2012-2014 Normalized Data vs. Actual Data (Total kWhs) 2012 2013 2014 4,700,000 4,500,000 4,300,000 5,100,000 4,900,000 Normalized Totals Actual Totals The visual below shows the actual electricity (kWh) used by buildings that were included in the weather- normalization analysis for 2012-2014. As shown, Alpine Bank experienced a reduction in kWhs during that time (4,865,770 kWhs in 2012 vs. 4,510,569 kWhs in 2014). Almost all of this reduction was driven by the Grand Junction tower, which reduced its kWh usage from 2,358,221 kWhs to 2,098,553 kWhs. Because there is little correlation at any location between cooling degree days and kWhs for years 2012-2014, the expected electricity usage is generally level 2 . 2 Only Clifton and Delta locations showed a correlation between cooling degree days (days when air conditioning would need to be utilized) and kWhs. 2012-2014 Normalized Data vs. Actual Data (Total Therms) 160,000 140,000 120,000 100,000 2012 2013 2014 220,000 200,000 180,000 Normalized Totals Actual Totals 1 The following locations were not included in the 2012 overall analysis because they opened after January 2012: Denver – Cherry Creek, Denver – Union Station. Therefore, no 2012 baseline exists for these sites. The visual below shows the actual natural gas usage (therms) used by buildings that were included in the weather-normalization analysis for 2012-2014 1 . As shown, Alpine Bank experienced an increase in therms between 2012 and 2014 (142,134 therms in 2012 vs. 152,050 therms in 2014). In addition, you will see a blue line which represents normalized energy use. Weather- normalized energy is the energy the building would have been expected to use under similar weather conditions as the base year. In 2014, due to the weather, it was expected that Alpine Bank would have used more therms (154,392 therms) than were actually used. Therefore, some of the increased usage between 2012 and 2014 can be equated with the weather. 16
