HOUSTON — WorleyParsons Group has signed a long-term lease for 141,000 square feet at Energy Center II, a 12-story, 305,000-square-foot, Class A office building located in Houston. The company will occupy the top five floors of the building, as well as have a reception area and conference facilities on the ground floor. The space will be used as the company’s U.S. corporate headquarters and for the consolidation of its Houston upstream oil and gas operations.

It sits adjacent to Energy Center I, the first phase of the project that was completed in January 2008. Energy Center I is presently the largest speculative office building in Houston to receive LEED-Silver certification.
