201 Rouse Boulevard

Architecture

Overview

201 Rouse Boulevard is a high-end high performance building being erected at the Navy Yard in Philadelphia, PA. With a glass walled ground floor pedestal and copious windows wrappings, the building will glow with natural light and be a radiating beacon at night. The top three floors, primarily office space, will have an exotic zinc clad facade punctuated with floor to ceiling windows, giving stunning views of the navy yard the Philadelphia skyline to the occupants. The lobby, which houses a health cafe and fitness center, is enriched with wood flooring, Jerusalem limestone and Venetian plaster. The ground floor pedestal also plays as the main architectural feature of the predominantly rectangular office building. Those features being a 8 ft cantilever of the office spaces over the main entrances and a curved glass facade on the south-west side of the building.

Building Enclosure

Facades

201 Rouse Boulevard has two primary facade types, the top three office floors and the ground floor pedestal. The ground floor pedestal’s facade is composed of three components: floor to ceiling glass “store-front” panels with aluminium mountings and mullions, full length brushed aluminum panels, and to “weigh” down this light and airy facade, the building uses light textured terrazzo paneling. The top three office space floors are a different story, though they do keep the vertical lines created by the base window panels, and have large arrays of windows. These large floor to ceiling windows come in four types to match the four patterns of the primary facade system. The primary system is consisted of four repeating patterns of exotic zinc cladding punctuated by vertically rising aluminum fins, which serve a small additional part in sun shading. The building’s design used these zinc facade elements to hide almost all structural elements.

Roofing

201 Rouse Boulevard has a standard asphalt covered insulation (Min R value of 38) on steel deck roof. The roof slopes (¼”/1’) to the center of the building where the drains and mechanical equipment are. To help obfuscate the rooftop mechanical systems there is a 13 ft. high mechanical screen setback 15-25 ft from the parapet.

Sustainability

The project at 201 Rouse Boulevard is to be LEED Certified under Core and Shell (v2009). To achieve this LEED rating, the project is relying upon modern lighting systems with ample daylighting, an efficient economized-cooling Variable-Air Volume HVAC system, and its location and support of local amenities and transportation. Additional sustainability measures to be added development of LEED and Landscaping plans.

Primary Engineering Systems

Construction

Turner Construction is leading the construction, which broke ground on October 21st 2013, of 201 Rouse at the Navy Yard Corporate Center. The project, costing upwards of $25 million, is one of a series of design build projects designed and developed by DIGSAU and Turner for Liberty Property Trust at the Navy yard Corporate Center; these project advanced rapidly via the usage of similar project teams for multiple projects. 201 Rouse is slated to be fully constructed in Q1 of 2015.

Lighting

The occupied areas of 201 Rouse are fit with modern ceiling hung single T5 Lamp fixtures, while the utility areas are fit with standard dual T5 fluorescent fixtures. 201 Rouse has an exterior that is over 40% windows, to take advantage of this abundant daylight there are several photocells to provide daylighting control to the building automation systems. The exterior of the building is lit with recessed can lights, illuminating paths and occupied exterior areas. The 100+ parking lot is lite by single or dual downward facing halogen lamps, while the landscaped areas of the site are illuminated by round diffuse halogen light posts.

Electrical

Two 600 Amp 3 phase electrical service line connect 201 Rouse’s 1500 3 Phase wye transformer to the local utility grid, with service provided by PECO. A main panel board of 2000 Amps is located in the electrical room of the main floor; an 800 amp bus distributes electricity to electrical rooms on the upper three floors. Each of these floors have their own high density panels and 75 kVA step down transformers to 120/208 V. The main distribution panel handles the emergency equipment. Through an automatic transfer switch additionally connected to a 30kW outdoor generator the system provides continuous emergency power to two life support panels (one at 120/208 after a 9kVA step down transformer). posts.

Mechanical

201 Rouse Boulevard’s heating and cooling is provided via three rooftop packaged units in conjunction with 4 electric unit heaters (used at entrances and equipment spaces). The building’s primary spaces are conditioned by two large 33,600 SCFM (standard cubic feet per min.) rooftop air handling units (AHUs) with variable frequency drives (VFDs) that provide up to 1,500 kBTU/hr cooling and 750 kBTU/hr heating each. To achieve greater control and more efficiency, 201 Rouse utilizes a economizer system with the return air and single duct Variable Air Volume (VAV) Terminals of four varying sizes, all with electric reheat coils, to properly condition different zones. The system has a minimum outdoor intake of 16,805 SCFMs (24%) providing adequate ventilation according to ASHRAE Standard 62.1. Additional exhaust for bathrooms, utility areas, and stairwells is provided by dual rooftop units and local transfer fans. The primary space AHUs have four scheduling modes: occupied, unoccupied, morning warm-up, and morning cool-down. When in occupied modes, the control sequence maintains a minimum outside air flow (set by ASHRAE 62.1), manages the variable volume control of the supply and return fans using system air balancing, uses stepped electric resistance heating to maintain the temperature setpoint, and utilizes economizer cooling when the outdoor air enthalpy is lower than the return air enthalpy. When in unoccupied mode, the outside air dampers are closed and the AHUs cycle to maintain the discharge air temperature setpoints.

Structural

The superstructure of 201 Rouse is structural steel, a substructure of poured concrete, and slab on metal deck floors. The foundation of the building is a wooden pile and concrete cap foundation system, with piles and cap for each column of the superstructure. With no basement, the foundation of 210 Rouse utilizes a 2 foot footing for the exterior walls, and a slab on grade for the floor. The superstructure of the building consists of steel columns, ranging W14X120 to W12X40, beams (typically W21X44 exterior and W24X62 interior), girders(W16X36 and larger), and joist girders (typically 30k7). Typical floor construction is 3”x20 gage galvanized type B composite deck topped with 2 ½” normal weight reinforced concrete (compressive strength of 3500 psi at 28 days).

Secondary Engineering Systems

Fire Protection

201 Rouse is a fully sprinklered (per IBC Table 601) business class building. All exterior load bearing walls and stair/shaft enclosures have a 2 hour fire rating and the building occupants have a max exit access travel distance of 300 feet (fully sprinklered). In the tenant spaces the sprinkler system is spaced in a 12 x14’ grid and is feed by two independent standpipes with a rate of 0.10/1500 GPM/sqft. The utility and mechanical spaces of the building are also sprinkler protected with 0.15/1500 GPM/sqft.

Transportation

Within the building there are two hydraulic elevators that are publicly available and service every floor. On the building site there will be ~150 automobile parking spots along with racks for bicycle storage. 201 Rouse is in close proximity to a campus shuttle, Southeastern Pennsylvania Transportation Authority (SEPTA) bus and subway stations. posts.

Telecommunications

201 Rouse has telephone and networking connections through the local utilities and is distributed throughout the building from the first floor’s electrical room. The building’s security system includes magnetic swipe readers for two of the building’s entrances and camera equipment covering the lobby and elevator bank; all controlled/recorded with equipment in the first floor electrical room. Additional security to be provided as per tenant fit out.

Special Systems

201 Rouse has no non-standard building systems, though that may change as the tenant fit out is specified.
