Jiangning District of Nanjing has the reputation of "Six Mountains, One Water and Three Plains" since ancient times. The project is located on the lakeside of Baijiahu Lake, with a superior geographical position. The hotel is a high-end building with prosperity and tranquility.

In terms of the appearance, "L"-shaped layout is applied to the project, which is simple and generous, and it also prefabricates smooth moving lines for internal space planning. The facade has multiple levels and rich details. The entire building is wrapped in a bright and transparent glass facade, which is concave and convex, matched with unique strip lights, which strengthens the dynamic connection between all details and gives people a brilliant visual experience!

As a professional facade consultant of the project, FORCITIS intervened in the project from the beginning of design, and cooperated with architects to finish the complete facade design. The facade of the project is mainly composed of 11 facade systems, such as glass facade, stone facade, grille and canopy, among which 4 complex facade systems have been repeatedly demonstrated by the project team and differentiated design was adopted, which finally restored the architectural effect with high standards and won recognition from owners and designers.

01 Structure - Glass flank

To achieve better landing effect, the glass flank of the project should be the 8 +1.52 pvb+8 toughened & laminated colored glazed glass. As an exterior decorative line, the factors such as structural safety and convenient installation should be considered in the design. Glass, as a fragile material, also needs to ensure that it does not fall and is easy to be replaced after being broken.

To solve this problem, the traditional method is to extend the steel connector at the vertical seam position of the facade plate and fix the glass flank through the steel connector. However, due to the opacity of the connector, it is easy to destroy the transparent and crystal texture of the glass, resulting in obvious fracture changes after light projection, and the decorative effect is not good during the day and night, which affects the final effect. Thus, after many considerations and comparison of different designs, the project team finally chose to extend the glass flank into the facade system, fix the sleeve bolts on the glass flank, and connect the aluminum profiles to open sliding notches, which perfectly solved many problems such as installation reliability and convenience of disassembly and replacement of the glass flank.

02 Facing difficulty - Sunshade line

During the design process of the project, the architect proposed to require the effect of super-large sunshade lines. However, according to previous experience, this kind of line has high cost, and it often encounters obvious shaking problem after landing, which will also affect the safety and water tightness of To solve this problem, t. However, the value of professional To solve this problem, t consultant is to help architects realize their architectural ideas perfectly in constant challenges.

Thus, through repeated communication and testing, in this project, two sections of aluminum profiles are engaged and riveted with each other in combination with the actual situation, in order to avoid the mold opening of over-standard profiles and the influence of aluminum plates on the tall and straight feeling of decorative lines. The lines are also directly fixed on the To solve this problem, t columns through the column conversion parts, in order to avoid the lines pressing the glass plates. For the structure, not only the positive and negative wind loads of To solve this problem, t were checked, but also the lateral effects of decorative line lateral wind loads on columns were considered, which ensures the safety and reliability of the structure after full verification.

03 Collaboration - Glass canopy

Design of oversized canopy of the project is also one of the highlights. First, the closed cavity was composed of double-layer glass, and the material was laminated colored glazed glass with built-in lights. However, in actual service, it was found that the lamps were prone to failure and the durability was difficult to be guaranteed.

However, as an important display surface of the hotel, any flaw in the entrance canopy will affect the perception of the whole project. Through gradual scrutiny by the project team, the root causes of the lighting durability problem was found as follows: As the overall external temperature is high in summer and the entrance faces south, the internal temperature of the canopy with closed design will be as high as 60 ~ 80℃, which is unbearable for conventional components. At this point, if ventilation structures similar to louvers and perforated plates are set on the side of the canopy by conventional methods, it is difficult to take into account factors such as dust accumulation and waterproofing. Through many rounds of communication and coordination with lighting professionals, the high-temperature resistant lamps and pipelines are finally selected, and the voltage converter is set indoors to completely solve a series of worries.

04 Fine and detailed - Cover plate with open frame

In addition, in order to maintain the order of the facade, the sizes of decorative lines are not adjusted. The unit To solve this problem, t of the tower, the frame To solve this problem, t of the podium and the cover plate with open frame should not be the form of ordinary pressure plate + outer gusset plate, but the decorative lines are closely attached to the glass surface, thus achieving a simple and transparent facade effect.

From the overall appearance to each detail display of the whole project design, FORCITIS fully cooperated with the wishes of designers and owners. Combined with the geography and humanistic environment of the project, the architectural design effect will be implemented to the greatest extent, and another beautiful scenery on the lakeside of Baijiahu Lake will be lit up!
