Hotspots in Zadar


Salutation to the Sun

Excursion Country Module “The Balkans” - MSc “Renewable Energy in CEE”

Friday, May 06, 2016 - We start this day with sunny 15 degrees Celsius at 8:30 am (Croatian time not Swiss time :-)) and go to the biogas plant in Gradec. On the way the bus driver tells us that he has to make a break by law after four hours driving. As the bus is metering automatically, we have no chance to bypass this rule. So we have a very short stop at the biogas plant, but the more intensive (especially more intensive in smelling). The biogas plant is run by “Agrokor Energija”. The company fosters an ecological approach to the utilization of by-products generated in agricultural production, processing industry, food industry, storage management and retail and wholesale business, following the strictest environmental standards. Beside the plant there is a pig farm, and the biogene waste of the farm will be treated at the plant.

We go on with a delay of 15 minutes. After the announced forced break at a motorway service area we rush to the coast, to Zadar. At the City Hall we are warmly welcomed  by The Vice mayor of the City of Zadar, Ivica Vlakic. Ana Bajlo, head of the section for energy efficiency at the Department for spatial planning and construction, provides us with a good overview of the current EE project in the City of Zadar. Afterwards Ive Suric, project manager at the development agency Zadra Nova, accompanies us to the water front of Zadar to show us “Salutation to the sun” and the “Sea Organ”.

Both, Salutation to the Sun and Sea Organ are hotspots to tourists as well as to the locals – and to us. The "Sea Organ" is an architectural object and an experimental musical instrument (conceived by architect Nikola Bašić), which plays music by way of sea waves and tubes located underneath a set of large marble steps. On its surface, the organ looks like large marble steps leading into the Adriatic Sea. Below, however, lies a series of narrow channels that connect to 35 organ pipes. Each set of steps holds five organ pipes each and is tuned to a different musical chord. As waves and wind push air through the channels, a song pours through the organ pipes and out onto the steps above.

The “Salutation to the sun” is a 22 metre diameter solar panel formed from 300 multi-layered glass panels. Underneath these glass conduction plates, there are a series of solar cells. The solar cells absorb the sun’s energy from sunrise to sunset, and convert this energy into electricity. The electricity produced is then used to light the entire waterfront at night – a unique example of an efficient and renewable energy source. At sunset, the installation switches on and displays a series of bright colourful lights. The motion of the lights is dependent on the solar energy collected throughout the day as well as the power of the waves, and is supposed to also represent the motion of the solar system. All eight planets are represented by proportionally sized solar lights placed at their proportional distances from the sun.

After a short break – some of us use the time and roll up their trousers to plash in the Adriatic Sea – we go to Udbine. We visit the solid biomass cogeneration plant “Lika Energo Eko” with the pellet production before we return to Zagreb. It was a long and exciting excursion day.
