Task 3 : Sustainability and urban planning

 

 

This task is to address the sustainability of thermoactive geostructures in the long term.

The risk of “local” thermal interaction with neighbouring geothermal plants needs to be treated. That allows the extension to city scale, which is necessary for an intelligent and rational city planning. The challenge is to assess the number of thermoactive geostructures systems that can be installed at the city scale without reducing the ground thermal capacity and what will be their contribution to satisfying the energy demands of city buildings and infrastructure.

 

By sharing available data and experiences across Europe, the COST Action will allow to assess long term behaviour of thermoactive geostructures including their lifetime, the variation of groundwater temperature and the potential heave and settlements imposed on the overlying structures.

 

The socio-economic impact of thermoactive geostructure installations will also influence the development of large urban areas and the need will arise for a more rational urban planning and large scale environmental impact assessment. The energy needs of a complete urban zone will be considered. For example, tunnels could provide energy to many buildings located above, which requires to consider both technical, managerial and financial problems.

Rationalization and planning in large cities is becoming more and more necessary, considering the potential interferences being created by different thermoactive geostructures operating in adjacent areas. Guidelines to help in better locating the thermoactive geostructures are required. Integrating the emerging needs and exploiting new opportunities can allow to maximise benefits for the communities of future smart cities.
