• An associate in the project that initiated the idea: • EXtension of POtentiality of Adriatic UNESCO Sites

• EX.PO AUS intends to conceive and experiment an innovative and very articulated long term strategy aimed at managing and valorizing the UNESCO sites of the Adriatic sea, trying to address new ideas, tools and actions to manage in a good manner these sites and achieve a sustainable economic valorization of them, moreover from the ecological and energy efficiency point of view.

Sustainable energy and fortified heritage

EXtension of POtentiality of Adriatic UNESCO Sites

• GUIDING THOUGHT: UNESCO sites is an important indicator of the strong effort made by the local communities to preserve historical, artistic or natural heritage of great value, but, at the same time, this trend must stimulate them to consider the UNESCO acknowledgment as a starting point, because this acknowledgment doesn’t mean to “embalm” a place, but to promote in it a complex and pro-active strategy of preservation & economic valorization, which should involve a plurality of public & private actors.

Proposal of pilot project: Advanced Solar Energies Applied to Fortified Heritage

• Advanced technologies:

Photovoltaic roof tiles

• PV Roof-tile represents the last frontier of integrated photovoltaic

• cells are hidden into a layer that faithfully reproduces the surface of a common roof-tile.

• No visible difference between normal and PV roof-tile• Dyaqua Art Studio 

Photovoltaic roof tiles

Photovoltaic roof tiles

• Location: Dubrovnik Natural History Museum• Produced electric current will be used for their own

needs• Power: 23 kW• CO2 emission reduction: 12,2t

• Annual savings: 4 500 €

Boskovic Square – version 4

Boskovic Square – version 4• 12 500 kWh anually / 4,9 t CO2

• Center of the plant is as kind of a monument. • Promotes the use of UNESCO World Heritage Sites as

field observatories on the sustainable use of renewable energy sources.

Boskovic Square – version 4

We hope that this powerplant will become a symbol of a great past of Dubrovnik and UNESCO and

bright future
