technology
Is your PID loop constantly hunting, responding too slowly, or struggling to maintain a stable setpoint? For building automation professionals, PID tuning can be one of the most challenging parts of optimizing HVAC control systems. What looks like a simple tuning issue could actually involve mechanical problems, changing loads, or multiple control loops working against each other. In Episode 567 of the Smart Buildings Academy Podcast, discover what it takes to move beyond trial-and-error adjustments and approach PID tuning with a repeatable, systematic process. Whether you're commissioning a...

SBA 566: Integrating Audio Visual Systems into BAS
The Smart Buildings Academy Podcast | Teaching You Building Automation, Systems Integration, and Information Technology
Your building automation system may be missing valuable information that already exists elsewhere in the building. What happens when your BAS and audio visual (AV) systems operate independently, even though both are designed to support the same spaces? Conference rooms experience unnecessary heating and cooling, occupancy data goes unused, and facility teams are left troubleshooting comfort complaints that could have been avoided. In Episode 566 of the Smart Buildings Academy Podcast, we explore the opportunities and challenges of integrating AV systems with building automation systems. For...

SBA 565: Proper Labor Estimation for Sales
The Smart Buildings Academy Podcast | Teaching You Building Automation, Systems Integration, and Information Technology
A building automation project can look profitable when it is sold and tell a very different story when it closes out. Often, the problem is labor. Hardware costs are relatively straightforward to quote. Labor requires judgment. If that judgment misses part of the work, overlooks site conditions, or relies on assumptions that no longer match reality, those missing hours can quickly consume project margin. In Episode 565 of the Smart Buildings Academy Podcast, you’ll explore how to approach labor estimation so the number reflects the work your team will actually perform. If you estimate, sell,...

SBA 564: What a PID Loop is Really Doing
The Smart Buildings Academy Podcast | Teaching You Building Automation, Systems Integration, and Information Technology
When a PID loop starts hunting, a valve keeps swinging, or a space refuses to settle at setpoint, changing tuning values can feel like the obvious next move. But what if the PID loop is not actually the problem? In Episode 564 of the Smart Buildings Academy Podcast, you’ll get a practical look at what PID loops are really doing inside building automation systems. Instead of treating PID settings like mysterious numbers, this episode helps you understand how the controller responds to what it sees and what the behavior of a loop can tell you about the system around it. You’ll also explore...

SBA 563: Preparing for Effective Service Calls
The Smart Buildings Academy Podcast | Teaching You Building Automation, Systems Integration, and Information Technology
A service call can start going wrong before you ever arrive at the building. A vague work order. Missing credentials. No clear site contact. The wrong tools. No understanding of what changed before the complaint started. For building automation professionals, preparation can be the difference between spending hours chasing symptoms and arriving on site ready to troubleshoot with purpose. In Episode 563 of the Smart Buildings Academy Podcast, we explore how to approach service calls with more structure and discipline. You’ll hear how experienced technicians prepare before they roll out,...

SBA 562: Estimating Electrical Loads for Secondary Power Loops
The Smart Buildings Academy Podcast | Teaching You Building Automation, Systems Integration, and Information Technology
A secondary power loop can look completely healthy while creating problems that technicians chase for months. A valve struggles to reach the set point. A controller randomly reboots. An actuator behaves inconsistently. Nothing trips, and the panel looks normal. If you work in building automation, these symptoms can point to an electrical load problem that was built into the system long before the service call arrived. In Episode 562 of The Smart Buildings Academy Podcast, you’ll learn how to think through secondary power loops before installation and how to evaluate existing loops when...

SBA 561: Database Fundamentals
The Smart Buildings Academy Podcast | Teaching You Building Automation, Systems Integration, and Information Technology
Databases sit behind more of your building automation work than you might realize. Every time you pull trend data, investigate an alarm, restore a system, review an audit trail, or move information between platforms, a database is part of the process. For building automation professionals, understanding database fundamentals can help you troubleshoot more effectively, plan systems more confidently, and have better conversations with IT teams. In Episode 561 of the Smart Buildings Academy Podcast, we break down databases from a building automation perspective. You’ll learn what’s happening...

SBA 560: Damper Sizing 101
The Smart Buildings Academy Podcast | Teaching You Building Automation, Systems Integration, and Information Technology
A control loop that hunts all day may not have a controls problem. The real issue could have been locked into the system before the controller was ever programmed. In this episode, we dig into damper sizing and why this often-overlooked mechanical decision matters to building automation professionals. Incorrect damper sizing can show up as poor comfort, wasted energy, premature actuator failures, noise, and unstable control. Knowing what to look for can help you distinguish between a programming issue and a mechanical problem that tuning alone will never solve. Topics Covered • Why damper...
