BUCEA New Campus Student Comprehensive Service Building

The building located on Daxing Campus of Beijing University of Civil Engineering and Architecture (BUCEA) is a small-scale public building. The major problem was the change in functions. The building would be used as the auxiliary commercial facilities for the dwelling area in the early period of campus construction and converted into a multi-function building upon substantial completion of the campus. In this regard, different assumptions were proposed: multi-function hall, exhibition hall, activity center, indoor gym etc.. For this, we took the free conversion of functions as the starting point for the design concept and formulated the following design keynotes: 1st floor: column-free; combination with unit modules; favorable conditions for functional conversion by electrics and equipment; easy-to-remove and recyclable materials for the internal interlayer; addition of energy-saving and environmental-friendly facilities. According to the design keynotes, we proposed a square plane of 60m×60m arranged with 10m×10m, while each unit is composed of one central skylight and four-slope roof. Based on the above, in combination with the energy-efficient requirements, several important measures were proposed before the current model was eventually formed. Measure 1: since it was a single-storey building, the insulating layer for the roof was a hard nut. For this, on the four-slope roof, we designed one additional concrete layer of a reversed four-slope roof as well as hid the beam of 2m high between the two roofs. Measure 2: the central skylight was opened for ventilation. Measure 3: one verandah was arranged outside the building to shelter the exterior windows as well as provide a semi-exterior space for shops and activities of students. The verandah also functioned as a support for the large-span beam. To enrich the exterior elevation, the verandah was treated to cut off the exterior units upon rotating the axial net. The building is of a RCC structure. To express the geometric logic relation of the building, concrete was applied on the roof and cut surface, while the wooden exterior wall was used inside the cut.
