ACCO Engineered Systems’ operational status and COVID-19 response >

Metropolis | Los Angeles, CA

The $1 Billion, 6.3 acres, 3.5M Metropolis project is one of the largest mixed-use developments on the west coast. Phase I included the 18-story, 350-room Hotel Indigo, and 38-story, 309-unit residential tower. Phase II included a 43-story residential tower with a 20-story mid-rise tower (515 Units) and a 65-story residential tower with a 26-story mid-rise (715 Units).

Project Requirements

From both a marketing and energy savings strategy, Metropolis Hotel and Residence were designed to achieve LEED Platinum standards.

What ACCO Delivered

Indigo Hotel: Due to budget constraints, ACCO went through considerable engineering redesign to provide alternate means of cooling the 18-story 390-room Indigo Boutique Hotel. The original design had a central plant with chillers, chiller room ventilation, and DDC Controls. The guest rooms had a 4-pipe chilled/hot water, vertical fan coils located at the perimeter wall of the room. The Final design that had savings to the ownership group approximately 5% less than the total value of the original proposal, utilized ductless VRF/VRF fan coils in the hotel rooms, concealed VRF/VRF heat pump ceiling of the public spaces and condensing units located on the high roof. When the construction schedule was impacted due to unforeseen conditions, ACCO start-up and air balance technicians worked two shifts, 10 hrs/day, to achieve the original TCO date. The commissioning schedule was reduced from a 10 to 8 weeks start-up completion.

Metropolis Residence: The design-build system for the 38-story condominium building consisted of a cooling and heating system located on the roof of the building. The system includes a closed-loop circuit fluid cooler, hot water boilers, variable speed condenser water, and pump and programmable controls. Due to construction restraints, the commissioning of the condo tower was reduced from 16 to 10 weeks. ACCO worked two shifts, six days/wk, 10 hrs/day.
