The purpose of this analysis is to examine the cost-effectiveness of the 2010 edition of ANSI/ASHRAE/IES1 Standard 90.1. Standard 90.1 is the model energy standard for commercial and multi-family residential buildings over three floors (ECPA, Public Law 94-385). PNNL analyzed the cost-effectiveness of changes in Standard 90.1 from 90.1-2007 to 90.1-2010, as applied in the United States. During the development of new editions of Standard 90.1, the cost-effectiveness of individual changes (addenda) is often calculated to support the deliberations of Standard Standing Project Committee (SSPC) 90.1. The process does not include analysis of the cost-effectiveness of the entire package of addenda from one version of the standard to the next. Providing States with an analysis of cost-effectiveness may encourage more rapid adoption of newer editions of energy codes based on Standard 90.1. This information may also inform the development of future editions of Standard 90.1.

Focus: Code Development
The Energy Conservation and Production Act provides that whenever the ASHRAE Standard 90.1-1989, or any successor to that code is revised, the Secretary of Energy must determine whether the revised code would improve energy efficiency in commercial buildingsThe U.S. Department of Energy has performed both a quantitative analysis of the likely impacts of the revised code on the energy efficiency of seven categories of new commercial buildings, compared to the 1989 edition, and a non-quantitative assessment of the comparative stringency of those elements of the revised code that could not be analyzed quantitatively.The quantitative analysis concluded that the1999 revision of the code would likely reduce the source energy consumption of new commercial buildings by approximately 5.9 percent. Site energy savings were estimated to be approximately 3.9 percent. The comparative assessment of those elements of the 1989 and 1999 revised codes that could not be quantitatively analyzed also...

The U.S. Department of Energy submitted 56 code change proposals for the International Code Council's (ICC) Code Development Cycle produced the 2012 I-codes. Thirty-two of the proposals were primarily related to commercial buildings, 24 were for residential buildings. The proposals were mainly to the International Energy Conservation Code (IECC) though most of the residential proposals also applied to Chapter 11 of the International Residential Code.The central theme of the DOE proposals is to improve energy efficiency. Additionally, for commercial buildings DOE attempted to make the IECC more consistent with ASHRAE Standard 90.1. Finally, some proposals were not intended to change requirements but rather improve the usability of the codes, fix wording, correct errors, etc.DOE invited discussion on these proposals and on preparations for the ICC code hearings that took place from October 24 through November 11, 2009, in Baltimore, Maryland.The proposals are available for download in...

Duct insulation and sealing, especially insulated supply ducts delivering conditioned air within a building, save energy. The intent of energy efficiency codes, as related to duct insulation and sealing, is to keep mechanically warmed or cooled air as close to a constant, desired temperature as possible and prevent the conditioned air from escaping the duct system while it is being moved to spaces where it is needed. If reduced heat transfer through insulated ducts is accounted for in the heating, ventilating, and air conditioning (HVAC) load calculations, it may even be possible to reduce the size of HVAC equipment.

Many studies have shown that visual inspection of duct seals in residences is not enough. Code now requires a pressure test. Pressure testing ducts as required by the 2009 International Energy Conservation Code is far superior to visual inspection and will definitively confirm that duct leakage is kept to a low level.

Ducts and air handlers should be placed in conditioned spaces when possible. Ducts typically lose substantial amounts of energy from both conduction and leakage; keeping them in a conditioned space minimizes the impact of these losses. Ducts inside a conditioned space must be properly sealed, but are not required to be insulated.

The purpose of this analysis is to assess the relative energy and energy cost performance of commercial buildings designed to meet the requirements found in the commercial energy efficiency provisions of the International Energy Conservation Code (IECC). Section 304(b) of the Energy Conservation and Production Act (ECPA), as amended, requires the Secretary of Energy to make a determination each time a revised version of ASHRAE Standard 90.1 is published with respect to whether the revised standard would improve energy efficiency in commercial buildings. As many states have historically adopted the IECC for both residential and commercial buildings, PNNL has evaluated the impacts of the commercial provisions of the 2006, 2009, and 2012 editions of the IECC. PNNL also compared energy performance with corresponding editions of ANSI/ASHRAE/IES Standard 90.1 to help states and local jurisdictions make informed decisions regarding model code adoption.

There are three approaches to make an addition comply with the energy code:
  • The addition as defined above meets all code requirements. This approach does not require that the original portion of the building meet code requirements.
  • If the building combined with the addition complies with the code, the addition will also comply, regardless of whether the addition complies alone. For example, a sunroom that does not comply with the code is added to a house. If the entire house (with the sunroom) complies, the addition also complies.
  • In the 2000 and 2003 International Energy Conservation Code, additions less than 500ft2 (46.5m2) of conditioned floor area may meet the prescriptive envelope requirements in the table. To use the table, the total area of windows, doors, and skylights cannot exceed 40% of the gross wall and roof area of the addition.

As of the writing of this report, the state of Illinois does not have a statewide building energy efficiency code for residential buildings, although a number of jurisdictions in Illinois have adopted the 2000 International Energy Conservation Code (IECC) or the 2003 IECC.The U.S. Department of Energy requested Pacific Northwest National Laboratory estimate the energy savings, economic impacts, and pollution reduction from adopting the 2006 IECC. This report addresses the impacts for low-rise residential buildings only.

This study includes the impacts of adopting only the building envelope and lighting requirements of ASHRAE Standard 90.1-1999 and applying it only to new commercial construction. This report builds on a previous study that uses prototypical office, retail, and education buildings to estimate life-cycle cost savings estimates per square foot. Office, retail, and education buildings made up over 60% of the total value of new commercial construction in Illinois in 1997.

This report is an update of a previous report, Statewide Savings Projections from the Adoption of a Commercial Building Energy Code in Illinois, completed in September 2002. This updated version incorporates the most recent—as of the writing of this report—gas and electric rates into the analysis.The results of this analysis suggest that adopting and enforcing a commercial building energy code throughout the state of Illinois could produce substantial energy and cost savings, while reducing emissions of greenhouse gases.

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)— representing ASHRAE Standard 90.1 non-...

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.

Plan review and field inspection of 55 new construction commercial buildings determined if the plans complied with the IECC, and if the building was built to the plans and code. Because an energy code had not previously been enforced, personnel were trained to conduct the onsite inspections and collect data on "typical" commercial construction. Compliance issues were identified and documented.
