On 4/18, from 6:30 am to 6:30 pm, Air Handling Unit 4 will be shut down to facilitate the installation of a new air filtration system. During the outage, the airflow on the 6th and 7th floors will be reduced to 50%. The floors will maintain heating and cooling capabilities. The facilities technician will be on site to monitor the building temperatures, pressures, and humidity controls. Thank you for your patience during this time.
