The U.S. Department of Energy's Advanced Building Construction (ABC) Initiative is channeling hundreds of millions of dollars into reshaping how American buildings are designed, constructed, and retrofitted - with modular standardization and workforce training at the center of its strategy.
Background
The ABC Initiative, led by DOE's Building Technologies Office (BTO), integrates energy-efficiency solutions into high-productivity U.S. construction practices for new buildings and retrofits. The program's urgency stems from a structural problem: while industries such as manufacturing and communications have transformed through digitization and process improvements, U.S. construction productivity has consistently declined since 1968. A 2017 McKinsey Global Institute report identified underinvestment in innovation, industry fragmentation, and insufficient skilled labor as key contributing factors.
The scale of the challenge is significant. The U.S. building stock accounts for 75% of total U.S. electricity use and 40% of energy use. To meet national climate goals, the country must decarbonize its building stock by 2050 - a target requiring an approximately 15-fold increase in the residential retrofit rate from current levels.
Initiative Scope and Funding
ABC combines advanced methods - including offsite construction, design for manufacturing and assembly, packaged mechanical systems, robotics, and 3D printing - with low-carbon materials and high-efficiency building systems. The initiative develops technologies deployable quickly with minimal onsite construction time and coordinates key stakeholders to address related challenges such as workforce training, business models, demand growth, and service delivery.
DOE has deployed successive rounds of competitive funding to advance these goals. BTO awarded $26.3 million to 40 competitively selected projects led by 29 organizations to pursue innovations underpinning the ABC Initiative. A subsequent round saw DOE award $31.8 million to seven project teams to demonstrate how advanced construction techniques integrated with energy-efficient technologies can seed the next generation of building retrofit solutions. DOE later announced $33.5 million for energy-efficient, advanced building construction technologies and practices, targeting deep energy retrofit and new construction technologies.
The Rocky Mountain Institute received funding to establish a national collaborative of building and construction stakeholders. Its mandate: accelerate the development, demonstration, and standardization of innovative high-performance construction technologies, with a focus on modular, offsite, and prefabricated approaches.
Workforce Development Pipeline
Workforce reform is a core component of the ABC agenda. Recipient project teams - composed of technology firms, manufacturers, nonprofits, academia, public housing authorities, designers, engineers, and architects - are directed not only to demonstrate new technologies but to work, train, and learn together to develop common, durable practices for a robust building retrofit workforce.
Multiple institutions have received dedicated workforce funding under the initiative:
- Lane Community College and the University of Oregon partnered to establish a workforce development pipeline to increase throughput of highly qualified graduates with hands-on experience in building energy efficiency.
- The Interstate Renewable Energy Council received funding to develop an interactive career map demonstrating career pathways and conduct strategic outreach to foster a talent pipeline for the building energy-efficiency industry.
- Lane Community College separately received funding to create a Building Energy and Controls Apprenticeship Program, preparing graduates to identify and implement energy-saving measures in medium to large commercial facilities.
The initiative aims to ensure that underserved communities actively participate in a reimagined construction workforce and gain access to low-carbon, high-quality building solutions.
Digitization and the ABC Collaborative
Through advanced building construction techniques - offsite manufacturing, robotics, and digitization of design and construction processes - new projects can be completed more quickly and affordably while achieving dramatically better energy performance. The initiative explicitly funds research into software and digitization as prerequisites for scaling modular and prefabricated approaches.
The ABC Collaborative brings together a broad array of building industry stakeholders - including building owners and developers, manufacturers, suppliers, installers, R&D organizations, workforce training bodies, financiers, insurers, code officials, and government agencies - to accelerate the standardization and mainstream adoption of high-performance construction technologies, creating a pathway to market transformation.
National laboratory research is also advancing digital tools for prefabricated installation. Oak Ridge National Laboratory won a 2024 R&D 100 Award for its Real-Time Evaluator for Fast and Accurate Installation of Prefabricated Components.
Outlook
DOE-selected project teams are tasked with demonstrating next-generation whole-building retrofit approaches that reduce thermal energy loads by at least 50-75%, with demonstrations planned across a wide range of climates, geographies, building types, and workforce models. Together, the funded teams will bring ABC innovations to more than 30 existing buildings nationwide, with the majority located in low-income communities. The scale and geographic breadth of these pilots will shape future procurement guidance and building standards as DOE works toward a carbon-neutral U.S. building stock by 2050.
