ETA+ is a startup in the area of building and infrastructure management to reduce energy consumption and following that green gas emissions. More than 40% of all CO2 emissions are generated by building, much more than traffic, logistics or transportation. ETA+ segments the building market into three major segments, MDU (multi dwelling units), Public (public buildings, especially schools, kindergartens, etc. and Office, buildings which are used by more than one tenant. If you compare those three segments, all of them have nearly the same emissions (~ 2 b square meters with about emissions of ~ 120 kWh with emissions of 250 g | kWh) 1.200.000.000 t of green gas emissions, only in Germany. The vision of ETA+ is net zero emissions for every building.
