Analyzing the Life Cycle Energy Savings of DOE Supported Buildings Technologies
This report examines the factors that would potentially help determine an appropriate analytical timeframe for measuring the U.S. Department of Energy's Building Technology (BT) benefits and presents a summary-level analysis of the life cycle savings for BT’s Commercial Buildings Integration (CBI) R&D program. The energy savings for three hypothetical building designs are projected over a 100-year period using Building Energy Analysis and Modeling System (BEAMS) to illustrate the resulting energy and carbon savings associated with the hypothetical aging buildings. The report identifies the tasks required to develop a long-term analytical and modeling framework, and discusses the potential analytical gains and losses by extending an analysis into the “long-term.”

Annual Performance Assessment and Composite Analysis Review for the ICDF Landfill FY 2008
This report addresses low-level waste disposal operations at the Idaho Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Disposal Facility (ICDF) landfill from the start of operations in Fiscal Year 2003 through Fiscal Year 2008. The ICDF was authorized in the Operable Unit 3-13 Record of Decision for disposal of waste from the Idaho National Laboratory Site CERCLA environmental restoration activities. The ICDF has been operating since 2003 in compliance with the CERCLA requirements and the waste acceptance criteria developed in the CERCLA process. In developing the Operable Unit 3-13 Record of Decision, U.S. Department of Energy Order (DOE) 435.1, 'Radioactive Waste Management', was identified as a 'to be considered' requirement for the ICDF. The annual review requirement under DOE Order 435.1 was determined to be an administrative requirement and, therefore, annual reviews were not prepared on an annual basis. However, the landfill has been operating for 5 years and, since the waste forms and inventories disposed of have changed from what was originally envisioned for the ICDF landfill, the ICDF project team has decided that this annual review is necessary to document the changes and provide a basis for any updates in analyses that may be necessary to continue …

Border Patrol: Checkpoints Contribute to Border Patrol's Mission, but More Consistent Data Collection and Performance Measurement Could Improve Effectiveness
A letter report issued by the Government Accountability Office with an abstract that begins "The U.S. Border Patrol, part of the Department of Homeland Security's Customs and Border Protection (CBP), operates checkpoints on U.S. roads, mainly in the southwest border states where most illegal entries occur. As part of a three-tiered strategy to maximize detection and apprehension of illegal aliens, Border Patrol agents at checkpoints screen vehicles for illegal aliens and contraband. GAO was asked to assess (1) checkpoint performance and factors affecting performance, (2) checkpoint performance measures, (3) community impacts considered in checkpoint placement and design, and (4) the impact of checkpoint operations on nearby communities. GAO work included a review of Border Patrol data and guidance; visits to checkpoints and communities in five Border Patrol sectors across four southwest border states, selected on the basis of size, type, and volume, among other factors; and discussions with community members and Border Patrol officials in headquarters and field locations."

Demonstration Assessment of Light-Emitting Diode (LED) Roadway Lighting at the I-35W Bridge, Minneapolis, MN
This report describes the process and results of a demonstration of solid-state lighting (SSL) technology conducted in 2009 at the recently reconstructed I-35W bridge in Minneapolis, MN. The project was supported under the U.S. Department of Energy (DOE) Solid-State Lighting GATEWAY Technology Demonstration Program. Other participants in the demonstration project included the Minnesota Department of Transportation (Mn/DOT), Federal Highways Administration (FHWA), and BetaLED™ (a division of Ruud Lighting). Pacific Northwest National Laboratory (PNNL) conducted the measurements and analysis of the results. DOE has implemented a three-year evaluation of the LED luminaires in this installation in order to develop new longitudinal field data on LED performance in a challenging, real-world environment. This document provides information through the initial phase of the I-35W bridge project, up to and including the opening of the bridge to the public and the initial feedback received on the LED lighting installation from bridge users. Initial findings of the evaluation are favorable, with minimum energy savings level of 13% for the LED installation relative to the simulated base case using 250W high-pressure sodium (HPS) fixtures. The LEDs had an average illuminance level of 0.91 foot candles compared to 1.29 fc for the HPS lamps. The LED luminaires …

Electron cooling for low-energy RHIC program
Electron cooling was proposed to increase luminosity of the RHIC collider for heavy ion beam energies below 10 GeV/nucleon. Providing collisions at such energies, termed RHIC 'low-energy' operation, will help to answer one of the key questions in the field of QCD about existence and location of critical point on the QCD phase diagram. The electron cooling system should deliver electron beam of required good quality over energies of 0.9-5 MeV. Several approaches to provide such cooling were considered. The baseline approach was chosen and design work started. Here we describe the main features of the cooling system and its expected performance. We have started design work on a low-energy RHIC electron cooler which will operate with kinetic electron energy range 0.86-2.8 (4.9) MeV. Several approaches to an electron cooling system in this energy range are being investigated. At present, our preferred scheme is to transfer the Fermilab Pelletron to BNL after Tevatron shutdown, and to use it for DC non-magnetized cooling in RHIC. Such electron cooling system can significantly increase RHIC luminosities at low-energy operation.

Equal Employment Opportunity: DHS Has Opportunities to Better Identify and Address Barriers to EEO in Its Workforce
A letter report issued by the Government Accountability Office with an abstract that begins "DHS has generally relied on workforce data and has not regularly included employee input from available sources to identify "triggers," the term EEOC uses for indicators of potential barriers. GAO's analysis of DHS's MD-715 reports showed that DHS generally relied on workforce data to identify 13 of 15 triggers, such as promotion and separation rates. According to EEOC, in addition to workforce data, agencies are to regularly consult a variety of sources, such as exit interviews, employee groups, and employee surveys, to identify triggers. Involving employees helps to incorporate insights about operations from a frontline perspective in determining where potential barriers exist. DHS does not consider employee input from such sources as employee groups, exit interviews, and employee surveys in conducting its MD-715 analysis. Data from the governmentwide employee survey and DHS's internal employee survey are available, but DHS does not use these data to identify triggers. By not considering employee input on DHS personnel policies and practices, DHS is missing opportunities to identify potential barriers. Once a trigger is revealed, agencies are to investigate and pinpoint actual barriers and their causes. In 2007, through its …

Health Care Reform: An Introduction
This report provides an introduction to health care reform. It focuses on three predominant concerns--coverage, cost and spending, and quality--and some of the legislative issues within which they likely will be debated, including the scope of reform (particularly whether Medicare and Medicaid should be included); the choice between public and private coverage; whether employment-based insurance should be strengthened, weakened, or left alone; and what role states might play.

Homogeneous and Heterogeneous Reaction and Transformation of Hg and Trace Metals in Combustion Systems
The overall goal of this project was to produce a working dynamic model to predict the transformation and partitioning of trace metals resulting from combustion of a broad range of fuels. The information provided from this model will be instrumental in efforts to identify fuels and conditions that can be varied to reduce metal emissions. Through the course of this project, it was determined that mercury (Hg) and arsenic (As) would be the focus of the experimental investigation. Experiments were therefore conducted to examine homogeneous and heterogeneous mercury oxidation pathways, and to assess potential interactions between arsenic and calcium. As described in this report, results indicated that the role of SO{sub 2} on Hg oxidation was complex and depended upon overall gas phase chemistry, that iron oxide (hematite) particles contributed directly to heterogeneous Hg oxidation, and that As-Ca interactions occurred through both gas-solid and within-char reaction pathways. Modeling based on this study indicated that, depending upon coal type and fly ash particle size, vaporization-condensation, vaporization-surface reaction, and As-CaO in-char reaction all play a role in arsenic transformations under combustion conditions.

Implementation of longitudinal dynamics with barrier RF in BETACOOL and comparison to ESME
The barrier bucket RF system is successfully used on Recycler storage ring at Fermilab. The special program code ESME was used for numerical simulation of longitudinal phase space manipulations. This program helps optimizing the various regimes of operation in the Recycler and increasing the luminosity in the colliding experiments. Electron and stochastic cooling increases the phase space density in all degrees of freedom. In the case of a small phase space volume the intrabeam scattering introduces coupling between the transverse and longitudinal temperatures of the antiproton beam. For numerical simulations of the cooling processes at the Recycler, a new model of the barrier buckets was implemented in the BETACOOL code. The comparison between ESME and BETACOOL codes for a stationary and moving barrier buckets is presented. This article also includes an application of the barrier bucket numerical model for simulation of the luminosity distribution for RHIC colliding experiments. These simulations take into account the specific longitudinal distribution of the bunch and the vertex size of the detector.

Improvement plans for the RHIC/AGS on-line model environments
The on-line models for Relativistic Ion Collider (RHIC) and the RHIC pre-injectors (the AGS and the AGS Booster) can be thought of as containing our best collective knowledge of these accelerators. As we improve these on-line models we are building the framework to have a sophisticated model-based controls system. Currently the RHIC on-line model is an integral part of the controls system, providing the interface for tune control, chromaticity control, and non-linear chromaticity control. What we discuss in this paper is our vision of the future of the on-line model environment for RHIC and the RHIC preinjectors. Although these on-line models are primarily used as Courant-Snyder parameter calculators using live machine settings, we envision expanding these environments to encompass many other problem domains.

Methodology for Developing the REScheckTM Software through Version 4.2
This report explains the methodology used to develop Version 4.2 of the REScheck software developed for the 1992, 1993, and 1995 editions of the MEC, and the 1998, 2000, 2003, and 2006 editions of the IECC, and the 2006 edition of the International Residential Code (IRC). Although some requirements contained in these codes have changed, the methodology used to develop the REScheck software for these five editions is similar. REScheck assists builders in meeting the most complicated part of the code─the building envelope Uo-, U-, and R-value requirements in Section 502 of the code. This document details the calculations and assumptions underlying the treatment of the code requirements in REScheck, with a major emphasis on the building envelope requirements.

Nonproliferation and Threat Reduction Assistance: U.S. Programs in the Former Soviet Union
This report focuses on funding for threat reduction and nonproliferation programs in the states of the former Soviet Union. Although the United States has expanded its efforts to programs that seek to assist other nations in securing nuclear, biological, and chemical weapons materials, the overwhelming majority of U.S. funds still support programs in the former Soviet states. Nevertheless, because U.S. funding and focus has shifted in recent years, this report provides only a partial view of U.S. nonproliferation and threat reduction programs.

Novel Nanocrystalline Intermetallic Coatings for Metal Alloys in Coal-fired Environments
Intermetallic coatings (iron aluminide and nickel aluminide) were prepared by a novel reaction process. In the process, the aluminide coating is formed by an in-situ reaction between the aluminum powder fed through a plasma transferred arc (PTA) torch and the metal substrate (steel or Ni-base alloy). Subjected to the high temperature within an argon plasma zone, aluminum powder and the surface of the substrate melt and react to form the aluminide coatings. The prepared coatings were found to be aluminide phases that are porosity-free and metallurgically bonded to the substrate. The coatings also exhibit excellent high-temperature corrosion resistance under the conditions which simulate the steam-side and fire-side environments in coal-fired boilers. It is expected that the principle demonstrated in this process can be applied to the preparation of other intermetallic and alloy coatings.

Performance Analysis of Memory Transfers and GEMM Subroutines on NVIDIA Tesla GPU Cluster
Commodity clusters augmented with application accelerators are evolving as competitive high performance computing systems. The Graphical Processing Unit (GPU) with a very high arithmetic density and performance per price ratio is a good platform for the scientific application acceleration. In addition to the interconnect bottlenecks among the cluster compute nodes, the cost of memory copies between the host and the GPU device have to be carefully amortized to improve the overall efficiency of the application. Scientific applications also rely on efficient implementation of the BAsic Linear Algebra Subroutines (BLAS), among which the General Matrix Multiply (GEMM) is considered as the workhorse subroutine. In this paper, they study the performance of the memory copies and GEMM subroutines that are critical to port the computational chemistry algorithms to the GPU clusters. To that end, a benchmark based on the NetPIPE framework is developed to evaluate the latency and bandwidth of the memory copies between the host and the GPU device. The performance of the single and double precision GEMM subroutines from the NVIDIA CUBLAS 2.0 library are studied. The results have been compared with that of the BLAS routines from the Intel Math Kernel Library (MKL) to understand the computational trade-offs. The …

Project Response To ASME Question for Comparison of Pure Oxy-Firing to Diluted Oxy-Firing
High flame temperature oxy-combustion and low flame temperature oxy-combustion are the two primary types of oxy-combustion, which is the combustion of fossil fuel with oxygen instead of air. High flame temperature oxy-combustion results in increased radiant energy, but heat flux at the water walls has been demonstrated to be maintained within design parameters. Less fossil fuel is used, so less CO{sub 2} is produced. Latent and sensible heat can be partially recovered from the compressors. CO{sub 2} capture costs are decreased. Evenly distributed heat avoids creating hot spots. The NETL IPR capture system can capture 100% of the CO{sub 2} when operating at steady state. New boiler designs for high flame temperature oxy-combustion can take advantage of the higher flame temperatures. High flame temperature oxy-combustion with IPR capture can be retrofitted on existing plants. High flame temperature oxy-combustion has significantly improved radiant heat transfer compared to low flame temperature oxy-combustion, but heat flux at the water walls can be controlled. High flame temperature oxy-combustion used with the NETL's Integrated Pollutant Removal System can capture 95%-100% of the CO{sub 2} with heat recovery. These technologies create CO{sub 2} capture cost savings, and are applicable to new design and existing design boilers.

Statistical Analysis and Interpretation of Building Characterization, Indoor Environmental Quality Monitoring and Energy Usage Data from Office Buildings and Classrooms in the United States
Three independent tasks had been performed (Stetzenbach 2008, Stetzenbach 2008b, Stetzenbach 2009) to measure a variety of parameters in normative buildings across the United States. For each of these tasks 10 buildings were selected as normative indoor environments. Task 1 focused on office buildings, Task 13 focused on public schools, and Task 0606 focused on high performance buildings. To perform this task it was necessary to restructure the database for the Indoor Environmental Quality (IEQ) data and the Sound measurement as several issues were identified and resolved prior to and during the transfer of these data sets into SPSS. During overview discussions with the statistician utilized in this task it was determined that because the selection of indoor zones (1-6) was independently selected within each task; zones were not related by location across tasks. Therefore, no comparison would be valid across zones for the 30 buildings so the by location (zone) data were limited to three analysis sets of the buildings within each task. In addition, differences in collection procedures for lighting were used in Task 0606 as compared to Tasks 01 & 13 to improve sample collection. Therefore, these data sets could not be merged and compared so effects …

Synthesis and Evaluation of CO2 Thickeners Designed with Molecular Modeling
The objective of this research was to use molecular modeling techniques, coupled with our prior experimental results, to design, synthesize and evaluate inexpensive, non-fluorous carbon dioxide thickening agents. The first type of thickener that was considered was associating polymers. Typically, these thickeners are copolymers that contain a highly CO{sub 2}-philic monomer, and a small concentration of a CO{sub 2}-phobic associating monomer. Yale University was solely responsible for the synthesis of a second type of thickener; small, hydrogen bonding compounds. These molecules have a core that contains one or more hydrogen-bonding groups, such as urea or amide groups. Non-fluorous, CO{sub 2}-philic functional groups were attached to the hydrogen bonding core of the compound to impart CO{sub 2} stability and macromolecular stability to the linear 'stack' of these compounds. The third type of compound initially considered for this investigation was CO{sub 2}-soluble surfactants. These surfactants contain conventional ionic head groups and composed of CO{sub 2}-philic oligomers (short polymers) or small compounds (sugar acetates) previously identified by our research team. Mobility reduction could occur as these surfactant solutions contacted reservoir brine and formed mobility control foams in-situ. The vast majority of the work conducted in this study was devoted to the copolymeric thickeners …
