In the heart of midtown Harrisburg, Pennsylvania, the LEED Gold certified Campus Square building shines as an example of urban revitalization and a commitment to sustainable design and construction methods. The area was transformed from an urban brownfield site with nine contaminated underground storage tanks into one of the greenest buildings in central Pennsylvania. The four-story building provides retail, meeting, and classroom spaces across the street from the midtown campus of Harrisburg Area Community College (HACC).

What We Did

As part of a design-build team, Gannett Fleming provided architectural, mechanical, and electrical fit-out design services for the facility, as well geotechnical design and construction administration services. The interior plan features repeated vertical stack elements and maximizes the placement of office and retail space on the perimeter. This layout enables natural daylight to penetrate the spaces while simplifying the supply and return of mechanical operations and energy resources. The building exterior consists of brick accent masonry and a glass curtain wall, which was designed to blend well with the surrounding historic district.

Key Features

  • 9,000-square-foot first floor houses the Green Center of Central Pennsylvania
  • 18,000-square-foot upper floor houses administration offices and classrooms for HACC
  • Geothermal HVAC system features 46 wells that are 400 feet under the building’s footprint.

Sustainability Features & Outcomes

  • Green initiatives and systems reduce owner energy costs by half
  • White roof reduces heat island effect
  • Rooftop 42-kW photovoltaic system serves as primary source of electricity for common areas
  • Geothermal HVAC systems reduce energy costs and eliminate need for extensive mechanical rooms and rooftop equipment 
  • Vegetated roof above main entrance reduces stormwater runoff
  • Recycled 98 percent of construction waste locally
  • Reduced annual water consumption by 51 percent.
