Improving the efficiency of using heat in preschool buildings: Case study of 'Ciciban' kindergarten

Abstract

Educational buildings have a significant share in the total number of buildings of public sector. Also, significant part of energy consumption belongs to these buildings. There are 15 kindergartens that are under 2 preschool institutions. Their specific annual heat consumptions are from 79.42 kWh/m2 to 491.52 kWh/m2 (from 106.02 kWh/m2 to 325 kWh/m2 for objects connected to the district heating system). The average specific annual heat consumption is about 22% more than the consumption in neighboring countries. Most kindergarten buildings were built in the '70 and '80s of the last century and do not have adequate thermal insulation. Based on the defined methodology, specific annual heat consumption of these buildings has been analyzed, priorities for reconstruction have been defined and measures for improvement of energy efficiency have been proposed. Conducted case study of implementing the proposed measures at 'Ciciban' kindergarten showed that savings could be from 36% to 58% in heat consumption.
