RMH modernized the mechanical and electrical systems at the historic St. John Vianney Theological Seminary in Denver, Colorado. Initially built in 1907, with additional buildings constructed during the Depression era, the seminary required thoughtful upgrades to improve energy performance and occupant comfort while preserving its architectural heritage.

RMH designed the upgraded lighting systems to meet current life safety and energy codes, enhance illumination, and simplify maintenance. Our team selected energy-efficient lamps and custom historic-style fixtures to maintain the campus’s character.

To install a large air handling unit in the chapel tower, RMH designed a lightweight, all-aluminum vertical unit. The unit was assembled and field-erected on site by lowering components through the bell tower to avoid exceeding structural load limits.

Because new ductwork would compromise interior aesthetics, RMH engineered a hydronic heating and cooling system. This approach minimized wall and ceiling penetrations while delivering high energy transfer efficiency.

In the library, which houses rare and historic books, the team was required to maintain strict temperature and humidity levels using evaporative cooling with chilled water backup. Leveraging Denver’s dry climate, the refectory kitchen and chapel use evaporative cooling. At night, the chapel is flushed with cool outdoor air to reduce daytime cooling loads.

Our design improved lighting efficiency by specifying LED and fluorescent fixtures, installing occupancy sensors, and using photocells to reduce energy use during daylight hours.
