1. save energy: the library is a public building, usually with a lot of indoor space. External thermal insulation wall can reduce indoor and outdoor heat transfer and reduce energy consumption in warm winter and cool summer. This helps to reduce the energy use of buildings, thereby reducing carbon emissions and environmental impact.
2. Improve indoor comfort: The external thermal insulation wall can reduce the temperature difference between indoor and outdoor, and reduce the possibility of cold air or hot air entering the room through the wall, thus improving indoor comfort. This is especially important for libraries, because readers need a quiet, warm or cool environment to read and study.
3. Protect the building structure: the external thermal insulation wall can provide additional protective layer to reduce the influence of natural factors such as wind and rain on the building structure. This will help to prolong the life of the building and reduce the maintenance and repair costs.
4. Improve the appearance of the building: the external insulation wall can improve the appearance of the building and add unique style and characteristics to the library. Various colors and textures can be selected for external wall insulation materials to meet different design requirements.
To sum up, the significance of external thermal insulation wall of library lies in saving energy, improving indoor comfort, protecting building structure and improving building appearance. By adopting appropriate thermal insulation materials and design, these goals can be achieved and a better environment and experience can be brought to the library.
