The autarky level measures how much of its energy needs a building can meet independently, without relying on external sources. A higher autarky level indicates greater self-sufficiency, with 100% meaning complete independence from the grid.
Higher self-sufficiency
Benefits: Greater energy independence, lower long-term costs, reduced environmental impact and net zero possible.
Limitation: Higher upfront cost, requires more storage space.
Lower self-sufficiency
Benefits: Lower initial cost, less storage space needed.
Limitation: Exposed to energy market fluctuations, higher reliance on the grid, potential long-term cost increases, larger carbon footprint.
