Arc uses, for example, the input data from the LEED Online instrument (the building data can be directly imported from LEED Online into arc) and supplements these with real performance data, e.g. in accordance with the boundary conditions of the LEED existing building certification, Version v4.1. Arc uses data from various sources – including energy consumption data, indoor air qualities, water consumption data, waste streams, mobility concepts and the well-being of the building users. An assessment with up to 100 points is possible. If required, the results can be made public on mobile devices or digital display panels.
