Doors in the CU-Boulder Tuscan Vernacular style are usually in pairs and inset in the façade. Doors are often in a heroic scale to signify the importance of the program within and for clarity of location on the façade. Some conform to arched openings, but most are squared leaving a transom to pick up the curvature of openings. Black is the preferred color in either wood or steel. Doors are panelized in various combinations. Hardware is usually bronze, not stainless steel or aluminum.
Original entrance doors have elaborate wood construction of panels and appliqués. Later years have seen steel substitutes. Generally door heights are modest in height to accommodate ease of opening, standard hardware, and reasonable maintenance. Extra height of the opening is gained by transoms of various configurations and side panels. The volume of people entering and exiting determines the pairing of doors, and the amount of glazing needed. Revolving doors at major buildings are sometimes used to combat high west winds.
