Capital One Financial Corporation Headquarters

Capital One Financial Corporation (CapOne) consolidated its Northern Virginia operations onto a new corporate headquarters campus consisting of approximately 1.1 million square feet. Integral Group was commissioned to assist Capital One in the selection of an appropriate site and subsequent architectural and MEP engineering design services for the headquarters building.

The occupancy of the campus was phased over a five-year period with the first phase consisting of 500,000 ft². The initial phase of this project was fast-track with occupancy by the third quarter of 2001. A chilled water central plant located in the basement and roof mounted cooling towers serves chilled water air handling units on each floor supplying overhead VAV systems on floors 1 & 2 and underfloor air systems on floors 3 – 14. Hot water heat is provided to make up air units and air handling units for floors 1 & 2. Floors 3 -14 are provided with electric heat at the perimeter terminal units.

The electrical service consists of two 4,000 amp switchboards. An 800 KW diesel generator serves life safety loads. A 1,750 KW generator and 750 KVA UPS provide power to critical loads including the data center, data closets, the executive floor and critical HVAC systems. Lighting in typical office areas is provided by indirect fixtures with a networked lighting control system allowing individual user control of lighting levels.
