Abstract

The implementation of energy efficiency measures and use of renewable energy sources in educational buildings can significantly contribute to reducing energy consumption, but also to CO2 emissions in the entire public sector. The paper shows the comparison of energy consumption indicators for 61 elementary school buildings which have previously been divided in 12 groups, according to the period of construction and size, based on the national typology called TABULA, as the first step of further study on how to use the renewable energy sources. The aim of this paper is to use the energy benchmarking process to select representative facilities which are suitable for applying renewable energy sources, for their further energy efficiency improvement. Indicators of annual specific electricity consumption and CO2 emissions per unit area [kWh/m2] and per user [kWh/user] were calculated. After that, from two groups (in which the highest electricity consumption and CO2 emissions are 68.37% and 74.53% of the total consumption/ emissions), one representative facility was selected.

克拉古耶瓦茨市教育建筑的能源基准——提高能源效率的可能性

在教育建筑中实施能源效率措施和使用可再生能源可以大大有助于减少能源消耗，但也可以减少整个公共部门的二氧化碳排放。本文对61所小学建筑的能耗指标进行了比较，这些建筑在国家TABULA类型的基础上，按照建造时期和规模划分为12组，作为进一步研究如何利用可再生能源的第一步。本文的目的是利用能源基准过程来选择适合应用可再生能源的代表性设施，以进一步提高能源效率。计算单位面积年比用电量[kWh/m2]、单位用户年比用电量[kWh/用户]、单位用户年比用电量[kWh/用户]等指标。然后，从两组(最高的用电量和二氧化碳排放量分别占总用电量/排放量的68.37%和74.53%)中选出一个具有代表性的设施。
