The Drexel campus straddles both sides of Market Street in Philadelphia’s University City section. Sasaki Associates' addition to the Daskalasis Athletic Center (DAC), a 1960s-era athletic complex, accomplishes several institutional and programmatic goals. It increases the university’s visual presence along Market Street, integrates existing and new buildings into a unified complex, and groups all of the recreation facilities into a new building wing. Respecting that the DAC is surrounded by one of Drexel’s few outdoor landscape spaces, the design also maximizes preservation of the site’s open space.
Drexel校区横跨费城大学城商业街两侧。Sasaki联合会对Daskalasis运动中心的扩建工程，一个20世纪60年代的运动综合体，完成了多项由来已久的主题项目。它提升了沿商业街的视觉感受，将新老建筑结合成一个统一的综合体，并将各种娱乐设施到新大楼的配楼中。考虑到DAC被Drexel的室外景观环绕，设计最大限度的保留了基地的开放空间。


The new building wraps around two sides of the DAC building, providing a new urban presence along Market Street. The main façade is treated as a large glazed screen with meandering folds shaded by the extension of the building’s floors. The folded enclosure provides alcoves along the exercise areas, where active users and equipment add a sense of colour and movement to the streetscape. The glazed skin is also the result of extensive energy studies.
新大楼包围着DAC大楼的两侧，带给沿商业街新的城市姿态。主立面由大面积带折叠的玻璃墙组成。折叠的圈地带给练习室封闭的空间，在这里使用者和各种器械为街景增添了色彩和活动。光滑的表皮带来宽阔的楼层。

The design is expected to reduce cooling loads by 50% on the south façade and 30% on the east. The building addition incorporates a major pedestrian artery, creating a walkway through the building linking two key areas of the campus. This newly created passageway renders existing and new programmes as a focal point for students, visitors, faculty and staff crossing the campus at this location.
设计准备减少南面墙体50%和西面墙体30%的冷负荷。大楼增加了一个主要的人行干道，创造了连接两个关键地区的通道。最新创造的走廊为当地校园的学生，参观者，职员和教工带来对新旧规划的聚焦。


The building’s largest component, an indoor gymnasium and jogging track, is placed on the upper portion of the site, opening up directly to the preserved green. The gym space, surrounded by open balconies, allows all activities spaces to be communicated visually. Ample fenestration around the gym provides day-lighting and visibility from inside and out, relating the interior space of the gym with the adjacent soft flooring plaza, used for outdoor group exercise.
大楼最大的组成元素，一个室内健身房和慢跑跑道位于基地的上层，直接面对外面绿色。健身空间阳台包围，这样可以使活动空间都能在视觉上形成交流。用于室外运动的健身房足量的开窗带来照明和室内外的能见度，将内部空间和邻近的底层广场相联系。


The plaza conceals a rainwater harvesting system that collects water from 50% of the existing DAC and 70% of the new structure into an underground cistern. Collected rain water is used for toilet flushing to reduce potable water demand. At street level, the building interacts with the passing urban scene. Paving patterns echo the angular folds of the building, a café is placed among trees preserved and integrated into the design, and a restaurant engages the larger community as well as students. A previously nondescript corner is brought to life through the combination of a landscaped plaza and the center’s climbing wall framed in glass - a further outward expression of a building housing dynamic activities.
广场隐藏了雨水收集系统，系统可以收集DAC50%和新结构70%的水分储存到地下蓄水池。收集来的雨水用于厕所从而减少饮用水的使用。在街道层，大楼和附带的城市背景相互影响。石块图案回应了大楼的尖角褶皱，一间咖啡厅建在树丛里，并与设计相融合，而餐厅也吸引着学生和社会市民。先前难以形容的角落通过景观广场和中心攀岩墙（一种未来建筑外表面的活动）焕发了生机。
