Architectural Record examines 680 Folsom Street’s renovation this week in “Facade Retrofits: Wrap it Up.”
The 1960s office tower in San Francisco recently underwent a redesign courtesy of Skidmore, Owings & Merrill that includes the removal of its original pre-cast concrete shell, and the installation of new high-performance glass curtainwall systems. Enclos provided comprehensive design/build services for the renovation’s 190,000 square feet of building facade.
The Architectural Record write-up digs deep into the project’s cladding and structural improvements. You can read the article in its entirety here.
The New York Times’ documentary, “A Short History of the Highrise,” was released this week. The four-part, interactive documentary draws from the publication’s photograph archives to tell the world’s 2,500-year history of vertical living.
The documentary is available here.
The New Yorker discusses the style of David Adjaye, the architect of the upcoming National Museum of African American History and Culture in Washington, D.C., in the publication’s “Annals of Architecture” section this week.

Critic Michael Webb states that “A Gold LEED rating is one measure of the Courthouse’s efficiency, but it triumphs in many other ways: as a graceful departure from the lumpish mediocrity of its neighbors, as a guardian of green space at the heart of the city, and by transforming public perceptions of the law in action.”
Enclos provided design/build services for nearly 300,000 square feet of facade. Glass material in combination with minimal supports streams natural daylight throughout the structure's east elevation, showcasing the courthouse’s public half with a metaphorically transparent skin. The west elevation houses private offices and therefore must limit transparency. Here a largely terracotta clad wall system uses glass to systematically distribute natural lighting throughout the tower while maintaining both privacy and security.
One hundred and fifty billion square feet of commercial buildings will need to be renovated over the next 30 years*, and some estimates indicate that as much as 70% of the existing building stock suffers from underperforming facades. The early aluminum framing systems used during the high-rise boom of the mid-20th century were not thermally broken, often allowing for air infiltration and water penetration. IGU technologies were new, with a tendency for seal failure. In recognizing this, the McKingsley Report suggests that a $170 billion investment into the retrofit of existing buildings would cut 23% of total building energy use, yielding a 17% return on investment. In addition to energy savings, improved worker productivity also has enormous potential value.
Enclos’ New Skins, Old Bones: Facade Retrofits for Tall Curtainwall Buildings, an AIA:CES registered course (LU|HSW|SD credit), examines emerging retrofit opportunities by identifying and comparing:
- A historical perspective and recognition of the failures of facade systems used during the high-rise boom of the mid-20th century.
- Why retrofitting tall buildings will be essential in the 21st century.
- A means and methods for the retrofit process, including feasibility (building survey, prelim program definition, financial analysis, financing options), design & engineering, and implementation (procurement, fabrication and assembly, installation, commissioning, post-occupancy monitoring).
- Case study examples.
About the presenter:
Mic Patterson, LEED AP [BD+C], has made a career study of building facades, participating in the design, fabrication and installation of a remarkably diverse body of novel applications. He founded ASI Advanced Structures Inc in 1991, the firm that pioneered the introduction of advanced facade technology in the US marketplace. Enclos, a leading global curtainwall firm, acquired ASI in 2007. Patterson subsequently participated in the establishment of the Advanced Technology Studio of Enclos, a facade think-tank located in downtown Los Angeles, where he works as the Vice President of Strategic Development. Patterson earned a Masters of Building Science degree from the School of Architecture at the University of Southern California, where he is currently a PhD candidate. He has taught, written extensively and lectured widely on diverse aspects of advanced facade technology. He is the author of Structural Glass Facades and Enclosures, published by Wiley in 2011.
