Thermal analysis reveals that the DTR maintains an average surface temperature of 8.11 K below ambient in hot conditions. This cooling effect is suppressed in cold conditions to insulate the heat. As a result, the proposed DTR can save more than 18 kWh·m<sup>−2</sup>·year<sup>−1</sup>·in the world's major cities.

This paper introduces a novel heat pricing model in combination with an operation strategy that addresses all key aspects of operating these networks by implementing a merit-order bid price system based on levelized costs of heat, with caps and floors. In addition, it provides an analysis of these structures by applying the operational strategy and the novel pricing model to a case study. The results demonstrate that a supra-regional district heating network can be economically and technically integrated into the examined area without any limitations in temperature levels.

The findings revealed that brand is the paramount consideration for residents purchasing ACs, with the majority willing-to-pay up to 10 % more for a relatively energy-efficient AC. Regarding AC usage, variations in temperature settings and operation duration led to considerable disparities in energy-saving effects across regions. Specifically, the trade-in of each grade 1 AC in the southeastern region was estimated to achieve an annual electricity saving of 43.5 kWh, compared to 11.5 kWh in the northeastern region.
