The International Energy Conservation Code

The International Energy Conservation Code (IECC) was created by the International Code Council in 2000. The Council establishes parameters that are often adopted by local and municipal building authorities to ensure that buildings are safe, fire resistant and energy efficient. The IECC is reviewed and revised periodically, then adopted by the building community over the ensuing few years.

The two editions of the IECC that are currently setting the standards for energy efficient building standards are IECC 2009 and the new IECC 2012. Changes in the codes reflect the latest understanding of home safety and efficiency, and are interesting in contrast with traditionally accepted tenets of building. For example, one long-standing belief that has been completely re-evaluated is that homes should be built to “breathe” allowing a passive exchange of air through the structure. The new IECC standard is that homes should be built “tight” with proper mechanical systems to allow for an appropriate exchange of air. The unit of measurement that addresses this “tightness” is the ACH (Air Changes per Hour). The new standards in building have improved energy efficiency so dramatically over the past that it is almost impossible to retrofit an older home to meet the new ACH standards without spray foam insulation.

Another change that is introduced in the IECC 2012 is that the only acceptable method of evaluating a home’s efficiency via an Energy Audit is with a Blower Door. In the past, contractors could choose to follow a checklist to evaluate a home, but the technologically superior Blower Door audit has become the industry standard. Atlantic Spray’s recent certification to conduct Blower Door testing not only puts us in compliance with IECC 2012, but keeps our company at the leading edge of energy efficiency technology

Spray foam insulation is rapidly becoming the standard in both new home construction and older home renovation. If you are interested in its application at your home, contact our Atlantic Spray Systems, Inc. experts and ask for your free estimate today!
