Since 1994, IBACOS has been a strategic partner to the U.S. Department of Energy (DOE)
in the effort to improve residential building performance. IBACOS continues to work at the
cutting edge of advancing new technology and high-performance best practices in the industry
and is currently engaged with The Advanced Clean Communities Collaborative (AC3).
This project is part of Connected Communities – a series of projects that work to demonstrate
how groups of buildings can reliably and cost-effectively serve as assets to the grid.
Efficient, connected, smart and flexible buildings are key to modernizing U.S. infrastructure, lowering energy use and improving the nation’s electricity grid.

Led by IBACOS, the AC3 project involves collaboration from several partners including
Duke Energy, Meritage Homes, Mattamy Homes, American Homes 4 Rent, Elevation, EnergyHub, Tierra Resource Consultants, Energy & Environmental Economics (E3), and
the National Renewable Energy Laboratory (NREL).
Over the course of the 4-year project, up to 1,000 new and existing single-family and multi-family homes in Duke Energy’s North Carolina service territory will be connected to serve utility peak capacity and resource adequacy needs at the bulk system and local transmission and distribution level.


Data on aggregated grid impacts and value across a range of homes, end uses, and technologies will be collected to help identify best approaches to delivering flexible distributed capacity at scale.
New business models between utilities,
homebuilders, existing home providers, and
customers will be essential to the success of these programs and will provide new value streams to each of these stakeholders.
