This new office building uses various sustainable design strategies to increase the building envelope's efficiency and to reduce energy usage. Recycled and recyclable materials are used on the building's skin and it's interiors. The site was effectively a brownfield site.

WKL developed a life cycle costing analysis on energy savings for 5 design strategies: high performance glazing, fixed sun-shading, solar collectors, directed day lighting compared to a uniform baseline window arrangement, and a light-colored roofing membrane.

The quantitative data earned the project a 50,000 dollar grant from the Sustainable Energy Fund of Central Eastern Pennsylvania in 2008.
