Summary
About 45 % of total final energy consumption is used in housing sector. Whereas more than 60 % of the Lithuanian population resides in multi-apartment buildings constructed during 1961-1990, which are not complied with the effective requirements, this sector has great energy saving potential.
The main aim of this study is to evaluate the energy saving potential in residential buildings in Kaunas city. The results of this study are included in "The Plan of Rational Energy Use in Kaunas City", which is prepared for Kaunas City Municipality and SC "Kaunas Energy" - the main central heat supplier in Kaunas city. The biggest heat consuming group of SC "Kaunas energy" is residential customers (about 70 %). The results of potential assessment can be very useful in planning and optimizing municipal energy plans and renovation programmes, identification of available energy efficiency means and can be used for heat demand prognosis for DH companies.
Results
The calculations were made taking into account that 1 % per year of the total five and nine storied residential buildings will be renovated till 2007, during 2007-2009 period the number of the renovated buildings will increase up to 3 % per year. The heat consumption reduces about 50 % after the five-storey residential building renovation and about 40 % after the renovation of nine-storey one. According to these prognoses the 113 fivestoried and 55 nine-storied buildings would be renovated and in 2010 the heat energy consumption in them would be decreased by 29 115 MWh or 7, 7 % of the consumption in 2004. The total possible heat energy saving potential in all five and nine-storied residential buildings is 266 258 MWh. The total possible heat energy saving potential in "housing sector" in Kaunas city is 437 241 MWh. The pollution of carbon dioxide would be decreased by 83 950 tons per year.
