Commercial system experts see flow as a key step to optimizing system efficiency. Cutting down required tubing size, insulated PEX for district systems, and variable-speed pumps to pin down a chiller’s exact needs are three points of attack in the modern campaign against waste.

In light commercial hydronic systems, design challenges may be solved by using a fixed Delta-T (DT), variable-speed circulator as the main pump. Or with larger, whole-building hydronic systems that heat and cool, a constant-circulation strategy that moves large volumes of Btu’s while permitting fancoil units to tap the “river’s flow” can save precious thermal energy. Fancoil design, pumping stations, and these contemporary updates on proven hydronic concepts can all contribute to your system efficiency.

The new police training facility in Columbus, OH offered a variety of spaces, which you’d expect, and a slightly odd shape, which you might not. The situation warranted a custom piping and boiler configuration, and engineers produced an arresting design that fulfills its duty to tomorrow’s officers.

As part of the city’s move to drastically upgrade its ability to host major gatherings, this boiler/hydronics design had to be ready for large crowds and surprisingly cold days. By combining simplicity with flexibility, the new system moves the project closer to LEED® certification and boasts a range that can offer service from exhibit hall to symphony hall.

The Millennium Tower Residences in Battery Park face both the Hudson River and tough neighborhood sustainability standards. This article focuses on the selection and performance benefits of the heat pumps within the overall design, from giving each family accountability for conserving energy to the critical issue of minimizing noise. They have been an important but single step among many in pursuing the Gold standard near Manhattan’s southernmost patch of green.

This air transport firm takes over when “overnight” won’t do. They’ve delivered hearts on ice, special ops experts, rare animals, and radioactive payloads. A smartly assembled heating and snowmelt system at its Ohio hangar keeps performance high when temperatures get low.
