Note: While great efforts have been taken to provide accurate and complete information on the pages of CPEP, please be aware that the information contained herewith is considered a work in progress for this thesis project. Modifications and changes related to the original building designs and construction methodologies for this senior thesis project are solely the interpretation of Jonathan Fisher.  Changes and discrepancies in no way imply that the original design contained errors or was flawed. Differing assumptions, code references, requirements, and methodologies have been incorporated into this thesis project; therefore, investigation results may vary from the original design.

General building Data


Building Name: Westinghouse Building 4

Location: Cranberry, PA in the Cranberry Woods Office Complex

Building Occupant Name: Westinghouse Electric Company

Size: 120,000 sq.ft.

Stories: 3 above grade, 4 levels total

Owner: The Ferchill  Group, Chicago IL (

General Contractor: Turner Construction (

Dates of Construction: Aug. 2009 to Nov. 2010

Cost: Approx. $25 million

Delivery Method: Design-Bid-Build

Architecture: For the architectural and functional components of the building the goal was simple; maximize open floor space for cubicles and allow as much                                  natural light into the building as possible.  The building exterior is also meant to mimic, but not be identical to Westinghouse’s 3 other                                   buildings on the same property.  The building was constructed using the IBC 2003 manual for specifications and requirements.  The zoning                                   requirements for this building had to follow the Cranberry Township Non-Residential Building and Zoning Package, which can be found at                                   the following website,  This document provides all of the Township’s                                     requirements, regulations, and applications for a building of this magnitude and purpose.  There are no historical requirements or effects                                   that go along with this building or the site on which it was built

Facades and Roofing: The façade of the Westinghouse Building 4 will consist of 3 different materials; brick, polished aluminum, and glass.  The brick and                                   aluminum facades alternate levels as you go up the building.  The brick is red brick that adheres to ASTM C 216 standards and has a grade                                   of MW or SW.  The compressive strength of these bricks is to be 4400 psi, the absorption will be less than 30 g/30 sq in. per minute, they                                   will be rated “not effloresced”, and shall be manufactured by Watsontown Brick Company.  The polished aluminum sections will be made                                   of a tempered aluminum alloy metal and reinforced with steel.   The panels will have a high-performance organic finish applied to them.                                    The color and gloss will be Dark Grey PPG Duranar Exotic Coating as was selected by the architect.  This aluminum curtain wall will have                                   tolerances of 1/8” from plumb in 10 ft and ¼” from plumb in 40 ft.  The last part of the building façade is the window system of the                                         building.  The window system has aluminum framing that matches the color and specifications of the aluminum curtain wall system.  The                                   main building façade windows will be made of PPG Industries, Inc. ¼” thick Sputter-Coated Float Glass.  This type of glass is tempered                                   and heat treated for maximum hardness and break resistance.  It will be coated with metallic-oxide or metallic-nitride coatings, which will                                   give them their physical properties; Solar Heat Gain Coefficient: .31, Shading Coefficient: .36, U-value: .28 average, and Visible Light                                   Transmittance: .51.  The roofing of the building is to be a Thermoplastic Polyolefin Roofing Membrane.  The membrane will be fabric                                   reinforced and .015 in thick.  The exposed face color will be white and the material will have a 225 lbf breaking strength. 

Sustainability: The windows of the building are the only real sustainability feature of the building.  The windows are very large and let in the majority of the                                   light required by the office inhabitants.  This cuts down on lighting costs and studies have shown that natural light improves workers work                                   ethic and productivity.
