Using energy losses and structural resources of existing buildings


The idea is to use settlement pressure on urban agglomerations in order to foster refurbishment of existing buildings and to increase decentralized renewable energy production. New living space is created “on top” without further land sealing and it works as a symbiosis where the full potential of old and new unfolds. Renewable energy is produced on the symbiont, changing the building’s role in the energy network. When put on the market and sold or rent the symbiont creates financial benefit which can be used to refurbish the existing building and make it a “Plus-Energy House”.
