1-Application of light in architecture
People's aesthetic feeling of light environment is very wonderful. Physiologists believe that different wavelengths of light stimulate the nervous system of the brain, and its intensity and structure can be different from people's external physical structure, physiological sensory structure and social emotional structure. However, people's perception of light elements in buildings also stems from the basic demand of light energy by organisms. At the same time, human demand for light element Li Yan is not only biological. People consciously organize space and light in architecture, and actively obtain the basic information of aesthetic experience from it. From the phototaxis of biological instinct to the conscious introduction of light into caves and huts by primitive humans, and then to the liberation of light sources by modern architectural structures, people and demons have become more and more active and free in controlling light elements, and at the same time, people's perception of light elements has become more and more divorced from biological sociality. The creation of architectural light environment can not be separated from people's rich imagination, which can be divided into general perceptual imagination and creative imagination. The former is usually created by the space of the building itself, while the latter is the atmosphere that architects can achieve in the form of imaginary light when designing the building structure and opening windows. This is our master architect's understanding of light and the correct application of light in architecture. In Tadao Ando's water church, architects made full use of natural light to form a "cross" in the church, liberating the cross from solid objects and replacing it with illusory light and shadow. The light became bright against the dark background. Only through light can we feel the existence of extremely abstract nature. Not only can you feel the information brought by light elements, but you can also feel the specific emotional experience. In the church, it can reflect the relationship between God and nature and create a special atmosphere, which cannot be said to be the ingenuity of architects. In other buildings, modern architects can also fully consider the influence of light on the architectural environment, make good use of light by their own means, and create the atmosphere they want.
2- application of heat in architecture
The knowledge about heat in architectural physics includes indoor thermal environment (the degree of thermal environment when people are comfortable indoors), the conduction mode of thermal energy (helping us to better control the accumulation and diversion of heat), and the thermal insulation of buildings (having a good thermal environment for human beings).
Now, people have begun to pay attention to coating thermal insulation materials on the external or internal walls of buildings to create a good indoor environment and reduce the impact of the external environment on the indoor environment. Human comfort can be achieved at any time. Nowadays, greenhouses are very common in some places. They artificially created a thermal environment in which plants can grow in winter, so that plants can grow out of season. They enclose the space with thermal insulation materials, cut off the heat exchange with the outside world, and then produce heat artificially in the greenhouse to make the plants grow well. In architecture, heat is mainly reflected in the thermal insulation of the building, and there is a main way for the thermal insulation of the building. 1 is the design of architectural modeling to minimize the total area of external protective structure. 2. Keep the structure with sufficient heat insulation performance; 3. Strive for good orientation and suitable building spacing; 4. Enhance the sealing performance of the building to prevent the adverse effects of cold air infiltration; 5. Avoid dampness and prevent condensation on the wall. Thermal insulation measures are also considered in these aspects, but the methods are different from the leading ones. Civil residence pays special attention to thermal insulation performance, and also plays an energy-saving and environmental protection role. Especially in the era of strong environmental awareness, energy-saving and low-energy buildings meet people's requirements for architecture. Acousto-optic heat in architectural physics has different characteristics, which can add bright colors to buildings. In modern architectural design, it is necessary to build a better building through the skillful hands of architects.
