Your Proprietary BAS Contract Is Costing You More Than You Think
Service contracts, parts markups, software licenses, and locked-in vendor pricing add up to 40-60% more in total cost of ownership over 10 years. Here is how to calculate what proprietary lock-in is actually costing you and what the path out looks like.
What Is a Sequence of Operations and Why Does Your Building Need One
A sequence of operations is the written document that tells your controls programmer exactly how every piece of equipment should behave. Without one, you are guessing. Here is what a good SOO includes and why it matters more than the hardware.

Utility rebate programs pay more when you pair LED retrofits with controls. Here is what Entergy and CLECO programs require, which controls qualify, and the mistakes that cost building owners rebate money they already earned.
Niagara N4 Trend Data: What to Log, How Long to Keep It, and How to Use It
Most Niagara systems trend more data than anyone looks at, or less data than anyone needs. Here is a practical framework for what to log, at what interval, how long to retain it, and how to actually use it.
Cybersecurity in Building Automation: It Is Not Just an IT Problem
Building automation systems are increasingly targeted by cyberattacks, and most are not ready. Here is what building owners and facilities teams need to know about BAS cybersecurity, from network segmentation to BACnet/SC.
Static Pressure Reset: The Energy Savings Strategy Nobody Talks About
VAV systems running at fixed static pressure setpoints waste fan energy most of the operating year. Here is how static pressure reset works, why the fan affinity laws make it so powerful, and how to implement it correctly.
Protocol Gateways Explained: How We Connect Old Systems to New Ones
A protocol gateway translates between communication protocols, letting legacy HVAC controllers talk to modern BAS platforms. Here is how gateways work, when to use them, and when to replace the controllers instead.
Alarm Management: How to Stop Ignoring Your BAS Alarms
Most BAS installations generate hundreds of alarms per day that operators have learned to ignore. Here is how to fix that through alarm rationalization, priority levels, routing logic, and analytics.
The Numbers Behind Pneumatic-to-DDC Conversions: What the Research Actually Shows
Industry estimates suggest that between 20 and 70 percent of commercial buildings still rely on pneumatic controls. DOE-funded research from PNNL found that properly implemented building controls could cut commercial energy use by 29 percent. Here is what the data says about the real costs and savings.
Understanding the 2024 IECC Energy Code Changes for Commercial Buildings
The 2024 International Energy Conservation Code includes expanded controls mandates, new fault detection requirements, and stricter ventilation rules. Here is what building owners and engineers need to know.
Preparing Your Building Controls for Hurricane Season
Hurricanes Ida and Katrina taught Louisiana facilities teams hard lessons about BAS resilience. Here is the pre-storm checklist, what happens to your controllers during power loss, and how to bring systems back online safely.
Niagara N4 Graphics That Actually Help Your Operators
Bad BAS graphics create confusion and slow down response. Good ones get operators to the right information in three clicks or fewer. Here is how we design Niagara N4 HTML5 graphics that operators actually use.
Integrating Lighting Into Your Building Automation System: Why and How
Lighting is often the last system to be integrated with a BAS, but the case for doing it is strong. Coordinated scheduling, single-dashboard management, and demand response capability all depend on lighting being part of your controls architecture.
Demand-Controlled Ventilation: Stop Paying to Cool Empty Rooms
Most buildings bring in the same amount of outdoor air whether 5 people are in a room or 50. In Louisiana's humid climate, that unnecessary ventilation costs real money. Here is how DCV works and what the ROI looks like.
The Controls Technician Shortage Is Real: What It Means for Building Owners
Qualified BAS and DDC technicians are harder to find every year. Here is what is driving the shortage, how it affects service costs and response times, and what building owners can do to protect themselves.
