  1. DUC Energy Budget Sarah Canniff, Brittany Huhmann, T. J. Pepping, Elliot Rosenthal, and Dan ZernickowEECE 449, Spring 2010

  2. Project Objectives • Find total energy use, CO2 emissions, and cost for natural gas, electricity, hot water, and chilled water in the DUC for one year • Identify the portion of the DUC’s total energy use that goes to individual components of the HVAC system and the portion that goes to non-HVAC uses • Identify daily, weekly, and seasonal trends in the above parameters • Identify trends between outdoor temperatures and student use of the DUC on these daily, weekly, and seasonal trends

  3. Approach and Methodology • Data from Metasys for 5:00 PM April 16, 2009 to 5:00 PM April 16, 2010 • electricity, natural gas, hot water, chilled water • supply fans, relief fans, and heat recovery fans for the 3 AHUs • pumps for hot and chilled water • outdoor air temperature • All energy data converted to MBTUs for comparative purposes • Assumption: Zeros are real and included; “no data” was not included

  4. Results: Natural Gas

  5. Results: Electricity

  6. Results: Hot Water

  7. Results: Chilled Water

  8. Results: Four-Streams

  9. Summary and Conclusions • Total energy (17,300 MMBTU), CO2 (2,140,000 kg), and cost ($126,000) for one year • Electricity is biggest source of energy consumed (36%), CO2 emitted (67%), and cost (52%) • HVAC electricity is 29% of total electricity consumption • Two peaks daily in energy consumption corresponding to lunch and dinner rush • Lower energy consumption on weekends vs. weekdays & during breaks (summer, Thanksgiving, winter, spring) • Recommendations for reductions
