Other Problems Solved

Benchmark v Actual Operating data of a loaded site showed

higher PUE than Cx data Normally, we get BETTER operating

Recommendations

Measure PUE Daily manual reading is sufficient Push operating data up and down the chain

Operators are best users of data Don’t forget design teams that built the site

Be careful with absolute comparisons or metrics

Share your data and discuss with your peers
