The modern building technologies are technologies of green construction, near zero-energy and active buildings with bioclimatic design, optimized energy consumption and CO2 emissions. Prospective enclosing structures of such buildings are structures using available, low cost, and environmentally friendly materials based on plant raw materials.
Based on the analysis of energy consumption and carbon dioxide emissions of the construction industry, it is stated that the reduction of energy consumption in Ukraine is achieved through termomodernization of the existing building stock and build new buildings, which meet energy efficiency requirements. Comparison of thermal parameters of different wall materials are given. It is shown that multilayer wall constructions must be used to ensure the necessary indicators of external walls of energy efficient buildings.
The article shows that one of the ways of realization of energy efficient building principles is the introduction of the technology of permanent formwork using monolithic concrete (technologies Quad-Lock and “Tehnoblok”). The use of concretes with high thermal mass provides thermal stability of the premises, decreases the amount of energy for heating and cooling, reduces the emission of greenhouse gases. Development of Ukrainian road infrastructure and its repair are required the use of rapid-hardening and durability materials.
Energy-efficient buildings or passive in the coming years should become a standard in Poland and Europe. Energy-efficient buildings are generally more expensive than traditional, so there are some psychological barriers before making a decision on their implementation. Despite a significant increase in awareness of investors in this area it is essential to disseminate knowledge about the need and benefits coming from the use of such solutions.
