Abstract
The article researches issues related to the relevance of applying renewable energy sources for civil engineering. The aim of the work is the study of modern approaches to designing buildings, using low-grade energy of the ground. The research methodology is based on the complex analysis of international design experience and on identifying the strengths and weaknesses of objects that use low-grade heat. We have identified the prospects of applying it for domestic construction practice. The state policy in the field of the efficient use of energy resources has been analyzed, and the vector of energy-saving programs development for the Samara Region has been defined. The research describes the impact of using geothermal energy on the architectural and planning solutions of buildings, as well as the peculiar features of the latter’s design, which are related primarily to the increase of energy efficiency. As a result, in the article a conclusion is made that the objects under investigation may be considered as one of the vectors of sustainable architecture development.
Highlights
At present, all over the world in energy industry a number of problems may be pointed out first, the problems connected with the limited amount of raw materials, and second – the ones connected with environment pollution
The main part of engineering equipment - various types of heat pumps and heat exchangers - are located below ground, there are special technical devices in the housekeeping area of the building
During the construction of buildings of this type a pile field is often used as the foundation structure, which may be used as a geothermal energy collector, and this allows reducing investment costs
Summary
All over the world in energy industry a number of problems may be pointed out first, the problems connected with the limited amount of raw materials, and second – the ones connected with environment pollution. Renewable (regenerative) energy, in other words - "green energy" – is a form of energy, produced from sources that are inexhaustible by human standards. Among renewable energy sources (RES) we may name the energy of the sun, water, wind, biomass, the thermal energy of the upper layers of the earth's crust and oceans [3]. Their main advantages are that they are inexhaustible, environment friendly, besides operating costs are low. The volumes of used regenerative energy are determined by economic expediency and competitiveness with traditional energy technologies
