Several municipalities and counties in Northern Nevada recently joined states around the nation by adopting the 2015 IECC Energy Rating Index (ERI) compliance option. The state’s current residential energy code – the 2012 IECC – is still in effect, but has been amended in these locations to include an ERI compliance path and a 2009 IECC thermal envelope backstop.
With the 2018 version of the IECC being developed this year, it seems appropriate to look at the success of the ERI and what the future may hold. The voluntary ERI path for the 2015 IECC gives builders the option of complying with the code by meeting a target Energy Rating Index score. This is a numerical score where 100 equates to the efficiency levels prescribed in the 2006 IECC and 0 is equivalent to a net-zero-energy (NZE) home.
Hawaii, Maryland, New Jersey, Texas, and Vermont all adopted new energy codes in 2015.
The Department of Energy has announced findings on energy savings from adopting and complying with the 2015 International Energy Conservation Code (IECC). Compared with residential buildings meeting the 2012 IECC, the 2015 edition achieves national source energy savings of approximately 0.87 percent, site energy savings of approximately 0.98 percent, and energy cost savings of 0.73 percent of residential building energy consumption.
Air pollution is a top concern for Utah citizens. So is financial stability. Improving our air quality while saving money for Utahns is a win-win opportunity. This summer, decision-makers will be voting whether or not to adopt up-to-date building energy codes that will help new homes and buildings constructed in Utah cut energy waste, lower air pollution and reduce Utahns’ energy bills.
There was a lot of buzz around the residential provisions in the 2015 IECC last year but not enough around the commercial provisions. Major changes in commercial buildings for the 2015 IECC include increased commissioning and upgrades for HVAC, water heating, and lighting.
Energy efficiency rang in the New Year with seven states implementing new and improved building energy codes. The 2015 IECC, the latest version of the energy code, is now enforced in Maryland and Vermont; the 2012 IECC is implemented in Idaho, Minnesota, and New York; and the 2009 IECC is used in Arkansas and Louisiana. Here are some key facts about the new state code updates.
Looking at what makes the 2015 IECC different from the 2012 version, the biggest change that will affect builders is the addition of an Energy Rating Index (ERI) compliance path. This article will outline some other important changes. Five of the major changes in the 2015 IECC that will affect new home construction include specifying required inspections; revised requirements for vertical access doors; a new requirement for combustion closets; revisions to the building envelope air leakage testing requirements; and revised requirements for duct insulation.
BCAP asked the National Energy Codes Collaborative: What have we done in 2014?
Last November, ICC rolled out is much-anticipated solution – a remote voting system called “cdpACCESS.” The new cloud-based online tool has the game-changing potential to broaden participation by GMVRs to literally tens of thousands, a far cry from the hundreds who have cast final action votes on ICC’s 15 I-Codes.
The Pacific Northwest National Laboratory analyzed the relationship between the Residential Energy Services Network (RESNET) Home Energy Rating System (HERS) Index and the traditional simulation-based Performance Path used in the International Energy Conservation Code (IECC). These findings will be important to be aware of as states and municipalities begin to consider adoption of the 2015 IECC, which includes a HERS-like rating system as an alternative compliance path.
Sound energy policy prevailed as local and state governmental officials rejected dozens of builder-sponsored home efficiency rollback proposals in a three-day marathon meeting convened by the International Code Council (ICC) to develop the 2015 International Energy Conservation Code (IECC).
With hard-fought efficiency gains at stake, the U.S. Conference of Mayors voted unanimously to encourage municipal support for all eligible code officials to attend the ICC’s Final Action Hearings this October in Atlantic City to support continued efficiency gains for America’s model energy code, the International Energy Conservation Code (IECC). The local and state code and other officials voting at the hearings will consider amendments to the 2012 IECC)that will become the 2015 IECC. The IECC is recognized in federal law as America’s model energy code and is adopted in some form by nearly every state.
