Northern Nevada Welcomes a New Compliance Path

nevada-2015-iecc-01

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.

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.

Highlights of the 2015 IECC Residential Code Changes

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.

HERS and the IECC Performance Path

2012-iecc

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.

While many states have worked hard to adopt the 2009 or 2012 IECC, implementation and compliance are sometimes overlooked. But that is changing. National, regional, and local focus is shifting to address meeting the 90 percent compliance goal set by the American Recovery and Reinvestment Act of 2009. Working with numerous state energy offices to investigate and assess a state’s existing energy code infrastructure, one common weakness BCAP identified was a lack of awareness, understanding, and involvement in the building energy code development process by design professionals.

Alliance To Save Energy Hails 25-30% Advance In 2012 Energy Code For New and Renovated Residential, Commercial Buildings

2012-iecc

Washington, D.C., July 28, 2011 – The Alliance to Save Energy today hailed a newly-released model building energy code upgrade that will improve energy use in commercial and residential buildings in the United States by as much as 30%. The landmark 30% improvement for new and renovated residential buildings is included in the 2012 International Energy Conservation Code (IECC), which also would increase the energy efficiency of commercial buildings by about 25% when compared to the 2006 version of the code.
