Performative Envelope Lab

Performative Envelope Lab

  • One of the projects highlighted in the Performative Envelope Lab research is the Leamouth Peninsula Building N in London. Tight, urban site conditions limit the amount of greenspace on the site, so the architects looked to include vegetation in vertical garden façades overlayed on reinforced-concrete walls on each of the four faces of the building.

“It’s a systemic approach—they presented different strategies for different envelope and shading propositions,” juror William Massie says, explaining why Performative Envelope Lab research by Skidmore, Owings & Merrill (SOM) stood out from the pack. SOM based its research on nine buildings, designed by different teams within the firm, each illustrative of forward-thinking building-envelope design. Projects covered techniques from frit patterns to parametric design to environmental shading.

The SOM team looked at curtainwalls post-construction and drew conclusions from real conditions, not solely from modeled performance. The jury lauded a large firm’s commitment to self-evaluation and a continual manipulation of the exterior envelope in order to respond to the demands of each site. The lab’s criteria went beyond factors of energy consumption or sustainability, and included issues of cultural context, identity, and security. One example, the Zhengzhou Greenland building in Zhengzhou, China, used a light-gauge-metal shading system to protect the all-glass tower from heat gain. The form takes its cues from the traditional stepped pagoda. In another example, the Leamouth Peninsula Building N in London, SOM responded to the need for greenspace on a tight site by creating a four-sided vertical garden. Its strategically detailed curtainwall allows for rampant plant growth with minimal maintenance.

But more than the individual projects themselves, it was a dedication to process that struck the jurors. They saw a practice devoted to skin analysis and to transforming conventional ideas toward façades. “We chose it [the Performative Envelope Lab] because it actually analyzed building façades in a meaningful way,” juror Julie Eizenberg says. “It’s research and development in the manner of standing back and looking at what was done and what are potentials, rather than research and development relative to invention.”
