Dynamic facade for natural ventilation

WindowMaster provided more than 1,000 MotorLink® actuators that integrate the façade to the LONworks Buildings Management System. This enables full control of each motorized window. The patented MotorLink® allows the actuators to operate intelligently with the BMS so that natural ventilation is controlled automatically in coordination with the building’s heating and cooling systems.

Atrium design with natural ventilation

The façade of the atrium is an all-glass, multi-story structure attached to a steel frame. The atrium contains automatically operable windows which are fully controlled by the BMS. The smoke exhaust fans in the atrium can be used at low speed in combination with the natural ventilation to enhance cross ventilation.

When natural ventilation is appropriate for the climate

Outdoor temperatures in Baltimore are appropriate for natural ventilation about 40% (approximately 5 months) of the year. Therefore, a mixed mode approach to the interior climate is taken, with mechanical ventilation, heating, and cooling during the extreme seasons and natural ventilation during spring and fall. According to Behnisch Architekten, the Law Center achieves a 43% energy cost savings over a baseline building.
