Building Overview​
​
The Gettysburg CARF although a modern design, it incorporates brick that helps blend the building with the historical campus. The building is a single story facility that offers a variety of functions that the students, athletes and teachers can enjoy. It functions as a training, competition and classroom for the collegiate athletes in the fall and spring seasons. It also functions as an athletics, spiritual, and academic area in the summer for regional youth group camps. The entrance of the building includes an 80 ft tall triangular glass structure, where a 35 ft tall climbing wall sits inside. The CARF also includes a 20,000 SF natatorium that features a mezzanine that holds 350 spectators, an 8 lane competitive pool, and a 5 lane warm up pool. Other major areas include a weight and fitness room, along with a multi-purpose space that is used for aerobics, yoga, and martial art classes.

Sustainability Features
​
The Gettysburg CARF contains many significant sustainability features that make this building LEED Gold certified. One of the main attractions to this building is the tower. The tower is used as a thermal chimney that uses 100% of outside air for natural ventilation in order to cool the space when the climate conditions permit. At the top of the tower there are dampers that are activated by temperature sensors that will allow cool air to circulate through the tower. Energy recovery ventilation units were also used to help reduce the mechanical energy demands. The CARF included variable frequency drives, in order to help with energy costs and savings. Another feature the CARF installed was a water efficient filtration system and low-flow showerheads that minimize the size of the domestic hot water plant.
The CARF incorporates many day-lighting strategies in areas such as the fitness center and climbing wall area. These include southern facing glass, solar shading, light shelves and internal windows, in order to take advantage of natural lighting. These designs also allow for solar gain in the winter and help to minimize heat gain in the summer.

Primary Engineering Systems:
Construction
​
The Gettysburg “CARF” Center for Athletics, Recreation, and Fitness started construction in June 2008 and was completed in Fall 2009. The contract type is a design-bid-build. The job included a 55,000 SF fitness area, multi-purpose room and natatorium; along with updates to the central energy plant that cost around $22.4 million. A key factor that the construction proceeded to do was to interior excavate up to 8,000 cubic yards of material in a little over two weeks. This allowed work to proceed through the winter and to avoid any scheduling concerns. The project was also completed with no recordable injuries or safety violations.
Mechanical
​
The Gettysburg College has a central plant that supplies chilled water and steam to the CARF. The campus was at capacity for chilled water and steam. As a result, repairs were made to the steam and condensate piping to fix leaks that were causing energy wastes. Extensions of the piping for steam, condensate, and chilled water were also added in order to serve the CARF. The chilled water coming into the CARF flows to the chilled water pump and then supplies the three rooftop units and two energy recovery units. The steam coming in from the central plant goes to the shell and tube, 4,740 MBh heat exchanger, which turns steam into hot water, where it then goes to the hot water pump and from there it supplies the three rooftop units and two energy recovery units. There is also a swing pump, which acts as a backup for the chilled water pump or the hot water pump. The three rooftop units can hold a total cooling capacity of 1,385 MBh. The two energy recovery units can handle 99.5 MBh of cooling and 71 MBh of heating. In the summer months there is no campus steam, so to accommodate reheat loads the CARF uses the 2,000 MBh gas fired boiler for hot water.
The pool area has two heating and cooling units that have a combined condenser capacity of 1,700 MBh, each having their own air cooled condenser unit that has a heat rejection capacity of 600 MBh. Hot water is supplied to the pool heating and cooling units from a separate plate and frame, 1,378 MBh heat exchanger that operates water to water.
Lighting/Electrical
​
The Gettysburg CARF has a variety of lamp types throughout the building. The majority of the luminaires are compact fluorescent and fluorescent lamps. However, there are also some halogen, LED, metal halide, metal halide pulse start, quartz, and xelogen lamp types. The majority of the rooms also have occupancy sensors installed.
The building is powered via a 277/480V 15 kV main switch, which feeds the primary side of a 13.2 kV, 1500 kVA transformer. A 277/480V 2000A building main distribution switchboard is fed from 277/480V secondary main transformer and feeds the other panels throughout the building. The building also has a 30 kW natural gas emergency generator, that serves the automatic transfer switches and emergency panels that are associated with them.
Structural
​
The Gettysburg CARF is a steel framed structure. The building has two different slab depths; 12” slab on grade for under the pool and 5” slab on grade throughout the rest of the building. The CARF has a variety of wide flange beam sizes that support the roof of the fitness area, locker rooms, and lobby area. The most common wide flange beams being W14x22 and W21x44. The natatorium has long span joists girders that support the roof. The tower that is located at the main entrance of the building is made up of different size HSS columns. The lateral system is primarily made up of steel braced and moment frames, as well as concrete shear walls.
Additional Engineering and Support Systems:
Fire Protection
​
The Gettysburg CARF abides by the latest codes set forth by the National Fire Protection Association (NFPA 13, 2006 International building code). The entire building is fully sprinkled with a system combined with wet and dry pipe sprinkler and standpipe system. The wet pipe sprinkler system has the automatic sprinklers provided throughout the entire building. However, one part of the building, the climbing wall, has a deluge water curtain for the fire protection. The Gettysburg CARF is also equipped with smoke detectors and a fire alarm that is wired throughout the entire building. Fire dampers are also installed at the penetration of fire rated walls.
Transportation
​
The Gettysburg CARF has one elevator for spectators to be able to watch, from the mezzanine level, competitions that are happening at the Natatorium. There is also a nearby staircase that spectators can use or in case there is a fire. The CARF also has two main entrances to the building; one plan South, next to the climbing wall, and one plan North that enters into the main lobby area. A third entrance is also available plan West, entering the dryland training area. There are also two other entrances plan West. One entering right into the fitness area and the other near the mechanical room where athletes and students can make their way to the locker room area.
Telecommunication
​
The Gettysburg CARF has two telecommunication rooms, one in the fitness area and the other in the main north lobby area with telecommunication lines running through the entire building. The intercom system runs through the CARF along with wireless internet that students and athletes can access. The CARF also has a security system that is wired through the building where facility workers can properly arm and communicate with the building in order to maintain building safety.
