19 Summary Toursim is important part of regional added value chain High water and energy demand of touristic facilities Way to improve efficiency: 1. Decrease energy needs and energy demand 2. Make energy demand and energy supply more flexible 3. Increase renewable and decentralised energy supply Knowledge of energy and water flows is key Coupling destination and facility to fulfill regional, national and global energy and environment targets UNI KASSEL upp Henning Meschede, M.Sc. 19
