Denver-based RavenBrick has secured a $5 million round of equity funding. The investment, from an affiliate of Aravaipa Venture Fund of Boulder, enables RavenBrick to build its automated production line and begin large-scale fabrication of the company's patented RavenWindow solution.

"In any structure, windows are the weakest link and the largest consumer of energy," said RavenBrick CEO Alex Burney. "Commercial and residential demand for the next generation of energy-efficient window technology is expected to be $1.7 billion by 2017, and RavenBrick's new Denver production facility will be ready to meet that demand."

RavenWindow is the only cost-effective dynamic window solution that reduces energy use by more than 30 percent, by capturing and using heat in cold temperatures and reflecting heat when temperatures rise.

"Unlocking the potential of building energy efficiency is one of our top initiatives," said Paul Scharfenberger, Finance Manager of the Colorado Energy Office (CEO). "We selected RavenBrick to receive a loan from our Revolving Loan Fund because its technology is driving significant advancements in the next generation of efficient building products and the company is poised to create a significant number of jobs in Colorado."

"Denver has more than 300 days of sunshine each year, making it a perfect home and testing ground for RavenBrick's smart solutions," said Mayor Michael B. Hancock, whose Office of Economic Development provided early financial support to RavenBrick. "Innovative companies like RavenBrick that start in Denver and stay in Denver demonstrate our national reputation as a pro-small business, high-tech hub."

RavenBrick's automated facility will produce 1 million square feet per year of dynamic energy-efficient RavenWindow technology for use in commercial and residential windows.
