“…Previous research has indicated that the primary factors influencing excavation deformation include the excavation geometry, support forms, seepage inflow rates, excavation soil, and excavation sequences [ 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 ]. Some scholars have optimized excavation design schemes through quantitative studies on individual influencing factors [ 28 , 29 , 30 , 31 , 32 ], providing new insights into excavation construction processes. However, these studies have often overlooked the mutual coupling effects of other excavation factors.…”

To investigate the impact of underground water seepage and soil stress fields on the deformation of excavation and support structures, this study initially identified the key influencing factors on excavation deformation. Subsequently, through a finite element simulation analysis using Plaxis, this study explored the effects of critical factors, such as the excavation support form, groundwater lowering depth, permeability coefficient, excavation layer, and sequence on excavation deformation. Furthermore, a comprehensive consideration of various adverse factors was integrated to establish excavation support early warning thresholds, and optimal dewatering strategies. Finally, this study validated the simulation analysis through an on-site in situ testing with wireless sensors in the context of a physical construction site. The research results indicate that the internal support system within the excavation piles exhibited better stability compared to the external anchor support system, resulting in a 34.5% reduction in the overall deformation. Within the internal support system, the factors influencing the excavation deformation were ranked in the following order: water level (35.5%) > permeability coefficient (17.62%) > excavation layer (11.4%). High water levels, high permeability coefficients, and multi-layered soils were identified as the most unfavorable factors for excavation deformation. The maximum deformation under the coupled effect of these factors was established as the excavation support early warning threshold, and the optimal dewatering strategy involved lowering the water level at the excavation to 0.5 m below the excavation face. The on-site in situ monitoring data obtained through wireless sensors exhibited low discrepancies compared to the finite element simulation data, indicating the high precision of the finite element model for considering the fluid–structure interaction.

“…The development of industry and transport, and the accompanying increase in energy consumption, has led to an acute dependence of mankind on energy resources. The increase in energy demand with the simultaneous complication and increase in the cost of energy resource extraction, as well as the aggravation of global environmental problems, have made energy saving and energy efficiency improvement an important area of development in many countries of the world [1].…”

The multifamily housing stock in Russia has a high degree of wear and tear, low energy efficiency, and inadequate maintenance, which leads to over-consumption of energy resources. High energy intensity is related to the fact that energy equipment is obsolete, high heat and energy losses during transportation occur, energy is spent by enterprises and population unreasonably, buildings and constructions have high heat losses. The main reasons for the efficient use of energy in the building sector is to reduce the heating and hot water costs of building owners, improve the indoor climate of buildings, save taxpayers' money in order to use the saved funds in other areas, introduce energy efficient and renewable energy technologies, improve the air quality, reduce the negative impact on the environment and climate change Based on the above mentioned, the article examines the aspects of energy efficiency of residential buildings, namely identifying the problems of energy efficiency, the main parameters of the state programme of energy efficiency of residential and public buildings. An example of potential incentives, comprehensive and reasonable use of incentives, which can change the current situation in the shortest possible time, is presented.
