Transcript Efficiency of Sem II vs Library buildings

Comparing Efficiency
Comparing Sem II and the Library
Building energy consumption
By

If TESC were to use Seminar II building to its
full capacity for classroom use, instead of the
Library would TESC save energy and money
Hypothesis:
1.
2.
3.
Yes, if TESC were to transfer classroom use from the Library to the
modern Sem II building it will save a substantial amount of energy
and money.
No, if classrooms were to transfer from the Library to the Sem II
building barriers created by the features of Sem II may prevent full
use of the building and may actually make it less efficient than the
Library. Thus Sem II may become overloaded making it very
inefficient.
Null Hypothesis, it is impossible to compute classroom usage only
in both Sem II and Library because the barriers with the energy use
breakdown.
Accepted Hypothesis

•
Null Hypothesis
No meters for Sem II
Rough Analysis
TESC Total energy before and after Sem II
Total Energy after – Total energy before=
rough estimate of Sem II energy use.

Energy Efficiency at TESC
Learn to measure and compare energy usage
Provide an understanding inefficiency and
solutions
• Provide TESC with knowledge of energy usage
and ways of conserving energy and money.

Seminar II Efficiency
• Maximum sunlight and easy ventilation
• Minimum volatile compound
• Recycled hardwood, cork floors, natural
ventilation, radiating heat, indirect and natural
lighting.
• Green Roofs, natural reservoir.
• Concrete floor
• 21st century wiring
Library Renovation
• Renovation of B and C
wings
• $21.5 million budget
• To be completed in two
phases
• Begin construction
March 1, 2005
• End construction June

Library Description
•
•
•
•
Named Daniel J. Evans Library
Constructed in 1971
346,969 square feet
Multipurpose building
Renovation Time Line
• March 1, 2005: Construction begins on
Phase 1-C Wing
• October 21, 2005: Construction begins on
Phase II
• June 15, 2006: Construction complete
• Phase I & Phase II Tasks
Factors of Inaccuracy
• Student population
increase
• Temperature variation
• Buildings always
being heated or cooled
• Library computer lab
and size
• TESC entire energy
consumption data
(every building)
• Construction of Sem II
• Modular housing,
dorms
• Swimming pool
