Efficiency Details Graph and Data This graph and table of data provide a more detailed view of each Entity's benchmarked efficiency. The Graph presents the data shown in the Table. All of the Annual figures listed for a given month are a rolling twelve-month total - ie the twelve months- total up to and including that month. A value will only be listed where there is sufficient preceding data. However, unlike for the Efficiency Summary, there is also an option to list Monthly figures and this requires some care in interpretation as mentioned under Aggregation below. First choose the appropriate parameters (beginning with the Entity), and then click the Create Graph button. This brings up a bar graph and a table of data. Parameters: Entity Name: Choose from the dropdown list the Entity you wish to check. Purpose: This displays the Purpose of the Entity you have chosen because all of the comparative data in the graph and table is drawn only from other Entities in the system which have the same Purpose. Data Type: Choose from the dropdown list the type of data required. kWH presents data recording benchmarked energy consumption, CO2 presents data recording benchmarked CO2 emission levels, and DOLLARS presents financial data calculated from the consumption and efficiency information. Indicator: Choose from the dropdown list the Indicator required ?? eg, per square metre, per full time equivalent staff member, per occupied bed day etc. This list??s choices will vary according to the Purpose of the chosen Entity. Aggregation: This defines whether the data you see will be Annual totals or Monthly totals. Please note when you are looking at monthly data that no attempt has been made to correct for seasonal effects. For example, unless a facility has a high summer air conditioning load, it is normal to consume more energy in winter months and these will therefore show as being apparently less efficient than summer months. Year To: Choose the latest month you require. The graph and table will present data for that month or for the previous year ending with that month according to your choice of Aggregation. Output ([kWh or kg]/Indicator): Entity Efficiency ([kWh or kg]/Indicator): This is the Corrected consumption or CO2 efficiency with respect to the chosen Indicator. It is represented on the graph by the yellow bar. Sample Average ([kWh or kg]/Indicator): This is the Corrected average efficiency of all Entities with the same Purpose in the Sample, for the same time period. The Sample covers all other like Entities for which the system is holding comparable data. It is represented on the graph by the middle line (at the light blue to dark blue boundary) in the background hanging bar chart. Sample Worst ([kWh or kg]/Indicator): This is the Corrected efficiency of the worst performing Entity in the sample for the same time period. It is represented on the graph by the top-most extent of the dark blue block in the background hanging bar chart. Sample Best ([kWh or kg]/Indicator): This is the Corrected efficiency of the best performing Entity in the sample for the same time period. It is represented on the graph by the bottommost extent of the light blue block in the background hanging bar chart. Output (Dollars): Additional Cost vs Sample Ave.: This records your additional cost (or saving, if negative) calculated as the difference between the efficiency of your Entity and the average of the sample. It is represented on the graph as the middle line (at the light blue to dark blue boundary) in the background hanging bar chart. Additional Cost vs Sample Worst: This records the ??saving?? (as a negative cost) calculated as your Entity cost less the worst (ie highest) Entity cost from the sample for the same time period. It is represented on the graph as the negative value (or maximum zero if your data is the worst) by the bottom-most extent of the light blue block in the background hanging bar chart. Additional Cost vs Sample Best: This records the extra cost you are paying calculated as the best (ie lowest) Entity cost from the sample less your Entity cost for the same time period. This is represented on the graph as the positive value (or minimum zero if your data is the best) by the top-most extent of the dark blue block in the background hanging bar chart.
