The LowEx approach for communities
Application of LowEx approach for optimization of community demand adapted supply. The very efficient so called low exergy supply and use are of particular interest (see green boxes).
Scope
Improvement of energy conversion chains on a community level
•Significant reduction of energy demand and GHG-emissions
•Integration of renewable heat and cold sources
Objectives
• The focus is on technologies and innovative concepts using low valued energy sources (LowEx) and renewable energies for the heating and cooling of neighborhoods and cities.
• The objective is to demonstrate the potential of low exergy thinking on a community level as energy and cost efficient solution in achieving 100% renewable and GHG emission-free energy systems.
This includes:
•Storage concepts
•Networks / grids
•Control systems und strategies
•Business concepts

Expected outcome
• Design guidelines for optimised low exergy systems on community scale
• Technology solutions and new development approaches for smart distribution solutions
• Case study evaluation and best-practice catalogue
• Exergy evaluation on community scale
Our target groups:
•Energy supply and technology industry,
•Project developer and housing companies,
•Decision makers within communities,
•Academia, research and education
