While, traditionally, a superior home such as Snap-N-Lock would add 3-5% to the total construction cost when compared to “Stick Built” homes, we anticipate a substantial savings once the 2009 and 2012 IRC building codes are adopted nationwide.   The 2009 code mandates 20% improvement over the 2006 code energy efficiency for 2009 and 30% over 2006 in 2012.   Our homes have shown a “total energy savings” of 35% to 40% savings for the last 15 years over the 2006 code and we are working toward meeting the 2020 code.
