The paper critically analyzes the process of realization of energy efficient kindergartens in the City of Belgrade whose designs are obtained in the open public urban architectural competition. The process initiated, financed and realized by the city government of the City of Belgrade is an example of an effort toward meeting the EU directives and achieving the Energy Community objectives in the field of energy efficiency and usage of renewable energy sources, where facilities for public use must lead and be examples of the best practice. The whole process is analyzed, starting from planned conditionality of urban-architectural competition announcement through special conditions concerning energy efficiency and usage of renewable energy sources to construction and use of zero energy kindergartens, with a special analysis of the energy efficiency parameters of one of the kindergartens chosen as a representative of a good practice of competition solutions implementation of energy efficient facilities for the public use.

Increasing energy costs, the change from conventional to renewable energy sources and the growing awareness of green production, especially in Germany, are crucial challenges for society and for industry. Renewable energy sources, especially solar and wind power, lead to a limited and volatile energy supply. Therefore, energy is no longer a resource which is available and ready on demand in the future. This change in energy supply hugely influences the production and industrial processes and is leading to alternative forms of production. There are high potentials in terms of energy efficiency and energy flexibility to master the described challenges. This paper presents an overview of the current state of the art in energy efficient and, especially, energy flexible production. The focus is on new aspects caused by the changes in production processes. Furthermore, research action fields concerning the energy flexibility of production machines are shown and explained through a practical example.

The article is devoted to the issues of the functioning and development of energy in each country, caused mainly by the economic expediency of renewable energy and the requirements of energy independence. Also, the article examines the importance of replacing traditional fuels with alternative energy sources. The international experience of the countries in the field of efficient use of available natural resources of the fuel and energy complex and enhancement of the potential of the energy sector have been analyzed. A number of common characteristics and directions of energy efficiency improvement for European countries are highlighted. Alternative types of energy and measures necessary for their implementation have been offered. The potential resources of renewable energy sources have been analyzed. The article is devoted to the use of economical and ecological type of fuel - biofuel for Ukraine. On the basis of the analysis of the situation on the energy market, renewable energy is examine, which plays a compensatory role in global energy consumption in the conditions of growing exhaustion of non-renewable sources.

AbstractThe energy efficiency – indoor air quality dilemma is well known and the main drawback to operate the mechanical ventilation is electricity costs as concluded from previous studies. Educational buildings are one of the places where future taxpayers spend a lot of time. This paper aims to study an alternative solution on how to reduce energy efficiency – indoor air quality dilemma in educational buildings by adopting systems that use renewable energy sources. A typical education building in Latvia is taken as a case study by changing it from a consumer to prosumer. This building type has a specific electricity usage profile that makes the choice of photovoltaics (PV) power quite challenging so the various power options have been analysed and used for an electricity solution. Also, the more decentralised preference is chosen – disconnect from a public heating provider and using a local system with a pellet boiler. Educational buildings using PV can reduce the electricity tariff, but the payback periods are still not very satisfactory without subsidies. The average electricity tariff per month varies between scenarios and the best one is for the scenario with 30 kW installed power. The educational building partly using 16 kW PV system reduces not only its bill for electricity but also reduces CO2 emissions by around 36 tons. The education buildings as energy prosumers using renewable energy sources are reducing GHG emissions by having high indoor air quality.

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.
