In late 2012, the Club purchased the 100+ year old building on San Francisco’s waterfront with plans for its complete renovation. The new building—including its transparent glass front along The Embarcadero—will be the Club’s first permanent headquarters, a physical symbol of the visions and ideals of the Club’s founders in 1903, when they set out to create an Agora or “open place of assembly” for San Francisco.

Trickle vents are incorporated into the proposed Embarcadero façade, passively heating and cooling the building interior with ‘Bay Air’.

Energy Efficiency Goals for the Building

Diagram by ARUP

The proposed Embarcadero façade has 51 operable windows and high performance glazing, contributing 33 points to three LEED credit categories and 2/3 of the overall LEED scorecard:

• Indoor Environmental Quality

• Energy and Atmosphere

• Regional Priority Credits

Low Carbon Footprint for the Building

Structural Design Goals

• Integration with architectural space plan

• Avoid modification to existing foundations

• Reuse portions of existing structure

• Seismic safety

• Sustainability

Structural Design

Remove existing concrete property-line walls above level 2 and replace with lightweight metal stud wall

2nd Floor supported on interior columns

3rd Floor and roof span to exterior walls

Reuse majority of street level framing

Strategic loading so as to reuse existing foundations

~70% probability of a M6.7+ earthquake in the Bay Area in the next 30 years

-U.S. Geological Survey

Bay Area Seismic Hazard

Traditional cantilever wall combined with unbondedpost-tensioning

Combines elastic spring and yielding damper

Hybrid Advantages:• Self-centering response• Reduced rebar congestion• Stronger and more

compact• Tough and damage

resistant

Seismic Design: Post-tensioned Concrete Walls

Seismic Design: Post-tensioned Concrete Walls

• Cement replacement

• Simple and effective

• Significant reduction in CO2

• Trade-offs with local material use

• Minimal or no cost premium

• LEED does not fully capture benefit

CO2 Emissions from Concrete

Slag is the glass-like dross resulting from the smelting of ores like iron.

It is a recyclable by-product of blast furnace steel production.
