2600 Bishop Ranch

Central Plant Upgrade

Nestled in the beautiful San Ramon valley and surrounded by premier dining, shopping, and hotels, Bishop Ranch is a cutting-edge business park owned and operated by Sunset Development, a leading suburban developer in the San Francisco Bay Area. Founded in 1951 and in its third generation of family ownership, Sunset Development maintains high standards for excellence as well as sustainability.

Opened in 1979, Bishop Ranch is one of the company’s premier properties and consists of about a dozen buildings with over 10 million square feet of leasable space. The park’s over 500 tenants include not only larger corporate entities (among them AT&T, Toyota, IBM, and Wells Fargo), but also many small businesses and non-profits in industries from government, insurance, and marketing to manufacturing, engineering, and retail.

In cooperation with the city of San Ramon, Sunset Development plans to transform the bustling business park into a downtown community hub. As part of these plans for enhancement and expansion, Sunset needed a partner to bring its 2600 Bishop Ranch building up to the company’s high standards for sustainability and efficiency. Salas O’Brien’s reputation for excellence and long history in the Bay Area made them a perfect choice to design the mechanical and electrical efficiency upgrades.

This project involved a complete refresh of the mechanical system serving the two-million-foot property. Our team completed in-depth mechanical and electrical review and design services that outlined the removal and replacement of the outdated lake based condenser water system and the installation of three new 1,000 ton chillers and supporting infrastructure. This complex design allowed Sunset Development to reach their ambitious sustainability goals and will support their plans to expand the business park and surrounding area.
