Haikou, also known as the "Coconut City", is a southern coastal city rich in natural coastal scenery. The old Hainan Provincial Library, which opened in October 2007, is located in a coconut grove by the Meshe River in the city. As time goes by, with a growing collection of books and the emergence of the demand for minors’ reading and activity space, the reading space is in urgent need of updating and expanding.
The second phase of the library is located on the east and west sides of the first phase, including a children's building and a library building. The design hopes that the physical elements and space enclosure of the new library will be simplified while inheriting the garden-style heritage of the old library. It seems as a new branch growing from the old library, forming a harmony and unity with the original library. Outside the grove, time remains as before, while inside the grove, culture progresses every day.
Hainan Provincial Library is located in the Cultural Park of Guoxing Avenue, Qiongshan District, Haikou City, Hainan Province. The current condition of the site is harsh. The first phase of the project is located at the center of the site. The complex building of the Event Center and the Tennis Center left over from history on the south side cannot be demolished, so the buildable area of the site is divided into two parts, the retreat line on the north side is required to be the same as that of the buildings of the first phase, and the east side of the project needs to avoid the green barrier.
How to build new buildings in a limited site to meet the requirements of functions and scale, while ensuring their harmonious coexistence with the first phase, has become a topic worth thinking.
Therefore, at the beginning of the design, on the basis of fully respecting the existing buildings of the site, the designer considered to divide the buildings of the second phase into two parts and place them on the left and right sides of the first phase, connect them through the corridor, and locate them at the north side of the site in a growing manner. By doing so, the original functional ecology of the site is not disrupted, but a good interface facing the main street can be provided. At the same time, this design preserves the original vegetation of the site to the greatest extent possible.
The semi-enclosed layout of the new building extends the courtyard of the first period, becoming a natural transition between the main square and the inner courtyard. The form of the roof and facade of the second phase continues the texture and form of the old library. The whole group of buildings harmoniously coexist with the environment of the park. Under the background of the fireworks in the surrounding streets, they highlight a peaceful atmosphere.
In order to emphasize the cohesion and radiation of the provincial library, the second phase follows the north-south central axis layout of the first phase. The designer placed two new buildings symmetrically on the east and west sides of the site, and strengthened an east-west landscape axis running through the courtyard. The main entrances of the east and west buildings were set on this axis, forming a view relation with the courtyard of the first phase. This strengthens the connection with the first phase of the project. At the same time, together with the Provincial Fitness Center, the Culture and Art Center, and the History Museum located on the right side, it forms the main art interface of Haikou Cultural Park facing Guoxing Avenue on the north.
The architectural style of the second phase continues the design concept of "integration of the park and the library" of the first phase. Through the gardening techniques of traditional Chinese gardens, the buildings of the first and second phases are integrated and enhance the beauty of each other. The whole base bears the public supporting facilities needed by the new and old pavilions, fully realizing the sharing of public resources. At the same time, it integrates the first and second phases of the library, guides the gathering and evacuation of people, provides the public with a modern reading space integrating books and reading, and builds a good atmosphere of cultural exchange and sharing.
The library is a cultural landmark. The cultural atmosphere of a city is where the library is.
The second phase of the project embodies the concept of "cultural landmark" in the overall image of the architectural design, and drives the vitality of the entire library area with the overall image. The facade of this project is made of dry hanging light grey natural granite panels, the windows are large, the contrast between glass and stones is clear, and the visual impact is strong, the window modules are unified and full of rhythm, thus creating a calm, stretching, atmospheric architectural image.
Under the rigorous appearance, the details of the buildings and the landscape design need to be interesting and varied. In terms of architectural details, segmental gutter pitched roof, hollow ridges, and orderly drainage enrich and improve the monotonous appearance of traditional large-slope roof and the effect of waterproof and drainage. The outer walls are with concave vertical lines of double columns, appearing straight and neat. The large glass windows and the solid walls produce obvious contrast between virtual and real; the large sun shading structure is interspersed with metal louvers, showing a unique elegance, enhancing the beauty and affinity of the buildings. The internal interface of the building is integrated with the man-made landscape to create a garden reading environment that is varied and harmonious.
The external image of the site represents the cultural connotation of Hainan Library. It embodies the people-oriented concept of design, creates a building group with a sense of centering and belonging, and creates a humanized and landscaped reading and learning environment, becoming the core and key of this project.
The north, east and west facades of the second phase are with dry hanging light gray natural granite panels, and the south and courtyard facades are with light gray stone-imitation paint. The colors are coordinated and unified, and the joints are smooth, even and straight, with clear forms and a sense of rhythm.
The echoing of these macro volumes and the coordination of micro details give the building an image of purity, simplicity and rich cultural connotation, showing the elegance and gravity of dignity of cultural facilities; the design of the interior space is very humanized, and the details are well set. Certain changes have been made in the reading mode, abandoning the traditional reading mode and adopting the modern immersion reading experience integrating collection and reading.
In addition, the interior facade of the building courtyard is designed to be more transparent and create rich character changes through light shapes. The design forms a flowing and permeable architectural space, suggesting a humanized library image full of vigor and vitality under the rigorous and steady appearance of the architectural group.
This project adopts BIM professional design, unified modeling, standardized design, factory production, assembly construction, integrated decoration, and integrated toilet and pipeline separation technology, with an prefabrication rate of more than 50%.
The seismic fortification intensity of Haikou City is 8 degrees, and the designed basic seismic acceleration value is 0.30g. In structural design, the effect of earthquakes is reduced by more than 60% through the use of earthquake isolation and absorption technology. Therefore, the structural form has changed from the frame-shear wall structure, which requires a large number of walls, to a general frame structure, which creates favorable conditions for the flexible layout of the building space, and also significantly improves the seismic performance of the structure.
The east building of the second phase of Hainan Provincial Library is the Children's Reading Building. It is a seven-storey building with one floor underground and six floors above ground, with a total construction area of 13,350 square meters. It covers the following functions: open reading hall, leisure parent-child borrowing, picture book borrowing, classic children's book area, primary and secondary school borrowing, adolescent periodical reading room, training classroom and book storage, etc.
In each floor of the building, according to the different age groups, based on the characteristics of children at each stage, the design conducted a need analysis of the corresponding spaces, and designed the corresponding function spaces. According to the ages, the reading rooms are distributed in a low-high manner, making it more convenient for children of different ages to use. At the same time, a colorful environment can stimulate children's imagination, enrich their emotions and cultivate their personality. In this way, in the city of a steel forest, it creates a childhood tribe for children and creates a colorful childhood for them. The design introduces color into the interior to support the diffusion of vertical traffic from the core to the perimeter. In terms of color, from bottom to top, as children grow older, bright colors are gradually replaced by calm and modern colors, which accentuates the space atmosphere and not only enhances the space characteristics but also symbolizes the accumulation of children's knowledge and wisdom.
In terms of sound absorption and noise reduction, considering the characteristics of children's reading, the design first separates dynamic and static areas to avoid interference. At the same time, the design adopts sound-absorbing wood veneer and the sound-absorbing ceiling made of silicite plates for sound insulation treatment for the reading space and ensure a good sound environment for reading.
In order to ensure the safe reading of children, the space is designed to be open, the furniture is low, and the soft decoration is based on rounded elements, which is comfortable and warm. Colors are mainly warm, with appropriate supplement of other colors, bookshelves, tables and chairs and other furniture are with a lively style, so as to improve children's interest in reading. At the same time, modular furniture settings are used to create the conditions for the combination of multiple functions. The most widely used rubber floor in the interior space uses the “Armstrong” green rubber imported from America to provide a comfortable and green reading space for children.
The west building of the second phase of Hainan Provincial Library is the building of book collection. It is a seven-storey building, with one floor underground and six floors above ground, with a total construction area of 19,950 square meters. In the near term, it mainly adopts the form of dense bookshelves, and in the later stage, it will consider the use of smart bookshelves, which can store and sort books through fully mechanized means, so as to comprehensively improve the collection efficiency of Hainan Provincial Library.
