Energy Benchmarking

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.

Electricity consumption is constantly growing in the world. In this connection, there are new urgent problems of increasing energy efficiency and energy conservation. Exactly, the economic development of countries and the change in the citizens’ life quality depends on successful solutions in this sphere. In addition, energy efficiency today is the most important developmental indicator of the national economy. The article discusses electricity consumption statistics in the world, a comparative analysis of the statutory conditions and the main implementing energy efficiency methods and programs in different countries.

The analysis conducted in this paper was initiated by the fact that Serbia emitted around 80 million tons of CO2, equivalent in 1990, and in between 85-89 million tons in 2010, which places it among ten countries with the highest emission of CO2 per capita in the world (data by Cener for Ecology and Sustainable Development, Subotica, Serbia). This paper is aimed at making a correlation between the improvement of thermal performance of structural elements of buildings in order to enhance their energy efficiency, which is also economically justified, and reduction of GHG (CO2) emission whose economic benefits are not so easy to assess even though it represents an environmental problem. The case study analysis, presented by this paper, using the example of a select number of kindergartens in the territory of the city of Nis, Serbia, is aimed at determining the correlation of the effects of improvement of their energy performances on the reduction of GHG emission reduction by quantifying the benefits of CO2 emission reduction as a result of energy efficiency improvement reflected through the increase of energy class. The specific review conducted in this paper indicates the environmental importance of improvement of energy efficiency by valorizing the quantitative reduction of CO2 emission as a benefit of implementation of energy revitalization of buildings.
