Living Building certified by the Living Building Challenge 2.0 (LBC), the Bullitt Center is a high-performance, net-zero energy and net-zero water urban office building in Seattle. In order to attain the certification, the building had to provide fresh air and daylight via operable windows to every occupant. The building also had to meet indoor air quality standards measured post-occupancy, in addition to the other LBC requirements.
The goal was to maximize occupant comfort while maintaining net zero energy levels. To achieve this, WindowMaster's MotorLink® technology was used with mixed-mode ventilation and night purging. MotorLink® interfaces with the building's management system to open and close the windows automatically, while monitoring indoor air quality and temperature, and activating a radiant cooling and heating system when needed. MotorLink® also permits manual override of the windows so the occupants can open and close them to suit their needs.
The high-performance facade helps the building exceed expectations and achieve an EUI of 11 when fully occupied, though it is designed to achieve an EUI of 15.
