ENERGY STAR Evolves

When the 2012 International Energy Code goes into effect next year, it will be an approximate 28% improvement over the 2006 code. That jump in efficiency is unprecedented. While the late 80’s saw gains of around 10%, things hit a plateau from 1991 through 2008, a span of 17 years that saw a total of only 6% improvement in building energy efficiency, despite the fact that codes are updated every three years.

The pace picked up with the introduction of the 2009 International Energy Conservation Code (IECC). The new code, driven in part by energy reduction goals set by the Department of Energy, raised the efficiency of new buildings by about 13% compared to the 2006 version. The 2012 code aims at another 15%.

What's Changed

The 2009 code improved efficiency in part by adding specificity to what had been stated in general terms. For instance, it required that half of new lighting fixtures be hard-wired high-efficiency fixtures (LEDs or CFLs), and added specific requirement for sealing HVAC ducts as well the building envelope.

The 2012 code will raise insulation levels, set even stricter sealing requirements, raise the high-efficiency fixture requirement to 75% and disallow the use of building plenums to move air from the HVAC system, among many other new requirements.

NEW CODE REQUIREMENTS FOR 2012

When the 2012 IECC goes into effect, builders in jurisdictions that adopt it will face the following changes.

Energy Codes are driving the building industry to new heights of energy efficiency. However new requirements present new challenges for the builder. Energy Smart works closely with homebuilders addressing these type challenges and providing cost effective solutions.
