The Evangelical Press Building opened in Harrisburg, Pennsylvania in 1918.  It was designed by architect Frank Gordon Fahnestock and Engineer  John A. Raidabaugh.  The publishing plant underwent two expansions in the 1940’s and then became a state office and laboratory in the 70’s.  In 2005, GreenWorks Development acquired the then vacant building, and transformed it into a modern academic space, serving Harrisburg Area Community College (HACC).  The seventeen million dollar renovation successfully maintained the building’s historical aspects, while updating the interior and exterior to accommodate the 2,500 trade and technology programs students.

	The Evangelical Press Building has a typical exterior wall composed of a 12” masonry/brick veneer with 2” rigid insulation and 5/8” Gypsum Wallboard (GWB).  In addition, an aluminum curtain wall system with 1” insulated glazing supports the large atrium entrance.

The roof consists of a single-ply membrane system, 2” insulation, and concrete slab.

	The Evangelical Press Building has applied for LEED certification.  It has attempted 32 out of 69 possible design and construction credits.  The majority of these credits come from the “Energy & Atmosphere” and “Indoor Environmental Quality” sections of the LEED checklist.
	The most visual elements of sustainability include skylights and an atrium which provide natural daylight, shading to deter heat gain, and the effort to maintain existing walls, floors, and roof.





Building Statistics - Part Two.

The $17 million Evangelical Press Building renovation took a little over one year.  GreenWorks Development and Wohlsen Construction led the project, selecting McClure Company and G.R. Sponaugle to tackle the mechanical and electrical design-build.  The other scope of work was carried out in a traditional design-bid-build fashion.  The building underwent façade restoration, interior and exterior renovation, and various civil and landscaping adjustments.  However, The Evangelical Press Building was worked on twice before — the third story was added in1941 and a lateral addition extending north was added in 1946.  Presently, it encompasses 130,000 square feet of academic space, and is a proud contributor to the midtown revitalization plans of Harrisburg, Pennsylvania.

PPL Electric Utilities Corporation services the Evangelical Press Building.  A PPL Electric pad mounted transformer feeds the main switchboard and panelboard with a 3 phase, 4 wire, 277/480 volt system.  3 phase, 4 wire 120/208 volt systems are also utilized to service other panelboards.  Distribution is handled through two power bus ducts at 1,200 amps each.  Several transformers are incorporated into the electrical design, ranging from 15 to 75 kVA.  A 100KW natural gas generator is also present.

Fluorescent lamps light up classrooms, offices, and computer labs throughout the building.  The food court area is illuminated by modern, pendant mounted lighting fixtures.  The Evangelical Press Building classifies as a School/University, which has a maximum LPD of 1.2 W/ft2, according to ASHRAE Standard 90.1-2007 .  Several spaces, including a traditional classroom, library, and trade classroom, had calculated lighting densities of 1.0W/ft2 or less.  There are a few exterior lighting fixtures that take advantage of a concrete base to withstand outdoor conditions. 

The 130,000 ft2 Evangelical Press Building is served by four-pipe variable air volume (VAV) air handling units (AHUs).  There are three indoor AHUs and one rooftop AHU.  

Two of the indoor AHUs (1 & 2) are located on the third floor, and serve the 1st, 2nd and 3rd floors of the original “main building.”

The other indoor AHU (4) serves the basement of the main building, and is located there.  It’s coupled with an indoor energy recovery ventilator (ERV), which tempers the outside air (OA) required for the basement.  The ERV uses the exhaust air (EA) from the main building toilet and storage areas to perform its heat exchange.

The single rooftop AHU (3) serves the basement, 1st and 2nd floors of the “annex building.” 

Two natural gas fired sectional boilers generate hot water at 180°F, which is distributed to the AHU preheat coils, shut-off VAV box reheat coils, and miscellaneous terminal heating equipment.  The boilers are sized to accommodate 67% of the peak heating demand, and are located on the third floor.

There are two rooftop chillers, which are air-cooled. The smaller chiller, sized at 110 tons, is designed to handle the fall, winter and spring cooling loads.  When that chiller’s capacity is exceeded, it will shut down and the 210 ton chiller will kick in, which is sized to handle the more extreme summer cooling loads.  This was designed with maximum operating efficiency and reduced energy costs in mind.

A plenum return system handles the air distribution.  The majority of spaces have a ducted transfer to the adjacent corridor ceiling, which acts as the main return plenum. 

A 16” concrete slab foundation has certainly stood the test of time. It supports the three story, steel reinforced concrete structure.  The renovation has greatly improved the 26” horizontal and vertical beam system, which now boasts exposed columns bearing original capitals.  The building façade is composed of a 12” masonry/brick veneer with 2” rigid insulation and 5/8” Gypsum Wallboard (GWB).  In addition, an aluminum curtain wall system with 1” insulated glazing supports the large atrium.  All of that is topped with a single-ply roofing membrane system, which covers the 2” insulation and concrete slab.

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 Kayla Gavin. 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.
