Energy-active window blocks: constructive solutions and design

In Uzbekistan, with the increase in investments in the construction of residential, administrative buildings and structures, much attention is paid to the use of energy-saving and energy-efficient technologies at the initial stage of planning the construction of buildings and structures.

Taking into account the fact that most of the buildings and structures under construction are designed for long- term operation, i.e. 80-100 years, the maximum requirement is given for saving the use and storage of energy, which significantly contributes to the conservation of non-renewable energy sources and greenhouse gas emissions, taking into account energy requirements to ensure maximum energy efficiency of the system.

Along with the projected growth in the construction of new facilities in the republic, a corresponding increase in energy consumption in the residential sector is expected by 30% by 2050, which is expected to create a threat to ensure national energy security and increase greenhouse gas (GHG) emissions at the global level.

According to the measures implemented, both worldwide and in our country, today special attention is paid to the design and construction of energy-efficient and low-carbon residential buildings, buildings and complexes. The legislative and regulatory documents adopted in the republic, such as the "Strategy of transition to a green economy", the Law of the Republic of Uzbekistan "On the use of renewable energy sources", the Decree of the President of the Republic of Uzbekistan "On approval of the strategy of modernization, accelerated and innovative development of the construction industry of the Republic of Uzbekistan for 2021-2025" and others, contribute to the accelerated development of this industry in the country as a whole.

The generalization of the obtained research results of scientific communities proves the forecasts regarding global warming that has been happening recently around the world, which threatens climate chaos, and includes natural disasters, uninhabitable territories, a blow to biological diversity, an increase in the level of the world ocean, etc.

In order to prevent the negative effects of climate change, the world community is taking measures to prevent climate change. The Government of Uzbekistan also pursues the Sustainable Development Goals (SDGs) and has ratified the Paris Agreement, which defines the world action plan to curb global warming, than expressed "its readiness to contribute to eliminating the effects of climate change, which has no borders." Also, the government has recently been paying special attention to the renewable energy sector in the country, which in turn serves as an impetus for the development of projects of national scenarios and development models, as well as improving infrastructure in the country with ensuring energy independence in the near future.

The article presents possible ways to increase energy efficiency in the construction of new and reconstruction of old residential, social and household facilities with the use of energy-active translucent fences, i.e. window blocks in the planning and design of passive residential, social and household facilities, taking into account the thermal characteristics of the considered window blocks, as well as design solutions and design for their installation in the buildings in question.
