Lumen West Los Angeles Repositioning
Tetra Tech’s High Performance Buildings Group is providing mechanical, electrical, and plumbing engineering services to modernize the 1980s Trident Center, a Class A office complex consisting of two 10-story office towers in the Sawtelle neighborhood of West Los Angeles.
Sitting at the confluence of the 10 and 405 Freeways in West Los Angeles, the Lumen Building is being renovated to enhance building performance and occupant wellness, with a focus on indoor air quality. Tetra Tech is teaming with the project architect, Gensler, to create a holistic building system design that enhances overall function. Upgrades are being made to air, water, light, and energy systems, which will result in improved thermal comfort, natural daylighting, and energy savings.
The outside air handling system will incorporate advanced filtration methods, indoor air quality sensors, and demand control ventilation to provide the highest indoor air quality possible. The improvements are designed to control humidity so that future tenants can install radiant cooling systems. To maximize the window-to-wall ratio, the base building mechanical and lighting systems have been improved to boost energy efficiency through the use of high-efficiency chillers, air handling units, and daylighting controls.
Tetra Tech’s electrical design supports the inclusion of more electrical vehicle charging stations than required by California’s strict Title 24 Energy Code. It also allows for significant tenant allowances, which are often required by high-end tech tenants.
In addition, the plumbing has been redesigned to decrease water usage by 11,400 gallons through the installation of new plumbing fixtures (low-flow faucets, toilets, and urinals).
A total of 115,000 square feet of space will be added to the campus, including a restaurant, retail spaces, a fitness center, and several terrace decks. Construction is expected to be completed by 2022.
