Project Name:
 Yeon Building

Location: 522 SW 5th, Portland OR

Owner: Jonathan Rose Companies

Architect: SERA

General Contractor: Andersen Construction Company

Overview:

At 123,000 sq ft and 15 stories, the Yeon Building was the tallest building in Portland when it was constructed in 1911 and has been listed as a National Historic Place since 1994. In 1970, Hunter-Davisson installed a then state-of-the-art air conditioning system, which served the Yeon Building for over 40 years. This recent project involved a complete mechanical system replacement and upgrades to modernize the Yeon and make it competitive in Portland’s “Class A Historic” office market again. Hunter-Davisson looks forward to another 40 years of providing valued services to this building.

Highlights

  • Designed and installed a complete mechanical system upgrade to the building including replacing all of the major mechanical components.
  • New cooling tower and high-efficiency boilers and condenser water pumps were increased in capacity to include the first 3 floors.
  • Entire mechanical system was upgraded with a state-of-the-art Honeywell DDC Building Management System.
  • A complex weekend crane lift shutting down two blocks resulted in the replacement of the Cooling Tower, 2 Boilers, Circulating Pumps, and the additional of an Emergency Generator.
  • The new circulating pumps were up in 3 days, followed by the completion of the cooling towers and boilers, resulting in only minor disruptions to the tenants.
