Document type: Model Data
Publication Date: May 2012
Focus: Code Development

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 New York, 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...

Focus: Adoption

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.

At the request of the New York State Energy Research and Development Authority and New York State Department of State, the U.S. Department of Energy's Building Energy Codes Program undertook an analysis of the energy savings and cost impacts associated with the proposed adoption of ASHRAE Standard 90.1-2004, and compared it with the requirements based on ASHRAE Standards 90.1-1999 and 90.1-2001.

Publication Date: April 2004
Focus: Adoption

The state of New York asked the U.S. Department of Energy to evaluate the cost-effectiveness of the requirement for heat recovery for service water heating that exists in the 2003 International Energy Conservation Code to determine whether this requirement should be adopted into the New York State Energy code.

Publication Date: September 2004
Focus: Adoption

The New York State Department of State requested the U.S. Department of Energy (DOE) compare the effects on energy usage as a result of implementation of the 2004 Supplement to the International Energy Conservation Code with the current New York code. The comparison had to determine whether additional costs of compliance with the proposal would be equal to or less than the present value of anticipated energy cost savings over a 10-year period. Under DOE's direction, Pacific Northwest National Laboratory completed the requested assessment of the potential code upgrade.

Focus: Adoption

The state of New York requested that the U.S. Department of Energy's (DOE's) Building Energy Codes Program (BECP) provide an analysis of the impacts of adoption of ASHRAE Standard 90.1-2007. New York State is unique among states in requiring a ten-year payback for energy code measures. BECP based this analysis on the results of a nationwide, state-by-state code comparison for DOE. This analysis indicates that the adoption of ASHRAE Standard 90.1-2007 is cost-effective under New York’s requirements for all buildings in New York.

Publication Date: June 2004
Focus: Adoption

The state of New York asked the U.S. Department of Energy to analyze the potential energy effect and cost-effectiveness of the lighting requirements in the 2003 International Energy Conservation Code as they consider adoption of this energy code. The new provisions of interest in the lighting section of the 2003 IECC include new lighting power densities and requirements for automatic lighting shutoff controls.

In compliance with Title III of the Energy Conservation and Production Act (ECPA) of 1976, as amended, this is to certify that the State of New York has adopted the 2010 edition of the Energy Conservation Construction Code of New York State (the "2010 ECCCNYS") as New York State's building energy code for residential buildings and non-residential (commercial) buildings.

With regard to residential buildings, the 2010 ECCCNYS is based on, and is equivalent to or more stringent than, the 2009 version of the International Energy Conservation Code.

With regard to commercial buildings, the 2010 ECCCNYS is equivalent to or more stringent than ASHRAE 90.1-2007.

A study prepared for the Long Island Power Authority to analyze "new construction practices and market conditions from the summer and fall of 2003." The results of the study were used during the design of the Long Island Power Authority's New York ENERGY STAR Labeled Homes Program (NYESLHP).
