Salesforce Tower – LEED CS Platinum


An iconic addition to the San Francisco skyline, the 1,070 ft. tall Salesforce Tower (previously called Transbay Tower) will be the tallest building in San Francisco and among the top 10 tallest buildings in the U.S. (source). The Tower will be located adjacent to the San Francisco Transbay Transit Center, which will connect eight Bay Area counties and the State of California through 11 transit systems, including the future planned high speed rail from San Francisco to Los Angeles. Bringing new life, transportation and commerce to San Francisco’s South of Market area, the Salesforce Tower and Transit Center projects are redefining the region with sustainability-focused neighborhood development.

The Salesforce Tower is being developed by Boston Properties and Hines. EBS is providing LEED for Core & Shell (CS) consulting, energy analysis and life cycle cost analysis services, and the project is one of the first SF buildings to be pre-certified LEED Platinum. Meeting and in some cases exceeding the levels of sustainability set forth by the new, more stringent building codes, the Salesforce Tower provides an outstanding example of sustainable design, construction and financial feasibility. Construction on the Salesforce Tower began in 2013 and is scheduled for completion in late 2016.

Sustainability Goals and Features:

  • Significantly improved indoor environmental quality with the use of full outside air economizer ventilation systems and stringent building materials analysis and specifications
  • Floor-by-floor air intake via high efficiency air-handlers allows for significant natural ventilation
  • Under-floor air distribution (UFAD) will greatly reduce HVAC and fan horsepower energy usage, as well as improve occupant comfort and zone controllability
  • Adjacent to the tower is a 5.4-acre public park, which will include a walking trail, vegetation gardens, lily ponds, and outdoor amphitheater
  • Integrated metal sunshades maximize light and views while reducing solar heat gain
  • High performance, low- emissivity glass will help reduce cooling load as well as enhance energy and light transmission performance
  • Floor-to-ceiling windows afford natural daylight and spectacular views
  • Comprehensive water recycling systems in the tower and transit center will help to reduce water consumption 30% below code inside the building, and greater than 50% in outdoor landscaping
