The objective of the design project was to somehow change the East Residence Halls of Penn State University in order to make them more eco-friendly and energy efficient. The current dorms do not contain many eco-friendly features, and they aren’t following the trend of “going green.” There is not currently a huge push for students to recycle within the dorms, and they are not energy efficient in any way. The idea behind the process itself is to follow the green engineering design process, which will help create sustainable solutions and renovations to the dorms. As in any design process, the first step was to complete customer needs assessments. From these assessments, we were able to create weighted tables to see how important everything is, which helped us in the concept generation phase. We generated concepts and put them in a morph chart, and then from there, we implemented TRIZ systems to help further identify the problem and come up with solutions. The last step in the process was to select materials and finalize the design. This was done with the help of SolidWorks, because using a few of the programs, we were able to see how materials would be more or less eco-friendly and sustainable. We tried to pick the most eco-friendly ones on the market that would still meet the needs of the consumer, since the whole idea behind the redesign was to make it more eco-friendly.

There are two EMS models shown below. One is the initial EMS model that shows the problems with the current dorms, and the second is the revised EMS model we made to show how we planned to fix the problems.

Winning Concept – Changes to be Made: 1.Motion sensor lights to be added in hallways and bathrooms to reduce wasted energy.2.Solar roof panels to help regulate temperature control.3.All LED or solar lights to have more energy efficient lighting. 4.Increased window size in dorms for more natural light, with an added tint that helps absorb or reflect the sun’s rays (heat) depending on the temperature.

The window film show to the right is one of the most economically advanced technologies we’re putting in the dorms. The tint traps heat in the winter and rejects heat in the summer to help regulate temperature and lower the cost of heating or cooling the entire building. The tint also improves the clarity and visibility through the window and reduces the glare.
