Adaptive Reuse

Colorado's “Prism Plane” project by Tres Birds

The highlight of Boulder's low carbon footprint building is the 52 ft wall, a uniquely designed configuration that merges art, science, and the sun to create an architectural kaleidoscope

by Georgina Johnston 13 April 2021

The reclamation project took a nondescript brick 80s office park building and transformed the corporate headquarters into an inspiring place to work to maximise both human and environmental health. Custom-fabricated glass panels reflect and radiate spectrums of colour onto the walls and ground. The reflections vary as the sun moves across the sky and the seasons change, providing an ongoing radiant colour show. 

The reclamation project took a dark, cloistered building with narrow and convoluted circulation, and turned it into a daylit, energy efficient, flexible, and healthy office space. Tres Birds selectively removed exterior and interior walls to create transparency, views, and a clear sense of circulation through the building. 

Skylights, glass walls, and a new atrium opening allow the sun to penetrate deeply through the building. In many locations the user receives sunlight from three or four directions simultaneously, creating a happier, healthier workspace for the building’s occupants. Large, clear windows highlight the impressive mountain views in Boulder, all but hidden in the previous configuration of the building. 

The folding glass curtain wall inserted into the existing brick façade, dubbed “Prism Plane,” is made from clear and dichroic coloured glass. The panes reflect and refract colour through and around the building and change with the time of day as well as the angle of the viewer. Each panel is placed at a unique angle to increase the kaleidoscopic effects of the glass. As a 38 ft steel hydraulic door pivots upwards allowing the outdoors in, more reflections and refractions interact with the ground and the curtain wall above. Every day of the year provides a new radiant colour show inside and out. 

The renovations included improvements in energy use as well. A 60kW photovoltaic array was installed on the roof, windows were upgraded to double pane low-e IGUs, and low flow Kohler plumbing fixtures were installed. The use of LED lighting with full dimming control zones allows the use of artificial lighting only where necessary at any point during the day. 

Whenever possible, Tres Birds converts fossil-fuel-heavy parking lots into green gardens for the dual benefits of oxygen production and reclaiming natural space. At Prism Plane, the former parking lot and loading area was transformed into an outdoor space with seating and a garden. The outdoor workspace allows employees to take advantage of Boulder's gentle weather and work in an inspiring environment.
