Cambria Hotel Washington DC Capitol Riverfront 82,000 square foot hotel with 154 guest rooms. It stands on Washington’s Capitol Riverfront, at the intersection of the Potomac and Anacostia rivers and scarcely a mile south of the Capitol.

The ambitious goals for this project aimed to sustainably redevelop an underutilized area and revitalize the urban ecosystem for the local community. Of the numerous sustainability features implemented, the project team prioritized strategies that would be beneficial to the project and building occupants in the long-term.

A strong focus revolved around resiliency. The team successfully achieved the Passive Survivability and Back-up Power innovation credit by incorporating generators and a rooftop photovoltaic system to support critical building operations in case of a power outage. The Triple Bottom Line pilot credit was also successfully achieved demonstrating the economic, social, and financial benefits of the LEED credits.

With growing interest around a building's carbon impact, the project team investigated the operational and embodied carbon of the building through an energy model and LCA analysis. Energy efficient systems and rooftop photovoltaic panels were incorporated to mitigate the operation carbon impact. And material optimizations were incorporated to reduce the embodied carbon impact.

 

Project Performance Data:

• Water: 34% Reduction, 954,000 annual gallons savings.
• Irrigation: No permanent irrigation system installed.
• Energy: 21% Cost Savings, 2,000,000 kBtu annual energy savings.
• Rooftop PV: 20,850 kWh anticipated annual energy generation to ensure passive survivability of the building in case of power outages.
• Waste: 76% (1,000 tons) diverted.
• LCA: 16% reduction in GWP, 333,000 kg CO2e savings.
• Site: The project is located in a Qualified Census Tract area. Additionally, a donation was provided to a local Land Trust in order to conserve existing natural areas.
• Parking: 92% reduction. Only 8 spaces were incorporated, 1 of which included an EV charging station.
• Bicycle Facilities: Long-term storage facilities incorporated for 18% of regular building occupants.
• Rainwater: Over 100% of rainwater runoff is retained for the 85th percentile storm event by utilizing permeable pavers, green roof, and bioretention facilities. Cambria on Q is a zero lot line project and provides 2,800 cubic feet of stormwater storage.
• Quality Views: 92% regularly occupied space with quality views of the outside.
• Interior Lighting: 100% spaces with individual lighting controls.
• Thermal Comfort: 98% spaces with individual thermal comfort controls.
• Materials: Transparent, low-emitting, sustainable building materials were prioritized and incorporated.
