User Note:
While great efforts have been taken to provide accurate and complete information on the pages of CPEP, please be aware that the information contained herewith is considered a work‐in‐progress for this thesis project. Modifications and changes related to the original building designs and construction methodologies for this senior thesis project are solely the interpretation of Christopher Ankeny. Changes and discrepancies in no way imply that the original design contained errors or was flawed. Differing assumptions, code references, requirements, and methodologies have been incorporated into this thesis project; therefore, investigation results may vary from the original design.

The window-wall system will be constructed of 7.5" aluminum mullions with 1" low-e glazing units and opaque spandrel glass units.  Portions of the glazing on the atrium will be fitted with a ceramic frit screen pattern.

The roof will be constructed of a modified bitumen system over corrugated structural roof deck.  The steel structure will be sloped to roof drains located along the center bay of each wing.  There will be tapered insulation crickets to direct rain water toward drains between collection areas.

The roof assembly will consist of the following:

• Structural steel deck
• 4" rigid insulation pinned to deck
• 1" recover board adhered to insulation
• Modified base sheet adhered to recover board
• Modified roof membrane and cap sheet adhered to base sheet

The power distribution system for the Villanova University: School of Law is a simple radial system.  The electric service is connected to the university’s 13.2kV underground primary distribution system with a 15kV primary loop switch.  The service is provided by a 2000kVA, 13.2kV primary voltage to 480Y/277V secondary voltage, 3 phase, 4 wire transformer located outside the building.  A 3000A, 480Y/277V, 3 phase, 4 wire switchboard is located in the sub-basement and will distribute power to the building. The switchboard provides power to elevators, the chiller plant, AHUs, and the lighting and receptacle panels.  The receptacle panels are supplied through a 480V to 208V transformer.
 

In an ongoing effort to lessen the impact construction has on the environment, the law school utilizes mostly fluorescent lighting.  In the larger spaces (i.e. classrooms, lecture spaces, courtrooms and the stacks in the library) fluorescent pendant lighting is used to provide the uniform ambient lighting.  In smaller spaces such as faculty offices and egress corridors, recessed compact fluorescent luminaires are used.  In areas of interest, some incandescent lighting is used throughout the building.  In the hallways, there are coves above each door which are illuminated with tubular fluorescent luminaires as a way to draw your eye to the entrance of the space. 

In almost every space that is accessed on regularly, at least one occupancy sensor is used as a way to ensure that energy is not used during unnecessary times.  Some spaces have time switches at the entrance that serve the same purpose.  These spaces are mostly spaces that are not used for extended periods of times.  Photocells have been utilized in areas with a large amount of glazing.  This is yet another way to ensure that all possible energy savings are being used.

In addition to these localized controls, the building has three lighting control panels that control the times of operation of the lighting throughout the building.  Spaces such as offices are turned on at 8 am and shut off at 6 pm, unless of course the occupancy sensor prevents it.  The areas that will be used by students for longer periods of time will be switched on at 7 am and shut off at 10 pm.  Again this will not affect a space if it is being used because the occupancy sensors will relay that information back to the LCP. 
 

The Villanova University: School of Law utilizes one 300-ton water-cooled, centrifugal chiller and one 300-ton two-stage direct fired absorption chiller which are located in the lower level main mechanical room.  The chilled water system is a primary-secondary system.  One primary constant volume, base-mounted, end suction chilled water pump is provided for each chiller.  Two secondary, variable volume, base-mounted, end-suction chilled water pumps are provided and each is sized for 100% flow. 

Two induced-draft, crossflow, single-cell cooling towers are located on the room.  Each tower serves an individual chiller.  One serves the absorption chiller and is sized at 4.0 gpm/ton.  The other tower seves the centrifugal chiller and is sized at 2.5 gpm/ton. 
 

Heat is provided using Villanova University’s central steam plant.  Steam is provided year round to the facility.  A 4-inch, 125 psig steam line enters the main mechanical room on the lower level.  The steam line is sized to provide approximately 10,350 MBH or 8,990 lb/hr. 
 

The fire alarm system is a solid state, multiplex, addressable fire alarm system that consists of graphic annunciation panels at the entrance lobby.  Manual pull stations, audio/visual devices, flow switches, tamper switches and smoke and heat detectors are located throughout the building.

The fire alarm system is connected between the building security system and the campus central security console.  The fire alarm system can be monitored through any computer and a printer can output all fire alarm activity.  The smoke and heat detectors for the elevator system are interfaced with the elevator controllers for elevator recall and shut down requirements.
 

A duct bank for telecommunication service to the law school is provided from Villanova University’s campus telecommunication network.  A main telecom demarcation room is located in the basement.  Two telecom rooms are located on each additional floor.  A complete telecom raceway system consisting of back boxes, conduits, and ladder trays are run throughout the building on each floor.
All voice and data cables are provided by others as part of a separate contract.  Card access system equipment is also provided as part of a separate contract. 
Finally, a complete security raceway system is provided throughout the building where needed.
