The severity of each spike is indicated by diamond symbols, which correspond to the degree that the most recent data point exceeded the model s prediction. When prioritizing spikes to address, take into consideration both the cost incurred from the spike as well as the degree to which the meter strayed from its model. Least Severe u uu uuu uuuu Most Severe

3 WegoWise has identified a spike. Now what? Discovering the cause of the spike requires a process of elimination. Ask yourself the following questions: Has maintenance work or construction recently occurred in the building? Depending on the type of work that was in progress, it is very plausible that electric, gas or water usage would increase. Has mechanical equipment been replaced or added to the building? A difference in utility usage can sometimes be attributed to a change in mechanical equipment. Has there been a change in occupancy? The number of occupants can directly impact electric, gas and water usage. If you answered No to all of the above questions, then the most recent bill for the meter should be checked for accuracy. It is possible that your utility company has misread your meter and overbilled you, or the bill may be a correction of a previous mistake. On-site staff should check the meter and when appropriate, follow up with tenants. Electric Check for broken or left-on appliances and HVAC equipment, broken or faulty electric meters Gas Check for malfunctioning appliances and gas-fueled HVAC equipment, as well as faulty gas pipes or meters Water Check for leaking or broken fixtures, failing toilet flappers, leaking pipes, incorrectly scheduled irrigation Questions?

Specifically, a weather-adjusted regression analysis of your data reveals the Heating Efficiency of the building is high relative to comparable buildings, which means the building is using too much gas to deliver a given amount of heating Best Median This building: 14.6 Heating Efficiency (btu/sqft/deg/day) Worst Save on Heating: Maintenance of furnaces and boilers can save enough in gas to cover the cost of the service, sometimes in one heating season. Learn about more efficient heating options at furnaces-and-boilers While this analysis uses all available data and rigorous statistical analysis, these recommendations should be viewed *as suggested areas to investigate. Onsite experts will be able to determine if the savings suggested here are feasible. How was this calculated? Utility costs are based on actual billing information (when available) or regional cost averages from US EIA. Median building performance is obtained from the WegoWise database or publicly available datasets, and potential savings is either the difference between this building and the median or a 20% savings for extreme outliers. Recommendations are developed by WegoWise, applying regression analysis where applicable.

7 Is this project saving energy? The chart below shows performance over the 2.5 years since the project was implemented. The graphs illustrate the impact of the project on energy consumption. The baseline model, displayed as a grey line on the graph, represents the projected usage of the building in the absence of the upgrade. This baseline is developed using a five-parameter statistical regression. It is a model of the building s preproject usage pattern, based on historical usage and weather data. The dotted green line shows the building s actual usage and the light-blue vertical line represents the time period in which the retrofit was implemented. The grey shaded area, the fixed-fit window, is the range of data that is used to create the weather-normalized model. How was this calculated? The baseline model employed in this analysis complies with the methodology outlined in ASHRAE (Whole Building Performance Approach), and Option C of the IPMVP protocol. The pre-retrofit baseline model fits sufficiently with the empirical data (R 2 =0.99). The coefficient of variation (root mean squared error) is.9% and net determination bias is 0.01%. 2

8 Is the project on target? During the planning for the project, a target of 20% therm savings was determined. This chart shows the cumulative therm savings for the five years after the project was implemented. The horizontal dashed line represents the five-year target. Five Year Savings Analysis 6,000 Cumulative Savings (Therms) 5,000 4,000 3,000 2,000 Target Savings 1, Projected Savings Versus Target The project has exceeded its five-year 20% target after only 2 years of postretrofit performance. 3
