2 2 Green Villages: The Program Program: Green Agricultural and Insular Villages: New Model for Growth Authority: Center for Renewable Energy Sources, Athens, Greece ( Funding: 50 mil. Targets: Using energy saving measures and renewable technologies, to achieve Zero Carbon Equilibrium or Zero Energy Equilibrium Long term: Pilot projects, with local characteristics, demonstrating the Sustainable Growth model WITH FUNDING FROM GREECE AND E.U.

3 3 Dipotamia : Zero Carbon Village Dipotamia: Small village, part of Nestorio municipality, in Kastoria region 456 inhabitants 230 domestic (active) and 5 public buildings Main activities: agriculture and livestock Regional activities: logging and fur industry Production of approx tn wood +15% residues, annually Tourism activities: hunting tourism in Grammos mountains, River Party in Nestorio

8 8 Dipotamia : Energy figure Houses are the largest energy consumer Biomass is the main energy source of domestic heating (2/3 of total). Inhabitants purchase the necessary wood supplies in discount price from the local timber association. Wood is usually burned in stoves, with less than 50% efficiency Oil and electricity consumption and private transportation is the main CO2 emissions source 14% Energy comsumption 9% 5% 2% 1% 69% Public Buildings Infrastructure Street lighting Domestic sector Commercial buildings Public vehicles Private vehicles

9 9 Dipotamia : Action Plan Energy Saving Improvements in building s envelope in 183 domestic buildings and 5 public buildings Installation of 118 LED lights, replacing 125W HQI. Installation of energy efficient pumps for potable water supply. Purchase of one 1,5 tn, 7kW electric garbage truck Energy Production Centralized energy unit: Installation of a 3,5 MW, hot water biomass boiler. Development of a district heating network Installation of a 0,6 MW ORC cogeneration plant Electricity is supplied to the distribution network with feed-in tariff Heating bills are collected via water supply authority Total budget: 8 mil.
