As development in South Florida begins to flourish once again, so are the many different types of Green Rating Systems available to the builders and developers of these thriving projects. Although LEED (Leadership in Energy and Environmental Design) still remains at the forefront, there are other Green Rating Systems that are making a presence in the market place; ones in particular that The Spinnaker Group now offers consulting for is the National Green Building Standard and the Living Building Challenge. Here we will focus on the National Green Building Standard. So what makes this system different from LEED? What sets it apart from the others? We’ve decided to answer these questions in an attempt to educate our clients and the A+D Industry, after all the “early bird gets the worm”.
National Green Building Standard
NGBS is the first and only residential and multi-family green building rating system approved by the American National Standards Institute (ANSI). It is not meant to be used on your typical new construction commercial building project. The NGBS provides practices for the design and construction of all types of green residential buildings, renovations, and land developments. The green aspects of the NGBS include lot design, preparation and development; resource, energy and water efficiency; indoor environmental quality; and operation, maintenance and building owner education. It also provides flexibility allowing the developers to make green choices based on climate and geography as well as style preferences and budget. Unlike how LEED Buildings are certified by a Professional Commissioning Agent, NGBS buildings are verified through an expansive third-party rating system to achieve green certification. In 2012 the standard was updated for the first time since being released in 2009.
“The 2012 edition incorporates several changes that not only make the standard much easier to use, but also expand the offerings for renovations and remodeling projects, and raise the bar on energy efficiency,” said NAHB Chairman Rick Judson. ” We have seen phenomenal growth in green building in recent years, and the new version of the standard will only help to add to this.”
Some of the more notable updates include:
• The Energy Efficiency chapter has been substantially revised with the new more stringent rating levels based on whole-house energy savings above the 2009 International Energy Efficiency Code.
• The remodeling provisions have been incorporated into two new standalone chapters and include options for rating an entire remodeled building or achieving minimum compliance for a remodeled functional area such as a kitchen, bathroom, basement or addition.
• The point assignments for water efficiency practices have been reanalyzed to achieve an improved internal consistency with regard to actual water savings.
• The durability provisions have been reorganized, expanded and compiled into a single section as part of the Resource Efficiency chapter.
As with LEED, the NGBS has a point based system for achieving different levels of green buildings.
