Come to Shuimoxiansheng.com to check out more content about the twelfth month of the lunar calendar in 2021!What is the difference between the Great Cold and the Winter Solstice?According to the "National Standard of the People's Republic of China Urban Residential Area Planning and Design Code":The sunshine standard for residential buildings in large cities is ≥ 2 hours on the Great Cold Day and ≥ 1 hour on the Winter Solstice. The sunshine standard for residential buildings for the elderly should not be lower than 2 hours on the Winter Solstice. Therefore, the Winter Solstice and the Great Cold are the best times to check the lighting in the house. Because the winter solstice is the day with the shortest daylight hours, but depending on the orientation of the building, it may not be the day with the shortest daylight hours for full windows of your building; and the Great Cold Day is generally the coldest day, and also requires sufficient daylight hours. What is the sunshine standard?Architectural sunlight studies the relationship between sunlight and architecture and the application of sunlight in architecture based on the principle of direct sunlight and sunlight standards. It is an important topic in architectural optics.The purpose of studying building sunlight is to make full use of sunlight to meet indoor light environment and hygiene requirements, while preventing indoor overheating and meeting the needs of building lighting. For example, special places such as kindergartens, nursing homes, and hospital wards need more sunlight. In addition, the calculation of sunshine cannot rely on the sunshine spacing coefficient, but should use a program certified by the Ministry of Construction to simulate sunshine conditions. The sunshine spacing coefficient is a very incomplete design basis. With the popularization of computers, the calculation method has been improved to computer sunshine analysis.
