Comparing Efficiency

Comparing Sem II and the Library Building energy consumption

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. 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.

2. 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.

3. 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.

Promote Energy Efficiency

• Promote energy efficiency to its full capacity• 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.

LEED

• U.S. Green Building Council (USGBC) and Leadership in energy and Environmental Design

• Consensus-based national standards for sustainable buildings, adaptable to new processes and technology.

• Site Sustainability, water and energy efficiency, materials and resources, indoor environmental quality, innovative technology

Seminar II

• 160,000 square feet• Five cluster building • Finished spring 2004• $44 million dollar

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

Conclusion

• Sem II is more efficient than the library

• Natural Gas consumption hardly effected

• Sem II uses less electricity than the Library

• Sem II = 2.1 kwh/square foot

• Library = 10.8 kwh/square foot
