Firm name: Barton Assocs. Inc.
Project building name and location: Gettysburg College; Center for Athletics, Recreation & Fitness (CARF), Gettysburg, PA
Type of building and type of project: School/athletic facility, New Construction
Project completion date and project duration: Project completed: 2009 Project duration: 13 months
Engineering challenges and solutions:
- The campus electrical service was at its maximum without primary service upgrade (at a cost of several million dollars). Solution– Upgrades to the central chiller plant to replace inefficient air-cooled chillers with water-cooled centrifugal chillers with variable speed drives and free cooling (without the need for compressor operation). As well as upgrades to the central steam plant including repairing steam and condensate distribution piping to fix energy-wasting leaks and also extended the piping to serve the new building and provide hot and chilled water to an adjacent building.
- The campus steam and chilled water was at its capacity. Solution – same as above.
- Heating/cooling the tower. Solution- A thermal chimney that uses 100% of outside air to cool the space during certain ambient conditions.
- Very expensive water in Gettysburg Borough. Solution- installed water efficient filtration system as well as low flow fixtures in CARF and adjacent buildings such as:
- New high-efficiency water tube re-heat boilers to eliminate the need to run a large boiler plant during the summer months to accommodate re-heat loads
- New low-flow showerheads throughout the existing field house to decrease demand for domestic hot water and minimize the size of the domestic hot water plant needed to serve the new facility.
- Daylighting strategies including southern facing glass, solar shading, light shelves and internal windows to optimize natural lighting and solar gain in the winter and minimize heat gain in the summer.
Barton provided mechanical, electrical and plumbing design services for a 10,000 square-foot renovation and a 55,000 sq-ft addition to the College’s existing sports and recreation facility. The addition included a new weight and fitness room, athletic training room with a Hydroworx therapy pool and a natatorium with eight competition lanes, a five-lane warm-up pool and 350-seat spectator gallery. The project also included infrastructure improvements such as the relocation of campus utilities and updates to the campus central plant, as well as the design of energy-efficient systems such as centrifugal chillers, high-efficiency water tube re-heat boilers and daylighting and water conservation methods.
The most significant feature of this facility is the rock-climbing wall enclosed by an 80’ thermal chimney used to provide natural ventilation and cooling. This project achieved LEED Gold certification from the U.S. Green Building Council as well as the McGraw-Hill 2010 Mid-Atlantic Higher Education Project of the Year.
