Technical-economical estimation of the renovated Lithuanian schools.

Lithuanian school buildings constructed before World War II or during the Soviet period have many defects. Most of these buildings have problems such as excessive energy use for heating, windows that are not airtight when closed, defects in the external walls, moisture damage, indoor microclimate parameters which do not correspond to the hygienic norms, etc. As the bulk of energy is consumed for the heating of buildings, this point seems to be the most important in respect of energy savings. Problems appearing in school buildings as well as the results of audits in 30 Lithuanian schools which were supposed to be renovated in the year 2001 are discussed in the article. The loan of 80 million litas was set for the renovation of the educational buildings among 52 municipalities at that time. The distribution of the renovation works in the schools is presented. The direct connection between heat energy savings and the amount of investments for heat saving implementation in the schools is estimated. [ABSTRACT FROM AUTHOR]
