Home to 11 federal agencies, the Byron G. Rogers Federal Office Building in downtown Denver was targeted by its owner, the U.S. General Services Administration, for an extensive modernization project to significantly improve energy efficiency and deliver advanced updates to this important example of 1960s-era Federal architecture. This design-build project involved comprehensive upgrades to all major building systems housed within the 18-story, 494,000-square-foot office tower and minor improvements to the adjacent courthouse. The upgrades are projected to reduce energy use in the office tower by nearly 70 percent relative to current levels.

In addition to improving building envelope insulation, the most significant energy savings were achieved by implementing a chilled-beam system to replace the building’s inefficient, inflexible mechanical system. A chilled-beam system is an advanced method for distributing heating and cooling throughout the building with minimal energy waste. It primarily uses water at a moderate temperature to condition building spaces. After capturing heat generated by building occupants, computers, lighting, and solar gain, a thermal tank in the basement stores and circulates this heat through the building’s chilled-beam system as needed.

The retrofitted building features additional energy-saving technologies, including 100% LED lighting, enhanced daylighting, and roof-mounted solar thermal collectors that provide all of the building’s domestic hot water. Water-conserving strategies are expected to reduce water use by 40 percent. The comprehensive modernization positions this Federal facility as a model for sustainable government building operations while preserving its architectural significance.

As the project’s mechanical, electrical, and plumbing engineer, RMH provided comprehensive MEP engineering services for this transformative modernization project.

RMH provided mechanical, electrical, and lighting design services for a high-performance cabinetry manufacturing facility featuring 80,750 square feet of production space, 97,000 square feet of warehouse, and 22,300 square feet of administrative offices.

To safely manage large volumes of combustible wood dust generated during production, RMH engineered a 1,800-linear-foot dust collection system with 50,000 CFM capacity. The system captures heavy wood particles at 47 high-velocity pickup points and delivers them to an exterior baghouse. During the winter, the system reclaims heat by returning filtered air to the building.

To mitigate explosion risks, multiple infrared spark detection and suppression devices within the ductwork are integrated into the design. At the baghouse, RMH designed a pressure-sensitive detection and chemical suppression system to enhance safety and compliance.
Our team also designed a 2,350-square-foot, Class I, Division 1 paint vault equipped with a hazardous exhaust system, specialized grounding, and dedicated power and lighting systems to support safe and efficient operations.

Breckenridge Brewery, at the time, Colorado’s fifth-largest craft brewer, unveiled a new $35-million brewery campus in response to growing demand and community engagement. Located in Littleton, the 79,150-square-foot, three-building complex blends rustic farmhouse aesthetics with modern brewing innovation and sustainable design. The campus includes:

  • Brewhouse Building: Featuring brewing and malt handling areas, a hops cooler, boiler plant, offices, conference room, and a tasting room.
  • Production Building: Home to fermentation, bottling, barrel aging, canning, kegging, dry goods storage, and a quality control lab.
  • Restaurant Building: A full-service restaurant with indoor seating, a lounge, a kitchen, and a gift shop.

Designed for scalability, the facility starts with a brewing capacity of 70,000 barrels annually, with potential to reach 300,000 barrels.
Sustainability was central to the design. Energy-efficient evaporative cooling supports process areas and the kitchen. Natural ventilation in the Brewhouse enhances indoor air quality. Destratification fans improve seasonal comfort, while 95%-efficient condensing boilers provide heating. A water reuse system captures and filters wastewater for landscape irrigation.

BYU-Idaho is Idaho’s largest private University, sitting on a 430-acre campus with a district heating loop providing space heating for 40 buildings. RMH served as mechanical, electrical, and controls engineer for this project to add cogeneration capabilities to the Rexburg campus heating plant. The University replaced its coal-fired boiler plant with a new, multi-leveled heating plant containing a combined heat and power (CHP) system using natural gas. The project began with a conceptual study/economic analysis, which investigated the economic viability of adding cogeneration capabilities.

After completing the conceptual study and economic analysis, RMH designed the installation of a nominal 5.7MWe natural gas turbine with a 50,000 pph HRSG, which has a calculated simple payback of eight years. RMH’s design for the gas turbine featured a fully enclosed evaporative cooling system to increase the turbine output, as well as a turbine enclosure heat reuse system.
