It's time to reimagine how we build, with productivity, climate consciousness, and affordable housing top of mind.
All the while, we’re experiencing a global affordable housing crisis and a climate crisis.
And yet, productivity in the building construction industry has remained stagnant.
Most manufacturing industries have evolved over time, increasing in productivity and accountability to people and planet.

Construction Systems
Scroll to learn more
An Optimized Modular Construction (OMC) System is a building model that seamlessly integrates the design of a construction facility with that of the high-performance, all-electric multifamily units created within its factory walls.
WHAT IT DOES
An OMC System focuses on the human element – on the welfare of both workers and future building occupants alike. Factories employing OMC System methodologies generate increased productivity while containing cost and maximizing energy performance.
HOW IT WORKS
Energy efficiency and renewable energy elements are incorporated from the earliest phases of building design, and monitoring is thoughtfully integrated, measuring factory performance and building energy performance alike.

Modular construction. Optimized.

  • Construction in the factory can continue uninterrupted through all seasons and weather. Building in tandem with site preparation and foundation work is also possible, maximizing productivity further still. On well-coordinated projects, construction timelines can be reduced by up to 50%.
  • Integration of energy efficiency measures at the earliest stages of the building process makes for a proven and predictable order of operations resulting in marked positive results. Unit performance goes up. Energy costs go down.
  • OMC Systems leverage factory construction’s standardized approach to building and quality control. Deliberate, methodical processes facilitate the seamless integration of energy efficiency measures and the creation of a better product overall.
  • Time-savings and improved quality both help to contain costs relative to a code-minimum building. Factory construction also minimizes waste and discourages change orders.
  • The Inflation Reduction Act (IRA) leads the way with billions earmarked for clean energy. Credits are available for commercial building improvements as well as for new home construction meeting ENERGY STAR® home program or DOE Zero Energy Ready Home program requirements.
  • Streamlined, optimized jobs are transforming the workplace. The addition of on-site resources such as classrooms, conference rooms, cafeterias, and daycare adds considerable value for employers and employees alike, positively impacting productivity, retention, and quality of life.

CHALLENGE
Though an improvement compared to working on-site, most factories are cold in the winter and hot in the summer. In fact, many facilities often lack ventilation beyond an open bay door.

Attracting and maintaining the workforce of the future demands better.
SOLUTION
An OMC System addresses such concerns while adding valuable efficiency benefits and economizing operating costs.
Modeling shows that all-electric, high-performance factories with ventilation are cost-effective to own and operate relative to factories of standard construction.
