Several cities are currently developing strategies in order to lower the emissions of their building heat supply to zero. Nevertheless, up to now there is no heat transformation guideline addressing questions such as the steps required to develop a transformation strategy and their order, the maturity levels of transformation strategies, or existing transformation measures and a viable methodology to compare these. In this research, based on scientific findings of optimal system design, connected with the practical experience of relevant stakeholders, who are involved in the transformation process, these questions are addressed focusing on district heating.

The developed overview matrix for district heating transformation measures, arranging these in the criteria transformation target and point of effect, has been shown to facilitate the discussion of transformation measures. Prioritizing the measures should be based on a utility analysis, in which the results are depicted in an adapted Eisenhower matrix. The developed transformation strategy guideline and maturity definitions helped to assess the next required steps to further develop the strategy. Currently most district heating operators are still in a low transformation strategy maturity (step 2 out of 5).

一些城市目前正在制定战略，以将其建筑供热的排放量降至零。然而，到目前为止，还没有热转化指南解决诸如制定转化策略所需的步骤及其顺序、转化策略的成熟度或现有转化措施以及比较这些的可行方法等问题。在本研究中，基于优化系统设计的科学发现，结合参与转型过程的相关利益相关者的实践经验，这些问题将重点解决区域供热问题。

已开发的区域供热改造措施概览矩阵将这些安排在标准改造目标和效果点中，已被证明有助于对改造措施的讨论。衡量措施的优先顺序应基于效用分析，其中的结果在经过调整的艾森豪威尔矩阵中描述。制定的转型战略指南和成熟度定义有助于评估进一步制定战略所需的后续步骤。目前，大多数区域供热运营商仍处于转型战略成熟度较低的阶段（第 2 步，共 5 步）。
