The History of IgCC

When it was developed, Optima Sonoran Village had the privilege of being the pilot project for Scottsdale’s International Green Construction Code, an alternative to LEED fully managed by local municipalities, and was one of the first projects in the world certified under IgCC. To understand the true breadth of its merit, we’re taking a deep dive into the code: its history, its mission and its modern day impact. 

History of IgCC

IgCC was first conceptualized by the International Code Council (ICC), a nonprofit association that provides a wide range of building safety solutions including product evaluation, accreditation, certification, codification and training. ICC also develops model codes and standards that are used around the world to construct safe, sustainable, affordable and resilient structures. 

ICC realized that there was a significant gap in construction in the way of a mandatory baseline of codes that would address green commercial construction. This kind of regulatory framework was becoming an increasingly appealing concept, with many local and state jurisdictions already exploring their own potential “substitute codes.” 

In response to the call, ICC collaborated with cooperating sponsors – the American Institute of Architects (AIA), ASTM International, ASHRAE, the U.S. Green Building Council (USBGC) and the Illuminating Engineering Society (IES) to help get the code passed. And in 2010, ICC established The International Green Construction Code(IgCC) to provide model code regulations that promote safe and sustainable construction. 

IgCC Today

IgCC “provides the design and construction industry with the single, most effective way to deliver sustainable, resilient, high-performance buildings.” Support of the IgCC promotes a new era of building design and construction that includes environmental health and safety as code minimums.

Benefits of certification under IgCC abound; IgCC certification includes measures that result in better indoor environments, lower impact on natural resources, better neighborhood connections and improved walkability, increased resilience to natural disasters and climate change, resource consumption/management and service interruptions.

IgCC and Optima

IgCC operates as a code that can be easily adapted by public or private entities, allowing government jurisdictions to adopt it and save themselves the labor of creating their own code. Arizona took advantage of this opportunity, adopting the IgCC, which then took effect in January of 2017. 

It was at that time that Optima Sonoran Village became a pilot project for IgCC in Arizona.

Optima Sonoran Village IGCC attributes include major building elements consisting of 95 perfect local and recycled content materials; energy efficiency as a result of the high-performing glazing, overhangs, building configurations and exterior shading devices; water resource conservation from plumbing fixtures and excellent indoor environmental quality and reduced material emissions from the materials used in the development. Because of its environmentally-friendly construction, Optima Sonoran Village passed muster and was one of the first buildings in the world to earn certification.

Optima will continue to push the boundaries of building in pursuit of new and sustainable ways to contribute to our built environment. ICC is an association that will continue to do the same—we look forward to a world in which green building is commonplace.
