Executive Summary The Milton S. Hershey Medical Center Academic Support Building is located on The Pennsylvania State University's campus in Hershey, PA. The building is owned by The Pennsylvania State University and was built on university owned land. The five story, 146,316 gross square foot building houses various departments of Penn State College of Medicine and The Milton S. Hershey Medical Center. The building consists of a central core connected to two angled wings. The building wings house the departments' suites with offices on the perimeter and open floor plans in the center. The central core houses a stairwell, elevators, rest rooms, and shared conference spaces. The building materials are mostly pre-cast concrete and glass with a mechanical penthouse enclosed in high quality painted steel. The building's mechanical and electrical systems were designed to facilitate the need for building program versatility. The underfloor air distribution system provides control over personal air supply through the adjustable diffusers as well as the flexibility of adding and removing diffusers based on zone occupancy. The underfloor air plenum also houses relocatable electrical and data floor boxes. These floor boxes include 2 duplex telephone/data jacks and 2 duplex outlets with minimum of 10 ft of wiring slack required to permit flexibility of location. The flexibility of this system allows the building program to change frequently without costly modifications to the existing electrical and HVAC systems in the occupied space.

Hershey Medical Center Academic Support Building is a mixed office use building. It houses departments from both Penn State College of Medicine and Hershey Medical Center. The building wings designed for flexibility of department suites. There is also a staff cafeteria on ground floor. Location and Site Penn State College of Medicine, Hershey, PA The building site is adjacent to non-campus residential properties and Ag/conservation fields. It is also near campus's mega-structure. Architecture The exterior of the building is not extravagant. Materials are dominantly pre-cast concrete and glass. Abundance of landscaping and parking surrounds the building. The building was designed to facilitate flexibility of the building program. Building consists of a central core with two angled wings. The core of the building houses the elevators, stairwell, rest rooms, and shared conference spaces. The wings house suites that will have distinct entrances for each department. A staff eating area is provided for the entire building. The mechanical penthouse is enclosed in high quality painted metal.

Zoning and Historical No special zoning issues. Project Delivery System Construction Project Management approach where the owner (Penn State) has a project manager. The owner hired both the architect and the construction manager. The architect hired the engineering consultants and the construction manager hired the sub contractors.

The building also has 2 emergency dry transformers, a 30KVA serving floors 1-3 and a 15KVA serving floors 4-5 and penthouse. A 120/240V panel serves the food service/storage area. Door security card reader system Video system with room for future cameras and satellite dish for the roof Fire alarm system is an addressable multi-plex system designed to have 100% spare capacity over designed points. It is listed for auxiliary and remote station service in accordance w/ UL 860 - Control units for fire protective signaling service. Fire alarm panel has interface module to main ATC panel, fire alarm annunciation (120V ac normal emergency supply) manual pull stations, fire alarm visual signaling, sprinkler system interface, and tamper switches on control valves. Smoke detectors are located in ducts and occupied areas. Elevator shafts have both heat and smoke detectors while the cars only have heat detectors. The fire alarm panel is also tied into smoke proof enclosure systems. Site Lighting control panel Hand/Off/Auto integrated 365 day, 8-channel time clock photocell. Time clock control and photocell control (auto/bypass) is in series for permitting site lighting. Underfloor junction boxes are mounted on concrete floor feeding flexible/detachable connectors to plug into relocatable floor boxes. The floor box installation includes 2 duplex telephone/data jacks, 2 duplex outlets w/ minimum of 10 ft of wiring slack to permit flexibility of location.
Lighting Outside lighting is 175W metal halide post-top lighting Architectural area lighting is compact fluorescent ballards Flush mounted 75W incandescent well lights for spotlighting General interior lighting is compact fluorescent and F-32 T-8 277Vw/ electronic ballasts, some with dimming. LED 277V type exit signs Some incandescent specialty decorative lighting Mechanical The building's HVAC system is an underfloor air distribution system. Perimeter spaces are served by automatic floor diffusers and interior spaces are served by manual floor diffusers. Each floor has a ceiling plenum return w/ return air dampers leading to the return air shaft and the return air plenum penthouse.
