The Siemens Westinghouse Fuel Cell Facility exemplifies Pittsburgh's efforts at remediation of land where steel mills once stood. Siemens' decision to manufacture solid oxide fuel cells as a clean, sustainable energy source of the future, at a location so intrinsically tied to Pittsburgh's industrial past validates its commitment to progress.

From the early stages of the project, Siemens embraced the goals of achieving LEED® 2.0/2.1 Certification for the entire building, which includes a two-story office and one-story high-bay manufacturing area for a total of 190,000 square feet. Conference rooms, laboratories, cafeteria, restrooms and other support spaces are included in the office wing.

The combination of demand reduction, system efficiencies, and careful material selection, produce the total efficient life cycle and energy cost reductions in this building.

The hourly energy consumption for the building was modeled under two scenarios; a base case that indicated the energy performance to be in compliance with ASHRAE Standard 90.1-1999, and a low energy design to evaluate various green building strategies. The facility's efficient low energy design resulted in a total building energy consumption which is 52.7% lower than what an "energy efficient" building consumes in a year.

The perimeter walls are 8-inch precast concrete walls with insulation integral to each panel, and are considered as mass walls. The insulated precast wall panels achieve an effective u-value which is 5% more efficient than what is required. The largest energy saving feature of the building's skin is the vertical glazing system. The total glazing area is 19% of the gross wall area, and conducts 16% less heat than the required glazing.

The heating, ventilating, and air conditioning (HVAC) systems serving the building consist of a chilled water plant, hydronic hot water boiler plant, ten constant volume air handling units for air distribution and ventilation in the manufacturing area, and a variable air volume, roof top air handling unit serving the office and laboratory areas.

The rooftop unit uses heat recovery to enable high indoor air quality while minimizing energy usage. CO2 sensors monitor CO2 levels and adjust the ventilation air quantities accordingly. Air distribution in the manufacturing area delivers cooling directly to the occupied areas, increasing ventilation effectiveness while allowing hot air to stratify, dramatically reducing the cooling load.

Water conservation measures are in place with low flow and dry type plumbing fixtures, and efficient HVAC and cooling tower equipment. The overall consumption of potable water on this project is 31% less than a facility that is compliant with the Energy Policy Act of 1992, and overall wastewater generation is reduced by 39%.

Material resources have been conserved in several ways. Nearly all products and materials were manufactured within 500 miles of the project site. Half of the products and interior finishes were selected for their recycled material content. The cafeteria and several coffee areas have built-in recycling stations to support the recycling efforts of the employees. Construction waste was separated into various dumpsters and recycled by the contractor.

A project goal was to increase indoor environmental quality through careful selection of materials. Limiting or eliminating VOC emitting materials in adhesives, sealants, paints, carpet, and wood was specified and implemented. Windows on the south and east sides enable employees to have views to the outside and access to daylight, and optimizes worker productivity. Siemens has declared the building a nonsmoking facility enabling cleaner air quality and decreasing potential health risks.
