7. University of Maryland’sGossett Field House College Park, MD Existing Air Side System Renovation Section: • AHU - 1 – Serves 2nd floor office space • AHU – 2 – Serves 1st floor - 100% OA unit with no energy recovery • Duct mounted hot water booster coils Jason Borowski Architectural Engineering Mechanical Option Pennsylvania State University

8. University of Maryland’sGossett Field House College Park, MD Existing Air Side System 2nd Floor Addition Section: • Six Packaged Rooftop Units - 3 CAV Units - 3 VAV Units • VAV boxes with hot water reheat coils used as terminal devices • Air flows from 1400 – 10000 cfm Jason Borowski Architectural Engineering Mechanical Option Pennsylvania State University

9. University of Maryland’sGossett Field House College Park, MD Existing Water Side System • Air Cooled Liquid Chiller – 270 tons • Steam to HW Heat Exchanger – 110 gpm • Two Chilled water pumps – 650 gpm, 15 hp • Four hot water pumps - 80 gpm, 1 ½ hp - 25 gpm, ¾ hp Jason Borowski Architectural Engineering Mechanical Option Pennsylvania State University

10. University of Maryland’sGossett Field House College Park, MDMechanical Redesign • Convert to Central Plant Operation - Steam/HW Heat - Chilled Water • Use Sensible/Latent Energy Recovery Ventilators to Reduce Load on Central Plant • Use VAV boxes with reheat for all terminal devices Jason Borowski Architectural Engineering Mechanical Option Pennsylvania State University

11. Minimize First Cost Difference Reduce Annual Operating Costs Create a more Homogeneous System Jason Borowski Architectural Engineering Mechanical Option Pennsylvania State University Eliminate Gas Fired Heat Make use of Resources Available Minimize impact on other Building Systems Minimize impact on Steam Plant University of Maryland’sGossett Field House College Park, MDObjectives of Redesign
