GENERAL BUILDING DATA:
Table 1: Building Information
Table 2: Project Team
The URBN Center is a renovation of the famous design of Robert Venturi that is aimed to bring students of the Antoinette Westphal College of Media Arts & design in Drexel University under one roof. The four story building is re-designed to create a great working environment for students who are pusuing an education in Architecture, Arts Administration, Design & Merchandising, Digital Media, Entertainment & Arts Management, Fashion Design, Game Art & Production, Graphic Design, Interior Design, Music Industry, Product Design, and Web Development & Interaction.
It is important to point out that although the URBN Center is a four story building, it is divided into 8 levels (two levels on each story). When entering the building, the visitor will be welcomed with a large lobby that is used to display students’ work and to host merchandising spaces for the students and guests. A stairwell is located in the center of the first story that extends all the way to the fourth story linking all 8 levels of the building. Throughout the eight levels of the URBN Center, the space is divided for students’ studios, classrooms, display galleries, computer labs, a screening room, and faculty offices.
Additional architectural features of the URBN Center include sliding walls that are designed to allow the students to creatively change the work space they are in. The building also has a skylight above the stairwell that allows a lot of natural lighting inside the building. As for the Annex, it will feature a black box theater and a state of the art screening room. Figure 1 shows 3D sections throughout the four stories of the URBN Center.
Due to the historical significance of Venturi’s original design, there is some preservation of certain aspects of the design that were untouched during the renovation. For example, there was full preservation of the façade along the south side of the building which features a classic mosaic design by Robert Venturi. A picture of the preserved façade is shown in figure 2. Also, there are various art designs on several walls of the original design that were preserved due to their historical importance.

As mentioned above, the south side of the building maintained its original façade that was designed by Venturi. The south exterior façade is composed of a mosaic exterior design that is shown in figure 2. A new square brick veneer façade is placed on 6” CMU with 1 3/8” air cavity on the other 3 sides of the URBN. The south Side shows typical window Ribbons that are similarly installed on the west elevation. As for the North and East elevations, they feature curtain walls that are both decorative and sustainable by allowing natural light inside the building. The glass that is used on the windows and the curtain walls of the URBN Center is a ½” thick clear tempered glass. There is also a Storefront at lobby and entry vestibule is an aluminum system with tinted insulated glass units. The same materials are being used for the Annex façade and windows.
As for the roofing of the building, both the URBN center and Annex have a mechanically fastened / adhered (to manufacturer’s recommendations) EPDM system: Centimark 60 45 mil EPDM, black face finish.

Natural lighting is a major part of the sustainable efforts in the URBN Center. This is achieved by a skylight on the main roof of the building as well as long window ribbons and curtain walls along the north and east elevations. Also, the building utilizes a chilled beam system which is widely considered as a more economical HVAC system in the long run. A more detailed analysis of this chilled beam system is going to be in the next project submittal.
BUILDING STATISTICS PART 2
Structural Steel Frame:
Figure 3: Raised Levels Supportsthe new levels.
The original design of the URBN Center consisted of 4 levels. However the renovated consists of stepped floor which sums up with a total of 8 levels (2 levels on each story). Therefore, most of the new modification of the framing system took place when constructing the new levels. The new framing consists of cold-formed metal framing. On a typical raised level, a 4SWIB Brace is placed at every other bay for floor support. A detailed of the new floor brace support is shown in figure 1. Also, a 4x4x5/16 Brace @ each vertical channel is used for support of a typical operable partition. Composite slabs are placed on certain sections of the new levels. The composite slab consists of 2 ½” normal weight concrete cover w/ 6x6-W2.0 x W2.0 WWF OVER 2" 18 Ga. (GALV.) COMPOSITE DECK. (4 1/2" TOTAL THICKNESS).
