This report was developed by Pennsylvania Housing Research Center (PHRC) in order to describe PHRC’s energy code technical assistance pilot program and to report the conclusions of the energy code enforcement and compliance study. The program focused on providing a technical assistance program and assessing “common energy enforcement and building practices” for several municipalities, COGs and third- party agencies that volunteered for the program.

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 Pennsylvania, 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.
The Pennsylvania Housing Research Center (PHRC) has created a proposed alternative path for complying with the energy efficiency provisions of the2000 International Energy Conservation Code (IECC) or the 2000 International Residential Code (IRC) for residential buildings. The Pennsylvania Department of Labor and Industry requested that the U.S. Department of Energy (DOE) evaluate the PHRC proposal to determine whether it meets or exceeds the energy efficiency requirements of the IECC. Under DOE's direction, Pacific Northwest National Laboratory reviewed and assessed the PRHC proposal.
In November 1999, the Pennsylvania Legislature passed ACT 45, known as the Uniform Construction Code, into law mandating a statewide building code across Pennsylvania. Act 45 requires the Pennsylvania Department of Labor and Industry (DLI) to promulgate regulations to implement the requirements of the legislation and, in addition, to consider the development of alternative prescriptive methods for energy conservation that account for the various climatic regions within the Commonwealth. In deriving these energy standards, the DLI was to seek to balance energy savings with initial construction costs.
In accordance with the provisions of Section 304(a) of the Energy Conservation and Production Act (ECPA), as amended, this is to certify that the Commonwealth of Pennslyvania has adopted the 2009 International Energy Conservation Code (IECC) and, by reference, ASHRAE 90.1-2007.
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.
These analyses evaluate the cost-effectiveness of the prescriptive path of the 2015 edition of the International Energy Conservation Code (IECC), relative to the 2006 IECC for all 50 states and the District of Columbia. The analysis covers one- and two-family dwelling units, town-homes, and low-rise multifamily residential buildings covered by the residential provisions of the 2015 IECC. These reports were originally published in October 2015, and updated in February 2016 to update numbers reported in certain results tables.
