soojuskao
Soojuskao is a term used in speculative energy systems to describe an integrated, low-temperature district heating approach that combines solar thermal collectors, heat pumps, and seasonal thermal storage to meet building heat demand while minimizing fossil fuel use. The concept emphasizes modularity, energy flexibility, and the incorporation of waste heat within urban energy networks.
The name draws on the Estonian word soojus, meaning heat, and adds a coined suffix -kao to
Design principles include three functional layers: capture of renewable and waste heat, thermal storage to balance
Origins and usage: Soojuskao appears in speculative design and academic exercises about future cities. It is
Applications and limitations: Potentially suitable for retrofitting historic districts or developing eco-districts; benefits include reduced peak
