Action Sets Evaluation
Local administrations can use the ACCENT tool to support them in the construction of an energy strategy (SEAP) by means of mapping and scenarios interfaces. In case the SEAP is already defined, it can be directly incorporated in ACCENT.
Through the Action sets evaluation, users can check, modify and manage their previously defined building selections, using the same tool previously explained in the mapping functionality section. The tool allows comparing set of actions chosen by the user from a predefined catalogue, and applied to the previously defined selections. This new set of actions are evaluated, and the engine returns the estimated gains of final energy consumption, of GHG emissions, the total investment required, savings on energy costs, etc. A comparison function enables to assess the benefits of each set of actions as it’s shown in Fig. 3.
As buildings are changing over time, data must be stored for the different periods. Distinct building evolutions are possible over time, which represent different
Fig. 3 Action sets evaluation functionality screen timelines from a beginning year. The mapping functionality shows the actual state of buildings of the city. Scenarios are intended to evaluate and to plan actions over time. It can so be seen as one potential evolution of the buildings from the city based on one reference year of Building stock.
The most interesting actions set can be selected and transferred to one specific scenario, while the actions can then be distributed over it. So when a scenario has to be evaluated, the system has to consider in one hand the buildings in the scenario timeline for those impacted by one or several actions, and in the other hand the buildings in the building stock timeline, at the scenario reference date, for all others.
Through the construction, analysis and comparison of different scenarios, the tool allows taking decisions and defining strategies based on objective and well-founded criteria.
As it’s presented in Fig. 4, analysis tab permits to assess the gains (Energy consumption, GHG emissions, and savings), data investment (payback period and rate effort) and energy consumption savings evolution along the implementation of the actions included in the scenario.
Connection with Other Cities
This functionality, specifically designed for cities, enables them to share and benefit from other cities feedback on specific actions. The city manager of the tool can decide to publish information on the ACCENT network. The information could be regarding a specific action, scenario and/or strategy. Different types of sharing
Fig. 4 Scenarios functionality screen settings have been defined (with a group of other cities, on public website). Comments highlighting successful practices and systems, or difficulties arisen during the implementation can be linked to the published actions in order to work for the common good of energy efficiency along with other cities.
