Up to 80% of total energy consumption in the EU is attributed to urban areas, mostly with historical urban centres. At the same time, low carbon energy supplies in the style of energy storages, especially in historical urban centres, is a rarity in central Europe. This is mainly because of strict architectural protection constraints, higher implementation costs and often also conflicts with town planning policies.
The STORE4HUC project aims to improve territorially based low-carbon energy planning strategies. It will enrich policies that support climate change mitigation in historical city centres by focusing on improved urban and spatial planning for integrating energy storage systems to enhance the public institutional and utility capabilities.
The partners will develop policy recommendations and identify suitable integrated technological solutions to overcome low carbon development barriers in historic centres. They will also facilitate the development of open energy and load management systems for energy efficiency and use of renewables. With its concepts and pilot systems, STORE4HUC will provide smart city test beds, where technicalities will be reconciled with historical and architectural values.
For those working in the sector of energy efficiency, we present the Optimal sizing calculator!
It is an in-depth Tool for the advanced users like energy experts and others working in that field. Optimal parameterisation of photovaltaic and battery energy storage systems are supporting the customers to save costs and be more environmental friendly at the same time!
The Autarky rate tool is a simple but very useful online tool which is available for everyone who is interested in the installation of electrical storage solutions in combination with renewable energy sources.
The investment specification document (pre-investment concept) covers all the aspects to be evaluated before starting with investing and procurement procedure, incorporating features already included in preliminary project design steps and energy audit where available.
We conducted qualitative interviews with a group of experts are about the lessons learned during the planning phase of the pilots. These are based on inquiries designed in close cooperation with the partners of the four Store4HUC pilots including particular background information for the interviewees. What we learned is now summarised in a full report: Read the full article by clicking here!

15. 10. 2019
Old and modern in symbiosis? Why not! It is a practice that has been nurtured in Western European countries for years, now Croatia catches up with its numerous prestigious cultural sites. With the goal of extending the life of these buildings and enhancing the sustainability of cultural objects, our Croatian partners held the project launch event in Bračak Energy Center on 16th of September.
Obnovljivi izvori energije i objekti pod kulturnom zaštitom?! Naravno, zašto ne?! Još jedan novi #EU projekt #Store4HUC koji za cilj ima i postavljanje fotonaponskog sustava na Energetski centar Bračak, baterije za skladištenje energije te unapređenja postojećeg sustava upravljanja zgradom. #regea #energytransition
Glavni cilj projekta Store4HUC je unaprijediti i obogatiti strategije energetskog i prostornog planiranja koje su usmjerene na povijesne gradske jezgre usredotočujući se na integraciju sustava za pohranu energije u njih. U projektu ukupne vrijednosti 1.726.608,70 eura FER će razviti programske alate za planiranje optimalnog rada sustava pohrane energije u okruženju povijesnih gradskih jezgri pri čemu se poštuju specifična ograničenja takvih zaštićenih sredina.
Das neue europäische Projekt Store4HUC entwickelt Lösungen für erneuerbare Energien und ihre Speicherung in denkmalgeschützten Gebäuden.
„Denkmalgeschützte Häuser mit erneuerbaren Energien zu versorgen und diese zu speichern ist oft schwierig: Sichtbare Veränderungen am Gebäude sind nicht möglich und Einbauten oft schwierig. Dafür sind fantasievolle Lösungen gefragt“, so Dr. Wolfgang Hofstetter vom Klima-Bündnis.

“It is not always easy to supply listed buildings with renewable energy and to store that energy: visible changes to the building are not possible and the subsequent installation inside the buildings is often difficult. This calls for imaginative solutions,” explains Dr. Wolfgang Hofstetter of Climate Alliance.
Measuring the degree of self-sufficiency with just a few clicks and evaluating the technical, economic and ecological effects of the chosen system configuration – this is now provided by the so-called Autarky Rate Tool. The tool is suitable for all those who are interested in installing electric storage systems in combination with renewable energy sources. The aim is to motivate users to take a closer look at the topic and subsequently contribute to an increased and intelligent use of electric storage solutions. Another important aspect of the tool is the checklist, which summarises the results in a pdf document. This document also contains an analysis of the calculation results as well as specific information on the use of storage in historic old towns.
To maximize the contributions while minimizing the price of the installations, the Optimal Sizing Calculator computes the optimal sizes of a Photovoltaic (PV) and a battery energy storage system (BESS) for a site. Those sizes are peak power of the PV system, energy capacity of the BESS, and power converter rated power of the BESS. The calculator uses typical yearly consumption profiles of a variety of consumers, but if you have your own consumption profile recorded you can use it to calculate your optimal parameters more accurately.
Please follow the instructions in the README text document and the User Manual in the zip folder carefully before working with the calculator.
If you have problems with the tool, feel free to contact us:

The Work Package Management consists in the whole project life cycle. It's composed by 4 different activities and it will produce the usual deliverables required by EU funded projects. WPM is under the responsibility of the Lead Partner (LP) project coordinator that will supervise 1 Project Manager, 1 Financial Manager and 1 Communication manager.
WPT1 aims to establish the deployment desks (a group of stakeholders) in each region enabling to engage various stakeholders (local decision-makers, representatives of municipalities, infrastructure providers, sectoral agencies, independent energy experts, etc.) in the process of energy storage piloting and planning.
WPT2 is dedicated to pilot action implementation and mutual learning activities. Firstly, the urban key performance indicator will be established, followed by Investment specification for each pilot sites will be performed. The latter enables to specify the
technical specification, define installation pilot process and conceptualizing the pilot.
In WPT3 the objective is to present the impact of integration of energy storage systems in historical urban centres. Based on the technical & legal framework of integrating efficient energy storage systems in HUC, affordable solutions will be used to demonstrate the matured combination of renewable energy sources & energy storages.
The recently renovated Bračak Manor is already equipped with various energy saving tools. The already existing systems will be combined with the new ones through an advanced energy management ICT system that can be built on top of the already existing central monitoring system as a coordination service that optimally exploits different available assets.
In 2009 the city of Cuneo has realized a Public Sloping Elevator. In 2017 the sloping elevator has carried out more than 150.000 rides, with an increase in use of 5% compared to th previous year. The mobility connection service of the sloping elevator could be improved thanks to an energy efficienc refurbishment. The pilot project aims to realize a new energy storage system linked to a PV plant, replacing some inefficient plant components.
The infrastructure provider Lendava Petrol Geoterm built a heating system with geothermal
energy. The library building of Lendava is a neo-baroque villa from 1906 and is still heated by fossil fuel. The Library produces 16,8 tons of CO2 related to space heating annually. The connection to the existing geothermal network woul reduce this amount to zero.
The main objective of the WPC is dissemination of the project results to a wider audience and to engage additional stakeholders that are keen on the project topic. The digital activities, considered to be the modern tool for connecting to the target group, will play a crucial role. Specific events will be organized, e.g. tool trainings, webinars and kick-off events in every HUC. The project results will be also promoted through presence at relevant thematic cross-fertilization events.
As the STORE4HUC proceeds, you will find valuable resources in the section in various format.
