Grosvenor Americas’ 251 Post Street Building In San Francisco Achieves Leed® Gold Certification

Grosvenor Americas’ six-story historic mixed-use building at 251 Post Street in the heart of San Francisco’s Union Square shopping district, home to fashionable retailers Ilori and Facconable, has achieved LEED Gold certification from the US Green Building Council. Very few modifications were needed to achieve the rating, along with an Energy Star score of 75, placing 251 Post Street in the top 25 percent of US buildings in terms of energy efficiency.

“We decided to pursue LEED Gold certification for this building in late 2011, as part of Grosvenor Americas’ ongoing commitment to best practices in support of sustainability,” said Tom Ohlson, Senior Vice President, Grosvenor Americas. Added Barry Giles of BuildingWise, the San Francisco-based LEED certification consultant: “251 Post Street demonstrates that a century-old building can operate very efficiently in San Francisco and elsewhere.”

“The LEED Gold certification of 251 Post Street is part of Grosvenor’s worldwide One Planet Cities initiative, which aims to champion sustainable cities as our part in creating a world that lives within the finite resources of the planet,” noted Ohlson.

Completed in 1908, 251 Post Street was one of the first buildings constructed after the massive 1906 San Francisco earthquake. With 33,636 square feet of space on six floors, the building houses both office and retail tenants. To achieve LEED Gold certification, the ownership implemented a number of cost-effective strategies, including:

  • A comprehensive water efficiency campaign that included replacing sink aerators and toilets to reduce water use by 30 percent.
  • A green cleaning program using certified sustainable products and equipment.
  • Continuing use of more than 200 fluorescent lamps with very low mercury content.
  • Installing a 200 square foot vegetated roof over the mezzanine floor.
  • Donating over 500 pounds of electronic waste to a local computer recycling center.
