2 CUMMINS CONFIDENTIAL Goals  Calculate HDD  Furnace on time  Number of on-off cycles  Heat Loss  Correlate Data

3 CUMMINS CONFIDENTIAL HDD & Furnace On Time Date HDD Calculated HDD Actual % Error Furnace on Time # of On-Off Cycles Calculated # of on- off Cycles Seen on Graph Difference Btwn Calc and Graph 1/ % / % / % / % / % / % / %

4 CUMMINS CONFIDENTIAL HDD Calculated Vs. HDD Published

5 CUMMINS CONFIDENTIAL Furnace On Time Vs. HDD Calculated

6 CUMMINS CONFIDENTIAL Furnace On Time Vs. HDD Published

7 CUMMINS CONFIDENTIAL On – Off Cycles

8 CUMMINS CONFIDENTIAL Calculated On/Off Cycles Vs. Observed

14 CUMMINS CONFIDENTIAL Heat Losses Date Avg. T- Out Delta T Wall Heat Loss Window Heat Loss Door Heat Loss Total Heat Loss 1/ / / / / / /

15 CUMMINS CONFIDENTIAL House Heat Loss Month Heat Loss BTU/hr Heat Loss Therms/mo nth BTU/day Therms/da y BTU/month Therms/mo nth December January February March

16 CUMMINS CONFIDENTIAL Conclusion  HDD calculated vs. HDD published strong correlation and minimal error.  Excel program was modified to yield accurate furnace on/off calculations  Furnace on time vs. HDD & calculated vs. HDD published showed a poor correlation.  House Heat loss calculations yielded reasonable results.
