Exhibitors, manufacturers, and policymakers gathered on the National Mall for the fourth iteration of the Innovative Housing Showcase (IHS).

The public event aims to raise awareness of innovative and affordable housing designs and technologies that have the potential to increase housing supply, lower construction costs, increase energy efficiency and resilience, and reduce housing expenses for owners and renters.

At the 2024 IHS, dozens of exhibitors canvassed the nation’s capital, displaying technologies, innovations, and solutions geared toward addressing affordability, increasing housing inventory, and enhancing the sustainability, resiliency, and efficiency of the built environment. The exhibitors ranged from product manufacturers, such as James Hardie, Daytek, and Solaris Toilet, to companies displaying full-sized prototype homes built using a variety of innovative building technologies.

The exhibitors included:

The SBCA once again installed a fully framed, two-story, 2,400-square-foot house on the National Mall in less than eight hours. 84 Lumber provided the structural framing elements, windows, doors, and framing crews for the 2024 installation. According to signage inside the house, component framing can deliver savings of more than $20,000 compared with traditional stick framing and labor advantages. The SBCA also highlighted that manufactured components are designed to exceed load requirements for improved durability and can be designed with energy efficiency in mind.

When divided by the fire wall, it creates two Energy Star-certified, one-bedroom dwellings. At 70 feet long and 15.5 feet wide, the floor plan is suitable for both narrow lots or developers wanting to maximize depth and curb appeal, according to Cavco. The Blue Ridge model is part of the Anthem duplex series, which Cavco says is “the most practical, logical, and affordable solution” for increasing density and developers looking to diversify their real estate portfolio.

Green Canopy NODE highlighted the advantages of mass timber off-site construction on its unit assembled at the National Mall. The company’s prefabricated utility kits reduce the traditional mechanical, electrical plumbing install time by 50%, eliminating a source of inefficiencies and call bucks. The mass timber turnkey structural solution is also a “carbon sink” and designed for deconstruction and the circular economy, according to Green Canopy NODE. Since the utility kits are preconstructed in an off-site factory during site work, the kits are ready for a smooth and seamless installation process during the framing phase. The Prefabricated Mass Timber Building Kits are available for cottages, ADUs, townhomes, and apartments.
