4. You will be redirected to the SRF optimiser site and asked to enter your login details.
5. Once you have logged in successfully, you should see the screen below.
Data Input: All the information entered in the SRF optimiser tool will be saved automatically in this profile and can be accessed at any stage by logging in.
6. Fuel cost input – This section provides default fuel cost values for Diesel (£ per litre), Bio diesel (£ per litre), Electric (£ per kWh), CNG (£ per KG) and LNG (£ per KG) from secondary sources. the values can be changed by clicking on the default cost provided.
7. Macro input – Default discount factor (The percentage rate required to calculate the present value of future cash flow) is provided from a secondary source, user can overwrite their values by clicking on ‘Discount rate‘. The other Macro inputs- Prioritisation, Period, Carbon targets, Fuel consumed, Total distance and Fuel economy are currently disabled in this version.
8. Add new category- Clicking on ‘Add new category‘ will allow users to give a name to their fleet. Naming a category helps in identifying the fleet. For example, a user can name fleets being operated from various depots in the country such as; Depot A (Manchester), Depot B (Livingston) and Depot C (Milton Keynes). The name of the new category will appear on the ‘Data Input‘ page. This name can be edited by clicking on ‘pencil‘ button or deleted by clicking on the ‘X‘ button. The number displayed before the category name shows the number of vehicle types in that category.
9. Add vehicle type- Under a category, user can add their fleet information by clicking on the ‘Add vehicle type‘ button. This will open a form on the right side of the screen to enter fleet profile. The user can specify the characteristics of the fleet in various ways. At the most aggregated level, the user can treat it as a single entry and enter only one row of values. If the fleet comprises one type of vehicle undertaking similar delivery operations this would be the most suitable option. If, however, the user operates a mixed fleet engaging in different types of distribution, it would be advisable to differentiate the various classes of vehicle and/or distribution operation by clicking ‘Add vehicle type‘. If the user operates a small fleet, they may even wish to enter data for individual vehicles, each listed on a separate row by adding more vehicles through ‘Add vehicle type‘.
The table below provides more detail on the vehicle type inputs-
10. Click ‘Submit‘ to enter a vehicle type or ‘Cancel‘ if you don’t want to enter a vehicle type.
11. A vehicle type can be edited by clicking on the ‘pencil‘ button or deleted by clicking on the’X‘ button.
12. Once the user has entered the data in the ‘Data Input‘, the next step is to click on ‘Calculator‘
Calculator: This page generates a list of carbon-reducing measures based on the input given by the user in the ‘Data input‘ section. This page displays a list of prioritised carbon-reducing measures based on Net Present Value (NPV) under each vehicle type generated using the secondary data of each carbon-reducing measures. The values associated with the carbon-reducing measures are calculated independently. The selected saving measures summary on the right side of the screen shows cumulative values from selected carbon-reducing measures.
13. The user can include measures for reporting by clicking on the checkbox under ‘Include Intervention’, highlighted in yellow in the image.
14. Selection of carbon-reducing measures will generate a graphical summary on the right side of the screen. This summary displays cost saving current year (£) cost saving over 3 years (£), fuel saving per year (litres), energy saving per year (kWh) and reduction in carbon emissions (KGCO2) associated with all vehicle types.
15. At any point, the user can remove selected carbon-reducing measures by de-selecting the checkboxes selected in the ‘Include Intervention‘ column.
16. A description of carbon-reducing measure can be found by clicking on the ‘Question Mark‘ icon next to each measure on the left hand side of the table.
17. To edit the default values associated with the carbon-reducing measures, click on ‘Advance Tuning‘ tool. The user can see the default values of each measure, customise the results by overwriting default figures by adding their own cost and carbon figures.
The carbon reducing measures related to the following alternate fuel vehicles are calculated using base vehicle type entered in the ‘Data Input‘ step.
- Increase use of electric vehicles
- Increase use of hybrid vehicles
- Increase use of biodiesel vehicles
- Increase use of dual-fuel vehicles – Diesel and CNG/Diesel and LNG
- Increase use of dedicated gas vehicles – CNG/LNG
In order to change default fuel substitution, the user can overwrite expected primary fuel% substitution in ‘Primary fuel %‘ textbox for biodiesel and duel-fuel vehicles. Click on ‘Submit‘ to save new figures.
Reporting: The selected carbon-reducing measures in ‘Calculator’ page are displayed as a report. The user should click on the ‘Reporting’ button to access the report.
The report can be customised by adding ‘Name of Organisation’ and ‘Total energy consumption assessed’. Upon entering the customisation details in the fields marked ‘please enter’, a user can then download the report by clicking on ‘Export to xps’. This will create a spreadsheet for filing and further use.
