Architecture:

The new Temple University Tyler School of Art will move from its current location in Elkins Park to be apart of the main campus.  The building will become the signature of the arts campus at Temple University and is apart of $400 million dollars in campus improvements that Temple University is taking part in to revitalize the main campus.  The new Tyler School of Art will house studios, shops, classrooms, assembly areas, and support services.  Architect Carlos Jimenez, who is known for designing several leading art education buildings throughout the country, will lead the design of the art school.  

The main subdivisions are broken down to administration, auditorium, and art education.  The floors are divided into the first floor being photography, wood, ceramics, sculpture, and glass.  The second floor features printmaking, graphics, and metals.  The top floor is divided into spaces relating to painting.  The departments are based around a two story main lobby and promenade the stretches between the north and south wings of the building.      

Building Envelope:

The building envelope consists of masonry wall, metal siding, and curtain wall.  The masonry wall system uses a face brick with a 2 inch airspace.  The rest of the wall construction consists of 2 layers of Tyvek, 5/8” DensGlas gypsum sheathing, metal studs with R-19 batt insulation, a vapor retarder sheet, and finally painted gypsum drywall.  The metal cladding uses the same wall system as the masonry except Kynar coated galvanized interlocking sheets are substituted for the brick and the airspace. 

One inch insulated clear glass, which is low-e annealed and heat strengthened, is used in the curtain wall located in the main lobby.  The framing for this curtain wall uses interior extruded aluminum support mullions.  There is also a blue tinted glass at various exterior locations.  This glass uses a titanium coating on the outer layer and then clear glass on the inner layer.  

The roof construction differs for the flat and the pitched roof areas.  The flat roof area uses EPDM black sheet roof membrane, ½ inch recover board, 4 inch isocyanurate board, and 5/8 inch fire barrier board made of reinforced gypsum.  This roof construction sits on corrugated steel deck.  The pitched roof has the same construction but it also includes a PVC colored roof membrane with adhered false battens. 

Historical Requirements:

The building is located on a vacant lot so no historical requirements or special zoning need to be taken into consideration.

Structural:

The standard foundations are cast in place continuous spread footings and freestanding column footings.  Foundation uses cantilevered foundation walls.  All of this is done with 4000 psi reinforced concrete.  The basement features cast in place reinforced concrete foundations with brick shelves cast in where grade extends below the first floor line.  The floor system consists of hot rolled steel framing with and cast in place concrete over the corrugated steel deck.  The typical framing grid is 30’x30’ with W18x35 girders and W16x26 beams.   

Mechanical:

The mechanical system consists of (3) roof top units (RTU), (4) basement air handling units (AHU), and (1) 5000 cfm basement makeup air unit (MAU).  Two of the AHUs and one of the RTUs will be 100% outdoor air constant volume reheat systems.  These units predominantly service the studio spaces in the building.  The rest of the units will be variable air volume reheat and the MAU will service only the 1st floor furnace room.  The air handling units range from 35,000 to 62,000 cfm. 

High pressure steam (HPS) is supplied to the Tyler School from the Temple University central heating plant.  The is a new pressure reducing station that reduces the steam to low pressure steam (LPS) at the building.  The LPS is used for preheating coils in the AHUs, heating and ventilating units (HV), and heat exchangers.  The heat exchangers are used for the domestic hot water system, humidifiers, and heating the hot water system for the building heating terminal units like unit heats and reheat coils. 

Chilled water provides the cooling throughout the building.  A new chiller will be installed at the Temple central plant to handle this load.  The chilled water will be circulated to the AHUs by four (4) variable speed single stage end suction pumps. 

The building HVAC system uses fully integrated DDC controls.  

Lighting/Electrical:

The Tyler School will receive dual source primary 13.2 kV service by using two primary main breakers and a primary tie breaker.  The breakers will be electrically interlocked to prevent parallel operation and all the breakers closing at once.  The secondary service will use a double ended unit substation.  This system will also interlock the breakers in the same manner as the primary configuration. 

The substation consists of (2) 600A 15kV HV switch compartments, (2) 2,500 kVA 13.2kV Primary 480Y/277V secondary 3 phase 4-wire dry type transformers, (2) 4,000A circuit breaker main compartments and (1) 4,000A circuit breaker tie compartment, and six distribution feeder breaker compartments.  Eleven electrical rooms will handle the secondary electrical distribution.     

The emergency power will be provided by a 500 kW, 480Y/277 Volt, 3 phase, 4 wire, 60 Hz, diesel driven standby emergency generator. 

The majority of the lighting will be fluorescent.  Specialty lighting is considered interior public gathering spaces, and elevator lobbies.  The exterior lighting will be time controlled featuring multiple lighting contactors for switching 277V and 120V lighting loads on and off.  The exterior areas that are apart of the Tyler School’s lighting plan are exterior entrances and exits as well as public and service pathways.

Plumbing:

 All installation is done in accordance with the Philadelphia Plumbing Code.  Domestic water is provided by an existing public water main service entrance.  Fire water service to the Tyler School will be provided by a separate water service connected to a fire pump.  All piping that is 6-inch or larger is constructed of ductile iron.  All piping 4-inch and smaller is copper.  All the copper piping is Type L hard copper with wrought fittings and solder joints.  The sanitary piping is constructed of cast iron. 

Fire Protection:

The fire protection system will consist of an electric motor driven fire pump assembly, with an automatic wet-pipe sprinkler system throughout the building.  The wet-piped system will be zoned by floor.  There also includes an automatic dry-pipe sprinkler system in areas subject to freezing.  The fire rating on the structural frame, bearing walls, and floor construction have a 2 hour rating.  The roof construction will have a rating of 1 hour.    

An intelligent analog fire alarm system features the standard alarm notification and ADA visual alarm notification.  The main fire alarm system panel is located inside the main entry.  All strobe lights are wall mounted and use 24V DC synchronized Xenon lamps.  All audible notification devices have a minimum rating of 70db.  The alarm system has a battery backup that can operate eight hours in standby and ten minutes of full alarm action.

Transportation: 

The primary means of transportation for the Tyler School are two passenger elevators that use an undercab hydraulic piston system and are rated at 2,500 pounds each.  The one elevator is located on the south side of the building in the main lobby.  The other passenger elevator and the freight elevator are both located on the north lobby of the building and extend from the basement to the 3rd floor.  There is also a freight elevator using the same system that is rated at 15,000 pounds.  At these two lobby locations there are open stairwells in addition to the elevators.  There are two egress stairwells on the north side and one near the main lobby because the main stairwells are exposed for multiple floors.
