VIA University College invites applications for a fully funded PhD position focused on modelling and optimisation of shallow geothermal district heating and cooling networks (5GDHC). These systems combine ground-source heat exchange with distributed heat pumps. The project will address current gaps in system design tools by developing a Mixed Integer Linear Programming (MILP) framework and improving demand and supply-side modelling.

The PhD student’s primary workplace will be VIA University College’s Campus in Horsens, Denmark, at the Research Centre for Built Environment, Climate and Water Technology. 

Main Tasks

• Develop a MILP optimisation module for the Pythermonet tool.
• Incorporate life-cycle costs, emissions, and exergy considerations into the optimisation.
• Process operational data from Danish thermonet systems for validation purposes.
• Use Modelica simulations to evaluate optimisation results.
• Generate building-level heating and cooling load predictions using Energy+ with BBR and climate data.
• Map and model waste heat sources relevant for thermonet regeneration.
• Apply the developed framework in Danish case studies.

Expected Outcomes

The project is expected to result in several scientific publications related to waste heat mapping, building demand modelling, MILP optimisation, and case studies of Danish systems.

Qualifications Required:

• Master’s degree in geology, or a similar field.
• Programming experience (Python).
• Basic knowledge of optimisation methods (e.g., MILP).
• Ability to work with data processing tasks.

Preferred:

• Experience with Modelica, Energy+, or other energy modelling tools.
• Familiarity with GIS software such as QGIS.
• Understanding of thermal energy systems or district heating.

What We Offer

• A fully funded PhD position.
• Access to relevant datasets, tools, and supervision.
• Collaboration with researchers working on geothermal heating and cooling.
