Explain the project and its unique use of masonry materials and techniques:
Anticipating a resilient future for libraries, Weber County Libraries replaced a traditional branch library with a new Headquarters Library located in the rapidly expanding population center of Roy, Utah. Thus, the new library provides considerable emphasis on community related elements, especially those that serve a broad audience. The building includes a black box theatre, a public gallery, flexible multipurpose rooms with catering kitchen, a digitally sophisticated conference room and cyber café. The program includes a secured public reading garden that show-cases indigenous plant materials, xeriscaping and a performance amphitheater with a focus on a community gathering forum. The central natural lighted space suggests a historic reading room that opens to the south facing porch, amphitheater and garden beyond in a seamless spatial sequence.
The building was designed to Gold LEED standards with the idea it is a showcase for sustainable design. Some of the sustainable design strategies include copious daylighting throughout, passive solar design at the south facing windows, use of regional materials high in recycled content, flexible open spaces and building systems designed to accommodate change, and energy efficient lighting and mechanical systems.
The building’s exterior envelope is comprised of brick masonry, concrete masonry, concrete, steel, aluminum sheet metal paneling and glazed aluminum curtain wall systems. In some instances, the use of the exterior finish materials continue through to the building’s interior to reinforce the definition of the building’s volumes. This is demonstrated at the surrounding masonry walls of the black box theatre, meeting rooms, board rooms and elevator hoistways.
The building is predominantly finished using an emperor shape dark iron spot smooth face brick laid in a running bond pattern, with natural mortar color corresponding to the building’s exposed concrete finishes. The mortar joints are raked 3/8-inch from the face of the brick at the bed joints, and flush struck at the head joints to emphasize the horizontal coursing of the masonry. The iridescent quality of the dark iron spot brick interacts with the site’s ever changing atmospheric lighting conditions, creating an interplay of reflections throughout the masonry surfaces, effectively reducing the overall appearance of the building’s scale.
The dark iron spot brick is carefully used at the building’s programmatic areas where the need for daylighting is minimal, such as the black box theatre and the administration support spaces. Window openings that occur in the masonry envelope are provided as deep recessed openings to the building’s interior. Above and below the windows, the brick veneer is held back to align with the window jambs for the height of the entire volume, exposing the supporting back-up concrete masonry block structure behind the veneer. The exposed concrete masonry structure is finished in a white honed-faced concrete masonry surface to contrast the dark iron spot brick, and is coursed to align with the brick coursing at both the bed and head joints, further emphasizing the integration of the masonry assemblies. At other programmatic areas of the building where a greater demand for daylighting is required, such as the grand reading room and children’s areas, the use of masonry is lessened to the point that only the skeletal layers of structural steel and glazed curtain wall remain as the residual elements of the building envelope.
