Sustainable Technologies


Solar Panels


Geothermal Heating/Cooling


Rain Water Collection


Green Roof


Solar Panels


Utilize a large grid
-
tied system


Allow energy to be sold into the grid at low
consumption times


Avoid large battery bank; making the system
easier to maintain and more eco
-
friendly



Wirelessly monitor through a
PC/Website


36 kW tower system consisting of 6
inverters and 180 panels




Geothermal Heating/Cooling


Vertical closed
-
loop system was
developed by the mechanical group.



Reduce the Heating/Cooling

costs and earn LEED credits



Rainwater Collection


Rainwater to be collected only from the
main roof


20,000 Gal. tank proposed


Irrigation to be north and west of building
(Hatched area on following slide)


No potable water will be needed for
irrigation


Green Roof


Located on top of auditorium. Entrance

on 3
rd

floor of main building


Green roof will feature extensive

vegetation


Extensive vegetation is lighter and

requires less soil, thereby

reducing the load (saturated load

approximately 34 psf)


Will feature walkways and tables

for occupants to enjoy


Research Labs


Civil Experiments



Pervious Pavements



Green Roofs


Mechanical Experiments



Electric Motors



Hydrogen Fuel Powered Engines



Green Heating and Cooling Systems


Electrical Experiments



Smart Grid



Wind Turbines



Solar Panels




Storm Water Collection



LEED Design Techniques


Interior Concept


Exterior Plan

Utilize Kalwall Translucent

Daylighting Systems



Minimize need for
artificial light


Panels provide low
solar heat gain and
high insulation values


Made from 20%
recycled content




Exterior Plan


Glass


Strategically use windows to keep occupants in
touch with outside world while providing natural
light

Floor Beams


Located on the 2
nd

and 3
rd

floors


Designed to support metal decking with

concrete cover


Uniform distributed load on entire beam


Max load case: 1.2D + 1.6L


The beam was designed for the maximum
bending moment


Allowable deflection controlled beam selection




Interior / Exterior Girders


Designed using end reactions from
connecting floor beams


Point loads at girder/floor beam connections


Max load case: 1.2D + 1.6L + .5S


2 Typical interior and 2 exterior were
designed


Allowable deflection controlled girder
selection




Columns


Designed using axial loading from SAP
2000 analysis


Max load: 1.2D + 1.6L + .5S


3 Typical columns (Locations on next slide)


Main exterior (Red)


Main interior (Blue)


Auditorium (Yellow)


Maximum axial load controlled column
selection

Auditorium Green Roof


Designed to support saturated green roof


Distributed load on entire joist


Max load case: 1.2D + 1.6L + .5S


Max span: 85 feet


Long span LH series roof joist


Allowable distributed load controlled selection



Main Roof System


Designed using supported tributary area


Distributed load on entire joist


Max load case: 1.2D + 1.6L + .5S


Max span joist: 70’


Max span joist girder: 34’


2 typical joists and 1 joist girder designed

-
roof components (per UT guidelines)


Metal decking


SEBS base sheet


Type 6 glass felts



Main Wind Force Resisting System


Based on ASCE 7 provisions


Wind Load Factor = 1.6



(LRFD Combinations)


3 wind braces to resist East
-
West winds


2 wind braces to resist North
-
South winds


3 designs to accommodate structural
differences in the building



Wind Brace Locations

N


Typical Wind Brace


Foundation Selection


Loadings obtained from SAP Analysis of the
building


Pad footings with integrated auger cast piles
were selected


Pad footings and piles required less concrete
than strip or mat foundations


The piles transmit some load to more stable
clays below grade


Four typical pad footings were designed to
increase efficiency





Footing Design


Soil info was obtained from boring logs of
Scott Park


Estimated bearing capacity of 4 kips/sq ft for
the soil


Foundation size and number of piles
determined by loading and bearing capacity


Designed for one and two way shear to obtain
sufficient depth for the reinforcing steel of the
foundation

Take Home Message


Place UT at the forefront of researching
sustainable technologies


Create a learning environment for both
students and the public




Provide a recognizable


high performance building


to showcase UT’s sustainable efforts
