Structure

The Bullitt Center features a hybrid construction system. The three structural systems are: Concrete: The lower second floor consists of concrete columns and floor slabs. Concrete can support the structure of the upper floors. Timber: The rest of the floor is made of heavy timber, with a structure of columns and beams absorbing the loads from the concrete foundation. Steel: There is very little waste in procuring and polishing steel. Moment frames placed within the trellis provide vertical and lateral support.

Light & Air

The Bullitt Center is a high-performance building that uses state-of-the-shelf technology, such as the Schüco triple-glazed curtain wall and ground-source heat pumps. These components are high-cost, but when integrated into systems of reinforcing elements, they are critical to achieving high levels of performance. Fourteen-foot floor-to-floor ceiling heights and window heads that extend to the ceiling maximize daylight penetration so that electric light is generally not necessary during daylight hours even under commonly overcast skies. To be certified as a Living Building, the Bullitt Center must annually produce as much electricity as it uses.

Enclosure

EXTERIOR SHADES Automated exterior shades filter sunlight and reflect heat OPERABLE WINDOWS Give users more control over temperature via environmentally friendly means. Straight-out windows provide excellent airflow. METAL CLADDING Limited thermal bridging and absorption is achieved by installing a custom tongue and groove lap panel siding under a Schuco mullion. TRIPLE PANE GLASS Improves insulation and regulates internal temperature. AUTOMATED LOWER WINDOWS Programmed windows open and close on a temperature dependent schedule, cooling and heating the building
