Located on a five-acre site at the south end of the downtown waterfront in Halifax, Nova Scotia, the Nova Scotia Power Office Facility has incorporated strategies in design and construction, demonstrating leadership in energy construction design in the province. The facility will house over 500 employees in approximately 18,000 gross m2.

Seawater from the Halifax harbour is piped into the new building and is delivered to 12 Kubes that convert low temperature water to a usable higher temperature source for heating the building. This same system also provides cooling and air conditioning for the structure.

Nova Scotia Power has adopted the LEED (Leadership in Energy and Environmental Design) green build rating system. NS Power Headquarters is a LEED-NC Platinum Candidate, the highest level of the premier green building rating systems. NSPI is expected to achieve 54 LEED points. This will be the first LEED Platinum certified building in Nova Scotia and in the Maritimes as a whole.
