"PV system integrated into the modular facade for supplying energy, a mini heat pump for heating and cooling, and a decentralized ventilation unit with heat recovery... 25 to 30 percent of all office buildings in Germany together consume 3200 gigawatt hours (GWh) of electricity each year. Using our RE modular facade would reduce this to 600 GWh"
