Evidence of success

The project resulted in the installation of 2 boilers with a total of 0.6 MW using renewable energy source and the change of 423 lamps with energy efficient ones. These installations will lead to:
• Reducing the annual CO2 emissions by 94.60 t. and improving air quality.
• Annual energy savings amount to 224.121 MWh/a
• Annual cost savings of 9,690 EUR
• Moreover, all the energy necessary for heating of this building is from renewable energy source available in the region.

Potential for learning or transfer

It is important to have a preliminary market assessment and selection of technical solutions to be included in the project design in order to reach the best results of the implementation of the energy efficiency measures. The selection of offers based on cost benefits, not on lower price are an additional guarantee for the success of the project. Such approach to the procurement process requires qualified experts that can provide the best solutions
