Students Excel in Design

October 11, 2010

ATLANTA - The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) announced the winning entries in its 2010 Student Design Competition. This year’s competition featured a mock design of the Ginsburg Tower at Florida Hospital in Orlando, Fla. This structure, the tallest hospital building in the state, is a 15-story patient tower that contains the Florida Hospital Cardiovascular Institute, 440 patient beds, and one of the largest emergency departments in the country.

Among the 31 entries from around the world, three in particular stood out as first place winners in the three categories that the competition offers.

First place in HVAC System Design was awarded to Nathaniel Boyd, Michael Angell, Justin Wiese, Edward Gillett, and Trong Duc Nguyen of the University of Central Florida (Orlando, Fla.). The team was advised by Marcel Ilie, Ph.D.

After constructing a complete building information model (BIM), the students chose a constant volume air-handling unit as the primary air source and latent load control, and onsite combined cooling, heating, and power (CCHP) plant based on a bank of micro-turbines fueled by natural gas. These HVAC systems eliminate nosocomial infections via proper ventilation directional control and would provide uninterrupted HVAC service to hospital occupants, even during natural disasters, as well as reduction of environmental and economic impact of the HVAC design.

First place in HVAC System Selection was awarded to Matt Kolins, Joel Wheeler, Nicole Vogt, Jared Palan, Todd Kuno, and Zac Buckmiller of Kansas State University (Manhattan, Kan.). Their faculty advisors were Fred Hasler, PE, and Julia Keen, PE.

The students selected a combination of air-handling units with patient room heat pumps, chillers and cooling towers, and shell-and-tube heat exchangers. Additionally a geothermal loop in Lake Estelle, adjacent to the hospital, acts as a heat sink. Not only is the system environmentally conscious, but also has the best return on investment.

First place in Integrated Sustainable Building Design was awarded to Ryland Phelps, Carolyn Lamb, and Amy Rose Keyzer of Lawrence Technological University (Southfield, Mich.). Their advisors were Daniel Faoro and Janice Means.

The students set out to design a sustainable and energy-efficient building without sacrificing visual appeal, while responding to climate conditions and surrounding buildings and forms. They were able to achieve this by using water-reducing fixtures in all bathrooms, supplying alternative energy through photovoltaic panels and architectural fabric, using geothermal wells and evacuated tubes to reduce loads on mechanical equipment, and implementing a daylighting system to reduce lighting loads and bring daylight into the building.
