150 Spear Street is an 18-story high rise in the South of Market Area (SOMA) of San Francisco, with more than 286,500 square feet of floor area. Principal Real Estate Investors owns the property and it is managed by Colliers International. The management team has worked extensively to increase efficiencies, in order to reduce utility costs and earn Leadership in Energy & Environmental Design (LEED) Platinum certification. The property’s 1-100 ENERGY STAR® score has increased from 86 to 94 points in the last two years alone, which is a testament to the building team’s commitment to saving energy and resources.

Due to the commitment shown by Principal Real Estate Investors, a large list of energy efficient measures were completed by the property’s team, including the following: installation of a new cooling tower with a high efficiency fan on a variable frequency drive (VFD), installation of light-emitting diode (LED) lighting in the stairwells, and installation of proximity controls in the loading dock and garage areas. The team also enhanced programming on the building control system to more effectively provide cooling to the floors. In addition, toilets were replaced, reducing water consumption by over 28 percent. These initiatives, along with others completed in 2013 and 2014, have reduced energy usage by 13.6 percent.

150 Spear Street actively participates in Principal Real Estate Investors’ Pillars of Responsible Property Investing (PRPI) initiative. Based on the United Nations Principals of Responsible Investment, the PRPI initiative emphasizes operational excellence, and acts as an expanded fiduciary framework to better serve the needs of clients, investors, tenants, and the community.
