Abstract

The aim of this work was to estimate the effectiveness of the renovation work that was carried out in 63 Lithuanian schools by disclosing the main renovation works, analysing changes in the amount of the energy used for the heating after renovation. Reduction of the windows area with shields, replacement of old doors and windows with the new ones were the most frequent renovation works in the tested schools. 52 % of respondents indicated condensation on windows after the renovation work. The indoor temperature of the schools increased from 15 °C to 18 °C. Also, the energy consumptions for the heating of the schools was lowered by 17 % in schools with district heating system and by 22 % in schools with local boiler house.
