Philadelphia Police Headquarters

High Profile Projects / In Design/Construction / Municipal

Location: 400 N. Broad St


General Overview: The historic 24-story tower on North Broad Street, formerly known at “The Inquirer Building”, will be the location of the new Philadelphia Police Headquarters. Chosen for its central location, ample parking, and spacious interior, the new headquarters will merge several law enforcement functions currently spread out in different locations across the city. These include the city’s morgue, toxicology labs, emergency dispatch center, the Sixth and Ninth Police District Stations, and the commissioner’s office, utilizing the 466,000 square feet of the former newspaper facility.


Several notable elements of the original building will be preserved and reused, such as the globe chandelier and marble floors, walls, and staircases. The design team is working closely with historic preservation groups to restore the exterior of the building to its former glory. The building will have LEED Silver accreditation. 


Special MEP/FP Features: AEI designed high-reliability mechanical and electrical systems to ensure continuous operations regardless of outside utility support. With the city’s incorporation of the E-911 police and fire call centers, the system supports electrical and mechanical systems needed for a high level of redundancy to maintain uninterrupted operations.


The design utilizes a low-temperature supply air system that incorporates fan powered boxes, each equipped with a thermostat and CO2 sensors for accurate ventilation air control of every space. There is an enhanced ventilation mode that allows for increased ventilation in zones that register high occupancy. This innovative approach enhances indoor air quality for the occupants while being energy conscious in the delivery. 


The morgue/autopsy and toxicology labs have a dedicated 100% outside air system that includes humidification and dehumidification. Within the morgue is a BSL3 level iso autopsy suite that incorporates laboratory standard air containment and HEPA filtration. All of these systems incorporate N+1 redundancy on the fans. The laboratory and morgue/autopsy spaces necessitated a dedicated lab waste drainage system including biokill and chemical neutralization tanks.


The detention area a dedicated air system to meet the unique requirements. Code requires high exhaust levels in the detention cells which led to incorporation of energy recovery wheel in the air conditioning unit. AEI created an energy efficient system to address the high code exhaust needs by utilizing return air from support spaces to make up part of the air requirement for the detention cells. 


AEI Services Provided: Mechanical, electrical, plumbing, and fire protection services and construction support.
