Chilled Beam

RMH provided mechanical and electrical engineering services for the LEED Gold-certified CAB Barracks Complex at Fort Carson, Colorado—a $94.9 million design-build project supporting the 13th Combat Aviation Brigade. From the outset, the team prioritized energy efficiency, livability, and cost-effective delivery to achieve net-zero energy performance.

Spanning 370,156 square feet, the complex includes three H-shaped, four-story buildings with apartment-style units for 994 soldiers. The design integrates advanced sustainable systems to reduce energy consumption and enhance occupant comfort.

Key energy-efficient features include:

  • Radiant heating and cooling with active chilled beams
  • Heat recovery chiller and 5,000-gallon thermal storage tank
  • Dedicated outdoor air systems with heat recovery ventilation
  • Solar thermal panels that meet 30% of domestic hot water demand
  • Gravity thin-film shower drain heat exchangers
  • 400 kW ground-mounted photovoltaic arrays offsetting 25% of annual energy use
  • Vacancy and occupancy sensors for lighting control
  • Automated window sensors and LED lighting throughout

RMH also engineered the adjacent Central Boiler and Chiller Facility (CBCF), which supports the barracks and future development on the Butts Field Plateau. The CBCF includes six condensing boilers, three 400-ton chillers, and over 81,000 feet of hot and chilled water distribution piping.

This project set a new benchmark for sustainable military housing and supports Fort Carson’s transformation into a net-zero energy installation.

The National Center for Atmospheric Research (NCAR) Wyoming Supercomputing Center (NWSC) in Cheyenne represents a significant leap in our understanding of climate, weather, and Earth processes. Designed with a flexible, modular approach, the facility houses next-generation supercomputing systems up to 1,000 watts/SF. It supports researchers in crucial tasks, such as visualizing future climate scenarios and tracking hurricane paths. With a commitment to low energy performance, the NWSC achieves a Power Usage Effectiveness (PUE) of 1.08, positioning it among the top 1% of the most efficient data centers globally.

To capitalize on Cheyenne’s unique cool, dry climate, RMH engineers used evaporative cooling towers to provide sufficient cooling for NCAR’s supercomputing equipment for 96% of the year. A 150′ x 8′ ultra-low-energy fan wall cools air-cooled equipment on the data center floor. Waste heat from the supercomputer is reused to heat administrative areas and melt snow on walkways and loading docks. Additionally, a chilled-beam system delivers efficient cooling in administrative spaces, while ultra-efficient water-saving technologies achieve savings of up to six million gallons annually.

The facility encompasses 153,000 square feet, featuring modular data storage, a visitor center, and a 100,000-square-foot central utility plant. Furthermore, eco-friendly design elements, highlighted by LEED Gold certification, affirm the NWSC’s dedication to environmental stewardship and sustainability. This groundbreaking center advances scientific research and promotes energy efficiency and conservation on a grand scale.
