Sumit Singhal loves modern architecture. He comes from a family of builders who have built more than 20 projects in the last ten years near Delhi in India. He has recently started writing about the architectural projects that catch his imagination. BinhaiXiaowai High School in Tianjin, China by HHD_FUNOctober 1st, 2015 by Sumit Singhal
Article source: HHD_FUN BinhaiXiaowai High School is located in Sino-Singapore Tianjin Eco-City, a low energy consumption high schoolwith 36 standard classes and National Green Building Label-3 rated. Since the site area is limited, the architect tried to compactly position various functionalities in order to save space. On the north side of the site is the multi-use building, including classrooms, laboratories, offices, libraries, presentation rooms, dining halls, exhibition halls, parking space for bikes, and etc.  Image Courtesy © Wang zhenfei

As a National Green Building Label-3 rated architecture, the application of energy saving materials and energy saving infrastructuresis indispensible, including the high efficiency external structure, high performance air conditioning sets, smoke extractors, water pumps, elevators, intelligent lighting system, energy recycling ventilation system, use of renewable energy, rainwater harvesting and purification system, usage ofuntraditional sources, and recycling varieties of new typesof materials.

All of the standard classrooms are positioned on and above the second floor and south facing, with window/floor area rate averaging over 20%, ensuring interior lighting. Atriums are installed in courtyard in the multi-use building, leading in natural lighting, and increases natural lighting in the corridor’s space, making it possible for the classroom to receive sunlight from both sides, creating ahealthy and comfortable interior light environment for students. The north side is positioned with small size classrooms and auxiliary roomsto maximize the use of space. The office area is positioned between two teaching areas, convenient for teachers to commute between offices and classrooms. The laboratories are situated at the north end of multi-use building, connectedwith the teaching area in parallel, convenient for teachers and students to commute in between.

In the winter, it’s able to avoid the prevailing wind to minimize heat lost. From simulations of outdoor wind environment, this project’s maximum wind speed in pedestrian area is 3.29m/s, the maximum wind speed amplificationis 1.00; this project is maintaining a pressure difference above 75% in the front and back of the building during summer and transitory seasons, in order to avoid vortices and blind angles in partial areas, ensuring interior natural ventilation during these seasons by keeping open windows and interior doors.

The sunken plaza brings natural lighting to the lower level. The zigzagged shape of the architecture encompassed two plaza spaces, on the front and rear, the frontplaza as the entrance plaza, for traffic and evacuation, the lower level under the plaza is bike storage spaces, and light pipes are leading in natural lighting to the underground space, providing lighting for the garage. The rear plaza is also the roof platform for presentation rooms, providing students outdoor activity spaces.

The southwest side of the site is dormitory building, with five levels above ground and one level of basement underground, including roofed playground and 25 meters short course swimming pool, offering students a place to exercise without having to exit the dormitories, and unaffected by the weather. In order to save the usage of land, the roof of roofed playground is designed to a basketball field, directly reachable from the dormitory building. South end of the dormitories is designed together with the stadium’s grandstand, increasing volume and saving usage of land. The school is equipped with 400m standard track and international standard soccer field, the lower underground parking lot isable to accommodate an approximate of 500 vehicles, open for the community, in hope to alleviate parking congestion in the community.

HHD_FUN are cooperating with people from all walks of life, such as artists, fashion designers, mathematicians and engineers etc. They are exploring the new design possibilities by means of this cross-over cooperation.
