The construction of residential buildings and structures is a complex process in which the economic component plays key role. It essential to maintain balance between saving materials costs additional engineering solutions while ensuring functionality comfort building’s operation. To achieve this goal, researchers initially analyze impact climatic environment spatial planning solutions—i.e., building shapes—that directly affect compactness ratio when evaluating efficiency designed building. In regard, objective study was shapes orientations Republic Kazakhstan across eight territorial units located I, III, IV zones latitudes 42°18′ 52°16′ N. identified most favorable for each zone: meridional orientation preferable I III zones, latitudinal optimal zone.

In this study, the authors conducted a comprehensive review of scientific and technical literature in field heat transfer outdoor enclosures with an air layer composite material, reviewing effect solar radiation on these areas. The problem was carried out both at national scale Republic Kazakhstan international level. It found that impressive number scientists are involved topic, which is confirmed by recent reviews, analyzed more than 2700 relevant reports. also reviewed chronology development hinged facade systems made material scale. Following review, critical analysis most appropriate works, where contradictions discrepancies results were found. Taking into account circumstances, proposed to investigate effects climatic parameters considering barometric pressure. Using regularity ideal gas equation, dependences change volume (air) when exposed temperature loads influence pressure determined. obtained will elucidate future research directions can be taken further studies fences territorial terrain.

This manuscript presents a theoretical study of newly developed energy-efficient external wall structure in comparison with traditional ventilated facade. To conduct numerical studies based on mathematical models the heat transfer water vapor filtration through multilayer filler and non-ventilated air gaps, calculation method was that additionally considers presence heat-reflecting screens different variations geometric parameters gaps thermal insulation layers. The results demonstrated new 6.1–7.2% more efficient terms resistance than one, due to screens, efficiency increased 15.2–16.3% depending layers structure. In addition, all considered variants geometry (i.e., closed gaps), there were condensation zones, but it established according value inadmissibility moisture accumulation structures, over annual period operation, structures complied standard climatic conditions Shymkent. this thus positively complement existing catalog can be used while considering necessary heat-insulating when designing buildings corresponding conditions.

A possible way to solve the problem of energy saving in construction is introduce energy-efficient buildings at design stage and, particular, during retrofit. Therefore, purpose this study conduct a theoretical analysis thermal resistance and loads on building cold climatic conditions. The these values was carried out ANSYS software package Maple computer algebra system, respectively. This examines four types structures: existing facade constructed 1966, traditional ventilated facade, two designs featuring alternating insulation layers with enclosed air channels or without heat-reflecting screens layer. results show that new incorporating layer 1.15 times more terms than proposed such screens. effectiveness also confirmed through an protection building, where auxiliary indicators, specific characteristics, complex efficiency load greater efficiencies 1.6, 1.03, 1.05 times, respectively, compared other studied structures. comprehensive research presented indicate use wall structures for retrofit external enclosures can significantly improve performance buildings. It determined enhance building’s overall rating. findings highlight solutions contribute significant savings buildings, while newly developed serve as valuable additions catalog designs.

The energy consumption requirement of high-rise buildings necessitates effective innovations in architectural designs. aim is to revolutionise buildings’ thermal features and efficiency. This paper combines quantitative analyses through improved simulations qualitative information from surveys stakeholders, including architects, engineers, urban planners. Key performance indicators such as U-values, R-values, HVAC efficiency, Solar Heat Gain Coefficient (SHGC), Energy Use Intensity (EUI) are examined detail assess the contemporary façade systems. Energy-efficient building design paramount this time unprecedented development escalating global temperatures. However, a gap exists understanding how these practices can be adapted integrated effectively into modern architecture. findings show that high-rises with optimized pattern curtain wall façades reveal considerable savings usage, particularly cooling loads, which enhances indoor comfort reduces environmental effects. Actionable recommendations provided for urbanists, policymakers, designs region-specific constructions, their connection renewable energy, compliance high standards. All strategies help improve operational sustainability, stability built environments growing, developed areas.
