On the day lighting in school buildings of architectural design


Paper Keywords: day lighting; active; passive; strategy Abstract: daylight illumination than artificial lighting presents many advantages make the day lighting design has been Architectural Design at an important position. With the college teaching building construction scale, diversification, the development of intelligent, the more natural lighting design requirements. In this paper, this type of school building construction, and explore the architectural design of the implementation of day lighting strategies. 1 Introduction day lighting is to introduce daylight inside the building, and its allocation according to certain order to provide better than artificial light and the quality is more good lighting. Day lighting to reduce the power requirements for light sources, reducing power consumption and environmental pollution. Studies have shown that day lighting can form more than the artificial lighting system and a more exciting environment, health, work efficiency can be increased by 15%. Daylight Lighting can also change the intensity of light, color and vision, help to improve work efficiency and learning effectiveness. With the development of social productive forces, the training to become a vital part of technological progress. In recent years, multi-disciplinary university gradually to the development of a comprehensive university, many colleges and universities in size and quality of teaching continuously adjusted to adapt to the new needs of the times. College planning and construction is becoming a new topic, colleges and universities with school building design is also planning to expand the scale has changed. The volume rate teaching building, the classroom use of the area is gradually increasing, the classroom room for light, illumination design of a more complex requirements, embodied in three aspects: First, the larger bay. Increase led to longer-horizon bay, rear seat platform in order to ensure regional and the brightness of the normal requirements of the board, and its illumination design is more complex. Second, depth increased. In order to design an effective seat view, will inevitably affect the larger bay deep into the building. Increased the depth on both sides of the classroom can enhance the effective line of sight area. Deep into the classroom ranging from 6m to 13m, or even more. Third,[link widoczny dla zalogowanych], the window than the decrease. The classroom and into the deep bay has a tendency to increase, although the structure and space for various needs, the height will increase, but also considering the energy-saving design and cost control, windows down than the bound, both indoor illumination good sex would be difficult to achieve. Secondly, the thickness of the beam will be on increasing the interior space to form a highly effective, reducing the roof of oppression, the story is bound to increase the classroom. In order to not only save construction costs, and meet the energy standard, window area and the indoor use of the effective transmission ratio of the area ratio of window to the inevitable decline. How good of both the indoor illumination, is worth studying. Although these problems can power source to achieve, but over-reliance on artificial lighting system is not conducive to saving energy and protecting the environment, artificial lighting Moreover, the user will continue to produce a certain psychological pressure. Survey showed that: 90% of employees prefer to have windows and can see the outdoor room with a view to work, a result of a study is 75% of the office and factory workers that the high quality of daylight than artificial light. Therefore, in order to create a teaching building of this place easy to learn positive learning environment, we need to capitalize on the trend under these adverse trends, design superior daylight lighting. 2 day teaching building lighting implementation strategy day lighting in the choice of the specific measures before the construction of school buildings to conduct a scientific body selection, should be chosen for the solar lighting, solar radiation, heating, cooling and building features the most compact trajectory and shape of the building. Is the volume of space surrounded by the outer surface corresponding to the larger outer surface of indoor heat exchanger by its greater impact. However, the design of school buildings in the actual application, the pursuit of space to improve thermal efficiency change and become a Comparison of the Yangtze University New Campus in several construction bidding program, you will find intricate space-level changes more able to attract the attention of Party. Founder of the teaching building of the traditional first provide the most intuitive features - school, learning. And rich space scattered, physical changes in the height difference, view per step of the shared space, it seems at first sight Gengrang students. How to make it do both? Teaching building by comparison of several buildings observed changes in shape of the bump, the space scattered echoes, greatly enriched the form of four towards the window and lighting needs. Same thing to, some with sun-based, and some have to the introduction of daylight; same from north to south, and some classroom learning space for the lighting, walkway lighting and some to share. Quantity and variety of new lighting requirements are the amount of shade change, the corresponding day lighting strategy is also different. If you use from the building of the type of sunlight, daylight lighting can be divided into two strategies. Cover the main light is not a passive day lighting strategies, the other is a light-based initiative to introduce a pleasant day lighting strategies. 2.1 passive day lighting strategies work in non-direct sunlight is beneficial to the region, it can make people know that outdoor weather conditions and time. In the absence of these factors can ease the pressure on the window environment. However, if a key work area by direct sunlight, will produce an unacceptable contrast, people temporarily blind or hidden radioactive glare. The key work areas to avoid direct sunlight and excessive brightness control has become the focus of a passive day lighting. Shade to avoid the inappropriate use of 2.1.1 China since ancient times, light hundred pages of various wood shutter panes and various forms of shade measures used in different forms of architecture. In order to adapt to regional climatic characteristics of the architectural design, the architects devised a number of design solutions. The creation of shade structure is based on the consideration of climate adaptation is to shade structures together with the glass facade, it has undergone a simple external components directly from the integrated development of the building structure. Traditional architecture in the shade under the sun exposure when he was with the high thermal capacity of concrete slowly heating, heat conduction with the flow of air into the room. Therefore, using some of the more compact building design, appearance, ease of installation, cleaning and maintenance products. For example, perforated aluminum facade on the summer because the existence of the cavity can be more effective in reducing heat load, heat dispersion. Outside the sun visor is a simple way. Shading can generally be divided into two categories: fixed the shading on the building known as the fixed external shading, otherwise known as the activities the sun. The south or near south windows, the height of summer, when sun angles higher, setting a fixed horizontal sun visor to meet requirements. The sun shade can form a great area, in lowering the surface temperature of the south wall and windows to prevent direct sunlight achieve a good shade.
