RELEVANCE
v
The building skin combines considerations of performance and appearance like nothing
else in architecture.

Analysis
Utilizing our inhouse software developmentcapabilities, we were able to custom tailora set of procedures to study geometricalcharacteristics of the sloped wall system.
The images to the right are a sampling ofthese analysis. It estimates the warpage forthe structural framing and galvanized backpans as well as the stainless steel claddingpanels. They depict initial geometry andthe subsequent subdivisions to createindividual unit and panel discretization.It is our intent to use these tool to furtheroptimize the final geometry to establish amore robust and economical solution to thepanel system.

• We take the raw float,
• make the IGU,
• collapse the durability from 100s of years to 20-30 years,
• make it not recyclable in the process,
• and call it high-performance glazing!
IS GLASS GREEN?not once we get done with it!

• Preservation through a planned process of continuous renewal (versus heroic restoration).
• Explore durability and the potential for maintenance and partial renovation cycles to extend service life and minimize embodied energy and carbon impacts using LCA techniques.
• Develop concepts for highly durable curtainwall systems and components.
