This article covers some important changes to additional efficiency package options, rooms with fuel burning appliances, walk-in coolers and freezers, refrigerated display cases, and equipment buildings.
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.
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.
More regional energy efficiency organizations are examining commercial construction data to gain insights into the commercial construction trends and the economic impact of building energy code adoption and implementation on the construction trends. Raw construction data on permits can help stakeholders understand what kind of impact newer state-level energy code adoption and implementation have on the market and communities at local and state-level.
This op-ed highlights the results of the Southeast Energy Efficiency Alliance’s (SEEA) recent codes research, confirming that the adoption of stronger energy codes across the Southeast has no adverse effect on commercial construction activity. In Georgia, when the state adopted the 2009 IECC with Georgia State Supplements and Amendments in 2011, it saw the largest ever number of activated construction permits.
If every state began 2015 with the 2012 IECC for residential and commercial construction and moved from 60% compliance to 100% compliance by 2030, how much would the cumulative source energy savings, energy cost savings, and carbon emission reductions be in 2030?
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.
