⚡ Is Your Building Using More Energy Than It Should?

High energy costs can be a symptom—not the root of the problem.

Inefficient equipment, poor controls, incorrect settings, air leaks, and systems running when they don’t need to can quietly drive up operating costs over time.

At Prasino Engineering, we help uncover the issues behind energy waste so building owners and facility teams can make smarter, more informed decisions.

Because energy efficiency isn’t just about using less energy.

It’s about making your building work better. 🌱

🏢 Your building is always telling you something. The question is—are you listening?

Unusual temperature changes, rising energy use, equipment cycling too often, moisture, or systems that just don’t seem to perform as they should can all be clues to a bigger issue.

At Prasino Engineering, we go beyond the symptoms. We investigate how building systems actually perform in the field, connect the dots, and help uncover the root cause—so you can make smarter decisions with confidence.

Because good engineering isn’t about guessing what went wrong.
It’s about finding out why.

🔍 Listen to your building. Understand its performance. Protect your investment.

A building can look perfect on paper—and still underperform in the real world.

The difference is in what happens after the plans become reality.

From HVAC performance and controls to energy use and overall system operation, every detail matters when the goal is a building that truly performs as intended.

At Prasino Engineering, we help uncover what’s working, what isn’t, and what can be improved—so building owners and project teams can make better decisions with confidence.

Because a successful project isn’t just one that gets completed.

It’s one that works.

Power Systems. Protected. Performance Assured. ⚡

Short Circuit Current & Time Current Coordination Studies are critical to designing safer, more reliable electrical systems.

At Prasino Engineering, our studies help identify potential fault conditions, verify protective device coordination, and ensure electrical equipment and personnel are better protected from overcurrent events.

🔹 System Safety — Protect equipment and personnel
🔹 Code Compliance — Support NEC® and industry standards
🔹 Optimized Design — Improve protection and minimize unnecessary downtime
🔹 Accurate & Reliable — Detailed analysis you can count on

Because a properly coordinated electrical system isn’t just about keeping the power on—it’s about making sure the system responds safely, efficiently, and reliably when it matters most.

⚡ What happens when an electrical fault occurs?

A strong electrical system isn’t just about delivering power—it’s about knowing how your system will respond when something goes wrong.

At Prasino Engineering, our Short Circuit Current & Time-Current Coordination Studies help you understand fault conditions and ensure protective devices operate in the right sequence.

🔌 Short Circuit Current Studies help determine available fault current and verify that electrical equipment is properly rated for the system.

⏱️ Time-Current Coordination Studies help ensure the protective device closest to a fault operates first—reducing unnecessary outages and protecting critical equipment.

The result? Safer systems. Better coordination. Greater reliability.

Don’t wait for a fault to expose a weakness in your electrical system. Plan for the unexpected.

Does a heated slab really need insulation under the entire slab? 🤔

The answer depends on which energy code you’re following.

While the 2024 IECC requires R-5 full under-slab insulation for all heated slabs, ASHRAE 90.1-2022 generally requires perimeter insulation only. Understanding the difference can impact your project’s cost, constructability, and code compliance.

Heated Slab Insulation - IECC vs ASHRAE 90.1

At Prasino Engineering, we simplify complex energy codes so architects, engineers, and building owners can make informed decisions with confidence.

Code knowledge isn’t just about compliance—it’s about building smarter.

We’re excited to share a major milestone! 🎉

Our continuing education course, Decoding the 2024 IECC & ASHRAE 90.1-2022 (PE26IECC00), has officially been approved by the American Institute of Architects (AIA)!

This achievement reflects Prasino Engineering’s commitment to providing meaningful education that helps architects and industry professionals navigate evolving energy codes and building performance standards.

We’re looking forward to sharing this course with the AEC community. Stay tuned for upcoming session dates!

Before a single wall goes up, energy modeling tells the story of how a building will actually perform. ⚡

At Prasino Engineering, we use energy modeling to help owners, architects, and contractors compare system options, hit code compliance targets, and avoid costly surprises down the road. It's how we close the gap between design intent and real-world performance — before construction even begins.

Smart design starts with smart data. 📊
