Colorado State University – Morgan Library

Horizon Glass delivered the curtain wall and glazing scope for the “”Study Cube”” addition to CSU’s William E. Morgan Library, a two-story western expansion creating new commons and group study space for the Fort Collins campus. Designed by Studiotrope Design Collective and built by Pinkard Construction, the Cube addition was completed to LEED Silver standards and gives the library a striking, transparent western face overlooking the campus.

Horizon’s scope encompassed the EFCO 5600 curtain wall with Series 325 vent windows and All-Lite sunshade adapters, featuring one full elevation of SageGlass electrochromic glazing on the building’s western exposure. The dynamic glass wall—zoned so the upper and lower floors tint independently in response to an exterior light sensor or manual control for events—automatically darkens or clears to manage the harsh western afternoon sun, controlling glare and solar heat gain while preserving daylight and views for the study spaces within. Completed in 2012, the Cube remains a signature daylighting feature of the renovated library.
