STRUCTURING OF MEASURES TO REDUCE ENERGY CONSUMPTION OF GREEN BUILDINGS WITH ELEMENTS OF OPTIMIZATION OF GEOMETRIC PARAMETERS

The relevance of designing green energy-efficient buildings is growing due to the global challenges of climate change, the depletion of natural resources and the need to reduce greenhouse gas emissions. Such buildings allow for a significant reduction in energy consumption, using innovative technologies, renewable energy sources and environmentally friendly materials, which not only contributes to the preservation of the environment, but also provides savings for owners and tenants. In the context of strict environmental standards and the growing demand for sustainable and effective solutions, green buildings are becoming an important element of sustainable development and competitive advantage in the construction industry. When designing and reconstructing green buildings, the task lies in determining the means and level of their impact to increase the energy efficiency of buildings. The article proposes a framework of measures to increase energy efficiency and reduce energy consumption of green energy-efficient buildings. The measures include optimization of the geometric parameters of buildings (shape, orientation, area of elements, heat transfer resistance, etc.), geometric parameters of engineering systems that ensure the use of environmentally friendly energy sources for energy supply of buildings. Research was conducted and the weighting coefficient of the impact of each measure (limits of permissible effect) was determined and analytical dependencies for calculating the impact of measures on building consumption were proposed. Thus, a method for preliminary determination of energy consumption through the use of certain energy-efficient measures was created for the designer and energy auditor. When performing new construction and reconstruction of a green building, the designer receives a method for quickly assessing changes in energy consumption due to energy-efficient measures. A study was conducted and the structure of measures to increase the energy efficiency of green buildings and reduce energy consumption was proposed. The weight coefficients Kx.x from the application of each of the measures are determined and analytical dependencies for determining the reduced level of energy consumption of DQop buildings are given. Measures related to optimization of geometric parameters of buildings and engineering systems are defined. The designer and energy auditor during the thermal modernization of the building, and during new construction, using the given structure and analytical dependencies, can determine further measures to obtain a building with a reduced level of energy consumption.
