The article is the result of surveys conducted in the work of raw material and energy department statistics, the Ministry of Industry and Trade. Material published in August 2011 includes data on molded (formed) fuels (briquettes and pellets) made from biomass (wood and plant), peat, coal and paper.
On the day of the autumnal equinox in the U.S. started its fifth year of the prestigious international competition Solar Decathlon 2011. In this competition university teams from all over the world competed in building of energy efficient houses. In this ten-day contest containing ten disciplines was the most successful team of The University of Maryland´s this year.
Department of raw material and energy statistics of the Ministry of Industry and Trade dealt with detection rates of solid fuels in 2009, especially briquettes and pellets, under which in December 2010 issued material with the statistical evaluation of items: wood and plant pellets, wood, plant, paper, coal and peat briquettes.
For some time I start to have an allergy to the word ecology and ecological architecture. These words can mean many things, depending on what you need. So I'll try to put my opinion into a more specific framework. What is green architecture? Why is modern architecture abnormal when waste is normal? What is the situation in the Czech Republic for the use of "POTENTIAL SAVINGS?" How is the Czech Republic architecture environmentally friendly?
The contribution is focused on the systems of cool production for air-condition units. The first part of the contribution deals with the now-a-days cooling requirements of buildings. Then, the frequently used cool production systems are described and compared each other. The absorption cooling systems and the vapor cooling systems are compared. The most frequently used applications of the cooling absorption cycles are presented, namely tri-generation systems and district cooling systems.
In relation with the present discussions on the use of solar energy it is useful to mention one important stage of Czech agriculture - the production of really high-quality roughage. Besides the development of methods of silage and haylage, thirty years ago the researchers looked at final drying of forage in large-scale haylofts using air solar collectors.
The paper deals with identifying suitable areas of use of small cogeneration units fossil fuels and renewable energy sources in municipal and industrial uses. Discusses the advantages and disadvantages of cogeneration units based on internal combustion engines, gas turbines and steam engines, including their position in the electricity grid
The service life of photovoltaic panels is currently estimated at least 30 years. However, in the ideal case, it can be doubled up. Panels are recognised as a source of valuable raw materials too. Even though solar panels do not fall under the scope of European directives on waste management, manufacturers and suppliers have created a voluntary program of PV Cycle.
Projects of the International Energy Agency show that use energy more efficiently has a greater potential to reduce CO2 over the next 20 years than all other options combined. The main objectives of intelligent networks are improving the efficiency, reliability, safety and environmental sustainability.
Article gives an overview of support for electricity generation from biogas in the European countries and a comparison of purchase prices in selected countries. Purchase prices in the Czech Republic are comparable with other European countries. After the abolition of capital grants, a significant reduction of the interest of investors can be expected.
The Government draft of Act on the Supported Sources have to replace the existing Act No. 180/2005 Coll. on the Promotion of Renewable Sources. At the same time it have to apply to the Czech legislation requirements of the Directive 2009/28/EC on the promotion of renewable energy sources. Professional association representing all RES joined together to prepare amendments to the draft.
Comparison of knowledge in the field of wooden buildings between the CR and abroad is especially based on the author's many foreign visitors of completed buildings, businesses and universities, the knowledge of the extent and quality of especially American and German literature and participation in many international conferences, including the last World Congress of timber engineering WCTE, held in June 2010 in Italy.
Nowadays there is a growing interest in quality and high energy saving housing. The following article presents the almost unusual renovation of a terraced building in Denmark. It was expected that after the renovation the building with become CO2 neutral. The last house of a terrace in the twon of Albertslund, Denmakr was chosen for the renovation. It had been built in the 1960's and it is a two story terraced house with a 50m2 footprint.
