北京农业大学图书馆设计竞赛的优胜案是在原来校园基础上成功的增建。由同济大学建筑设计研究院设计，其设计覆盖了所有建筑功能同时为学生的学习和研究提供了舒适的环境。该图书馆建筑面积约49,000平方米，包括一个自习区，一个餐厅，一个礼堂，若干办公室和会议室。本段后有更多图片和建筑师的描述。

该图书馆设有座椅3000个，藏书2,000,000多本，其内部功能都相互分开，以便独立运行。坐落于校园的东部，位于教学区和生活区之间。在南部有一个体育馆，体育馆前面还有一个大型公共广场，北部有一栋高层住宅综合楼。其北面挨着一个重要的科技楼。这块地在东北角沿着小月河西路向东延伸，形成约20,000平方米的L型地型。

我们仔细分析了该校园以构建尊重周围建筑和交通的设计。深知科技学院的重要性，我们从西侧延续了该学院教学楼的轮廓，同时将图书馆楼建在和它与道路相同距离的位置，因此，构成了类似的氛围。此外，我们还延续了宿舍楼的轮廓，以便在图书馆和校园边界之间构建某种绿色空间。基于此，我们的可使用场地面积为约10,000平方米。

经过物理模型和3D模型的多方尝试，我们最终采用了一种简单实用的规模和布局。该建筑6层楼高，底层楼高6米，标准楼高4.8米，整个楼高30米，这与毗邻的科技楼和体育馆一样高。这有利于构建和谐的校园空中轮廓线。建筑普通的外形有助于其融入原来的校园，加强校园的中轴。我们的设计还考虑到了北京较冷的天气。密集的建筑减少了外表面，这极大地较少了供热的需求。

该建筑精心布局安排，极大地考虑到了改善纵向循环的效率：经常使用的用途安置在较低楼层，如礼堂、会议室、餐厅和普通书架；而像档案室这样较少使用的用途则安置在较高的楼层。考虑到设置安全出口的必要性，我们决定添加第二套开放的楼梯系统。我们设计了较宽的楼梯，这不仅连接各楼层，还构建了高质量的学习空间。这些楼梯除了可以连接各楼层，还加大了正厅宽敞的空间。

阳光的直射会毁坏脆弱的书籍和封皮，可是，人们还需要光阅读。因此，阅读区沿着建筑表面一侧安置，而书架则安置在建筑较内侧的位置。由于书架在建筑顶部更密集，阅读区的需求变小。建筑正面符合自然光的需求。因此，在需要更多阳光的较低的楼层，建筑正面较为开放，而在需要保护书籍的较高楼层，建筑正面则逐渐封闭。

五楼的立体图受到了较多的关注，因为该建筑被许多高楼所包围。它由屋顶花园和天窗构成，这从某方面来看，与楼房的景观设计很像，这同时还极大地改善了6楼的质量。至于建筑正面的材料，我们再次尝试寻找一些与周围环境相适宜的材料。该校大部分建筑都是由褐色砖构成或是涂成大地的颜色。因此，我们选择天然的褐色石材。通过多种途径，例如：天窗、分散的正面窗户、礼堂和两层楼高的空间，建筑的内部空间最大限度地确保了阅读区的自然光照射，同时不让阳光直射损坏图书。

The competition winning proposal for the Beijing Agriculture University Library is a successful addition to the existing campus. Designed by Tongji Architectural Design and Research Institute, their design takes care of all the functions while providing a comfortable environment for students to study and research. With a construction area of about 49,000m2, the library includes a self-study area, a restaurant, an auditorium, several offices and some meeting rooms. More images and architects’ description after the break.

With 3,000 seats and space for more than 2,000,000 books, the functions of the library are separated internally to allow them to be run independently. The site is located on the east side of the campus, between teaching and living area. In the south there’s a stadium with a large public square in front of it while in the north there is a high-rise residential compound. Bordering on the west side is an important Tech. Building. The site expands east on the north/east corner along West Xiaoyuehe Road, forming an L-shaped site of approximately 20,000 square meters.

We analysed the campus in order to create a footprint that respects the surrounding buildings and traffic axis. Knowing the importance of the Tech. Institute, we continued the outline of the institute building from the West as well as offset our building the same distance from the road. Hence, creating a brotherly atmosphere. Furthermore, we continued the outline of the dorm building in order to create some green space between the library and the campus border. Out of this we had a usable site area of about 10,000m2.

After many attempts of physical models as well as 3D models, we ended up using a simple but functional massing and layout. It is a six-story building with a ground-floor height of 6m, and a standard floor height of 4.8m. Thus, creating a total building height of 30m which happens to be the same as the neighboring Tech. Building and the Gym. This helps to create a harmonious campus skyline. The regular shape of the building makes it fit well into the existing campus and strengthens the campus axis. We also took the cold Beijing winters into consideration in our design. Having a compact building reduces the exterior surface which helps to greatly reduce the need for heating.

The building is organized so that highly frequented functions such as the auditorium, the meeting rooms, the restaurant and the common stacks were located on the lower floor while less frequented functions like the archive were located on the higher floors. Thus, considerably improving the efficiency of the vertical circulation. Having set up the necessary fire escapes, we decide to add a secondary system of open staircases. We created wide stairs that, not only connect the different floors, but also create high quality space for studying. Besides having the function of connecting the different floors, these stairs also add to the magnificence of the atrium-space.

Direct sunlight destroys the binding and brittle books. People, however, require light to read. Therefore, the reading area was arranged along the facade, while the stacks got located further inside the building. As the stacks get more compact towards the top, the requirement for reading area becomes less. The facade follows the need of natural lighting. So, on the lower floors, where more light is needed, the facade opens up while it closes down on the upper floors to protect the books.

The fifth elevation was given a lot of attention since the building is surrounded by many high-rises. It is made of roof-gardens and skylight windows which, in some ways, resemble the landscape design of the building while, at the same time, greatly improving the quality of the 6th floor. As to the facade material, we, again, tried to find something that fits well with the surrounding. Most of the buildings are made of brown bricks or are painted in earth-like colors. Therefore, our choice fell on a brown natural stone.

Through a variety of ways, such as the skylights, the scattered facade windows, the atriums and the double height spaces, the interior space ensures maximum natural diffuse lighting for reading space without letting in direct sunlight that could damage books.
