Buildings account for almost 40% of the energy used in the United States and, as a direct result of that use, our environment and economy are impacted. Building energy codes and standards provide an effective response. The Building Energy Codes Program designed the Adoption, Compliance, and Enforcement (ACE) Learning Series for those in the building industry having the greatest potential to influence the adoption of and compliance with building energy codes and standards. Each toolkit in the ACE Learning Series delivers essential information to enable designers, specifiers, builders, building owners, policy makers, code officials, and others involved in building design and construction to understand the important role building energy codes play in helping us all address our energy, economic, and environmental challenges.

The Advanced Energy Design Guides (AEDGs) are a series of publications designed to provide recommendations for achieving energy savings over the minimum code requirements of ASHRAE Standard 90.1. This is the first step in the process toward achieving a net zero energy building—defined as a building that, on an annual basis, draws equal or less energy from outside resources than it provides using on-site, renewable energy sources. The guides have been developed in coordination with the following organizations: the American Institute of Architects, the Illuminating Engineering Society of North America, the U.S. Green Building Council, and the U.S. Department of Energy. The New Building Institute participated in the development of the initial guide.

More information on the AEDGs may be found on the Building Technologies Office Commercial Buildings website.

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.

Commercial and residential buildings account for approximately 41% of all energy consumption and 72% of electricity usage in the United States. Building energy codes and standards set minimum requirements for energy-efficient design and construction for new and renovated buildings, assuring reductions in energy use and greenhouse gas emissions over the life of buildings. The U.S. Department of Energy (DOE), through the Building Energy Codes Program (BECP or the Program), supports the improvement of energy efficiency in buildings.

BECP periodically assesses the impacts of its activities by estimating historical and projected energy savings, consumer savings, and avoided emissions. The Pacific Northwest National Laboratory (PNNL) conducted the codes benefits assessment in support of the BECP. Underlying the assessment is a series of calculations that estimate and compare energy savings under two scenarios: "with BECP" and "without BECP." The analysis covers the years 1992-2040...

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.

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.

Ensuring compliance with HVAC control requirements is difficult, as controls can be difficult to identify on plans or in the building, yet it is a crucial task. HVAC controls are a key driver of building performance and without compliance and enforcement activities, the code requirements may be ignored, overlooked, or misunderstood.

This guide provides an aid that will make it easier to apply the heating, ventilation, and air conditioning (HVAC) control requirements found in building energy codes and addresses requirements defined by 2009 and 2012 editions of the International Energy Conservation Code (IECC) and ASHRAE Standard 90.1-2007 and ASHRAE Standard 90.1-2010.

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...
