Multi-perspective Methodology to Assess the Transition to 4th Generation District Heating Systems

Currently the transition towards 4th generation district heating (4GDH) systems is widely studied, but little research is done to give multi-perspective methodology for the assessment of the transition to 4GDH systems. Thus the aim of this study is to provide multi-perspective methodology that can be used to assess the conversion from a conventional district heating (DH) system to the 4GDH system. This methodology combines empirical study, system dynamics and multi-criteria decision making analysis, economic and policy analysis. This methodology allows evaluating various DH development scenarios from the point of view of all involved parties and can be used to elaborate and compare several potential DH development scenarios, thus evaluating the potential of each scenario toward 4GDH system. Practical applicability of this methodology can found both in scientific and policy makers' community.
