About Store4HUC

Welcome to the second edition of the Store4HUC Newsletter. The European project Store4HUC develops solutions for renewable energy sources and their storage in historical city centers. Due to strict regulations to protect historical buildings, it is difficult to supply and store renewable energy in listed monuments. Store4HUC addresses this challenge by providing solutions for adaptation of low-carbon energy supply and storage in historical urban centers and providing tailor-made tools to assess both the impact of energy storage and energy independence. The project pilots its tools in 4 historical urban buildings in Croatia, Italy, Slovenia and Austria.

Integration of a Thermal Storage for the Parish Church in Weiz, Austria

Within the project a thermal storage will be implemented in the parish church of Weizberg. The parish church is located on a hill in the historic area of Weiz.

The history of the parish church goes back to the 11th century, when the church on the "Himmelberg" was popular for pilgrims. Thanks to the engagement of the region and municipalities, there is a lot of experience available with renewable energies due to previous projects that provide a positive atmosphere to implement the Pilot.

Store4HUC activities focus on the integration of a thermal storage for the church on Weizberg, which is connected to the public district heating grid. Details on the how the thermal storage will be integrated can be found on our website.

Feasibility Studies for Store4HUC

In the course of the Store4HUC project, a feasibility study is being carried out for every piloting activity:

  • for integrating a water buffer tank in the existing heating structure of the historical church in Weiz, Austria;
  • for the energetic optimization of an already existing slope elevator in Cuneo, Italy;
  • for installing a photovoltaic system with energy storage in a traditional castle in Bracak, Croatia
  • and for the paraffin-based latent storage attached to a geothermal heating system in Lendava, Slovenia.

Three of the feasibility studies were published in the last months and are available to download on our website.

Preview of the Autarky Rate Tool

New Electricity Storage Evaluation Tool in the Pipeline

In course of our project, the so-called Autarky Rate Tool will be developed. This very useful simple online tool is soon available for everyone who considers installing electrical storage solutions in combination with renewable energy sources.

With only a few numbers, the user can get an evaluation of the technical, economical and ecological effects of the chosen renewable energy storage system configuration. The European project Store4HUC develops solutions for renewable energy sources and their storage in historical city centers. Due to strict regulations to protect historical buildings, it is difficult to supply and store renewable energy in listed monuments.

First Scientific Publications in Store4HUC

The Austrian team of STORE4HUC was invited for poster and parallel session presentations on two international conferences.

The team exhibited a Poster at The 3rd Conference on Smart and Sustainable Planning for Cities and Regions – SSPCR 2019 in Bolzano and held a presentation at “Greening the Strategies” of the 6th Central European Biomass Conference (CEBC) in January 2020. Both events focused on solutions and strategies to serve as a realistic exit from fossil fuels.
