basic information
**Lecture Summary** As global warming progresses and the instability of Earth's weather increases, various measures for reducing the use of Earth's resources and electricity have been proposed and implemented. Currently, regarding "heat-shielding and insulating materials for windows," in addition to improvements in window glass structure, there are structural modifications that can be retrofitted and sunlight adjustment using window films, with a wide variety of energy-saving technologies available on the market. Among these, this presentation summarizes the latest development trends of "heat-shielding and insulating transparent films for windows," comparing energy-saving effects and addressing issues such as thermal cracking and condensation after installation. It also compiles the annual energy-saving effects of various proposed window films in relation to the revised energy-saving law aimed at zero-energy houses, along with key points for usage by type, and discusses simple calculation methods for identifying issues. Depending on the application and method, it is necessary to select and improve performance in response to issues such as condensation and thermal cracking, which are problematic for heat-shielding and winter heating load reduction, tailored to regional climates. The presentation outlines the calculation methods necessary for thermal transmittance and shading coefficient calculations, as well as formulas and methods for calculating glass temperatures when assessing the occurrence of thermal cracking and condensation, summarizing the effectiveness of window films required for future changes in window forms.
