Beyond the blueprint: Navigating codes, carbon and clean energy incentives

How are codes, incentives, and carbon awareness shaping today’s building systems?

Building codes are becoming stricter, carbon targets are becoming law, and there’s more funding available for compliance. For those in plumbing and mechanical trades, system design now involves meeting emissions goals, leveraging incentives, and navigating changing regulations.

Some hydronic heating systems use slab-on-grade floor heating combined with an air handler or fan-coils in other areas of a building. This approach is also used for heated basement floors combined with a “hydro-air” delivery system for the main living areas.

Check valves explained: Understanding different types and applications in backflow prevention

Learn about check valve types (swing, ball, diaphragm, dual-plate) and their crucial role in backflow prevention.

Check valves are found in and around a pump system, a sump pit, or cracked open a main line. They’re everywhere. And there’s a reason they’re there: to prevent backflow. Backflow isn’t just unpleasant—it’s a serious hazard. It occurs when water or other liquids flow in the opposite direction, contaminating clean systems.

Zoning has always been a premier benefit of hydronic heating and cooling systems. There are many zoning configurations capable of delivering heat (or cooling effect) when and where it’s needed in a building, with minimal effect on the temperature in other parts of the building. Some methods use circulators to create flow in each zone; others use either motorized or thermostatic valves to regulate flow.

No slips, no shutdowns: ensuring access with snow melt systems

How radiant snow melt systems are transforming winter safety around the U.S.

Slip-and-fall accidents are among the most common liability claims in winter, according to AAA. Winter storms have cost billions of dollars in insured losses, just in the past few years. For businesses, that’s a major issue. In healthcare facilities where patient safety and uninterrupted access are non-negotiable, the stakes are even higher. Radiant snow melt systems can eliminate surface ice before it becomes a hazard, dramatically reducing legal exposure.

The hybrid heat advantage: decarbonizing water heating for a resilient future

Hybrid water heaters are becoming the default choice in jurisdictions racing toward net-zero.

Hybrid systems offer a critical bridge in the transition from fossil fuel reliance to full electrification. For contractors working in colder climates or retrofitting older homes, all-electric heat pump systems can be a tough sell. Hybrid units, however, deliver measurable emission reductions while preserving consistent output and adaptability.

One of the most powerful parts of the trip was witnessing how personal stories and local successes resonate with policymakers. Whether it was a community's struggle with water quality or the adoption of cutting-edge conservation practices, these conversations helped bridge the gap between policy and lived experience.
