Dennis Maes Pueblo Judicial Building has a thin, linear building form; it's a slightly bent bar punctuated in the middle by a rotunda. The 182,350-square-foot building is oriented on a north-and-south axis so direct east-and-west daylight can permeate the interior.

The glass rotunda refers to the form of a kiva, a ceremonial space found in Pueblo Indian villages. The idea of an outer enclosure and inner sanctum is communicated with a wood-framed structure within the glass cylinder rotunda. The wood-framed aedicule has a basket-like structure that filters natural light entering the space from an oculus in the roof above it. The rotunda was constructed around the wood structure. Measurements were verified by making mock-up pieces of the sill.

The blue glass curtainwall refers to the monochromatic, geometric patterns of Anasazi pottery and creates a slightly dematerializing effect that emphasizes the vertical line of the structure and diminishes the scale. Kawneer Co. Inc.'s 1600 Wall System1 Curtain Wall and 1600 Wall System2 Curtain Wall with custom extrusions were specified for exterior glass façade locations including the main entrance.

The 56,000 square feet of curtainwall and 11,000 square feet of storefront framing were finished to match the Fawn Metallic paint coating used on a portion of the Reynobond aluminum composite material (ACM) panels from Alcoa Architectural Products. Chris Ernst, spokesperson for El Paso Glass Co. Inc. and Ryan Glass Inc., the glazing contractors for the project, says a custom extrusion with custom gaskets was required to meet the live load downward deflection at each floor line.

Engineered Wall Systems Inc. (EWS) fabricated and installed 45,200 square feet of 4-mm Reynobond ACM with a fire-resistant core in Classic Bronze and custom Fawn Metallic, Colorweld 500 paint coatings, in EWS Series 400 rear-ventilated, rout-and-return, dry-joint rainscreen. The Reynobond panels were designed to create an aesthetic massing element in contrast to the other materials. The building's color palette was drawn from the local landscape and expressed through the blue glass of the curtainwall and the earth tones of the Reynobond ACM and precast concrete materials.

A segmented, radial screenwall was clad with EWS 400 series panels and runs almost the entire length of the building at the roof level. The screenwall was designed as a visual tie-in to the six-story end of the structure. The entry wall and vestibule are clad in EWS 400 series panels and accented with a canopy of opaque glass panels.

Kawneer supplied its Trifab VersaGlaze 451T Storefront Framing System with an inside-glazed, center-set system and 1/2-inch laminated glass units for the building interior. Additionally, Kawneer's 350 Heavy Wall Entrances were utilized.

The $58 million, LEED Silver-certified project was completed in August 2014. It received an Award of Merit (un-built) from the American Institute of Architects (AIA) Colorado South and an Award of Honor (un-built) from AIA Orlando.
