DPR并没有建造新的，而是选择翻新一个空置七年以上的20,000平方英尺的空间。该空间旨在实现零净能源使用，并结合了许多可持续性元素以及数据驱动的决策，以创建DPR所谓的“活实验室”，以展示技术，产品和系统。
The building uses traditional fan-powered terminal units and radiant sails that allow the space to simultaneously heat and cool in various areas of the office.
整个内部由24个单元照亮，使大量的自然日光进入，而全天几乎没有能量。LED照明系统与自动传感器系统结合使用，整天提供一致的照明水平，同时最大程度地节省了能源。
The 141-kW photovoltaic system is designed to provide 10% more energy than required to achieve a net-zero energy certification. The Sun Power Helix photovoltaic system is one of the first of its kind on the East Coast, according to DPR.
The building also features a dashboard that provides real-time energy and water consumption data as well as energy produced by the photovoltaic array.
The team installed four different finished concrete options to see what each would cost, look like and hold up under normal office wear and tear. DPR carpenters installed reclaimed wood taken from barns in Connecticut and the Maryland Eastern Shore.
The team incorporated concepts of the WELL Building Standard across the project, including healthy food options and access to a fitness center.
Early collaboration was required on the job among the design-build team members. DPR used its dual role as owner and general contractor to its benefit. It says it gleaned a better understanding of the impacts of all decisions and the effects on cost, schedule and quality. The company adds, however, that handling the general contractor and owner roles also was a challenge because its deep involvement with the project gave it a heightened interest in working as a team with the architect and engineers so that changes during construction could be implemented while maintaining schedule, cost and quality.
