Sustainable Spaces Secures $6 Million Series A

Date: 09/23/2008

Company: Sustainable Spaces

SAN FRANCISCO, CA – September 23, 2008 – Sustainable Spaces, a national leader in the growing field of home energy efficiency and health, today announced it has closed its Series A funding. The company secured $6 million dollars from RockPort Capital Partners and Shasta Ventures. The infusion of funding will enable the company to invest in building its infrastructure to meet the exploding demand for its services.

Sustainable Spaces brings homes up to today’s high standards of energy efficiency, health and comfort by applying building science to conduct home energy audits and retrofit projects. Existing homes currently account for almost 21% of the U.S. carbon output, more than all the cars, trucks, and buses combined. Energy efficiency is one of the most cost-effective avenues for improving energy security, reducing energy bills, and addressing the important issue of global climate change—all while creating green collar jobs and growing the economy. Since 2004, the company has performed over 400 home retrofits in the San Francisco Bay Area, lowering homeowners’ energy usage and expense by an average of 40%, while improving indoor air quality and thermal comfort.

“We are very pleased to be working with investors who understand the value proposition and market potential of our business and are committed to successfully growing companies that can make a real impact on global climate change and the emerging green economy,” said Pratap Mukherjee, CEO of Sustainable Spaces. “There are more than 70 million single-family, owner-occupied homes in the U.S. and they typically use one and a half to two times the energy required to achieve the homeowners’ desired level of comfort. Finding the causes of wasted energy in homes and fixing the underlying problems represent the single most potent and cost-effective measure we can take to combat global warming.”

“Sustainable Spaces has created a compelling value proposition for homeowners,” said Chuck McDermott of RockPort Capital Partners. “By addressing each individual homeowner’s concerns and constructing an improvement roadmap customized to that customer, they can work within any homeowner’s budget to reduce their bills and make an impact on global climate change. Our investment enables the company to further increase the tremendous results they have seen in their local market and expand their programs into new markets.”

“There’s a massive opportunity to create the trusted brand in home performance to help homeowners sort through the dizzying array of green products and services in the most cost-effective way possible,” said Tod Francis of Shasta Ventures. “Sustainable Spaces has been leading the way with a track record of providing a very high quality service enabled by leading building science know-how. We are very excited to be working with the company on the ground floor of this growing sector.”

Founded in 2004, Sustainable Spaces has been a national leader in creating the home performance industry. The company is committed to its employees, and has created more than 40 positions in living wage jobs with a full benefits package. The company is also closely involved in local green collar jobs programs, and is committed to giving back to the communities in which it does business.
