Every year in early September, as graduate students at the Southern California Institute of Architecture (SCI-Arc) in Los Angeles put the finishing touches on their thesis projects, a Sci-Arc faculty member and students prepare a temporary pavilion for the annual graduation ceremony. This year, faculty members Dwayne Oyler and Jenny Wu of Oyler Wu Collaborative, along with their students, designed a pavilion entitled Netscape for the event that stretches across the northern end of the SCI-Arc parking lot, providing seating for 900. Consisting of 45,000 linear feet of knitted rope, 6000 linear feet of tube steel, and 3000 square feet of fabric shade louvers, the pavilion creates a sail-like canopy of rope and fabric that floats above the audience. With its fabric louvers tilted toward the western sky, the canopy is designed to provide shade for the specific date and time.
Netscape utilizes a double layer of netting in varying configurations to create a three-dimensional field of billowing shade louvers. Based on a conventional knitting technique, like that used in the making of a sweater, the pavilion exploits the malleability of this technique as it stretches to conform to the three-dimensional shape of the structure. Unlike a conventional net, the knitting technique is not fixed at its intersections, allowing the shape of the nets (and their grids) to contort both at the upper and the lower surface. With the nets contorting differently, the shade louvers that are stretched between them become a dynamic field of fabric, twisting and bending in order to span across the space in between. Design of the project involved an elaborate back and forth between digital and analog systems of investigation. With engineering done by Nous Engineering, analysis of the tension in the nets provided constant feedback that informed the shape and three-dimensionality of the structure, as well as some basic form-finding for the nets. As the project progressed, however, large three-dimensional models provided a means of studying the behavior of the grids and their resulting geometries.
With the shade louvers designed to block the setting sun in the west, the view from inside the pavilion offers a dramatically different experience. The three-dimensionality of the double-layered netting reaches depths of about 10’, and becomes open and porous when facing eastward into the complex three-dimensional field of fabric and rope.
在每年的九月，美国洛杉矶的南加州建筑学院（SCI-Arc）都会举行学生毕业典礼。SCI-Arc的老师和学生会为这一大典准备一个临时展馆。今年，SCI-Arc的老师Dwayne Oyler 和 Jenny Wu（来自Oyler Wu Collaborative）与学生合作，设计了这一展馆。展馆提供900个座位，穿越整个SCI-Arc的停车场并在其北端结束。使用了总长45000英尺的绳子，6000英尺的钢管以及总面积3000平方英尺的遮阳面料，创建出如同树冠般的绳索体系，让遮阳面料漂浮在观众上方，其遮阳面料向西倾斜，为毕业典礼提供阴影。

▲ (Left) Rope being knitted (Right) The steel structure as well as the nets were constructed/knitted on the ground and lifted into place. Once the structural canopy was lifted, the steel columns were attached and the net was was folded over to form the lower surface. The fabric louvers were then stretched between the two nets.
▲ Physical study models were used to investigate different knitting techniques as well as configuration strategies for the pavilion
▲ A large knitted model was used in the final stages of design to explore different strategies for placement of the shade louvers. The model was placed outside oriented properly to the sun in order to study the effectiveness of each louver.
