2. Community Approach: Background
Cities …
Cities consume 60 to 80% of energy demand worldwide
Buildings …
Focus of research in recent years: technological innovation and improvements
Communities …
Transition - from optimization of building parts via single buildings to optimized solutions for whole neighborhoods and communities, but …

5. Case Study / City of Salzburg, Austria
Main performance criteria
Low energy standard for buildings (20/30 kWh/m² and year)
Energy efficient pumps and lightning of public areas
High rate of renewable energy (> 30% in addition to available district heating system powered by Biomass/Gas CHP and industrial waste heat sources)

6. Case Study / City of Salzburg, Austria
Optimized Energy Concept:
2.000 m² collector field + 50 kWp PV
200 m³ storage tank
heat pump 160 kWth
Results
Specific solar yield: 400 kWh/m².a
Solar fraction: > 30%
Reduction of Primary energy demand and CO2- emissions: -80%
