  • Energy Use Comparison Between ASHRAE Standards 189.1-2009 and 90.1-2010
Document type: Reports and Studies
Publication Date: January 2007
Focus: Compliance
A study of U.S. architects, electrical engineers, lighting designers, and building contractors and their attitudes and compliance rates; sponsored by the Architectural Products Magazine and the Lighting Controls Association. The purpose of the study was to discover to what extent commercial energy codes are being implemented and enforced.

The ASHRAE Standard 90.1 prototype building models were developed by Pacific Northwest National Laboratory in support of the U.S. Department of Energy's (DOE's) Building Energy Codes Program. These prototype buildings were derived from DOE's Commercial Reference Building Models. This suite of ASHRAE Standard 90.1 prototype buildings covers all the Reference Building types except supermarket, and also adds a new building prototype representing high-rise apartment buildings.The prototype models include 16 building types in 17 climate locations for ASHRAE Standards 90.1-2004, 90.1-2007,  90.1-2010, and 90.1-2013. This combination leads to a set of 1088 building models (in EnergyPlus Version 8.0). Also included is a scorecard for each prototype building. The scorecard is a spreadsheet that summarizes the building descriptions, thermal zone internal loads, schedules and other key modeling...

Focus: Adoption
This toolkit was developed by the U.S. Department of Energy’s (DOE) Building Energy Codes Program (BECP) for use by states, municipalities, energy code advocates, policymakers, stakeholders, and all other groups with a vested interest in energy code adoption. This toolkit provides information and resources to help guide adopting authorities through the adoption process and setting minimum requirements for new construction.This toolkit provides some insight into how the adoption process may influence the residential and commercial build communities.

Publication Date: September 2012
Focus: Compliance
The compliance toolkit describes the steps that should be taken by the build community to make sure that their buildings meet the requirements of the energy codes in effect where the buildings are being built and that the building designs are well documented so that the enforcement community can quickly and easily determine if the building meets the requirement of the energy code.

Focus: Adoption, Code Development, Compliance, Enforcement
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.

This report documents the progress indicator (PI) process and analysis that Pacific Northwest National Laboratory (PNNL) developed to evaluate the potential energy savings from the application of ASHRAE Standard 90.1-2010 to building design and construction compared to the application of ASHRAE Standard 90.1-2004. The report describes PNNL’s EnergyPlus simulation framework, and the building prototype simulation models. The combined upgrades from ASHRAE Standard 90.1 -2004 to ASHRAE Standard 90.1-2010 are described, and consist of a total of 153 approved addenda (44 addenda to ASHRAE Standard 90.1-2007 and 109 addenda to ASHRAE Standard 90.1-2010). PNNL reviewed and considered all 153 addenda for quantitative analysis in the PI process. Fifty-three of those addenda are included in the quantitative analysis. This report provides information on the categorization of all of the addenda, a summary of the content, and a more in-depth explanation of the impact and modeling of the 53...

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....

All 109 addenda processed by ASHRAE in the creation of ASHRAE Standard 90.1-2010 from ASHRAE Standard 90.1-2007 were reviewed by DOE, and their combined impact on a suite of 16 building prototype models in 15 ASHRAE climate zones was considered. Most addenda were deemed to have little quantifiable impact on building efficiency for the purpose of DOE’s final determination. However, out of the 109 addenda, 34 were preliminarily determined to have a measureable and quantifiable impact.

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 and...

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.

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.
