Engineering practices such as BIM, geothermal and combined cooling, heating and power were highlighted in the winning entries in the 2010 ASHRAE Student Design Competition.

The 2010 ASHRAE Student Design Competition featured a mock design of theGinsburg Tower at Florida Hospitalin Orlando, Fla. The tallest hospital building in the state houses 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 first place winners were chosen in three categories.  

First place in HVAC System Design:Nathaniel Boyd, Michael Angell, Justin Wiese, Edward Gillett and Trong Duc Nguyen, of University of Central Florida, Orlando, FL. Their faculty advisor is 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.

First place in HVAC System Selection:Matt Kolins, Joel Wheeler, Nicole Vogt, Jared Palan, Todd Kuno and Zac Buckmiller, of Kansas State University, Manhattan, KS. Their faculty advisors are Fred Hasler, P.E. and Julia Keen, P.E.

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:Ryland Phelps, Carolyn Lamb and Amy Rose Keyzer, of Lawrence Technological University, Southfield, MI. Their advisors are 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. This was achieved 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.

The three teams will present their projects at the 2011 Winter Conference in Las Vegas, Jan 29-Feb. 2.
