100 Montgomery Street

An ASHRAE LII Energy Audit was conducted at the 100 Montgomery Street building which is a 25‐story office building originally constructed in 1955 as offices for the Equitable Insurance Company. For a 65+ year old office building, the 100 Montgomery Street building is a great example of how a well-maintained building should look and be operated. The building was originally designed by Wilbur D. Peugh and developed by Equitable Life Insurance as their headquarters in 1955. Redesigned by Robert A.M. Stern Architects and restored to its former glory, the building features an ultra-modern crystallized glass exterior, complemented by the refurbished Art Deco metal panels and window mullions. Located at the corner of Montgomery and Sutter Streets in San Francisco’s Financial District, the building has approximately 470,000 gross square feet of rentable space which is comprised mostly of professional, legal, and financial services. The construction of the building is steel frame with concrete floor decks and curtain wall cladding that include aluminum frame single pane windows that are operable hopper windows. There is one basement level and a mezzanine between a portion of the first and second floors with no on‐site parking.
