The article analyses key aspects of the light insolation mode, such as the effect of sunlight on the temperature regime and illumination of window systems. The importance of the light insolation mode in the design of energy-efficient windows and translucent enclosures is considered.
The role of the light insolation mode in the selection of energy characteristics of window systems to improve the energy efficiency of buildings is determined. Translucent enclosures are studied to improve the energy efficiency of buildings through window systems. Some modern approaches to reducing heat gain through translucent window structures are summarized.
The characteristics of double-glazed windows with various properties, such as the level of sunlight transmission and heat transfer coefficient, which directly affect the efficiency of energy saving, are considered. The behaviour of sunlight and its interaction with window structures are highlighted. A numerical analysis of the thermal efficiency of external vertical enclosures of buildings is carried out.
A method for graphic-analytical assessment of the light-insolation mode is formulated, including computer simulations that allow predicting illumination and thermal conditions. The data obtained as a result of thermal imaging surveys help to evaluate the efficiency of the proposed design solutions. A method for modelling types of window systems and other translucent structures in a non-stationary heat transfer mode is proposed.
As a result of the research, mathematical dependencies were established to identify the heterogeneity of the thermal field in vulnerable parts of the translucent enclosure. This determines the direction of rational design of buildings taking into account vulnerable areas of both traditional and new structures, as well as during the energy audit of facades.
Real data on the illumination and thermal conditions of window systems obtained as a result of an energy audit for non-stationary heat transfer, as well as with the help of thermal imaging surveys and the use of a software package, allow us to evaluate the energy efficiency of the proposed design solutions for window systems.
The prerequisites have been created for the development of a theoretical method for physical and mathematical modelling of temperature fields in translucent building envelopes under various non-stationary thermal exposure conditions in regions with a predominantly warm climate.
