An Innovative Application of 5GDHC: A Techno-Economic Assessment of Shallow Geothermal Systems Potential in Different European Climates

Energy, 2023
Energy consumption for thermal purposes represents the most impacting energy issue in the European building sector. In addition to space heating, space cooling is constantly growing, due also to climate change, which provokes extreme hot events in summer even in moderate climates.

Grid-Coupled Geothermal and Decentralised Heat Supply Systems in a Holistic Open-Source Simulation Model for 5GDHC Networks

Sustainability
In order to reach climate protection goals at national or international levels, new forms of combined heating and cooling networks with ultra-low network temperatures (5GDHC) are viable alternatives to conventional heating networks. This paper presents a simulation library for 5GDHC networks as sustainable shared energy systems, developed in the object-

Evaluating Waste Heat Potential for Fifth Generation District Heating and Cooling (5GDHC): Analysis Across 26 Building Types and Recovery Strategies

Processes
Efficient cooling and heat recovery systems are becoming increasingly critical in large-scale commercial and industrial facilities, especially with the rising demand for sustainable energy solutions. Traditional air-conditioning and refrigeration systems often dissipate significant amounts of waste heat, which remains underutilized.

GIS-Driven Methods for Scouting Sources of Waste Heat for Fifth-Generation District Heating and Cooling (5GDHC) Systems: Railway/Highway Tunnels

Processes
This paper explores the innovative application of Geographic Information Systems (GISs) to identify and utilize waste heat sources from railway and highway tunnels for fifth-generation district heating and cooling (5GDHC) systems. Increasing the number of prosumers—entities that produce and consume energy—within 5GDHC networks enhances their efficiency
