Cannon House Office Building Renewal

Cannon House Office Building Renewal

House Office Building: Washington, DC

The comprehensive infrastructure upgrade and total renewal of this 826,500-SF congressional office building balanced historic preservation efforts with incorporating state-of-the-art systems and workplace standards.

Major systems addressed by the modernization included HVAC, plumbing, lighting, power distribution, life safety, fire protection, building automation, and communications.  System improvements were designed in accordance with federal energy consumption regulations and accessibility requirements. The building modernization will also comply with applicable codes, standards and guidelines while enhancing safety and security, increasing adaptability and flexibility, integrating cutting edge technology, and reducing energy consumption.

Design for Phase Zero was completed in December 2014. Phase Zero included building utility infrastructure renewal, as well as planning for the subsequent renovation of programmatic spaces. Design provided for uninterrupted utility support during construction Phases One through Four in the occupied building. New utility infrastructure was carefully orchestrated to dovetail with available building pathways and existing building systems, minimizing disruption to occupants.

Design for Phases One through Four was completed in December 2015. These phases of construction will include replacement of distribution systems throughout the facility. Modern high-performance systems have been designed within the context of the building’s historic fabric. For example, historic luminaires will be relit with LED light sources, and HVAC and plumbing distribution systems will be integrated within existing pathways, preserving the volume and historic finishes of occupied spaces.
