Calculator optimisation of energy consumption in private homes
The API that Totalkredit is using for their Energy calculator has new available data concerning energy labels.
Customers can use the calculator to get proposals for projects that would improve their energy consumption, and to figure out how these improvement would be reflected in an energy label. Just as providing a clear picture of cost benefit.
In this regard, the current calculator (2022 version) needed at redesign to embrace the new functionality.
My role
My role was to faciliate meetings with Business analyst, developers and API providers to figure out the best way to rebuild the software, and get a strong common focus on what we wanted to achieve with the calculator. Create wireframes and contuct user tests to ensure is was done right.
