Abstract

Abstract

En 中文
• Substantial listing of technical requirements for 5GDHC in existing building stock. • Simulation-based performance assessment of air-source 5GDHC at varied line densities. • Additional variation of district properties and PV installation in 5GDHC networks. • 5GDHC networks outperform 4GDH networks regarding energy consumption. • 5GDHC networks can show economic benefits over 4GDH networks at low line densities.
