Pei’s cliff-temple for science—architecture that looks like it was carved out of weather data and red rock.
Research institute building operated by the National Center for Atmospheric Research.
Featured in I. M. Pei's definitive monograph, I.M. Pei: Complete Works.
Visitor Guide
Bring water and a layer: the mesa wind bites. Walk the perimeter paths—Pei’s massing is best read in profile against the Flatirons.
From the trail approach below the complex, late afternoon for warm light on the concrete and rock.
Visitor access varies (often includes a lobby/visitor areas and trails); check current NCAR visitor guidance before going.
This is Pei in topographic mode: the ‘geometry’ is about anchoring a modernist object into a landscape without faux-organic gestures.
60–120 minutes
Design & Structure
Massing and circulation tuned to site lines and climate; modular planning supports research program flexibility.
Concrete with earth-toned aggregate—material choice is camouflage and permanence.
Terraced volumes manage wind exposure and thermal behavior; structure supports deep overhangs and robust lab spans.
