How to Cut Construction Costs with Smart Building Tech (At the Touch of a Button)

Based on the insights from PoE Texas

If you are planning a new construction project or a major renovation, one of the biggest hurdles you’ll face is the budget. Traditional electrical infrastructure is expensive, rigid, and heavy on materials.

In their video, "Cost Savings and Affordable Smart Building and PoE Technology at the touch of a button!", PoE Texas outlines a modern alternative that is changing the industry: Power over Ethernet (PoE).

This guide breaks down the educational concepts from the video and provides step-by-step instructions on how you can use this technology to lower both your Capital Expenses (CapEx) and Operating Expenses (OpEx).

What is PoE? (The Educational Basics)

Before diving into the savings, it is important to understand the tech. Power over Ethernet (PoE) allows you to send both electricity and data over a single, standard Ethernet cable (like Cat5e or Cat6).

Traditionally, a smart light fixture would need two things:

1. A power cable (hardwired to high-voltage AC electricity).

2. A control wire (for data/smart features).

With PoE, you only need one cable. This convergence is the secret sauce behind the massive cost savings.

Step-by-Step Guide to Saving Money with PoE

Based on the strategies shared by PoE Texas, here is how you can approach your next building design to maximize efficiency.

Step 1: Identify "Converged" Systems

The first step is to list the building systems that typically require separate power and data. In a traditional build, these are siloed. In a Smart Building, they should be converged onto your network.

• Lighting: LED lights are natively low-voltage DC. powering them with AC is inefficient.

• Window Shades: Motorized blinds can be powered by PoE.

• HVAC Controls: Thermostats and sensors.

• Access Control: Keypads, cameras, and locks.

Instruction: improved design starts by removing the high-voltage requirement for these devices. Plan to power them via your IT network switch rather than a breaker panel.

Step 2: Use the "Touch of a Button" Calculator

The video emphasizes the ease of planning ("at the touch of a button"). PoE Texas offers tools like a PoE Calculator to help you estimate your power budget.

• Calculate Power Budgets: Determine how many watts each device needs (e.g., a 15W light fixture).

• Select Your Switch: Ensure your network switch has the total power budget (e.g., 500W) to handle all connected devices.

Why this matters: This calculation helps you avoid over-provisioning expensive electrical panels and conduit that you don't actually need.

Step 3: Slash Your Material & Labor Costs

This is where the major "CapEx" savings happen. By switching to PoE, you eliminate significant traditional construction costs:

• No Conduit: Ethernet cables do not require the heavy steel conduit that high-voltage wires do.

• Less Copper: You are running lighter, cheaper cables.

• Faster Labor: Low-voltage cabling does not always require a master electrician for every single run, and it snaps together faster than hardwiring.

Real-World Stat: Projects can often see a 10-30% reduction in installation costs compared to traditional electrical work.

Step 4: Automate for Long-Term Savings (OpEx)

Once the system is installed, the "Smart" aspect kicks in. Because every light and sensor is on the network, you can control them centrally.

• Occupancy Sensing: Lights turn off automatically when a room is empty.

• Daylight Harvesting: Shades lower and lights dim automatically when the sun is bright.

Instruction: Set up your automation rules immediately after installation. This ensures you start saving on utility bills from Day 1.
