Vertical fins and lightshelves control daylighting. Design Theme The goal was to design a sustainable headquarters in Little Rock, Ark., that would exemplify Heifer’s mission, express their sustainable attributes for educational purposes, and allow all employees to work as equals. Completed in 2006, the building’s gentle curve emanates from the overall four-phase master plan, conceived as a series of concentric rings expanding outward from a central commons that represents the impact point of a gift. The ringed site physically and metaphorically expresses the ripple effect of passing on the gift, which is also reﬂected in the Headquarters’ layered planning. Crafted to maximize sunlight and rainwater while conserving energy and avoiding pollutants, the headquarters sees a 52.6% energy saving over the ANSI/ASHRAE/IESNA Standard 90.1-2001, Energy Standard for Buildings Except Low-Rise Residential Buildings budget building. The 22-acre reclaimed site, among the largest brownﬁeld recoveries in Arkansas, was once an industrial railroad switching yard whose tracks bisected the property. Existing masonry structures were crushed into a gravel material for use on the site and bricks were reclaimed for site paving. Overall, 97% of the materials were recycled, and the savings in reclaimed usable material paid for the entire site demolition. A narrow, 62 ft wide ﬂoorplate and north-south orientation enable daylight to penetrate to the center of ﬂoors, giving every employee daylight and a view. The majority of employees are given the best northern views to the Arkansas River, Riverfront Park and Clinton Presidential Library.
