Typical methods of improving energy efficiency of buildings to the nZEB standard, such as better external envelope insulation, using better windows, or introducing a proper ventilation system, may prove inadequate. Often, it is necessary to apply unconventional systems and renewable energy sources. Each case has to be analyzed considering the location, building technology, usage of the building, and even conservation officer's requirements. To verify the effectiveness of standard activities in various climates, the following locations in Europe were chosen: Athens, Stockholm, and Warsaw. For evaluation, two methods were applied: the monthly balance method and the simplified hourly method 5R1C.

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.

Energy Efficient Building

Croatian energy strategy defines ambitious goals aimed at achieving energy transition toward a sustainable low-carbon society. Achieving those goals requires significant investments in the renewable energy sources and improved energy efficiency of buildings. The purpose of this paper is to estimate and compare the economic effects of the energy transition on the renewable energy supply and demand side. The estimation of the energy transition effects in Croatia in the period 2020–2050 is based on the input-output model, which identifies direct, indirect and induced effects of investments in renewable energy sources and energy efficient buildings renovation. Results of the study reveal relatively higher gross value added and employment effects induced by investments in building retrofits, but the effects of investments in renewable energy are also significant. Investments in sustainable, efficient and environmentally effective energy system could significantly contribute to Croatian GDP. While GVA effects range from 0.4% to 0.6% of annual GDP, the share of full-time equivalent jobs induced by energy transition could reach 0.5% to 1% of total employment in Croatia. Investments in RES plants and energy efficient building reconstruction are not substitutes but complements which ensure a smooth energy transition if undertaken together.

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.

The paper analyzes the potential of renewable energy sources within the area of City of Belgrade, and explores the possibilities of their further implementation in the field of renewable energy sources and energy efficiency, in line with mandatory EU Directives. A synergetic approach has been proposed in the recommendations for the implementation of goals/targets and policies in the fields of renewable energy sources and energy efficiency in the City of Belgrade. They put an emphasis on the importance of implementation of the strategic documents of the City. Recommendations on have been provided regarding the required institutional preconditions that have to be met in order for these goals to be achieved, as well as urbanistic and building design-related measures/standards in achieving energy efficiency.
