Summary
The main aspects of the project were in the year of 1998 to fulfil Energy Audit of preschool "VARPELIS" in Utena city, Republic of Lithuania; in the years of 1999-2001, according to results and proposals of Energy Audit analysis there was accomplished partial preschool's building renovation and full renovation of heating system; after building renovation in 2002 there was carried out an Energy Monitoring in order to measure and compare energy consumption, climate conditions before and after renovation of preschool's building. In summary the implemented projects has given an effect to satisfy Energy Audit recommendations by fostering and teaching kindergartners as well, as municipality administrative employees of rational and efficient energy use in public houses.
Recommendations of the projects could be identified as it may be of service to implement Energy Audit projects in public, industry or private buildings to ensure the energy efficiency, energy conservation and acceptable payback time of the projects.
The energy audit was financed from state budget. Renovation of the preschool's building financed from municipality budget and the energy monitoring was financed from state budget.
