The depleti on of fossil fuels, in combinati on with climate
change, necessitates a transiti on to sustainable energy systems.
Such systems are characterized by a decreased energy demand and an increase in the use of renewables. The objecti ve of this dissertati on is to advance the planning and design of sustainable landscapes, where energy needs can be fulfi lled by locally-available renewable sources. What is important to the designer is to understand the principles by which sustainable energy landscapes can be designed, and how to organize the design process. Three diff erent approaches have been pursued: research for design, research of design, and research-driven design. The study reveals three points of parti cular importance. First, the concept of exergy is criti cal; it draws special att enti on to the quality of energy carriers and the organizati on of sources and sinks in space and ti me. Second, the opti mum scales of energy systems vary and depend on factors such as the quality of the energy carrier and infrastructure. Third, the long-term nature of creati ng sustainable landscapes requires us to go beyond conventi onal planning and design practi ce. The fi vestep framework proposed in this dissertati on can help to integrate current trends and criti cal uncertainti es into the design process.
