Green Builder Project Frog Leaps Forward with $22M from GE and VCs

Three years ago, modular builder Project Frog made a splash at the international Greenbuild Expo with an eye-catching, energy-neutral classroom that was built on-site in just six days.

Today, the San Francisco-based company is setting its sights on accelerated growth with $22 million in funding from General Electric and some of GE's VC partners in its ecomagination Challenge.

Claremont Creek Ventures, Greener Capital Partners and RockPort Capital Partners joined GE Energy Financial Services in the investment that was announced this morning.

The funding will fuel expansion of Project Frog's sales pipeline, including an increase in the size and types of buildings in its portfolio and the number of projects the company takes on, according to Project Frog CEO Ann Hand.

"This is a step-change year for us," she said of her company's plans and the investment that will enable Project Frog to pursue them.Project Frog at Greenbuild 2008.

I first talked to Project Frog executives in 2008 as the company opened its "Frog Zero" classroom (pictured right) to the thousands who attended the U.S. Buildings Council conference that year in Boston. The structure became part of a three-classroom building that Project Frog created for the Watkinson School in Connecticut.

The school was among the early projects for the firm that specializes in high performance, energy efficient buildings. The buildings are constructed from pre-engineered components in shapes that can be put together in different ways to meet the needs of their owners. Think of a life-sized Erector Set or LEGOs for green building and you have an idea of how Project Frog's building systems work.Inside the Project Frog classroom at Greenbuild.

A Project Frog building is designed to be eligible for a LEED-Silver USGBC green building rating "out of the box," but be cheaper and faster to build -- and less expensive to heat and illuminate -- than a comparably sized, stick-built structure.

Completed building costs for a Project Frog structure can be 10 percent to 25 percent less per square foot than a traditionally built structure, not counting the benefits of reduced operating costs resulting from energy efficiency, said Hand. The company's structures generally use at least 25 percent less energy than those that comply with the strictest buildings codes in the U.S.

Initially focusing on classrooms and structures best-suited for learning, Project Frog is branching out to buildings for healthcare, retail and other commercial businesses. By the end of last year, the 5-year-old firm had completed 15 projects that encompass about 40,000 square feet of space. By the end of this year, the company intends to almost double that amount and bring total built square footage to "somewhere north of 70,000 square feet," Hand said. Project Frog hopes to more than double that amount next year.

The company also is looking to increase the size of its building projects. Typically, they've been single-story structures with an average size of 5,000 square feet. The smallest was 1,200 square feet and the largest so far is 14,000 square feet. Project Frog is shooting for an average building project size of 20,000 square feet next year with no upper limit on maximum square footage. It also expects to work on multiple-story projects, concentrating at first on two-story structures.

Project Frog's building systems, its business model and its track record thus far made it an attractive candidate for funding under GE's ecomagination Challenge, said Ricardo Angel, senior vice president of venture capital at GE Energy Financial Services.
