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...

SBA 559: How to Coordinate with Electrical and Mechanical Contractors
The Smart Buildings Academy Podcast | Teaching You Building Automation, Systems Integration, and Information Technology
In this episode of the Smart Buildings Academy Podcast, we tackle one of the most common sources of friction on a controls project: coordination between electrical, mechanical, and controls teams. As a building automation professional, you often sit directly between multiple trades. When responsibilities are unclear, a missing connection or misunderstood scope can quickly become a schedule problem, a budget problem, and eventually a relationship problem. This episode explores how you can approach those coordination points earlier and gain better visibility into the interfaces that affect your...

SBA 558: IP Security Fundamentals
The Smart Buildings Academy Podcast | Teaching You Building Automation, Systems Integration, and Information Technology
Building automation systems are more connected than ever. That connectivity brings new capabilities, but it also changes what you need to know to design, install, and maintain them responsibly. In Episode 558 of the Smart Buildings Academy Podcast, we explore IP security fundamentals through the lens of building automation. You’ll get a practical framework for thinking about where vulnerabilities can emerge, how building networks differ from traditional IT environments, and why cybersecurity is becoming a core competency for controls professionals. If IP addresses, VLANs, firewalls, remote...

SBA 557: Valve Sizing 101
The Smart Buildings Academy Podcast | Teaching You Building Automation, Systems Integration, and Information Technology
A control valve can look right on paper and still create control problems in the field. For building automation professionals, valve sizing directly affects what you see at the controller. Unstable loops, limited valve travel, poor response, and persistent comfort complaints may appear to be programming or tuning issues when the real problem started with valve selection. In Episode 557 of the Smart Buildings Academy Podcast, Valve Sizing 101, you’ll learn how to think about control valves as precision control elements rather than simple devices for passing water. Understanding what happens...

SBA 556: Reading Catalog Sheets for Technicians
The Smart Buildings Academy Podcast | Teaching You Building Automation, Systems Integration, and Information Technology
Most building automation professionals have done it. Open the catalog sheet, find the wiring diagram, glance at it, and move on. What if the information you skipped is the reason a device works perfectly or becomes the next callback? This episode explores one of the most overlooked skills in building automation. Learning how to read a catalog sheet goes far beyond wiring. It helps you catch problems before installation, evaluate substitutions with confidence, and make better technical decisions throughout a project. Topics Covered • Why the catalog sheet is one of the most important...
