Green Building Regulations

While much of the emphasis on green building centers around talk of LEED certification, the best known and most widely accepted certification system, 2009 has introduced several new regulations and codes which are worthy of discussion.
The first of these is the ASHRAE Standard 189. Some of you might remember that ASHRAE attempted to develop their green building standard last year but abandoned their attempt after complaints from several industry groups that their interests were not properly represented. Section 189 is titled "Standard for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings". On January 27, 2009 the committee was expanded to include 34 voting members and seeks to implement a code which will outline minimum criteria for green building practices, the standard will be applicable to new commercial buildings and major renovation projects. When completed, it will address energy efficiency, a building’s impact on the atmosphere, sustainable sites, water use efficiency, materials and resources, and indoor environmental quality, among other high-performance green building issues.
On January 29, 2009 ICC- 700 was approved as the American National Standard. The new Standard provides guidance for safe and sustainable building practices for residential construction, including both new and renovated single-family to high-rise residential buildings. This is the first and only green standard that is consistent and coordinated with the Code Council’s family of I-Codes and standards. Board President Adolf Zubia said, “this is an enormous step forward in bringing focus to green practices for the built environment. ICC-700 provides a benchmark for green building in the residential market, serving as a new and needed starting point for comprehensive approaches to green residential construction. This is the result of many months of hard work by our members and our partners around the country.”

The standard’s rating system allows builders, designers and communities to choose the levels of high-performance green buildings that best suit their needs. Key provisions include:
• Land conservation
• Rainwater collection
• Construction of smaller homes to conserve resources
• Energy performance starting at 15% above the baseline requirements of the 2006 International Energy Conservation Code
• The use of low VOC (Volatile Organic Compound) materials and detached garages or carports to improve indoor environmental quality
• Homeowner education on proper maintenance and operation to maintain its green status throughout its life cycle

ICC-700 is available at the following website.

Stay tuned for more news regarding these codes and how they will be implemented in green construction projects around the country. It is important to note the increased flexibility that ICC-700 offers over LEED to those construction residential houses.
