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.

Mic Patterson, Vice President of Strategic Development for Enclos, will co-chair the Architects Forum at GlassBuild America on September 11th. The Forum is a partnership between the National Glass Association and Architects Newspaper. The one-day event will bring together designers and industry professionals to the Georgia World Congress Center in Atlanta for an intensive program on the design, fabrication and construction of high-performance architectural and decorative glass. Highlights include a keynote address by architect Neil Denari, one of the leading figures in Los Angeles' dynamic design scene, and an exclusive look at Herzog & de Meuron's Miami Art Museum.
"We are excited about bringing the architecture community to the premier glass, window and door event in North America," says Jim Gandorf, Vice President of Association Services at the National Glass Association. "This is a great opportunity for architects and designers to not only get a day of meaningful education, but to also have the ability to see and experience the latest technology and high performance products that the glass and glazing industry has to offer."
Forum registration also includes admittance to the GlassBuild America trade show floor. Additional information is available here.
As part of Enclos’ 2013 American Institute of Architects Continuing Education System (AIA:CES) series, Jeffrey Vaglio, Associate Director of the Advanced Technology Studio of Enclos, will present to the Building Enclosure Council of Kansas City on Wednesday, July 17th.
Vaglio will present Seeing Double: Double-Skin Facades, an AIA:CES registered course (LU|HSW|SD credit). The session will discuss building envelope performance after the introduction of a second glazed layer, typically resulting in an airflow cavity ranging from 10cm to 2m in depth. The session will discuss the advantages of implementing a double-skin facade (acoustical insulation, winter thermal insulation, night cooling, natural ventilation, thermal comfort, a means of protecting sunshading devices), disadvantages, the global and domestic evolution of double-skin facade technologies, and emerging trends.
Vaglio’s project experience includes a slew of specialty facade structures, ranging from cable nets (*Seattle Family Foundation Headquarters) to point-supported systems (L.A. Live Tower & Residences), skylights (300 New Jersey Avenue) to double-skins (Loyola University Chicago: Information Commons). He is currently a Ph.D. Candidate at the University of Southern California School of Architecture.
BEC-KC promotes the discussion, training and education of all matters concerning building enclosures and its related sciences throughout Kansas City’s building community. The session is open to all professionals with interest in building design, construction, maintenance and property management. Registration for the event is available here.

Field crews install the last curtainwall unit at the atrium’s west elevation.
Field crews installed the last remaining curtainwall unit at the Hyundai Motor America Headquarters on May 21st. The six story, 504,000 square foot high-rise structure includes 135,000 square feet of custom curtainwall installed by Enclos.
The south, east and west elevation curtainwall system includes laminated insulated low-iron glass with enhanced acoustical properties. The north elevation includes insulated low iron glazing. Both acoustical and non-acoustical curtainwall unit modules span 10’ x 15’ and include a ceramic frit pattern.
The project team is delivering Hyundai’s new headquarters campus as part of a fast-track schedule, with all trades participating to accelerate design, engineering, material procurement and construction. Curtainwall systems were installed in a mere five weeks. Enclos’ field team is currently installing 30,000 square feet of soffit panels, 27,000 square feet of channel glazing, and 9,000 square feet of point-fixed glass fin walls.
The $150 million Fountain Valley, California home to multinational automaker Hyundai Motor Company will seek LEED Gold certification, and is scheduled for completion in late 2013.
