Zlín, Czech Republic

Zlín is a largely industrial city with a population of around 76,000 inhabitants. Its suburb, Louky, with around 1,600 inhabitants, is the principal focus area of CONCERTO measures. 92 m² area of solar thermal systems for combined heating and Domestic Hot Water (DHW) for 20 single-family houses and 268 m² large-scale applications for multi-family houses, or communal baths, represents an increase in the use of energy from RES. This is complemented by 7 photovoltaic (PV) systems in private family houses (5 kWp each) and three large-scale PV systems (40, 200 and 470 kWp).


The CONCERTO approach

New strategies in district heating, lower return temperatures.
New materials and technologies for new eco-buildings and retrofitting.


Use of Renewable Energy Sources

•    Solar thermal systems
•    Photovoltaic
•    Biomass
•    Re-processing the biodegradable wastes into a certified combustible compost with the heating value of ca 3,2 kWh/kg


Low Carbon Technologies

•    Insulation
•    District heating
•    Optimized lighting


Highlights

The eco-village Jizni Chlum near Zlín consists of earth-sheltered houses. Their energy consumption is close to those of passive houses. 60 - 90% of the heat is provided from renewable sources. The building is covered with earth. Only the front façade is visible. The rear is built into the slope of a hill. This, together with good insulation, results in low heat losses through the building envelope.

A new technology was installed at Zlin’s central waste depot enabling the re-processing of biodegradable wastes into a certified combustible (”energic”) compost. This technology, together with the large-scale PV system of approximately 200 kWp located at the communal waste depot, will be used as a “demo-park” presenting utilization of various kinds of renewable energies.
