Foam polystyrol has been part of our lives for more than 70 years. The specific characteristic of the foam PS is light weight - 10-40 kg / m³, compared to 800-1050 kg / m³ for compact PS plastics. Current European consumption of expanded polystyrol is less than 2 million tons. It is necessary to add 400 thousand tons of XPS and approx. 100 thousand tons of foam PS foils used as packages and trays for food. Due to its low density it is a huge pile of waste.

Calculation model Degreedays (D°) have been integrated to the portal tzb-info.cz 10 years ago. This model enables determinate the count of Degreedays. For the calculation is possible to set up following data: internal temperature, external temperature and the date, when the heating season started and ended. The total number of observation stations in Czech republic gone up this year to 37 locations. For the calculation is possible to use the data from 2005 to present.

The goal of this paper was to inform about the development of the building integrated photovoltaic thermal (PV-T) system and evaluate its performance in compared to PV installation built of same photovoltaic cells. The study was collaboration among the Technical University of Denmark (DTU and Danish company RAcell (end-reference to website). This project was applied and optimized with the coupled house system on FOLD house, built in purpose of international student competition Solar Decathlon Europe 2012 held in Madrid in September 2012. The proposed PVT system was awarded with first price in Solar system integration sub-contest, during the competition SDE 2012.“Highly effective and innovative integration of PV and thermal systems that is not only a machine added to a house, but added value without creating too much attention to that machinery,” said one of the jury members about the PVT system, announcing the winner.
The PV-T is a hybrid system where the significant growth of efficiency of electricity generation is caused by cooling the cells to optimal temperature by system of embedded pipes on the backside of photovoltaic panels. The thermal part removes the heat, cools down the cells and increases its el. production up to 14,8 % according to PV system using the same cells in the same weather conditions. New solution was carried out for piping connection between panels. The house integrated PV-T system was compared with separate Photovoltaic and Thermal systems from energy and economy point of view. For annual usage of the FOLD house in Spain and Denmark was the PV-T system found as a more beneficial in compare to two separate systems.

Author of the article reflects on the contribution of the amended Decree no. 237/2014 Sb., issued by the Ministry of Industry and Trade on 7 November 2014, for increasing the energy efficiency of heating systems in buildings with central heating.

The issue of energy utilization of waste and the connected construction of new facilities is a very actual phenomena. The article addresses primary the trends of waste treatment and contemplates the option of energy utilization of waste from different perspectives. In a not insignificant part of the article is described the waste as a fuel, which means its composition and properties. This article is first from a prepared miniseries about waste.

Waste water that ends up in the sewer network contains a large amount of energy. Utilization of this energy, which is also available throughout whole year, is not yet part of the standard engineering practice in the Czech Republic. This article brings an inspiration in the form of experience from Austrian city of Amstetten, where was implemented a project, which is using combination of a sewage heat exchanger and a heat pump. State of the art as the same as the factors affecting the utilization of waste heat are also included.

The article, with its theme of gear just beginning to cell cycle at a relatively broad topic of “thermodynamic phenomena in the pipeline and its surroundings”, describes the current situation in the field of pipeline networks and in the field of energy related equipment, determining the operating condition of the whole heating systems. This is essentially a search condition and trends of modern heating, working as using conventional manufacturing processes, as well as the application of engineering principles and methods in the field of far less obvious. This two-part article, articles and downstream, is also setting research targets thermodynamic and hydraulic phenomena in pipes and in its vicinity, which gradually obtaining knowledge useful in practice, will be precisely processed using mathematical, mostly numerical, models.

While shale gas is being hyped as a green energy option, experience from USA shows that the dynamics of the industry is rather similar to a bubble. Europe has a different geology, its legislation is not ready and the technology itself has been shown to carry substantial risks for the environment and human health.

The highest representatives of more than 120 countries accepted the invitation to the UN Climate Summit 2014. In addition to these UN Secretary General Ban Ki-moon invited representatives of financial and commercial institutions and civil society. The aim was to encourage and accelerate climate action. Ban Ki-moon requested them to announce bold measures and actions to reduce emissions, strengthen climate resilience and mobilize political will towards meaningful legal agreement in 2015.
Representatives of Countries presented their statements, but only rarely there was mentioned a specific reduction in CO₂ emissions. Generally it can be said that most states are willing to contribute to reducing CO₂ emissions “appropriately”. The question is what this word means in their imagination.

District Heating Association of the Czech Republic in late July issued a press release in which reacts to the latest proposal by the European Commission. According to the Commissioner for Energy Günther Oettinger, EC is going to order that EU Member States ensure without obligation energy savings equal to 30 % by 2030.

Existing lapses and mistakes during renewable energy sources development planning can be now avoided via unique program called RESTEP. RESTEP can easilly find available resources at given area and determine whether it is worthwhile to use them or not. Aim of this article is to introduce RESTEP, what it is good for, how does it work, who developes it and who will benefit from it.
Data needed for planning of energy use of RES are now available in one place through interactive map called RESTEP (regional sustainable energy policy). Authors describe RESTEP as RSA - regional source assessment. RESTEP recognizes what renewable energy soureces the selected location can offer, and then this potential derives a proposal of optimal mix of energy technologies. RESTEP is being developed at the Czech Agricultural University in Prague in cooperation with the Ministry of Environment and a number of other institutions.

The article describes important new information about resolving the central heating. Heating is different from circulating water supply by solving transmission capability of pipe networks and by solving the power control. The article deals with the first of real heating characteristics – transmission capability of isolated and non-isolated pipe networks.

The history of photovoltaic begins with the discovery of the photoelectric effect in 1839 and later the photovoltaic effect in 1876. Practical application of photovoltaics came a century later, the earliest for power supply of satellites in 1958.
Turbulent development of the field followed, accompanied by the rapid decline in prices and increase of energy efficiency.

While the Czech Republic has imposed "moratorium" on offshore oil or natural gas from shale, the world is slowly unconventional method of production starts. Text describes and explains the process of "shale revolution" in the USA and compares the approaches to the same method of mining in several world regions and states. The author intends text and fulfillment of the conditions for the export options "shale commodities" globally and the implications of the massive expansion of exports of unconventional gas and oil.
