The Douglass on Track to Become the Largest Zero-Carbon Multifamily in the Country

Phase I of Redbrick LMD's Bridge District, The Douglass, is on track to become the largest ILFI zero-carbon multifamily residential building in the country. The Douglass, designed by ZGF Architects, exemplifies how responsible development can foster community connections, support healthy living, and mitigate the impacts of climate change. 

With a focus on reducing both operational and embodied carbon, the Douglass is on track to become the largest ILFI zero-carbon multifamily residential building in the country and the first in the DC region. The Douglass will be all-electric and powered by renewable energy generated via a rooftop solar array and off-site sources, an achievement that aligns with the District’s goal of electrifying all new homes and commercial buildings by 2032. Solar analyses influenced the building’s orientation, massing, and glazing, resulting in an anticipated 25% energy reduction over baseline. The design team worked with Redbrick and HITT Contracting to reduce the carbon emissions associated with the building’s structure, envelope, and interiors. The team used ZGF’s open-source Concrete LCA tool to calculate and compare the carbon impacts of proposed concrete mixes for the building’ structure, while EC3 helped the team measure the whole building emissions. The Douglass is tracking a 15% reduction in embodied carbon. Furthermore, the building will encourage sustainable transportation, by providing bicycle parking, a bike repair station, a bike wash, 20% electric vehicle charging stations, and proximity to public transportation.
