Company: LG Electronics USA Air Conditioning Technologies
Customer: Columbia Square, Los Angeles
Installation: LG Multi V VRF System
Completion: Quarter 4 of 2016
Objective: As part of the large-scale, 685,000-square-foot project, the Kilroy Realty team, located in Los Angeles, desired to not only modernize the look and functionality of the complex but also improve its sustainability and obtain Leadership in Energy and Environmental Design (LEED) certification. This required a new, highly efficient HVAC system with design flexibility to accommodate the shell and core fit-out so that as tenants leased space, they could be incrementally built out and configured to meet their various needs. In addition to superior efficiency, Kilroy Realty wanted a solution that had an advantageous total cost of ownership.
Work Completed: The modularity of the LG Variable Refrigerant Flow (VRF) solution provided the needed flexibility for a two-phased, core and shell approach to installation. In the first phase, the outdoor condensing units were set on the roof and piped down to the floor. In the second phase, the heat recovery boxes were installed, and the tenants selected their indoor units. High static ducted units were used in the commercial spaces. In the residential tower, air handlers with hallway access were installed, so maintenance could be performed without disturbing the residents. The combined modularity and efficiency gave Columbia Square the cost-effective solution they desired. With the ability to operate the system incrementally, Kilroy Realty was not paying to condition unoccupied spaces. Additionally, they could use the heavy recovery technology of LG’s VRF system to balance the demands across the spaces, achieving even greater operational efficiency and further reducing operating costs. The renovation was completed without diminishing the iconic structure, and, in 2017, Columbia Square received the Conservancy Preservation Award as well as LEED gold certification.
