The new home of the John and Frances Angelos Law Center at 192,000 square feet, unites classrooms, faculty offices, administrative space, and the law library under a single roof for the first time in the history of the school. The building, located at the prominent intersection of Mount Royal Avenue and Charles Street, functionally and symbolically defines the Law School as an academic and social nexus, offering state-of-the-art teaching and learning facilities.
The WindowMaster solution
WindowMaster has provided more than 1,000 MotorLink® actuators integrating the intelligent facades with the LONworks Buildings Management System. This enables full control of each motorized window. The windows will then be automatically closed when the airconditioning is on, but are made available for the users to freely open and close by the manual override switches when the airconditioning is off.
Operable windows are provided in regularly occupied spaces, allowing users to have direct control of their environment. Occupants have local control of operable windows in all office, teaching and library spaces, and are notified of favorable outdoor conditions by means of a green indicator light that communicates appropriate times to open a window. Atrium operable windows are fully controlled by the building automation system based on the quality of outdoor conditions. Atrium smoke exhaust fans are activated at low speed in natural ventilation mode to guarantee good cross ventilation through all spaces, and acoustically protected and fire-protected transfer openings are provided from perimeter spaces to the atrium.
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. The law center does have a conventional HVAC system, but it is less than half the size of one that would be required for a normal building of its size.
