Save Energy

Ecology and environmental protection have been discussed more and more in the last few years. This trend was also affected by the construction and architecture department. Concepts such as green building, environmentally friendly materials, alternative energy sources and energy-efficient construction systems of buildings are depressed. All of this comes under the name "Green Buildings". Wood-based construction and material solutions are a response to these trends. Investors and users are gradually starting to think more environmentally friendly and therefore many times also make decisions for wood-based constructions. There are several systems that fall into the category of so-called crushed buildings. The aim of this work is to provide a look at the "greener" options offered in the construction industry with an emphasis on their energy and thermal characteristics. The subject of the research was selected structural parts of timber-based buildings applied to model constructions by means of which selected thermal-technical characteristics were evaluated. This work points out the differences between the compared design variants of wooden buildings in terms of their ability to effectively save energy sources for heating inserted during the operation of wood-based buildings.

Willingness To Use

In Poland, domestic hot water is heated mainly using fossil fuel energy sources. Such an approach results in the depletion of natural resources, pollution of the atmosphere and, consequently, irreversible changes to the climate. In response to this problem, this research identified the factors that most determine energy savings for heating water in residential buildings, as well as those that affect the choice of an alternative energy source. Additionally, the possibility of implementing shower heat exchangers in existing and newly built residential buildings was assessed, as well as society’s willingness to use such devices. The research was carried out on a sample of 462 inhabitants of the Podkarpackie Voivodeship (Poland). A questionnaire survey was used as a tool. The conducted research has shown that the perspective of environmental protection is not a sufficient motivator to save energy for heating domestic hot water. It is necessary to implement appropriate programs aimed at informing the public about the possibilities offered by the use of alternative energy sources and co-financing the purchase of appropriate devices. In the case of drain water heat recovery systems, a significant problem is also the need to develop new, highly effective designs of shower heat exchangers which can be installed under the floor linear shower drain or on the horizontal shower waste pipe.

Significant Attention

The urge to use alternative energy sources has gained significant attention in the eye of chemists in recent years. Solution-based traditional syntheses are extremely useful, although they are often associated with certain disadvantages like generation of waste as by-products, use of large quantities of solvents which causes environmental hazard, etc. Contrastingly, achieving syntheses through mechanochemical methods are generally time-saving, environmentally friendly and more economical. This review is written to shed some light on supramolecular chemistry and the synthesis of various supramolecules through mechanochemistry.

Modern Technologies

In modern conditions the building can not only consume energy from the outside, but also produce its own. A new role has acquired such energy sources as the sun and wind. Energy saving in architecture follows from the requirements of regulatory documents and includes: the use of alternative energy sources, the installation of energy-saving equipment. Using examples of modern technologies, it is shown that along with energy savings, it is possible to create environmentally friendly and more interesting architectural images. The basics of the formation in the architecture of energy-efficient spaces, methods and techniques of using the energy of the future in the architecture of Kazakhstan are studied.

Key Steps

Subject. The article discusses limited sources of energy nowadays and an ongoing survey of new ones. I focus on fuel and energy complexes worldwide and in Russia. Objectives. The study is to analyze the future use of alternative energy sources in the fuel and energy complex nationwide and worldwide. I review the existing energy sources of the fuel and energy complex in the global and regional markets, specifically the alternative ones. Methods. The study relies upon methods of statistics, analysis and systems approach. Results. The article demonstrates that the fuel and energy complex strongly depends on the current situation in the energy resource market, which is difficult to forecast. If we continue relying on traditional energy resources, we get exposed to some risks affecting the sustainable development of the economy. Russia should diversify the power engineering sector by developing alternative energy sources. The article sets forth the economic rationale for alternative sources and key steps Russia shall make. Conclusions and Relevance. Considering the current situation in the energy balance, alternative energy is what any advanced society seeks for, being supported by manufacturers, governmental institutions, and researchers, though low profitability and high infrastructure costs impede its development. In Russia, these challenges are even more palpable. However, even now Russia is able to find alternative energy solutions. In addition to advantages of alternative energy, which is globally proclaimed, they will also help Russia diversify and update the economic system.
