European Solar Prize 2015 goes to Aktiv-Stadthaus, Frankfurt am Main
The “Aktiv-Stadthaus” by ABG Frankfurt Holding is the first and largest inner city multiple home residual building to receive the federal energy-efficiency-plus certificate. This means that the building, which contains 74 apartments, generates more energy than its residents consume. More than 1000 façade and rooftop mounted solar modules generate 300,000 kWh/a of green electricity, while a sewage heat pump generates hot water and powers the floor heating. Latest energy efficiency structures minimize energy losses. Excess energy is stored in a large 250 kWh battery and is used to charge a fleet of shared electric vehicles. Being developed in cooperation with the federal research initiative “Zukunft-Bau” (Construction Future), the building also serves as a proof of concept – for the first time, findings and practices from single-family energy-plus homes have been successfully applied to a large scale residential apartment complex. The design by HHS Planer + Architekten demonstrates that the future of housing can be ecofriendly, economical and aesthetic.
