Over the next several weeks we are going to break down the Green Building Program in DC to help you better understand what it means to your next building project. But first let’s start with the basics of what it really is. In 2012 the District was the first jurisdiction in the nation to adopt both the 2012 International Energy Conservation Code and the 2012 International Green Construction Code and more recently the 2013 Green Construction Code. Mayor Vincent Gray has a vision to be a national leader in sustainable building practices and making the city a cleaner place for visitors and residence to live, work and play.  Below is the Mayor’s direct quote on his vision and the direction of the District as it pertains to sustainable green living.

Mayor Gray’s Vision

''In just one generation - 20 years - the District of Columbia will be the healthiest, greenest, and most livable city in the United States. An international destination for people and investment, the District will be a model of innovative policies and practices that improve quality of life and economic opportunity. We will demonstrate how enhancing our natural and built environments, investing in a diverse clean economy, and reducing disparities among residents can create an educated, equitable and prosperous society.''

As part of this initiative the Department of Consumer and Regulatory Affairs (DCRA) has created a separate division known as Green Building. This new division operates under DCRA and is responsible for permitting & inspections. They oversee and work with sister agencies to make sure that the rules, regulations and codes are being followed properly. This agency also supports and helps implement the Sustainable DC Plan. Within the green building program DCRA has developed an online resource to help you better navigate if your project falls under any of these regulations.  The roadmap covers the Green Building Act, Green Construction code, Energy Construction Code, Green Area Ratio, and the Stormwater Regulations. You can visit the road map at www.dcra.dc.gov for more details.
