šŸ¢ Your building is always telling you something. The question isā€”are you listening?

Unusual temperature changes, rising energy use, equipment cycling too often, moisture, or systems that just donā€™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 causeā€”so you can make smarter decisions with confidence.

Because good engineering isnā€™t about guessing what went wrong.
Itā€™s about finding out why.

šŸ” Listen to your building. Understand its performance. Protect your investment.

A building can look perfect on paperā€”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 whatā€™s working, what isnā€™t, and what can be improvedā€”so building owners and project teams can make better decisions with confidence.

Because a successful project isnā€™t just one that gets completed.

Itā€™s one that works.

Power Systems. Protected. Performance Assured. āš”

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.

šŸ”¹ System Safety ā€” Protect equipment and personnel
šŸ”¹ Code Compliance ā€” Support NECĀ® and industry standards
šŸ”¹ Optimized Design ā€” Improve protection and minimize unnecessary downtime
šŸ”¹ Accurate & Reliable ā€” Detailed analysis you can count on

Because a properly coordinated electrical system isnā€™t just about keeping the power onā€”itā€™s about making sure the system responds safely, efficiently, and reliably when it matters most.

āš” What happens when an electrical fault occurs?

A strong electrical system isnā€™t just about delivering powerā€”itā€™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.

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

ā±ļø Time-Current Coordination Studies help ensure the protective device closest to a fault operates firstā€”reducing unnecessary outages and protecting critical equipment.

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

Donā€™t wait for a fault to expose a weakness in your electrical system. Plan for the unexpected.

āš” Is Your Building Using More Energy Than It Needs?

High energy costs can be more than just a line item on your utility billā€”they can be a sign that your building has opportunities to operate more efficiently.

At Prasino Engineering, we look beyond the numbers. Our Energy Audits & Energy Design services help identify energy-saving opportunities, evaluate building systems, and turn data into practical solutions.

šŸ”Ž Identify energy waste
šŸ’” Discover efficiency opportunities
šŸ“Š Understand potential savings
šŸ¢ Make smarter building decisions

Because better building performance starts with knowing where to look.

Letā€™s make your building more efficient, one opportunity at a time.

Does a heated slab really need insulation under the entire slab? šŸ¤”

The answer depends on which energy code youā€™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 projectā€™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 isnā€™t just about complianceā€”itā€™s about building smarter.

Weā€™re excited to share a major milestone! šŸŽ‰

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 Engineeringā€™s commitment to providing meaningful education that helps architects and industry professionals navigate evolving energy codes and building performance standards.

Weā€™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. āš”

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 ā€” before construction even begins.

Smart design starts with smart data. šŸ“Š

āš” Energy Audits Today. Lower Utility Bills Tomorrow.

Reducing energy costs starts with understanding how your building performs.

An energy audit helps uncover hidden inefficiencies that increase operating expenses, while strategic energy design ensures your building systems are optimized for efficiency, reliability, and long-term performance.

At Prasino Engineering, we help building owners, architects, and facility managers turn energy data into smarter decisionsā€”creating buildings that consume less energy, reduce operating costs, and perform at their best.

Because every watt saved is an investment in your buildingā€™s future.
