Idle pallets may seem harmless, but without proper sprinkler system design, they can become the most dangerous fire hazard in your building—here’s how the 2025 NFPA 13 addresses that risk.

UMDFPE Chair Arnaud Trouvé, Ph.D., presented Denhardt with the award at the Distinguished Alumni Dinner during NFPA’s 2025 Conference & Expo.

The new office serves as a regional base for its two subsidiaries: Henderson Engineers, whose focus is building systems design, and Henderson Building Solutions, which specializes in design-build construction management and commissioning.

Proper pipe sizing is more complex than it seems — and oversizing can be just as problematic as undersizing; Lance MacNevin explains how the PPI’s Plastic Pipe Design Calculator helps designers strike the right balance for efficient, safe plumbing systems.

Designing plumbing for building retrofits isn’t just about pipes — it’s a puzzle of past and present, where careful investigation, collaboration, and creative problem-solving turn old spaces into seamless, functional systems.

High-efficiency boilers promise big savings, but as Andy Williams explains, true performance depends on system design, emitter sizing, and maintaining return water temperatures below 130°F for maximum condensing efficiency.

Outdated ground heat exchanger (GHEX) design methods are driving up costs and complexity in ground-source heat pump (GSHP) systems. In part one of this two-part series, Albert Wallace introduces modern, modular best practices that optimize system efficiency, cut expenses, and improve long-term reliability.

Explore the latest updates from ANSI, ASME, CSA, and other leading code bodies as Ron George, CPD, recaps key plumbing standards meetings and regulatory changes shaping the industry in 2025.

The International Code Council (ICC) is the leading global source of model codes and standards and building safety solutions. 

Backflow assemblies don’t typically come to mind when trade professionals consider new and advanced or emerging technologies. Yet lately, advancements in all sectors of the plumbing and mechanical industry are moving swiftly.
