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 is balancing historic preservation efforts with incorporating state-of-the-art systems and workplace standards. The Program of Requirements (POR) and design phases are complete and phased construction is underway, scheduled for a 2024 completion. Early phases included building utility infrastructure renewal, and planning for subsequent renovation of programmatic spaces. Design provided for uninterrupted utility support during construction phases in the completely occupied and operational facility. New utility infrastructure was carefully orchestrated to dovetail with available building pathways and existing building systems, minimizing disruption to occupants.

Construction involves 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. Major systems addressed by the modernization include HVAC, plumbing, lighting, power distribution, life safety, fire protection, building automation, and communications.  HVAC and plumbing distribution systems integrate within existing pathways, preserving the volume and historic finishes of occupied space.

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.
