The U.S. Green Building Council (USGBC) now estimates that there are as many as 150,000 LEED-certified green housing units worldwide, a number that more than doubled between 2011 and 2012 and continues to grow steadily, according to the organization's LEED in Motion: Residential report released today.
The report is the latest in USGBC's popular LEED in Motion series designed to equip readers with the insight and knowledge to understand LEED, the world's most widely used and recognized green building rating system, and to make the case for sustainable building practices worldwide. The report also details the U.S. states with the most LEED-certified homes, with California in the No. 1 spot followed by New York and Texas.
With the official start of summer just days away and Americans bracing for higher energy bills, the benefits of LEED-certified houses are even more pronounced. LEED-certified homes provide 20 to 30 percent savings in energy and water use compared to code-built homes, and they maximize fresh air indoors while minimizing exposure to airborne toxins and pollutants.
"Our homes are more than just spaces that provide shelter," said Rick Fedrizzi, president, CEO and founding chair, USGBC. "Homes touch practically every aspect of our lives and are a critical element of our overall sense of safety, identity and community. Enhancing our homes' efficiency and resilience offers an extraordinary opportunity to further the revolution in sustainable building and living practices so that it ripples outward to our communities. As demonstrated in LEED in Motion: Residential, this movement is already well under way."
Featuring a foreword from Nest CEO and founder Tony Fadell, the report explores the multiple LEED rating systems for different types of homes, including new single-family homes as well as new and existing low-rise, mid-rise and high-rise multifamily buildings. USGBC is also developing a rating system for existing single-family homes.
