The Cheap-GHSP geothermal facility at the Technical museum Nikola Tesla was officially opened on 20 June 2018 in Zagreb, Croatia. In attendance were the Ministry of Culture of Croatia, the Croatian National Commission for UNESCO, the municipality of Zagreb, museum management authorities, and partners from Cheap-GSHPs project. The purpose of the facility is twofold, to serve as a showcase for visitors of the museum and to provide a supply of sustainable energy for the cooling and heating of the museum’s exposition room.

After 3 years of interdisciplinary work, Cheap-GSHPs has reached one of its main milestones. The work done is a tangible contribution to the implementation of the UNESCO Recommendation concerning the protection and promotion of museums and collections, their diversity and their role in society (2015), proving how museum can become places for sustainability by applying innovative sustainable energy technologies, in everyday life.

Zagreb, with its Technical Museum, is one of the 6-real demonstrators of Cheap-GSHPs in Europe, in different grounds and under diverse climate conditions, with the aim of developing more efficient, more affordable and safer shallow geothermal systems. This is a tangible advancement in making geothermal power solution more diffuse and hopefully capable of contributing to the reduction of atmospheric CO2 emissions and achieving the sustainable energy goals of the United Nations and European Union, along with the provisions of the Paris Agreement on Climate Change.

UNESCO’s role in the Cheap-GHSP project is highly relevant due to its specific interdisciplinary activity aimed at accommodating geothermal innovative solutions in cultural heritage sites and buildings, with the objective of combining different stances, such as innovation in sustainable energy, conservation of built heritage, climate change mitigation, and energy poverty reduction.

During the opening, the geothermal system successfully switched to cooling functionalities. The infield team operated a second successful supervision on the geothermal system checking the main functionalities and the winter/summer modality changeover. The system managed to lower the internal temperature of the exposition room from 28°C to 19°C, turning a hot and humid environment into a pleasant one for both visitors and workers.

The training for the handover of the geothermal system was completed and instructions were given to museum management on how to correctly handle the basic functionalities and commands. The data stored in specific sensors, indoor and outdoor, for a constant environmental monitoring were downloaded to be further elaborated and analysed. These data sets are useful to assess the geothermal installation performance according to different climatic parameters and changing seasonal patterns.  

All the attending authorities were extremely satisfied with the architectural features of the technical room in the renewed yard of the museum and with the performance of the innovative heat pumps. The system now performs as a permanent showcase for Education for Sustainable Development on sustainable energy and climate change mitigation actions. 

The expected impact of the Cheap-GSHPs installation is:

  • Curbing costs of shallow geothermal power installation by 20-30% through the deployment of an innovative drilling technology and machinery.
  • Demonstrating the compatibility of such innovative systems with the preservation of the architectural integrity of selected real and virtual cases in cultural buildings of high symbolic value for further dissemination and replication in cultural buildings.
  • Increased capacity and awareness of the general public and specialists about potentialities inherent to geothermal power application also in a context of cultural buildings for a more comprehensive strategy in CO2 emissions reduction and climate change mitigation policies.
  •  Providing fundamental supply of energy for the cooling and heating of one of its major facilities, the exposition room, which is now a much more comfortable environment both for workers and for visitors.

The Museum displays Cheap-GSHPs solution as one of the possible technical contributions to green energy, becoming a component of educational and informative activities conducted by the museum in the section devoted to renewable energy and energy efficiency.
