RIALTO, California – April 20, 2022: Plant Prefab, the first Certified B Corporation™ building technology company dedicated to sustainable design, materials and operations, today released its annual Corporate Sustainability Report. The report summarizes the progress the company made in 2021 advancing its ongoing commitment to social and environmental responsibility.

“2021 was a transformational year for Plant Prefab on a number of fronts,” said Steve Glenn, Founder and Chief Executive Officer of Plant Prefab. “Despite unprecedented market challenges, we managed to advance key business priorities while supporting people, the planet and our stakeholders. These efforts include growing and investing in our workforce – creating more opportunities for employees to advance their professional development – as well as materially expanding our operations with the launch of our second factory and increasing our production by 64% year-over-year, delivering 66,153 square feet of living space. Importantly, we accomplished all of this while reducing our resource consumption and increasing our material efficiency. Achieving this remarkable progress is a testament to the strength of our differentiated business model and our unwavering commitment to prioritize sustainable business practices. We are excited by the opportunities ahead to further advance the construction industry and help address the nation’s housing crisis.”

Plant Prefab’s broad approach to sustainability and corporate responsibility encompasses energy and resource efficiency, waste reduction, water conservation, recycling, material sourcing, supply chain and project management, and employee training. The company’s patented Plant Building System™ is a prime example of how it is building better for the environment and its customers. The system combines advanced engineering with specialized Plant Panels™ and Plant Modules™ to build custom housing 20 to 50% faster than traditional methods with superior quality control and up to 30% less waste. When Plant Prefab’s third factory – an automated, solar-powered production hub (click here for video) – is operational in 2023 the company will be even better positioned to make architectural, sustainable housing more accessible.

This focus on efficient and sustainable practices, along with carbon emission tracking and the purchase of offsets, have enabled Plant Prefab to achieve carbon-neutral operations for the second consecutive year. The company is committed to continue reducing its emissions throughout its value chain, helping to accelerate the transition to a net-zero carbon economy. Highlights from Plant Prefab’s 2021 corporate sustainability report include:


  • 36% reduction in operational carbon emissions per square foot of production year-over-year.

  • 40% reduction in waste per square foot of production year-over-year.

  • 12% reduction in company-wide electricity consumption year-over-year.

  • 76% of construction and demolition waste recycled.

  • Homes designed and built by Plant Prefab performed an average 10.7% better than California Title 24 energy efficiency standards.


  • 92% employee satisfaction rating, reflecting comprehensive training and career opportunities afforded by the company.

  • 20.6% employee turnover rate compared to industry average of 65.5%, demonstrating high employee satisfaction.

  • 20% increase in new jobs created year-over-year.

  • Further diversified and expanded senior management team with the addition of Namrata Vora as Chief Revenue Officer and Jeff Spain as Chief Financial Officer.

  • Recorded just seven cases of coronavirus among employees with only one attributed to workplace transmission, demonstrating the company’s best-in-class illness prevention protocols.


  • 30% of materials by volume have a third-party environmental certification.
