This report described the results of a two-year Northwest Energy Efficiency Alliance study intended to improve understanding of the new commercial building stock in the Pacific Northwest region. It provided a new regional baseline for practices in commercial buildings constructed between 2002 and 2004 and compared those practices with previous baseline and code compliance studies conducted from 1996 to 1998. The study also looked at changes in design professionals' attitudes toward energy efficiency across the same periods.
The following codes are hereby adopted for the state of Idaho Division of Building Safety and shall only be applied by local governments as prescribed by section 39-4116, Idaho Code:(a) The 2006 International Building Code shall be in effect, until such time as a subsequent version is adopted by the Idaho building code board, at which time the subsequent versions of the International Building Code as adopted and amended by the Idaho building code board through the negotiated rulemaking process as established in section 67-5221, Idaho Code, and as further provided in subsection (5) of this section and in accordance with subsections (2) and (3) herein shall be in effect.
This document serves as an example for cities or counties within Idaho to use when creating model building code ordinances.
The International Energy Conservation Code (IECC) prototype building models (prototype models) were developed by Pacific Northwest National Laboratory (PNNL), in support of DOE's Building Energy Codes Program (BECP), to simulate energy savings associated with changes in energy codes and standards. For residential buildings, PNNL utilized two base prototypes to simulate both Single-family detached house, and Multi-family low-rise apartment building types. Energy models for the 2006, 2009 and 2012 versions of the IECC are available for each state.
This set of IECC Prototype Building Models is for the state of Idaho, using the 2006 IECC as the baseline code.
Each ZIP file includes EnergyPlus model input files (.idf) and corresponding output files (.html).
This nationwide analysis of commercial energy code compares ASHRAE Standard 90.1-2007 with the commercial code in each state as of June 2009. The results are provided in chapters specific to each state.
States with unique energy codes were not included in the analysis because the codes in these states would be difficult to appropriately compare to ASHRAE Standard 90.1 and most of these states have energy offices that routinely assess their codes against the model codes. In states with codes prior to and including the 2000 IECC or Standard 90.1-1999, those states with no statewide energy code, and home rule states which did not specifically request that another code be used, Standard 90.1-1999 was used as the baseline for comparison.
Three DOE Benchmark buildings were used for the simulation used in this analysis: a medium office building (53,600 ft2), a mid-rise apartment building (33,700 ft2), and a non-refrigerated warehouse (49,500 ft2...
This analysis of residential energy code compares the requirements of the 2009 International Energy Conservation Code (IECC) with the residential code—or typical construction practice in the absence of a code—in most states as of June 2009. The results, which include estimated typical energy savings of updating each state’s code to the 2009 IECC, are provided in chapters specific to each state.
Several states have either not adopted a mandatory energy code or developed their own codes which have minimal or no connection to the IECC. The latter—including California, Florida, Oregon, and Washington— were not included in this analysis because the codes in these states would be difficult to appropriately compare to the 2009 IECC and most of these states have energy offices that have already assessed the IECC on their own.
A study prepared for the Northwest Energy Efficiency Alliance that "characterize ssingle-family residential new construction using a representative sample of buildings constructed in 2004 and 2005...The results will provide a baseline for ENERGY STAR® New Homes Northwest specifications."
Pacific Northwest National Laboratory (PNNL) conducted a series of cost effectiveness analyses for the U.S. Department of Energy (DOE), covering the 2009 and 2012 editions of the International Energy Conservation Code (IECC) for new single and multifamily homes. The evaluations were performed against a 2006 IECC baseline, taking state-specific code amendments into consideration. These reports outline the results of these analyses, including a National Cost Analysis and Cost Analyses for selected states.
