2. Peak shaving from ground source geothermal power. Sort the data by month and then sort each month by time of day. Average the power use by the ground source geothermal power unit for each hour of the day using the data for the entire month.
What time of day does the mean peak power use occur for each month (November, December, January, February and March). What is the difference in power use between the time of day with peak power use and the time of day with the least power use? Do a T test for statistical significance of the difference in peak power use and lowest power use for each month.
3. Calculate the difference between the inside and outside temperature (delta T) for the entire data set and save it in a separate column (should be a positive number). Divide the difference between the inside and outside temperature by the power use of the ground source geothermal power unit. For the month of March, calculate the mean value of solar insolation, of delta T, and of the power use of the ground source geothermal unit/divided by delta T for each hour of the day between 630 A.M. and 1630 P.M.
Compare to the times of peak power use for March that were calculated in part 2.
Explain why there are time lags between different variables in the data set in terms
Of thermal mass in passive solar buildings and thermal time constants of these buildings.
8:30 A.M. noon and 4:30 P.M. Why are the slopes and R2 values of each line
different?
