Conclusions
> Lighting
The lighting successfully enhanced the architecture while not adding more clutter or
elements to the spaces. It also helped to create a natural eye flow throughout each space.
> Electrical
The motor control center consolidated the various motors into one unit and saved space on
the penthouse floor. It is also located in a central location within the penthouse to minimize
wiring.
> Structural
Opening the second floor to the first floor increased the atrium height to almost 70 feet. It
helps to create a sense of flow from the ground floor through the fourth floor and provides
more daylight to the ground floor instead of giving the first floor a basement effect.
> Mechanical
The effects of the glass material on the mechanical load can make a significant difference in
equipment sizing and also operational costs. The effects of opening up the second floor
also impacted the mechanical loads.
QUESTIONS?
I would especially like to thank the following for all of their support throughout the past 9 months:
The John Hopkins University for giving me this invaluable opportunity to study one of their most unique and
high-tech buildings on their campus.
Helen Diemer, Pomme Suchato, Emad Hasan and the rest of the Lighting Practice.
Christie Trexler-Cari from Ballinger for all of the help and quick responses to RFIs.
Dr. Mistrick, Professor Dannerth, and Dr. Houser, Professor Holland and Professor Parfitt in the Penn State
Architectural Engineering Department.
Corey Wilkinson for fixing any and all computer related problems!
My AE classmates for providing me sanity and enjoyment throughout the process and for making pacts together.
Specifically, thank you to Leah Clare, Karstan, A Dubs and the rest of the L/E option for the L/E advice, Sanfor for
the structural advice, the Mechanical option for the mechanical advice and the thesis major, Mayor Tost for keeping
my stuff safe. Also, a thank you to TBA, my Thesis Buddy Ashley!
My Friends for All being Understanding and supportive after I became a hermit for the past 3 months.
Last but definitely never least my family, for supporting me and for understanding when I did not come home for
spring break and did not stay all of Christmas break because of my thesis.
